Predictive Model for Equity Release Profitability and LTV Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current financial products, such as reverse mortgages, lack effective tools for evaluating profitability and loan characteristics, particularly in terms of loan-to-value ratios, borrower age, and geographic market considerations, which hinders lenders' ability to manage risk and optimize profitability.
Innovation Solution
A modeling technique that creates representative loans and scenarios, including joint interest rate and house price scenarios, to evaluate equity release products, determining profitability metrics and LTV ratios, facilitated by a computer system executing appropriate software instructions, allowing for the aggregation of profitability metrics across various scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional reverse mortgage products are used without predictive modeling, then the underwriting process is simple and quick, but the ability to evaluate profitability and manage risk is insufficient
Solution Approach 1:
The patent applies preliminary action by creating representative loans and scenarios before actual lending decisions are made. The system pre-establishes multiple loan scenarios with different characteristics (borrower types, mortality tables, interest rates, house prices) and runs them through predictive models to evaluate profitability metrics and determine optimal LTV ratios in advance, enabling better risk management before actual loans are issued
Solution Approach 2:
The patent uses copying by creating virtual representative loans that replicate real loan characteristics without actual financial exposure. These simulated loans copy the essential features of real reverse mortgages (borrower demographics, property characteristics, loan terms) allowing the system to analyze profitability and risk across multiple scenarios without committing actual capital
2Measurement precision
If multiple loan scenarios are created to evaluate profitability, then the accuracy of profitability metrics improves, but the time required for analysis increases
Solution Approach 1:
The patent applies segmentation by dividing the loan portfolio into distinct representative loan categories (different borrower types, age groups, geographic markets) and analyzing each segment separately through multiple scenarios. This allows the system to handle complexity by breaking down the overall analysis into manageable segments while maintaining comprehensive coverage of all loan characteristics
Solution Approach 2:
The patent uses parameter changes by systematically varying key loan parameters across multiple scenarios (interest rates, house prices, borrower ages, LTV ratios) to observe their impact on profitability metrics. By changing these parameters across different simulated loans, the system identifies optimal parameter combinations that maximize profitability while managing risk
3Productivity
If LTV ratio is increased to maximize loan amount, then the loan volume increases, but the risk of non-recourse loan losses increases
Solution Approach 1:
The patent applies feedback by using predictive models to continuously evaluate the relationship between LTV ratios and profitability metrics across multiple scenarios. The system analyzes the outcomes of different LTV levels and provides feedback on which ratios optimize profitability while controlling risk, allowing the system to dynamically determine optimal LTV ratios rather than using fixed high ratios
Solution Approach 2:
The patent uses parameter changes by systematically varying LTV ratios across different loan scenarios and observing their impact on both loan volume and profitability metrics. By changing the LTV parameter across multiple simulated loans with different characteristics, the system identifies the optimal LTV ratio that maximizes productivity while minimizing harmful factors like non-recourse losses

AI summary
A predictive model for use in providing an equity release (reverse mortgage) financial product is disclosed. In at least some embodiments, a plurality of representative loans are created, wherein each loan can be characterized by a borrower type and a mortality table. A plurality of joint interest rate and house price scenarios are also created. Each of the representative loans can be run through each of the joint interest rate and house price scenarios to measure profitability metrics. The model can also be used to determine loan-to-value (LTV) ratios based on considerations including borrower age, loan volume sensitivity, a determined profit-maximizing LTV ratio, and geographic market considerations.
