Your lender quotes 6.25% on a Friday. By Monday the same loan is pricing at 6.5%, and on a $400,000 VA mortgage that difference is roughly $65 a month for the next 30 years. A VA loan rate lock is the contract that decides who absorbs that swing: you or the lender.
Most borrowers grasp the basic idea. Fewer realize a lock is a bundle of conditions rather than a handshake. It has an expiration date, a list of things that void it, and a price that climbs with every extra week you ask for.
What a VA loan rate lock actually does
A rate lock freezes the interest rate and discount points on one specific loan scenario for a set period. It does not freeze your closing costs, your escrow deposit, or your APR. Those can still move between the lock date and the closing table.
Here’s something that catches people off guard: the VA doesn’t set lock rules. The department guarantees the loan against default; it doesn’t regulate how long a lender holds a rate. Lock periods, extension fees, and float-down terms come from the lender or the investor buying your loan, and they vary a lot from one company to the next.
What voids a lock
- Changing the loan amount beyond the lender’s tolerance, often 1%
- Switching loan structure, such as a VA fixed to a VA adjustable-rate mortgage
- Adding or removing a borrower from the application
- Changing the property, the occupancy type, or landing in a different loan-to-value tier after a low appraisal
- Letting the lock hit its expiration date without a paid extension
A small change doesn’t always kill the lock, but it can force a re-price at whatever the market is that day. Ask your loan officer for their exact tolerances before you get attached to a number.
How long should your VA rate lock run?
Standard windows are 30, 45, and 60 days, with 90-day and longer locks common on new construction. Price scales with length. As a rough guide from quotes circulating right now, a 30-day lock is usually baked into the base rate, a 45-day lock runs about 0.125 to 0.25 point, and 60 days costs 0.25 to 0.5 point. On a $350,000 loan, half a point is $1,750, real money that buys protection against a market move of roughly the same size.
The right length comes from your closing timeline, not your rate guess. VA purchase loans typically close in 30 to 45 days. Build in slack for the appraisal and notice of value, a termite inspection where the state requires one, and the occasional title issue that surfaces late.
Locking early versus locking late
Locking is insurance, and insurance has a premium. Lock 60 days out and rates fall half a point, you’re stuck at the higher number unless your lender offers a float-down. Wait too long and one hot inflation report can blow a hole in the budget you built around a payment.
If you want a read on direction, our breakdown of VA mortgage rate predictions for 2027 walks through where veteran borrowers could land and what pushes the number around. A forecast is not a lock substitute, but it helps you judge whether paying for 60 days of certainty is worth it.
Float-downs and what they really cost
A float-down lets you re-lock at a lower rate if the market drops after you lock. The typical structure is a one-time option triggered when rates fall 0.25% to 0.5% below your locked rate, priced at about 0.5 point or a slightly higher starting rate. Some are free but only available in the first 30 days of a 60-day lock.
Lock fees and points show up in the APR, which is why the APR on your Loan Estimate never quite equals the note rate. If the numbers on page one look off, our explanation of VA mortgage APR versus interest rate unpacks the gap.
When your lock expires before closing
It happens more often than it should. The appraisal runs late, the seller’s well inspection drags, the title company finds an old lien. Suddenly you’re 10 days from expiration with no clear-to-close.
Extensions are usually priced per 15 or 30 days. A common rate is 0.125% of the loan amount for 15 days, roughly $440 on a $350,000 loan, though some lenders charge a flat $250 to $500. If the lock actually lapses, many lenders re-price at the worse of your original rate or the current market.
Two protective moves: get a realistic closing estimate from your processor in writing before you lock, and find out the extension fee schedule before you need it.
Get the rate right before you lock it
A lock only protects the number you start with. Locking a mediocre quote for 60 days simply guarantees you’ll pay a mediocre rate for three decades.
Shop three or four VA lenders in the same week, ideally the same day, since pricing moves intraday. Compare the note rate, points, and the full lender fee stack rather than the headline rate alone. Our guide to spotting a bad VA quote before you lock covers the specific line items that separate a competitive offer from an expensive one. And if you want to push the number down first, these nine moves that actually shift VA mortgage rates are worth working through before you commit.
It also helps to know whether VA is even your cheapest option. Our side-by-side on VA mortgage rates versus conventional rates runs the math on both, including what happens once you factor in the funding fee and mortgage insurance.
Questions to ask before you sign the lock
- What is the exact expiration date and time?
- What does a 15-day or 30-day extension cost?
- Is there a float-down, and what triggers it?
- Which changes to my loan would force a re-price?
- Is the lock fee refundable if my purchase falls apart?
- Does the lock cover the rate, the points, or both?
- Does the lender or an investor hold the lock?
- What happens if my closing date moves up a week?
The 15-minute exercise that sets your lock length
Call your loan officer and ask three things: what closing date is realistic for your file, what a 30-, 45-, and 60-day lock costs on your scenario, and what the extension fee is. Count back from the closing date, then add 10 business days of buffer. That number is your lock length.
Now weigh it against the risk. If 15 extra days of protection costs 0.25 point, that’s $875 on a $350,000 loan. Would you pay $875 to remove the chance of a half-point rate increase right before closing? For a borrower with a firm move-out date and a fixed monthly budget, the answer is usually yes. For someone still touring houses with no accepted offer, locking now is premature and possibly expensive.
One more detail worth checking: a lock on a refinance works differently than a purchase lock, and many lenders cap cash-out refinance locks at 45 days. Ask which product your lock is written against, get the terms in writing, and keep the confirmation email somewhere you can find it in 40 days when the title company calls.
