A Decentralized Real Estate Data Exchange & Real Estate Transaction Application
Imbrex: referring to the platform, imbrex
IMBREX: referring to the token, IMBREX
Real property, defined as anything owned by a person or entity in regard to land, real estate, the improvements on it, or the right to use or inhabit it, has existed at least since man first settled the ancient lands of Mesopotamia in 4500 BCE. Real estate—the transaction of value assigned to land and living space—is one of the oldest and most essential industries in the world. Almost every single human being relies on it for their most basic needs. Since the time of those early settlements, there have been two major pillars of a real estate transactions that also constitute the focal point of the imbrex ecosystem:
For decades leading up to the digital revolution, obtaining reliable property information remained difficult. Today, with advances in technology, data has become easier to create and transmit across industries. However, in the world of real estate, data is still highly controlled, poorly maintained, and governed by centralized organizations. This results in exorbitant transaction and listing fees, and data walled into silos that are not interoperable within the fragmented global real estate industry ecosystem.
Imbrex believes the real estate industry is ready to move beyond traditional closed storage systems, where its value is limited to the interest of the entity controlling it. Imbrex envisions a world of shared information, where individuals can monetize and realize the true value of their data, and it isn’t limited by central barriers.
Imbrex will begin by building a global real estate data exchange, an information layer that is accessible to everyone. The database will minimize listing fees and maximize listing exposure. It will eliminate spam through community participation. It will provide incentive-based curation registries that will open up new data channels. In later phases, imbrex will introduce programmable data escrow contracts, a way to efficiently manage transaction documentation, communication and execution.
Imbrex can be thought of in two ways:
Firstly: a global listing portal in which users own and control their data, and have access to a global ecosystem of information.
Second: A user-curated real estate marketplace. It’s analogous to Wikipedia (user-curated information) meets Amazon (global marketplace). Atop that, users who curate data earn rewards for their participation.
Groundbreaking recent advances in peer-to-peer data distribution and blockchain technology give imbrex the ability to provide universal access to real estate information via a digital marketplace, and streamline the transaction process.
1.1 What is a Listing Portal?
A listing portal acts as a platform for the orderly correlation and dissemination of listing information to better serve brokers’ clients, landlords, tenants, and the public. A listing portal is a suite of services that enables real estate brokers, landlords and sellers to establish contractual offers of compensation, that facilitates cooperation with other transaction participants, and that accumulates and distributes listing information.
1.2 Evolution of a Listing Portal
Listing Service 1.0 (Pre-Internet)
Pre-internet, the real estate industry relied on print for dependable real estate information. Print releases were bi-annual with dated property information.
Listing Service 2.0 (Post-Internet, Pre-Blockchain)
Most countries have a handful of dominant online listing portals. Listing fees vary world-wide. We’ll provide one example in the United States:
We can approximate that the average subscriber is paying at least $30.00/listing per month, or $360.00/listing per year:
300/10 = 30
30 * 12 = 360
Users subscribing to platinum services pay an estimated increase of approximately $520.00/listing per month or $6,240.00/listing per year:
30+ 400 + 90 = 520.00
520 * 12 = 6,240.00
Common complaints include a lack of price transparency, poor user experience, and an excess of stale information.
Internal Solutions (That Lead to More Problems )
Due to cost and the lack of database interoperability, firms began developing their own portal systems. This proved counterproductive and widened the gap of incongruity.
1.3 Listing Portal 3.0: Overview of imbrex’s Data Exchange
Imbrex provides a new type of listing portal, one where data is collected, shared and accessible to all participants. Imbrex's shared database (Imbrexer) is decentralized by nature, with firms running independent imbrex nodes that give them the ability to store data locally and tap into the wider ecosystem—offering both internal and external functionality. The imbrex node is a combination of the Imbrexer, Ethereum and IPFS nodes.
The value to the firm includes ownership, control and portability of their data, access to new curation feeds, spam reduction, and reward systems that compensate users for participating in the network. For every listing not marked as spam by other community members (see imbrex’s Spam Registry below) the Listing Rewards Contract pays the user in IMBREX token. Fees incurred on imbrex are recirculated back into the Listing Rewards Contract fueling a perpetual cycle of fees and rewards.
