  • Purchasing a home is a major life milestone for many people, and most people choose to acquire homes via a mixture of directly invested equity dollars and borrowed dollars via a mortgage.
  • One of the most important components in that mortgage is getting a valuation of the underlying asset (in this case the house) so that a certain portion (say 80%) of that value can be loaned to the borrower and secured by the full value of the house.
  • a mortgage cannot be qualified for as the lender is unable to prove that the mortgage is backed by sufficient equity.

  • Embodiments of the disclosed invention enables users to bypass the barriers to entry that have traditionally kept attractive real estate investment opportunities off-limits to all but the most established investors and institutions.
  • an embodiment of the invention is able to provide the benefits of real estate investing and ownership to everyday investors.
  • home equity is the foundation and supporting collateral used to justify the risk of granting the loan. Without sufficient collateral, no loan can be given.
  • the opportunity for the growth in value of the home’s (subject real estate asset's) equity justifies the loan and interested paid.
  • the equity of the home can be used to support future loans often larger than the initial mortgage due to the growth in its value over time.
  • the present invention enables an alternative to the traditional mortgage backed by a single discrete asset.
  • embodiments of the present invention allow for a loan to be supported by collateral comprising of ownership of fractions of many assets (e.g. shares in a REIT or fractional ownership of any number of individual assets in a group). Since fractional asset ownership does not require the purchase of a complete asset, it can be purchased with any amount of starting capital. Additionally, since the fractional assets are still real estate assets, they are less volatile, prone to appreciation, and trusted by lenders therefore, they can be used as collateral for lower interest and higher leveraged loans, similar to traditional mortgages.
  • Such loans can also be used to build equity if (when) the value of the fractional real estate assets and provided dividends increase faster than the accrued interest.
  • embodiments enable a way for home owners and/or investors to begin their journey up the property ladder regardless of the magnitude of initial investment. Giving all individuals the ability to build a substantial amount of wealth without needing to earn more money or reduce their consumption elsewhere has the potential to provide longterm financial security for huge swathes of the population that have historically struggled to achieve this.
  • the first issue is that of valuation, without up to date knowledge of the value of the asset to be used as collateral a loan cannot be secured.
  • a single complete asset is straightforward to valuate and can often be partially done during an in-person inspection by an assessor.
  • a direct in person valuation is impractical if not impossible.
  • the second issue is that of verifiability. Ownership of a single real property asset is officially recorded, for example at the registry of deeds. A loan provider knows they can trust these recordings to verify that a loan requester actually owns the equity to be used as collateral.
  • Embodiments of the invention include methods, and corresponding systems, that are able to evaluate a portion of many different real estate assets and create a verifiable record of ownership of that portion of different assets. This enables an individual to obtain, at a far lower price, real estate assets and leverage those assets as collateral for a loan.
  • Embodiments of the invention include a blockchain based system that stores data regarding the ownership and value of portions or fractions of a real estate asset.
  • the real estate asset may be comprised of disparate individual assets and be structured as a real estate investment trust (REIT) or an alternative manner of asset grouping that offers shares that provide to ownership of a portion of the total real estate assets.
  • Embodiments store data about the overall value of the real estate assets and the value of its component properties and/or assets.
  • Embodiments of the invention use both the intrinsic characteristics of the component assets and current market conditions to determine the value of the component assets and also the value of the total real estate asset or REIT.
  • Embodiments update the stored data to reflect any change in valuation. This process ensures that the valuation of both the total real estate asset and any portion or fraction thereof is accurate and up to date, setting the foundation for use as loan collateral.
  • An individual can purchase a portion, or shares, of the real estate asset for a proposed price.
  • Embodiments of the invention calculate, using the stored valuation data, the fraction of the real estate asset, or number of shares of the REIT or grouped asssets, the individual should receive ownership of in exchange for the purchase price.
  • the embodiment creates a record of ownership of the purchased portion of the real estate asset and a record that the purchased portion has been transferred to the purchasing individual.
  • embodiments store this record of ownership on a blockchain.
  • ownership in a portion of the real estate asset is denoted by a record of ownership of a coin or token of a cryptocurrency built on the blockchain.
  • the embodiment By storing the record of ownership of a portion of the real estate asset on the blockchain, the embodiment creates verifiable and immutable proof that an individual owns a specific asset that has a specific value backed by tangible real estate. This solves the two problems discussed previously, valuation and verification, and allows for the purchased portion of the real estate asset to serve as loan collateral.
  • a loan that utilizes fractional real estate asset ownership as collateral and enabled by embodiments of the present invention has several advantages over a traditional mortgage secured by a single property.
  • the loan is disassociated from the underlying real estate where the loan holder lives. This enables individuals to begin building real estate equity without the need to commit to a specific and illiquid often pricy home asset.
  • embodiments of the present invention enable loans to be secured by fractional ownership of a distributed real estate assets
  • the loan underwriter still gets the same risk profile as a traditional mortgage, or potentially a better more diversified risk profile, justifying low interest rates, but the loan receiver does not need to purchase an asset as expensive as a complete real estate asset.
  • the loan can be offered at an initial loan rate of 100%, allowing individuals to fully leverage the equity of their fractional asset ownership.
  • the fractional real estate assets are far less volatile than other assets such as stocks and in contrast to regular personal home mortgages, the fractional real estate assets can produce dividends to partially offset, or even exceed, the interest payments, a possibility that is improved because of the diversified nature of the owned fractional asset.
