30 year home interest rates: last-mile checklist

I'm at the point of choosing, not browsing. Rates can shift before dinner; I locked during a lunch break after a lender rate-sheet ping, then double-checked. At first I trusted one quote - wait, one day's quote - but I tightened the proof.

Step-by-step control

1. Pull current mortgage rates from three sources; timestamp and average.
2. Separate APR vs interest rate to surface fees and points.
3. Pick a fixed-rate mortgage unless your timeline is short; document why if not.
4. Call two brokers and one bank to compare lenders on the identical scenario.
5. Test 30-year mortgage refinance rates in a what-if; lock only if a 0.25% bump still pencils.

Final call

Proof wins, control holds: I lock when the math, timeline, and documents align - no surprises, just terms I can defend.