Traditional listing portals generate revenue from collecting user data and charging high subscription fees to publish to their platform. The user delivers value (through providing data), but the listing portal is the financial beneficiary. On imbrex, listing fees are nominal ($0.10-$0.20 per listing). This fee is enacted to fund the mitigation of spam. The more listings a user publishes that are not marked spam (see Spam Registry below), the more imbrex rewards they earn. The more listings on imbrex, the more eyeballs. The more eyeballs, the more demand for the IMBREX token.
Value is initially driven by listors, and they are the beneficiaries with cheaper, cleaner data. In addition, they, and other users, can monetize their data through an open marketplace that includes market studies, inspection reports, appraisals, and advertising space. Listing exposure will go from regionally siloed and benefitting a few, to globally accessible, locally sourced, comprised of more reliable data and available with richer data sets, rendering imbrex one large, homogenous database that is not bound by countries or borders.
1.4 Why imbrex is Starting with Listings
Smart contracts provide a groundbreaking way to transact real estate. They offer the real estate industry the ability to transact property faster, cheaper, and more securely. However, the industry cannot successfully take full advantage of the technology until existing infrastructure problems are addressed.
One major issue is universal property identification. This is why imbrex is starting with listings. First, the Imbrexer, with its open-access design, creates the interoperability layer between imbrex nodes. The Imbrexer gives firms, brokers and companies alike the ability to own, maintain and share real estate information quickly and easily. Second, it provides an opportunity to create a global property identification system that is not owned or controlled by a centralized organization. This is a pivotal step toward later enacting transaction processes.
The Ethereum ecosystem has already laid much of the groundwork of establishing a safe, secure network on a global scale. Imbrex—and entire the real estate industry—can capitalize on this infrastructure by building the universal property ID layer. The property identifier can later be used for title, firms, brokers, lending, insurance and technology companies to search, track and transact property. Once the property ID system is established, the industry can effectively engage in smart transactions.
By starting with listing data, imbrex can automatically give each property a unique ID. This ID is open source and accessible to anyone, anytime for free, and creates the ideal basis upon which to create a functional and deep ecosystem.
Imbrex envisions a 3-year timeframe to deploy our initial mission:
Phase 1: Pilot: Listing Portal & Property Identification, Data Exchange, Curation Registries
Phase 2: Scaling
Phase 3: Transactions: Escrow Contracts
Imbrex’s roadmap takes into account the current immaturity of the Ethereum ecosystem, increasing government participation and the time, education and experimentation required to attract and initiate users.
Blockchain technology is in its infancy. The basic infrastructure is still being built and tested. Thus, imbrex will focus the first 12 months launching our Pilot Program in a few test markets. The Pilot will consist of participants exchanging data through the Imbrexer. During this period, imbrex will introduce and test its Spam Registry which is modeled after AdChains Token Curated Registries https://medium.com/@ilovebagels/token-curated-registries-1-0-61a232f8dac7 .
We recently began our go to market strategy, focusing on a top-down bottom-up approach. We met with several major firms and many more brokers to gain feedback on our existing alpha. imbrex will gradually on board users during the Pilot through a series of digital campaigns, conferences, speaking engagements and canvassing.
1.5 Transactions: Escrowing Data
A major flaw often encountered in the real estate transaction process is miscommunication between participating parties. There are various types of documentation that must be produced during the transaction process, and the path of these deliverables often takes circuitous routes. Documents include credit reports, bank statements, insurance estoppels, government identification, inspection reports, survey data and many other types of sensitive information. Typically, these requests are coming from attorney’s, lenders, brokers and insurance companies.
In transit, these documents often take several email steps before reaching their destination, and it is difficult for transaction participants to accurately track documentation collection. In addition to a poor tracking system, the buyer/seller/lessor/lessee risks their data being released through the carelessness of one of the transaction participants.
Imbrex will offer, via its application layer, an escrow service that will mitigate future security leaks and provide an efficient and reliable mechanism to track information flow. On the transactions page, users can create document lists, designating which participant is responsible for producing which document. All transaction participants will upload their documents via imbrex’s Data Escrow Contract. The documents flowing through imbrex’s Data Escrow Contract will be encrypted and stored via IPFS.
The contract will produce a private key that the uploading participant can distribute to other transaction participants. Transaction participants can track in real time what documents have been collected and what data still needs to be produced. This process will create an open transparent layer that securely tracks sensitive information. Imbrex’s Data Escrow Contracts will eventually have the ability to escrow deposits, payments and allowances.
