Who measures, and why

A denial is a data point, not a verdict on you. Someone had to start measuring it that way.

FinanceRateCalc is an independent research institution built and run by one person: Ziya Yetiş, an independent researcher. The premise is simple: every FHA credit decision in the public federal record (1.2 million in 2025) can be computed into statistics that borrowers, journalists, and researchers can actually use — so someone should do it, openly.

What we publish

The Denial Map — what to do after a denial. The Door Effect — how much of a denial is the lender, not the file. The Mortgage AI Accuracy Index — an independent benchmark of what AI systems tell consumers about mortgage denial. The Evidence Base — the tables behind all of it. Weekly findings ship in The Denial Dispatch.

How we work

Independence. No lender, AI vendor, or data broker funds, reviews, or previews this work. Revenue comes from readers and professional subscribers, never from the institutions being measured.

Method before message. Every figure has a stated denominator rule, a minimum cell size (n≥100), and open data behind it (CC BY 4.0, link back). Corrections are published, not silently patched — including corrections to our own scoring.

The red line. We describe markets and history. We never predict an individual's approval odds, and no page on this site ever will.
