🔒 The Reality: Rate Locks Last 15-60 Days
A mortgage rate lock guarantees your interest rate for a set period (typically 15-60 days). Once locked, your rate won't change even if market rates rise. But if rates fall, you're stuck with your locked rate. Lock too early = risk rates dropping. Lock too late = risk rates rising.
Key Stat: 67% of borrowers lock rates between day 3-7 of application. Average lock period: 30 days. Extension costs: $200-500 per 15 days.
