Sources: Direct published lender pages for named bank and credit-union examples; live lender-market percentiles and coverage via LoanGlass's public mortgage-rates MCP service; Freddie Mac PMMS via FRED; and the 10-Year Treasury via FRED DGS10.
Live vs modeled: Direct lender examples and LoanGlass observations are shown first. MFA's modeled histogram appears only when a live lender-market distribution is unavailable.
Not advice: MFA is educational. National averages and community quotes are context, not an offer or a rate you will receive. Your rate depends on credit, down payment, loan type, points, property, lender pricing and underwriting. Use MFA's mortgage calculators with a real lender quote before deciding.
