Applying for a fixed rate doesn’t automatically guarantee that rate until settlement. Some lenders offer a separate rate-lock feature, usually for a fee, for a defined period, that protects your quoted fixed rate from rising before settlement. Without it, the rate you were quoted at application can simply move.
What can happen to an unlocked fixed rate
A fixed rate you’re quoted at application is often not guaranteed until settlement, if rates move before your loan settles, some lenders will apply the new, higher rate instead of the one you were originally quoted. Rate lock is designed to close that exact gap by fixing the rate itself from the point of the lock, not just from settlement.
What genuinely varies by lender
- When rate lock can be requested during the application process
- How long the lock lasts
- Whether there’s a fee, and whether it’s refundable depending on the outcome
- Whether you still benefit if the fixed rate actually falls before settlement, or whether you’re locked into the higher figure either way
- What loan changes (amount, product, settlement date) can invalidate the lock
- Whether construction/progress-draw lending is eligible at all, some lenders explicitly exclude it
No average fee, on purpose
Rate-lock fee structures differ meaningfully between lenders, some charge a flat dollar amount, others a percentage of the loan amount, and refundability terms vary too. PolicyMatch does not publish an “average rate-lock fee,” because lender structures differ too much for that figure to mean anything useful. Ask your lender directly for their current rate-lock terms before relying on one.
What to prepare
- Ask specifically about rate lock, not just “can I fix”, they’re different questions
- Get the fee, lock period and refund terms in writing
- Check eligibility if your loan involves construction or progress draws
