Locked vs. Floating Mortgage Rate Quotes: 5 Questions to Ask Before You Compare Lenders

If you are shopping lenders, one of the fastest ways to get misled is to compare a locked quote against a floating quote and assume you are looking at a real price gap.

Sometimes you are. A lot of times, you are really seeing a commitment gap. One lender is showing pricing that is protected for a defined lock window, while the other is showing whatever the market looked like at that exact moment with no guarantee it will still be there tomorrow.

That does not make floating quotes dishonest. It does mean they need to be labeled correctly before you decide who is actually cheaper.

The short answer: locked and floating are not interchangeable

A floating quote is a snapshot. A locked quote is a commitment with conditions, timing, and usually a specific lock period behind it.

If lender A is floating at 6.625% with lower points and lender B is locked at 6.75% with a 30-day lock, that does not automatically mean lender A is better. It means lender A is still exposing you to market movement while lender B is already holding pricing in place.

5 questions to ask before you compare two mortgage quotes

1. Is each quote locked or floating? Ask this first. If the answer is not clearly labeled, you do not have a clean comparison yet.
2. What lock term is being assumed? A 15-day, 30-day, and 45-day lock can price differently. A quote can look better simply because the lock window is shorter.
3. How many points or lender credits are built in? Two lenders can show the same note rate with very different upfront cost. You need to know whether you are buying the rate down or taking credit.
4. Does the monthly payment use realistic taxes, insurance, and mortgage-insurance assumptions? A light escrow estimate can make one quote look cleaner than it really is.
5. What is actually driving cash to close? If one option needs more cash, ask whether the difference is points, escrows, prepaid interest, or fees. That tells you whether the quote is more expensive or simply structured differently.

Where borrowers get tripped up

Most borrowers do not get in trouble because they failed to ask about rates. They get in trouble because they compared numbers that were built on different assumptions and then treated them like final offers.

The most common issues are simple: one quote is floating, one is locked, one uses cheaper insurance, one shows optimistic taxes, or one is loading points in a way that never got explained clearly.

When a floating quote is still useful

A floating quote can still be useful early in the process. It helps you understand where pricing is today and whether a lender is even in the right range.

Just do not confuse a floating quote with a final decision tool. If you are close to writing an offer, under contract, or trying to decide whether to lock, you need more than a soft snapshot.

What to ask your lender in plain English

• Is this quote locked today or still floating?
• If it is locked, how many days does the lock cover?
• How many points or credits are included?
• Are the taxes and insurance based on this actual property?
• If I waited until tomorrow, what part of this quote could change?

If your lender cannot answer those cleanly, the quote is not ready to compare with confidence.

My rule for quote shopping

If you are serious enough to choose a lender, you are serious enough to force an apples-to-apples comparison. That means same day, same lock status when possible, clear points or credits, and a payment built on believable assumptions.

The goal is not to chase the flashiest rate on a text message. The goal is to understand what you are actually buying.

What to do next

If you already have a Loan Estimate or lender worksheet, you do not need to guess whether the comparison is clean. You have enough to pressure-test it.

This is where a second opinion helps most: before you lock the wrong quote, before you overpay for points you did not mean to buy, and before you mistake a floating teaser for a committed offer.
