Balancing Caution and Opportunity in Underwriting

I have already examined key affordability measures like TDS, GDS, DCR, and LTI ratios. These metrics provide essential insights into a borrower’s financial capacity, but real-world underwriting requires more than just number-crunching. It’s about balancing caution with opportunity, finding a sustainable path for both lender and borrower.

When underwriting a loan, it’s crucial to remember that affordability measures are tools—not rules. They should guide decision-making, but not dictate it. For example, a borrower with a high GDS ratio might still be creditworthy if they demonstrate consistent income stability and low non-housing debt. Likewise, a strong DCR might not be sufficient if the borrower’s business operates in a volatile industry.

To make informed decisions, lenders should consider affordability measures in conjunction with qualitative factors, such as the borrower’s employment history, credit score, and asset base. Additionally, understanding the borrower’s broader financial context helps interpret the ratios correctly. For instance, high-income borrowers may sustain higher LTI ratios, while low-income borrowers may struggle even with lower ratios.

Lending policies should also account for economic shifts. In periods of rising interest rates or economic uncertainty, ratios that seemed reasonable a year ago may no longer apply. Proactive lenders will revisit their risk models and adjust ratio thresholds to reflect changing conditions, maintaining a balance between growth and risk management.

The goal is not just to approve or decline but to support sustainable credit. By layering affordability ratios with contextual analysis and ongoing risk assessment, lenders can foster long-term relationships while protecting their portfolios from undue risk. As the industry continues to evolve, maintaining this balance will remain fundamental to responsible credit granting