2.1 What is the Blockchain?
The blockchain is a distributed database or public ledger that gained popularity following the release of Bitcoin. It maintains a continuously growing list of all the transactions in a particular network that have ever been executed. The “blocks” are added in chronological order with cryptography to prevent tampering, thus becoming an indelible record of every transaction in the network and accessible to every participant .
2.2 What is Ethereum?
The Ethereum system can be described as a single shared computer that is run by the network of users, on which resources are parceled out and paid for in Ether. In essence, it’s a world computer.
2.3 Why is imbrex building on Ethereum?
Data needs to be on a server. A server is generally owned or leased by a corporation.Therefore, the individual relinquishes control of their data. This leads to increased costs with low accessibility and virtually no interoperability between systems.
We now have the means of decentralizing data. BitTorrent, Swarm, and IPFS can do that on their own, but the blockchain provides the ability to organize and order the data with no central authority. Ethereum provides a means to mesh together the blockchain, data distribution, and currency all under one roof. Ether, which is the medium used to transact on the Ethereum Blockchain, can be exchanged for IMBREX tokens, and IMBREX tokens will fuel the application. This is the absolute value imbrex sees for blockchain and Ethereum technology.
Imbrex is building on the Ethereum protocol for several reasons. The first is to provide a distributed database where anyone can access real estate information for free.
Distributed databases provide two advantages:
1. The user always owns and has access to their information. Third party advertisements,
especially those of competing brokers, will never exist on a listees page unless they
initiate private advertising.
2. Price Stability: No central authority owns the information, eliminating capital controls on the data.
Ethereum also provides a means for tokenized currency. Imbrex is utilizing the tokenized aspect of Ethereum to reward contributors for providing and curating content while offering a digital exchange where real estate data can be freely traded.
While imbrex's database stores all active listings for 90 days, it is possible to build a comprehensive history of each individual parcel ever listed on the platform.
2.4 Data Distribution
Since the 1990’s, the HTTP protocol has been a useful tool to send and receive data packets from one or more central servers to the requesting node.
Today, we distribute much larger packets of information. If too many requests are made servers become overwhelmed. The result is increased latency, downtime, and maintenance requirements. The costs are passed from owner to user. In 2017, the HTTP protocol is inefficient. We’re at an inflection point where not all nodes need to communicate through centralized routes, but rather, can do so peer-to-peer.
The Interplanetary File System (IPFS) is a new hypermedia distribution protocol, addressed by content and identities. IPFS enables the creation of completely distributed applications. It aims to make the web faster, safer, and more open.
2.6 Benefits to imbrex
IPFS provides a means for imbrex to distribute real estate data in a decentralized manner. When a listing or transaction documents are submitted to imbrex, imbrex hashes the data and pushes the content to IPFS. The data is encrypted and disseminated globally to machines running the IPFS instance. Since the data is distributed and not stored on one single computer, costs are reduced and access is universal. The architecture of IPFS provides a built in governor so imbrex (or any other applications built on top of imbrex) cannot charge large sums of money or deny access to users.
Reed Hastings built Netflix with the idea of streamlining the way users view and receive digital content. First, Hastings exercised value out of the existing technological infrastructure. Users rented DVDs online and had them physically delivered via US mail, thus avoiding the inconveniences of traditional retail (time, travel, and late fees). Netflix grew exponentially as infrastructure matured and delivery went from physical to digital.
Imbrex is taking a similar long-term approach. Starting with the foundation laid by Ethereum, imbrex will begin assembling the shared database and opening up the data exchange through User Curated Registries. As the database scales and the network stabilizes, imbrex will introduce data escrow services that will secure documentation sharing and provide the ability to store deposits, payments and allowances.
The Pilot will be focused in 2-4 markets. Over the 12 month period, imbrex will release the Universal Property Identifier, Listing Rewards Contract, Rating Contract, Subscription Contract, Spam Registry, Data Escrow Contract and 90 Cliff.
Imbrex’s Pilot will consist of a six-feature release:
1. Universal Property Identifier (UPI)
For every property listed in the Imbrexer, a unique property identifier will be generated. The identifier will serve as that property’s genesis record for all future transactions. The UPI will be open source.
2. Listing Rewards Contract
Pays x IMBREX tokens to every listing uploaded that is not voted as spam.
3. Rating Contract
Imbrex will deploy a trust system based on user ratings. Ratings will establish user-credibility benchmarks that will be used throughout imbrex’s ecosystem for listing validation, Registries and voting.
