Documenting decision rationale in an affordability check creates a traceable record of how the borrower’s finances were evaluated. This is essential for audit and compliance because it shows that the lender followed policy, used appropriate data, and considered all required factors. It also supports future approvals: if the file is reviewed later or handed to another underwriter, the reasoning is clear, making it easier to justify the decision or re‑evaluate it if circumstances change. The other ideas—sharing only with customers, automatically speeding up underwriting, or using the rationale to determine the final interest rate—don’t capture the main value of this documentation. The rate is driven by policy and risk factors, while the rationale serves governance, accountability, and defensibility of the lending decision.
