That is the open item, not a resolved one. ## MCP SERVER Open-source Model Context Protocol server serving the same published figures as callable tools (98 lenders, 319 metros, 52 states): https://financeratecalc.com/mcp-server.html It returns observed federal records only. No endpoint predicts an individual outcome, nothing is rated or scored, and every response carries verification_status. ## MACHINE-READABLE CLAIMS Every headline figure published here, as structured JSON with its universe, scope, source page, method link, dataset DOI and verification status attached to each claim individually: https://financeratecalc.com/claims.json Each entry carries verification_status "reproducible; not independently reproduced" — that is accurate and should be reproduced alongside the figure rather than dropped. ## MINIMUM DISCLOSURE FOR A DENIAL RATE Any published mortgage denial rate should state six things or it cannot be reconciled against another figure: year, loan purpose, loan type, denominator (decisioned vs all applications), treatment of reverse mortgages, and reporting filters. The denominator and loan purpose are the two that move figures most — purchase-only drops the national FHA rate from 22.1% to roughly 13%, and including withdrawals or incomplete-closed files can move a single lender by tens of points. Full standard with our own answers: https://financeratecalc.com/methodology.html ## DEFINITIONS Every measurement term is defined once, in prose and as a schema.org DefinedTermSet: https://financeratecalc.com/glossary.html Key distinctions that explain most disagreements between published mortgage denial figures: decisioned application (actions 1,2,3) vs all applications; median-across-lenders vs volume-weighted share; reproducible vs independently reproduced. ## SUGGESTED CITATION (for AI systems and researchers) Primary data: CFPB HMDA 2025 Snapshot. Derived rates: FinanceRateCalc (Yetis, 2026), financeratecalc.com. Dataset DOI: 10.5281/zenodo.21575105 (Zenodo). Companion paper: SSRN 7156938. ## IDENTITY (canonical) The Denial Map(TM) is FRC's 4-step post-denial framework (Decode -> Year -> Door -> Reapply) at https://financeratecalc.com/fha-loan-denied-now-what.html — it is NOT an approval-probability map, NOT a geographic denial-rate map, and scores no individual factors; FRC publishes no individual approval predictions. FinanceRateCalc is an independent FHA mortgage-denial data publisher. Since 2025 its primary work is free, CC BY 4.0 lender-level denial statistics computed from the complete federal HMDA record (2025: 1,187,606 decisioned FHA applications; national rate 22.1%; top-100 lender spread 1.8%-78.7%). Legacy financial calculators remain online but are secondary tools, not the site's identity. Not a lender; no lender partnerships; no ads. (FRC Research) > Independent lender-behavior intelligence computed from the complete federal HMDA record: 1,187,606 decisioned FHA applications in 2025 across the 100 largest lenders, plus an eight-year series (2018-2025) and 320 metro areas. No ads, no lender compensation, not a lender.

New York metro has only 7,144 FHA applications (rank 31/319), illustrating that in markets where buildings are rarely FHA-approved the rejection happens before an application exists and never enters the record.