  • the loan receiver and loan provider can both benefit from the expertise of a third party, such as a REIT management company, that directs and controls the complete real estate asset. In fact, if the real estate asset appreciates, the loan will no longer be 100% leveraged.
  • Embodiments of the invention also provide benefits to lenders by enabling the incorporation of recovery mechanisms for the fractional ownership in assets securing the loan. These recovery mechanisms may be smart-contracts stored on and executed by blocks on a blockchain that enable automatic collateral recovery in the case of loan default. This provides alternatives to the highly arduous and time consuming process of recovering a mortgaged property through, for example, a foreclosure process. Furthermore, by improving the ability of lenders to recover collateral, embodiments of the invention increase loan availability by decreasing the risk lenders take when they loan to higher risk borrowers. [0027] Principles of the present invention also leverage technology to improve efficiency.
  • Blockchains are a distributed ledger technology that allows for mutual verification, approval and sharing of transaction records among nodes distributed at multiple hubs on a computer network.
  • Blockchains allow for: (a) decentralized transactions not relying on a third party's trust (direct transactions between participants are possible), (b) the creation of resilient networks due to mutual data/system management, and (c) the prevention of tampering of recorded data (only new entries can be added by design, control over the recording of new data or records as new entries requires consensus among transaction parties, and fraudulent entries are rejected by parties).
  • Smart contracts are transaction conditions programmed and incorporated into blockchains that, when the predetermined contract conditions are met, the transaction is automatically performed.
  • FIG. 1 A is a schematic illustration of a blockchain 100 utilized by embodiments of the invention.
  • methods and systems embodying the present invention utilize blocks 101 of a blockchain 100 to store data, for example ownership records and asset value.
  • Embodiments of the invention may also allow that stored data to be viewed and verified by third parties, such as a loan distributor.
  • a blockchain 100 is a public, secure, distributed, cryptographically-proven ordered list.
  • Illustrated blockchain 100 is comprised of multiple blocks lOla-lOln (generally referenced 101 throughout this disclosure).
  • the first block 101a is known as the genesis block. After the genesis block 101a, each block refers back to the previous block (its predecessor block 101) in the chain. This is illustrated with arrows between the blocks 101.
  • block 101b refers back to block 101a and so on.
  • each block 101 may include a record of a transaction.
  • a block 100 may include records of one or more transactions. Some embodiments, may allow blocks 101 with zero transactions, e.g., to support timely delivery of new blocks.
  • the transactions may be transactions utilizing a cryptocurrency, for example a cryptocurrency backed by shares in a REIT, but this is not required.
  • a blockchain 100 can provide verification for a sequence of transactions.
  • Blockchain 100 is also provable. Using cryptography, it can be ensured that each block 101 is complete before the next block (its successor block 101) is initiated. For example, if the blockchain 100 is an ordered ledger with blocks 101 representing individual transactions, then the blockchain verifies that the transaction recorded by block 101b is completed before verifying that the transaction recorded by block 101c is completed. This is extremely useful in creating records for transactions that have cause and effects, e.g., a first user purchases a real estate asset, recorded in block 101b, and then the first or a second user pays for that real estate asset, recorded in block 101c. To accomplish this, blockchains 100 use cryptography to create proof that a block 101 is complete and is followed by its subsequent block.
  • each of the blocks 101 comprises a consensus proof, computed over one or more transactions.
  • the consensus proof is a cryptographic signature that establishes each block's completeness and location in the blockchain 100.
  • the consensus proof is created by using a cryptographic kernel that generates a public/private key pair.
  • Various equivalent Cryptographically Secured Distributed Ledger technologies may be used such as: Blockchain, Hashgraph, Directed Acyclic Graph, etc., as such technologies support the same concepts: consensus algorithms, cryptocurrencies, tokens, etc.
  • Blocks 101 may be stored on difference devices in different locations. However, these blocks are still connected in the blockchain 100 due to their cryptographic signature. Additionally, blocks 101 may be accessed and viewed from difference devices in different locations. This enables third parties not part of a transaction recorded on the blockchain to view and verify that the transaction has occurred. Additionally, because of the security provided by the block’s cryptographic signatures, the blockchain 100 and its component blocks 101 cannot be distrusted or altered. This enables the blockchain 100 and individual blocks 101 to be reliable and trustable records despite their distributed nature. Another level of security is added due to the public nature of blockchain 100 and its blocks 101. Since the blockchain is public, may copies of it and/or its component blocks can be created.
  • Blockchains provide the ability to track and settle balances and transactions for networks with thousands or even millions of geographically dispersed people who might not know, let alone trust, each other. Blockchains enables trustless transactions without the need for a centralized authority.
  • Embodiments of the invention utilize blockchains as part of a novel and unique approach to create verifiable records of the purchase and ownership of fractions of many different dispersed real estate assets.
  • Data memorializing the purchase and/or ownership of fractions of a real estate asset can be stored on one or multiple blockchain 100 blocks 101.
  • the payment for and transfer of these ownership fractions can also be stored on one or multiple blockchain 100 blocks 101.
  • the blocks 101 may be ordered to require the payment be completed before the ownership is transferred.
  • the blockchain 100 can be used by lenders to ensure that the loan requestor actually owns the fractional real estate asset to be used as collateral. This avoids the inefficient processes of relying on official government records as is done for mortgage underwriting and may even be impossible for dispersed fractional asset ownership.
  • the blockchain 100 and its component blocks 101 can serve as a proof of ownership that a lender and underwriter can rely on, due to the blockchain’s security features, to verify asset ownership.

