In one aspect, the method may include determining a customer is approved for a mortgage (“mortgage ready”) and determining a real estate property is mortgage ready. The method may include comparing a calculated amount in which the customer is approved for a mortgage loan with a calculated appraisal value of the real estate property, and approving the mortgage application of the customer when the calculated amount the customer is approved for the mortgage loan is equal to, or exceeds, the calculated appraisal value of the real estate property, reducing a processing time and closing time of the mortgage. ## Claims ### Claim 1 A computer-implemented method comprising: maintaining a blockchain associated with a mortgage application of a customer, wherein maintaining the blockchain includes providing access to the blockchain to a plurality of authorized entities associated with the mortgage application; storing, on the blockchain, a first amount for which the customer is approved for a mortgage loan; after storing the first amount on the blockchain, monitoring the blockchain, using a trained machine-learned model, to determine updated information associated with the customer added to the blockchain by one or more of the authorized entities; determining, based at least in part on an output of the trained machine-learned model, an absence of an increased risk event associated with the customer; calculating, in response to determining the absence of the increased risk event and based at least in part on the updated information, an updated amount for which the customer is approved for the mortgage loan; compiling a new block for the blockchain including the updated amount, wherein compiling the new block includes computing a hash value associated with the new block, using a cryptographic hash function; and updating the blockchain to include the new block, wherein updating the blockchain includes cryptographically linking the new block to a previous block in the blockchain. ### Claim 2 (depends on 1) The computer-implemented method of claim 1, wherein the updated information includes one or more of customer age, marital status, homeowner status, income level, occupation, finances or income, insurance status, education level, employment status, telematics data, credit score data, deposit account data, or current payment stub data. ### Claim 3 (depends on 1) The computer-implemented method of claim 1, wherein the increased risk event is associated with one or more of a decrease in a deposit account, a declaration of bankruptcy, a decrease in credit score, an unemployment claim, or an age of a pay stub. ### Claim 4 (depends on 1) The computer-implemented method of claim 1, wherein the compiling the new block for the blockchain comprises adding the new block to a copy of the blockchain for validation by a remote computing source. ### Claim 5 (depends on 1) The computer-implemented method of claim 1, wherein the machine-learned model is trained based on training data including: a plurality of customer events; and a corresponding plurality of mortgage approval data associated with the customer events. ### Claim 6 (depends on 1) The computer-implemented method of claim 1, wherein the machine-learned model is further trained to predict a likelihood of a mortgage delay based on the updated information associated with the customer added to the blockchain. ### Claim 7 (depends on 1) The computer-implemented method of claim 1, further comprising: identifying a second blockchain associated with a plurality of real estate properties; and determining, from the second blockchain and based at least in part on the updated amount the customer is approved for the mortgage loan, one or more real estate properties of the plurality of real estate properties. ### Claim 8 (depends on 7) The computer-implemented method of claim 7, wherein the determining the one or more real estate properties comprises determining a subset of the plurality of real estate properties having an appraisal value equal to or below the updated amount the customer is approved for the mortgage loan. ### Claim 9 (depends on 8) The computer-implemented method of claim 8, further comprising: receiving a selection of a real estate property of the one or more real estate properties; and approving the mortgage loan associated with the customer and the real estate property. ### Claim 10 (depends on 9) The computer-implemented method of claim 9, further comprising: compiling a second new block for at least one of the blockchain or the second blockchain, the second new block including information about the mortgage loan. ### Claim 11 A computer system comprising: one or more processors; and a memory configured to store non-transitory computer executable instructions, the instructions being executed by the one or more processors to cause the system to perform actions comprising: maintaining a blockchain associated with a mortgage application of a customer, wherein maintaining the blockchain includes providing access to the blockchain to a plurality of authorized entities associated with the mortgage application; storing, on the blockchain, a first amount for which the customer is approved for a mortgage loan; after storing the first amount on the blockchain, monitoring the blockchain, using a trained machine-learned model, to determine updated information associated with the customer added to the blockchain by one or more of the authorized entities; determining, based at least in part on an output of the trained machine-learned model, an absence of an increased risk event associated with the customer; calculating, in response to determining the absence of the increased risk event and based at least in part on the updated information, an updated amount for which the customer is approved for the mortgage loan; compiling a new block for the blockchain including the updated amount, wherein compiling the new block includes computing a hash value associated with the new block, using a cryptographic hash function; and updating the blockchain to include the new block, wherein updating the blockchain includes cryptographically linking the new block to a previous block in the blockchain. ### Claim 12 (depends on 11) The computer system of claim 11, wherein the updated information includes one or more of customer age, marital status, homeowner status, income level, occupation, finances or income, insurance status, education level, employment status, telematics data, credit score data, deposit account data, or current payment stub data. ### Claim 13 (depends on 11) The computer system of claim 11, wherein the increased risk event is associated with one or more of a decrease in a deposit account, a declaration of bankruptcy, a decrease in credit score, an unemployment claim, or an age of a pay stub. ### Claim 14 (depends on 11) The computer system of claim 11, wherein the compiling the new block for the blockchain comprises adding the new block to a copy of the blockchain for validation by a remote computing source. ### Claim 15 (depends on 11) The computer system of claim 11, wherein the machine-learned model is trained based on training data including: a plurality of customer events; and a corresponding plurality of mortgage approval data associated with the customer events. ### Claim 16 (depends on 11) The computer system of claim 11, wherein the machine-learned model is further trained to predict a likelihood of a mortgage delay based on the updated information associated with the customer added to the blockchain. ### Claim 17 (depends on 11) The computer system of claim 11, the actions further comprising: identifying a second blockchain associated with a plurality of real estate properties; and determining, from the second blockchain and based at least in part on the updated amount the customer is approved for the mortgage loan, one or more real estate properties of the plurality of real estate properties. ### Claim 18 (depends on 17) The computer system of claim 17, wherein the determining the one or more real estate properties comprises determining a subset of the plurality of real estate properties having an appraisal value equal to or below the updated amount the customer is approved for the mortgage loan. ### Claim 19 (depends on 18) The computer system of claim 18, the actions further comprising: receiving a selection of a real estate property of the one or more real estate properties; and approving the mortgage loan associated with the customer and the real estate property. ### Claim 20 (depends on 19) The computer system of claim 19, the actions further comprising: compiling a second new block for at least one of the blockchain or the second blockchain, the second new block including information about the mortgage loan.
