Editorial Methodology & Primary Sources

Verification date: Not recorded; check the primary source and lender timestamp before relying on an estimate.

Rate comparisons use participating lender feeds, not a whole-market survey or guaranteed offers. Freddie Mac PMMS is a market benchmark, not a personalized quote. Calculator models rely on published regulatory formulas and disclosed assumptions rather than fabricated first-person loan testing.

Monthly principal and interest use the amortization formula P × r / (1 − (1 + r)⁻ⁿ), where r is the monthly note rate and n is the number of payments; at zero interest use P / n. PITI adds monthly property taxes and homeowners insurance; PMI is separate. APR includes applicable finance charges under Regulation Z and is not the note rate used for payments. Compare lender Loan Estimates for actual APR and fees.

Consumer Financial Protection Bureau (CFPB) — Loan Estimates, APR and borrower disclosures; Regulation Z.
U.S. Department of Housing and Urban Development (HUD / FHA) — FHA program guidance.
U.S. Department of Veterans Affairs (VA) — VA loan eligibility and benefits.
Freddie Mac Primary Mortgage Market Survey (PMMS) — published rate benchmarks.
U.S. Census state tax collections — state property tax benchmarks; confirm parcel-specific assessments and exemptions with the state revenue department and local assessor.

The payment snapshot uses illustrative annual taxes of 1% of home price, $1,200 insurance and 0.5% PMI below 20% down, not verified local quotes. Other calculators disclose their inputs and assumptions. Published guidance and lender feeds may change independently; confirm current program rules, taxes and offers before a decision.