4. Subscription Contract
Imbrex’s Subscription Contract will be deployed. To help with user onboarding through the application layer, we’ve designed a non-crypto subscription model. Funds collected through the subscription model will be used to automate transaction costs so the user does not have to to obtain ETH in order to cover gas.
5. Imbrex Spam Registry
Imbrex will enact its default Spam Registry system.
6. Data Escrow Contract
The Data Escrow Contract will provide a trustless environment for users to exchange transaction data.
7. Imbrex 90-day Cliff
Idle listings that have not been updated (via a transaction) for 90 days will be dropped from the Imbrexer.
The current state of the Ethereum Network cannot handle significant increases in transaction flows. Imbrex is working on various scaling solutions, to take features like listing edits off chain. The team is exploring state/payment channels proposed by Raiden and following other innovative solutions proposed by members like Matthew Di Ferrante.
4.4 Transactions: Escrow Contracts
One of the biggest transaction killers in real estate is time. Time delays often occur due to poor communication channels and document distribution. Bank statements, estoppels and inspection reports are just a few items that get passed around between the buyer, seller, landlord, lessee, bank, insurance company, appraiser, tax assessor and inspector. These documents are often passed through email and accurately tracking them is difficult. Imbrex solves this problem through its Escrow Contracts.
First, all participants will visit the Transactions page on imbrex’s application layer. Here, participants will create a list of the necessary documentation that needs to be produced and by which participant. Documents can include
Each user will upload their documentation which will be bundled into the Escrow Contract, encrypted and pushed to IPFS. The contract will generate a private key, which the uploading participant can share with other transaction participants that require access to the data. The documents will only be accessible via the private key and for the duration chosen by the uploading participant.
Imbrex’s Escrow Contracts will have the ability to track deposits, payments, and allowances via the IMBREX token or cryptocurrency of the transaction participants choosing.
Imbrex will never store the documents or funds that travel through its Escrow Contracts. Instead, the data and transaction records will be encrypted and sent via IPFS. The uploading participants will have full control and ownership of the document, including when it can be destroyed and who will have access to it.
Imbrex Technology Stack:
Data Escrow Contract
Listing Rewards Contract
4.5 Token Allocation
Founders and Angels will have a two year vesting period at no more than 1,000,000 IMBREX tokens a year. This is to ensure price stability amongst the IMBREX token.
4.6 Token Utility
Phases 1 and 2
1. Listing Rewards: Registered users are paid x IMBREX tokens for every listing they contribute to the database that is not flagged and voted as spam.
2. Imbrex Default Spam Feed: A user uploads a listing. It goes live on the platform and other users have a one week duration period to mark it as spam. To mark a property as spam, the user must pay x IMBREX tokens. The listing then goes into a three-day arbitration period where other IMBREX token holders can vote (blindly) to approve or disapprove the listing as spam. If approved, the listee gets the listing reward and the flagger loses their deposit. The loosing pool loses their IMBREX tokens and it is distributed to the winning pool. If the listing is voted as spam, the flagger receives the listing reward and pool that voted the listing as spam receives the losing pools IMBREX tokens.
3. Flagging Deposit: Users pay x IMBREX tokens to flag a listing they believe is spam. If the listing is voted as spam by the community, the flagger will receive the listing reward. If the listing is not voted as spam by the community, the flagger loses their deposit (see imbrex’s Spam Registry).
4. Spam Voting Pools: Users pay x IMBREX tokens to vote for or against spam. All votes are blind and tallied up at the end of the seven day voting period. The pool with 51% or more of the votes will win the losing pools IMBREX token deposits. These deposits are distributed evenly amongst the winning pool.
5. Listing Spam Reducer (LSR) Deposit: Users pay x IMBREX tokens when submitting a new listing. The LSR is to prevent gaming of the Listing Rewards Contract. The listing reward will always be higher than the LSR.
6. Curation Registry Application Fee: By default, users are subscribed to imbrex's Spam Registry. imbrex’s Spam Registry is a screening process where spam listings are weeded out of the application query. Other users can apply, be vetted and approved by other community members, and create their own Curated Registries. The application fee is set in x IMBREX tokens. Application Fees are redistributed back into the Listing Rewards Contract.