Finally, if the value of the base is made public, either due to records stored on the blockchain 100 or in a more traditional manner, the lender will also be able to verify the value of the cryptocurrency tokens being offered as collateral.

Then the value of the total base is determined 205 based upon the value of its component distinct properties. This may be done automatically using the method of FIG 3 or similar algorithm that calculates the respective values of the distinct properties based on their intrinsic properties (characteristics) and/or market conditions. Other suitable h algorithms are known or common in the art.
  • cryptocurrency tokens can be minted 207 that represent ownership of a fraction of the base. If the base is a REIT, the cryptocurrency tokens minted at 207 can represent shares in the REIT. Each minted cryptocurrency token is backed by an initial amount of real estate. This may be done at a 1 : 1 ratio, for example if the base contains $1,000,000 worth of real estate across its component assets, one million cryptocurrency tokens can be minted so that at the time of minting, one cryptocurrency token is equal to 1 USD. Additionally, at minting, each token represents the same amount of percentage ownership in the base. For example, if 100 tokens are minted, each token represents a 1% ownership of the properties in the base.
  • Steps 203 through 207 may be repeated as new properties are added to the base. New cryptocurrency tokens may only be minted when new assets are added to the base. However, it is important to note that since the cryptocurrency tokens are fungible, they are not intrinsically tied to a specific property in the base but instead always represent a fractional ownership of the entire base. Each cryptocurrency token resulting from step 207 is a truly diversified fractional piece of the large amount of component real estate assets that comprise the base.

  • the algorithm may also utilize valuation information for properties in the base, or group of assets, as additional inputs for and/or validation metrics for the calculated valuation of other properties in the base, or group of assets. This selfreferencing ability, enables the algorithm to become increasingly accurate as the base grows and more properties are valued.
  • FIG. 3 is a flow chart of a method 300 for valuating properties within the property base utilized by embodiments, such as at step 205 of FIG 2, of the current invention.
  • Method 300 may be implemented as an algorithm (or processor routine) which when executed by a digital processor provides real-time valuation of the properties within the base.
  • information about the property is received 301. This information may be physical characteristics of the property, e.g. square footage, number of bedroom s/bathrooms, and nonphysical characteristics such as but not limited to purchase price, rental income, location, age.
  • the received information may be pre-processed in step 303 for example to identify missing, or bad data that can be corrected or excluded.
  • the method 300 may apply weights to the received information to increase or decrease the relevance of certain received information 301.

