A quote that lands well below everyone else's is a reason to dig in before you celebrate. A rate meaningfully better than prevailing quotes for a comparable conventional loan, at zero points, usually traces to one of a few things: conditions you haven't fully met yet (a specific credit score, a lower loan-to-value, a membership or relationship requirement, an occupancy or loan-size condition), fees that quietly offset the savings, or a headline number that won't be there when you go to lock. The check is straightforward. Get it in writing on a Loan Estimate and read the whole document, and only then the rate box. Confirm the points and lender credits on page 2, confirm the assumptions behind the pricing (score, loan-to-value, occupancy), and ask directly what has to be true for you to lock that rate. Then compare it against another lender's Loan Estimate for the identical loan, pulled the same day. Credit unions can genuinely offer sharp pricing, so this may be real and worth taking. A rate that stands out that far from the pack just deserves a line-by-line confirmation before you count on it. Send it over and we'll tell you straight whether it holds up or there's a catch.