7 . Curator Approval Voting Deposit: Users can vote (blindly) on which users to approve/disapprove for Curation Feeds. Voting to approve/disapprove user Applications to Curate requires a IMBREX token deposit. For example, Bob lives in New York and believes he can filter spam better than imbrex’s Spam Registry. Bob applies, via imbrex’s application layer, to become Manhattan's spam curator for the downtown office market. Bob files his application and deposits x IMBREX tokens into the Curation Smart Contract. Over a one week period, users vote blindly with IMBREX tokens to approve or disapprove Bobs application. If Bob is approved, the disapproving pool loses their IMBREX tokens which are distributed evenly to participants in the approving pool. Users subscribed to Bob’s Curation feed now see New York query results through Bob’s Curation Feed. Bob can monetize his Curation Feed through advertising and listing promotions.
8. Curation Ad: Users that create Curation Feeds can monetize their Feed by charging IMBREX tokens for promoting listings and advertising throughout their feed.
9. Market Sponsorships: Users pay x IMBREX tokens to sponsor a segment markets. These funds are recycled back into the Listing Rewards Contract.
10. Featured Properties: Users pay x IMBREX tokens to Curators to feature their listings.
11. Broker & Landlord Professional Profiles: Users pay x IMBREX tokens to create a professional profile. Users with Professional Profiles are searchable in the imbrex Database. These funds are recycled back into the Listing Rewards Contract.
4.7 Imbrex Node
Imbrex Node’s are a combination of the Imbrexer, IPFS and Ethereum nodes.
Why Run a imbrex Node?
Today, users can visit a firm's website and browse "the firm’s" data. In fact, that data is not being stored by the company at all, but rather a third party listing portal. This process complicates the firm’s process for uploading listing data for several reasons:
Within the imbrex ecosystem, firms can run a imbrex node, store their information locally and own it. The broker can upload listing information one time on the firm's branded website, which stores the data on their imbrex Node. This information can have daily pushes and pulls to nodes outside their own. The firm can choose which data they want to participate to the global system, and also have the ability to pull in outside information. Each firm that runs a imbrex node further decentralizes the ecosystem ensuring the continuation of low fees and latency.
Benefits of running a imbrex Node
4.8 Listing Rewards
Listing Rewards provide a distributed means to build and scale the database. Anyone can upload a listing to imbrex. Each upload by the user will be eligible for the Listing Reward. Listings that are not flagged/voted as spam will receive the Listing Reward.
4.9 Imbrex’s Default Spam Registry
Spam is a rampant problem all over the internet, and the eradication of such on the imbrex platform is an important endeavor. Traditional real estate portals are filled with stale, fake and misinformed data. In our research we've found most major review websites are able to weed out approximately 70%-80% of spam through custom algorithms . However the last 20%-30% must be curated by platform staff, which is costly and provides unbalanced incentive structures.
It becomes even more difficult as a platform scales outside its native geographic region. Imbrex is taking a different approach. We believe real estate is a local business. With the blockchain, we can employ new incentive structures that rewards users to localize spam filtration, thus avoiding extensive hiring and unnecessary salaries. Imbrex is decentralizing spam filtration using Registries and Game Theory.
Users that submit listings to imbrex's application layer will be eligible to receive the Listing Reward. The process will utilize a unique Curation system where other IMBREX token holders vote (blindly) on whether to approve or disapprove a listing as spam. The process will look like the following:
The flagor’s "flag" will count as one vote to disapprove, and the listor’s vote will count as one vote to approve.
In the case that listing x is approved as spam:
4.10 Voting Contract
Anytime a voting scheme is initiated, a 1:1 vote is automatically issued in the Voting Contract. One to the flagger/challenger and one to the listee/curator. This creates a balanced starting point for the voting process to commence.
4.11 User Curation Registries
Decentralization and the use of crypto-economics gives imbrex the ability to take data aggregation to new levels. Imbrex will employ User Curation Registries, which is a derivative of our Spam Registry. This will further reduce spam and expand the available information thus leading to the initial stages of the global real estate data marketplace.
How it works
Through imbrex's application layer, users can apply to curate spam or create new types of data feeds. The user will apply then be vetted by the community. If the candidate is approved, they can begin curating data via their Curation Registry. If the user provides value to the network they can monetize their registry via promotions and advertising.
Joe has been an office broker in New York City for 25 years. Joe regularly reviews imbrex's office listings and finds properties that make it through imbrex's Spam Registry. Joe decides to file an application to create Manhattan's Office Spam Registry. On his application, Joe lists his experience and the ways in which he can add value to the network. To submit his application, Joe deposits x imbrex. Joe’s application is routed to imbrex’s Curation Registry Applications Page. Over a one week period, imbrex community members can vote to approve or disapprove Joe. As in imbrex’s Default Spam Registry, all votes are blind. To vote, users pay x IMBREX tokens.
