Rate is a points-normalized estimate (each loan adjusted toward its zero-point equivalent using a standard ~0.25%/point buydown assumption), shown alongside typical closing costs so rate and cost are weighed together — a lower rate often comes with higher points or fees. From crowdsourced and public HMDA data, for comparison only. Not an offer, quote, or savings estimate.
