Automated Underwriting Engine for Mortgage Risk Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating mortgage loan risk characteristics are not accurate enough, particularly for investors in the secondary mortgage market, as they do not adequately account for specific risks and costs associated with individual investors, leading to potential defaults and delinquencies.
Innovation Solution
An automated underwriting engine calculates two risk indications: a first risk indication based on interest rate and collateral risks, and a second risk indication representing the probability of adverse events, providing actionable recommendations for lenders and risk management tools for investors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional single risk indication methods are used for loan evaluation, then the evaluation process is simple, but the accuracy of risk assessment is insufficient
Solution Approach 1:
The patent segments the risk assessment into multiple independent components: a first risk indication based on investor-specific parameters (interest rate risk, collateral risk) and a second risk indication based on borrower-specific parameters (credit score, debt-to-income ratio). This segmentation allows each component to be calculated and weighted separately, improving overall assessment accuracy while maintaining manageable system complexity through modular design.
2Adaptability or versatility
If investor-specific risks are not accounted for in loan evaluation, then the evaluation process is faster, but the relevance to individual investors is reduced
Solution Approach 1:
The system performs preliminary calculations of the first risk indication (investor-specific risks) and second risk indication (borrower-specific risks) separately before combining them. This preliminary action allows investor-specific parameters to be pre-calculated and stored, enabling faster retrieval and combination during actual loan evaluation, thus maintaining productivity while enhancing adaptability to different investors.
3Measurement precision
If multiple risk indications are calculated and combined, then the risk assessment accuracy improves, but the computational complexity increases
Solution Approach 1:
The patent transforms multiple risk indicators into a standardized format by calculating weighted combinations where each risk factor is assigned a specific weight. The first risk indication uses weights for interest rate risk and collateral risk, while the second uses weights for credit score and debt-to-income ratio. This parameter transformation approach allows accurate multi-factor assessment while controlling computational complexity through systematic weighting rather than complex interactions.

AI summary
A system for evaluating risk associated with a mortgage loan includes an automated underwriting engine configured to calculate a first risk indication and a second risk indication for the mortgage loan. The first risk indication is based on mortgage loan application data received for the mortgage loan, and further based on at least one of interest rate risk and collateral risk associated with the mortgage loan. The second risk indication represents a probability of an adverse event associated with the mortgage loan. The probability of the adverse event is determined based on the mortgage loan application data. The system also includes user interface logic configure to provide a user interface, and further configured to provide the first risk indication to a lender in the form of an underwriting recommendation for the mortgage loan, and to provide the second risk indication to the lender in a form which is useable by the lender to manage the risk associated with the mortgage loan.
