We research from official program and regulatory sources before secondary commentary, and we link the primary source on the page. See our source library.
Where rules vary by state or county, we present ranges and direct readers to the authoritative local source rather than stating a single national figure, with a “confirm locally” note.
We do not make individualized eligibility determinations online, and we do not quote rates, payments, or savings.
Calculators provide educational estimates with stated assumptions. They are not a Loan Estimate, an offer, or a commitment to lend; actual terms are set by the lender and program.