At the end of the one week period all votes are revealed and Joe is either approved or disapproved by the community. If Joe is approved, the disapproving pool loses their IMBREX tokens which will be distributed evenly to the approving pool. Joe’s deposit is routed to the Listing Rewards Contract and Joe can begin curating office listings for New York City. Joe can monetize his feed if he is able to accrue a following through listing promotions and advertising.
Users can challenge other user Curation Registries if they believe they are not doing an optimal job. The application is similar to the application process of submitting a new User Curation Registry, and will be voted on over a one week period, where like Joe's application, users will vote blindly on whether to approve is disapprove the challenger.
If the challenger is approved by the community, Joe's user rating will decrease, and the challenger will be granted the opportunity of replacing the previous Registrar. If the challenger is able to reach the same amount of followers as Joe within "x" timeframe, they will be listed number #1 position on the application layer for that market. Imbrex’s application layer will show up to three Curation Registry’s per market and market segment.
Initially, there will be one curator per market, per segment:
4.13 Open Curation Reports
Users can aggregate and assemble new types of data, which can then be sold to other users within the community. Each market will have a reports page where users can post data reports to sell to other users. The listing seller will upload the data via imbrex’s Reports Contract. The reports contract will escrow the listing data via IPFS and the buyer’s payment.
4.14 Imbrex Subscription Contract
Imbrex will offer a subscription based model that will handle all backend transactions for paying subscribers.
Imbrex believes people should be in control of their data. Users should have the ability to buy and sell this data with other people in the industry. With today’s advances in storage, bandwidth, distribution, and flexible blockchains like Ethereum, we can rebuild the old systems into cost effective platforms.
On imbrex, users will retain ownership of their real estate data and it will not become a product of a larger corporation. They will earn rewards and collect fees for their data, not the platform. New marketplaces will emerge making it easier to obtain real estate data. A standard property identification system will provide a secure way to transact property digitally. These goals can be achieved with the technology and a proper strategy. The execution of this vision is malleable and geared towards gaining the confidence of imbrex’s users base and regulators around the world. Modularizing development into achievable milestones provides imbrex the ability to build, test and deploy the platform so it can succeed and scale.

8.1 Appendix A Real estate transactions: Today
A buyer, tenant or broker searching for a house, office, warehouse, land or retail space typically begins their search with an online portal. The accessible data is limited before the user hits a paywall. The paywalls consist of annual memberships that enlist high annual fees and collect superfluous data about their customers and their dealings.
After the user subscribes and locates a property, they engage the listing agent to negotiate price. The buyer and seller have their attorneys draft, edit, and finalize the Purchase & Sale Agreement (PSA). Within the PSA are a list of terms the buyer and seller must perform for the transaction to consummate. The buyer is permitted approximately 30-90 days to perform an analysis of the property called due diligence. Due diligence includes, but is not limited to:
The buyer’s lender will conduct:
During due diligence, the seller will perform certain obligations spelled out in the PSA:
Throughout the transaction, the buyer and seller communicate through their banks, attorneys, inspectors and real estate brokers. The chain of communication inevitably leads to delays and increased costs to the buyer and seller.
Once diligence expires and both sides meet their respective obligations, a closing date is set.
The following is a brief list of documents required at closing:
In the US, closing costs average approximately +$10,000 for residential and approximately +$20,000 for commercial (subject to the size of the deal and local tax jurisdictions).
Bob wants to sell a mixed use building in Princeton, New Jersey:
Address: 236 Nassau Street
9 1-bedroom apartments
2 retail units
Net Operating Income: $175,000
Capitalization Rate: 5%
Bob decides to list 236 Nassau Street on his local portal service. After several weeks and no traction, Bob decides to sign up for the portals premium edition (approximately $299.95/month). The premium edition grants Bob access to surrounding property data. After three weeks and no action, Bob decides to obtain a comparable property analysis. Bob pays approximately $90.00 for the service. The information is dated and proves useless. Bob realizes 236 Nassau is at the bottom of the search query. For an additional fee of approximately $399.95 for 30 days, Bob can have 236 Nassau Street listed as "Platinum" on the results page. Bob proceeds with the platinum listing.
