A rate lock freezes your mortgage interest rate for a set period — typically 30, 45, or 60 days — protecting you from market fluctuations while your home purchase is being finalized.
But when exactly should you lock? Timing matters.
1. The rate fits your financial plan Don't chase the absolute lowest rate. What matters most is whether your monthly payment is comfortable and sustainable for your long-term budget.
2. Your loan application is nearly complete Once you're under contract and your lender has most of your documents, locking makes sense. You'll typically be entering escrow at this stage.
3. Market signals suggest rates are rising If economic indicators, Federal Reserve announcements, or your lender's guidance suggest rates will climb, locking early can save you thousands over the life of your loan.
Some lenders offer a float-down option that lets you renegotiate if rates decrease significantly. Ask your lender about this before locking.
It's nearly impossible to time the absolute bottom of interest rates. Focus on a rate that works for your budget — not on catching the perfect moment.
