Can You Lock a Mortgage Rate Before Making an Offer? 2025 Guide

Quick Answer: Yes, you can lock a mortgage rate before making an offer, but it's usually not recommended. Most buyers should wait until their offer is accepted, then lock immediately. Locking too early wastes your lock period and could cost you money if rates drop.

One of the most confusing questions in the home buying process is: "When should I lock my mortgage rate?" Lock too early and you might waste your lock period. Lock too late and rates could spike, costing you thousands.

The timing of your rate lock is critical. A rate lock that expires before closing could force you to accept a higher rate or pay to extend the lock. On the flip side, locking too early when rates are volatile could mean missing out on better rates.

🔒 What is a Mortgage Rate Lock?

Simple Definition

A rate lock is a lender's promise to hold a specific interest rate for a set period of time (usually 30-60 days).

During the lock period, even if market rates rise, your rate stays the same. However, if rates fall, you typically cannot benefit from the lower rate (unless you have a "float down" option).

Cost: Rate locks are typically free, but some lenders charge 0.25-0.5% to lock in a rate.

✅ Benefits of Rate Lock

  • Protection if rates rise
  • Peace of mind during home search
  • Accurate budget for your offer
  • Competitive advantage in offers

❌ Risks of Rate Lock

  • Lock expires before closing
  • Miss lower rates if market drops
  • Extension fees if lock expires
  • Wasted lock period if offer rejected

📅 The Home Buying Timeline & Rate Lock

Week 1: Get Pre-Approved (Don't Lock Yet)

What happens: You apply for a mortgage and get pre-approved with a rate quote

Rate lock decision: Most lenders give you a "soft quote" for 5-7 days. Don't lock yet – you might not find a home.

Week 2-3: Find Home & Make Offer

What happens: You find a home and submit an offer

Rate lock decision: Still don't lock. Your offer might be rejected.

Week 4: Offer Accepted ✅ LOCK NOW

What happens: Your offer is accepted. Now you're committed to buying.

Rate lock decision: THIS IS THE TIME TO LOCK. Get a 45-60 day lock to cover appraisal, underwriting, and closing.

Week 5-7: Appraisal & Underwriting

What happens: Lender appraises property and reviews your finances

Rate lock decision: Your lock is active. Monitor it – if it expires before closing, you'll need to extend.

Week 8-9: Clear to Close & Closing

What happens: Final walkthrough, sign documents, get keys

Rate lock decision: Your rate is locked in. Closing happens within your lock period.

Lock your rate AFTER your offer is accepted, not before.

1. Get Pre-Approved First (Don't Lock)

2. Lock After Offer Accepted

Once your offer is accepted in writing, immediately ask your lender to lock your rate.

3. Get a 45-60 Day Lock

Most closings take 30-45 days. Get a 45-60 day lock to have a buffer.

4. Ask About Float-Down Options

Some lenders offer "float down" – if rates drop, you can lock the lower rate. Ask about this!

5. Confirm Lock in Writing

Get written confirmation of your lock period, rate, and any extension costs.

6. Monitor Your Lock Expiration

Mark your calendar. If closing is delayed, contact your lender immediately about extending.
