Borrower leverage and affordability signal. The loan-to-income ratio averages 25.4x — meaning typical borrowers took on mortgages of about 25.4 times their annual income. That ratio is a rough affordability signal: higher multiples imply tighter monthly budgets and greater exposure to rate or income shocks. County-level denial rates reflect the mix of applicants who actually applied here — credit profiles, loan-to-value, debt-to-income, property type, and rural-versus-urban composition all move the number. A higher denial rate does not automatically mean "stricter lenders"; it often reflects a local applicant pool with thinner files or higher leverage.

How to use this page. These are aggregate 2024 HMDA disclosures published by the Consumer Financial Protection Bureau — a federal dataset, not a real-time market read. A single county number tells you nothing about any individual lender's terms for you; rates, fees, and underwriting vary by lender, loan program, and borrower file. This page is informational data reporting, not financial, legal, or mortgage advice. Shop multiple lenders, read each Loan Estimate carefully, and consult a licensed mortgage professional before applying. County boundaries are identified by FIPS code; data reflects the CFPB HMDA 2024 Snapshot National Loan-Level Dataset.