Bob is spending approximately $790.00/month or $790.00/per listing on marketing 234 Nassau Street.
Alice’s broker finds Bobs listing on the portal and presents it to Alice. Alice makes an offer of $3,400,000. Bob accepts Alice’s offer and their attorneys negotiate the Purchase & Sale agreement on the following terms:
Alice deposits $175,000 in her attorney’s escrow account. Due to miscommunication between the title agency and bank, closing is delayed two weeks costing both Bob and Alice money in attorney fees and carrying costs. Finally, a closing date is set, and after several hours of paperwork, title is passed. Title is recorded manually at Princeton’s municipal clerk’s office. Alice and Bob paid approximately $40,000 in combined transaction costs and Bob paid approximately $790.00/month in listing fees.

8.3 Appendix C Tokenized Ownership
What if you could trade 1,000 tokens in the Chrysler building like you trade a 1,000 shares of Apple?
The Chrysler building was completed May 27, 1930. Owned by Walter P. Chrysler, it was built to serve as Chrysler's new headquarters. The Chrysler building is 77 floors high and approximately 2,062,772 square feet in office space. The building has changed hands several times since the Chrysler family sold it in 1953. In 1998, Tishman Speyer Properties along with Travelers Insurance purchased the Chrysler building for $220,000,000. In 2001, Tishman sold a 75% stake to Abu Dhabi Investment Council. Today, Abu Dhabi Investment Council owns 90% and Tishman retains 10%.
Redefining Real Estate Ownership: Chrysler Dapp
Let’s say imbrex purchases Abu Dhabi’s and Tishman’s entire stake in the Chrysler building for $3,000,000,000 cash at a 4% capitalization rate:
The Chrysler building is 90% occupied with long term leases averaging $108/SF. The gross income is $200,500,000 per year. Expenses run about 40% or $80,200,500. Thus, the Net Operating Income is $120,000,000.
Blockchain Using Ethereum, imbrex creates a decentralized application called Chrysler Dapp. The Chrysler Dapp creates 1,000,000,000 CHRY tokens. Chrysler Dapp allocates 750,000,000 CHRY tokens (75% of the total supply) to be sold in an upcoming crowdsale. CHRY tokens will be listed at $3.00 per token (valuing the building at $3,000,000,000).
The developers of Chrysler Dapp create an incorporated company called Chrysler Management Inc. Chrysler Management Inc. will be the managing entity of the Chrysler building, responsible for management, leasing and legal. Chrysler Management Inc. will retain 100,000,000 CHRY or 10% of the total supply. The remaining 150,000,000 CHRY will be held for capital reserves. Each quarter, Chrysler Management Inc. will convert all positive cash flow (after expenses) to CHRY tokens and deposit them in a community smart contract. The contract will distribute CHRY tokens to stakeholders according the percentage of tokens each stakeholder owns.
In the bylaws between CHRY token holders and Chrysler Management Inc., it will state that each quarter (much like public companies are required by the SEC), Chrysler Management Inc. is obligated to release a detailed income and expense report for that quarter.
Token participants have the opportunity to own a piece of an iconic building in New York City with a potential 10% upside: If Chrysler Management Inc. leases the 10% vacancy, it will increase net operating income which in turn should increase the value of the building: > vacancy + tenant = +NOI = +building value = +CHRY token value
Market equilibrium shows us an increase in value usually creates an increase in price. Conversely, if Chrysler loses a major tenant the token’s value should decrease.
As we’ve seen with recent token sales, prices fluctuate and markets can be highly irrational. However, a physical asset like the Chrysler building can be pegged to the local real estate market offering a more precise determination of value and perceived risk. for example:
ABC Inc. occupies 500,000/SF at $108/SF. Their lease expires and they vacate the Chrysler building. In one deal, the asset loses $54,000,000 in gross annual income. The CHRY token price drops to $1.00 valuing the building at $1,000,000,000. A few sophisticated individuals discover the actual market value (after the loss of ABC Inc.) should be closer to $1,700,000,000: $146,500,000 — $80,200,000 = $66,300,000 NOI at a 4% CAP = $1.657 billion or $1.67 per CHRY token.
The investors can profit from a potential $0.67 upside in token value, long term building appreciation and any increase in value once the remaining 10% vacancy is filled. The same is true if the token value jumps to $4.00 or $4,000,000,000 with no real increase in NOI. Sophisticated investors may short CHRY tokens thus stabilizing value with market equilibrium.