  • the method 300 may compare a property in a location with two bedrooms and one bathroom and 1000 square feet to the sale price, rental price, and valuation of other properties in that location, also with two bedrooms and one bathroom and approximately 1000 square feet. Based on this comparison, a valuation of the property can be calculated.
  • step 307 where the calculated valuation of step 305 is compared to internal data, such as the valuation of other properties in the group of assets. This comparison may be used to adjust the determined valuation based on market comparable.
  • step 309 the final valuation of the property is outputted. This may be displayed to a user through a user interface and/or be record on a block of a blockchain. Based on the final valuations, determined with method 300, of the properties in a group of assets, the total value of the group, and any fractional ownership thereof, can be calculated, recorded, outputted, and/or displayed.
  • One application of the invention disclosed herein is to enable loans using the cryptocurrency tokens, backed by fractional ownership of a collection of real estate assets, as an alternative to the traditional mortgage.
  • an individual instead of buying a complete real estate asset with a mortgage using that asset as loan collateral, an individual can purchase cryptocurrency tokens and use the purchased cryptocurrency tokens as loan collateral. Since the cryptocurrency tokens are backed by actual real estate assets in the base, they experience application the same way a regular real estate asset would. As the assets in the base appreciate and issue dividends, if that exceeds the interest on the loan, an owner of the cryptocurrency tokens builds equity even if they used those tokens, leveraged at 100%, as equity for a loan.
  • Embodiments of the invention may employ a user interface for purchasing tokens/shares (or other representations of fraction ownership) that may utilize a web3 interface connecting the user display to blockchain smart contracts.
  • This user interface can display the current conversion rates between the tokens or share equivalents implemented as smart contracts on the blockchain, using the automatically assessed valuation of the underlying real assets, and the fiat/digital currencies that can be used to purchase them.
  • a user uses the user interface to enter the desired quantity of tokens/shares to purchase and the currency being used to purchase them. In turn, the interface calculates the total price in the selected currency.
  • the user is redirected to a display that shows their existing balance of tokens/shares and any other currencies in their account, including the total value of all assets with the ability to select different units in which to express this total.
  • FIG. 4 is a flow chart of a method and system 400 employed in embodiments enabling or supporting a user to secure a loan based on fractional ownership of a group of real estate assets.
  • a user purchases 401 fractional ownership in a group of real estate assets, for non-limiting example a REIT. This purchase may be done using a web3 interface and/or executed with a smart contract on the blockchain 100 such as at step 209 of FIG 2.
  • the system and method 400 automatically creates 403 a verifiable record of ownership of the fractional real estate asset. This verifiable record may be stored on blockchain 100 in the distributed ledger 107 of nodes 105 such as at step 209 in FIG 2.
  • the verifiable record may be in the form of a cryptocurrency token, NFT, or shares.
  • a user may provide access 405 to a lender to that created record such as at step 211 in FIG 2.
  • the verifiable record can be stored on a blockchain 100 and supported by the value of the grouped real estate asset, a potential lender can trust that the user can support a requested loan.
  • the fractional ownership that record denotes is used as collateral 407 for a loan from the lender to the user.
  • This loan, and its terms may also be executed by smart contract and/or stored on blockchain 100.
  • the user has a loan underwritten by real estate assets, similar to that of a traditional mortgage but with greater diversification of risk and lower barrier to entry.
  • method 400 terminates at step 407.
  • loan interest and dividends in the fractional ownership may be automatically calculated 409 and applied to the user.
  • the user may then pay the set loan payments and receive their dividends 410.
  • the user may choose to use the dividends to pay off the interest and principle of the loans increasing the user's equity.
  • These calculations and payments may be done automatically using smart contracts and/or recorded on blockchain 100.
  • the ability to automatically create a distributed, verifiable, and accessible record of all steps of the loan process increases trust between the parties and decreases risk.
  • the lender may initiate automatic recovery 411 of the loan collateral and take ownership of the fractional assets. This recovery may be executed by a smart contract and/or automatically recorded on blockchain 100.

Abstract

Le système informatique et le procédé créent un enregistrement vérifiable de propriété d'actif et d'évaluation d'actif. Une chaîne de blocs stocke et maintient des données comprenant i) un enregistrement d'un actif sujet constitué de sous-actifs disparates et ii) des valeurs de l'actif sujet et des sous-actifs. Un premier registre immuable de la chaîne de blocs exécute en réponse l'achat d'une fraction de l'actif sujet et enregistre automatiquement la propriété de la fraction de l'actif sujet pour l'utilisateur acheteur. Un second registre immuable fournit un accès de visualisation à des tiers pour vérifier l'enregistrement de propriété par l'utilisateur acheteur.
