Buying a Home
Should I Lock My Mortgage Rate Now? An Atlanta Buyer’s Guide
Under contract on an Atlanta home and unsure whether to lock your mortgage rate or float? Here is how a rate lock works, what it costs, and how to decide.
Quick answer
If you’re under contract on an Atlanta home and the payment works for you at today’s rate, I would lean toward locking rather than floating. Freddie Mac’s 30 year fixed average was 7.32% for the week of October 22, 2026, down from 7.40% two weeks earlier but up from 6.19% a year before, so rates have moved in both directions recently. A lock protects your payment through a typical 30 to 45 day Georgia closing, and if rates fall later you may be able to use a float down option or refinance.

What a rate lock actually does
A rate lock is your lender’s commitment to hold a specific interest rate and points for a set number of days while your loan is processed. If rates rise during that window, your rate doesn’t. If rates fall, a standard lock also doesn’t move, unless your lender offers a float down option.
A few details matter more than people expect:
- Most lenders lock once you have a property under contract. Before that, you can see quotes, but you usually can’t lock a rate on a home you haven’t chosen yet.
- Locks come in lengths, often 30, 45, or 60 days. Longer locks may cost more, either as a slightly higher rate or a fee, because the lender is holding the price longer.
- The lock has to cover your closing date. If closing slips past the lock’s expiration, an extension usually costs money, and if the lock lapses you may get whatever the market rate is that day.
- Your Loan Estimate shows lock status. Page one says whether your rate is locked and until what date and time. If it says no, your rate can still change.
Lock or float: how I would think about it
Floating means you wait to lock, hoping rates fall before closing. Nobody can tell you where rates will be in three weeks, including your lender, so I would make the decision based on your budget, not a forecast.
Here is what I tell buyers who ask:
- Run your payment at today’s rate. If the monthly number already works comfortably, locking removes the risk of a jump you can’t absorb.
- Run it again a quarter point higher. On a $400,000 loan, a quarter point on a 30 year fixed changes the principal and interest payment by roughly $68 a month at today’s rates. If that higher number would break your budget, floating is a bet you can’t afford to lose.
- Ask what the lock costs at your closing length. If a 45 day lock costs little more than a 30 day lock, the extra cushion is often worth it.
- Ask about a float down. Some lenders let you take a lower rate once if the market drops by a set amount before closing, sometimes for a fee. It isn’t free, and the terms vary a lot, so get them in writing.
If you float, set a deadline. I would pick a date, often a week or so before closing, when you lock no matter what, so the decision doesn’t keep moving.
Why Georgia timelines matter for your lock
A financed Georgia closing usually takes 30 to 45 days from the binding agreement date, and the closing attorney, the appraiser, and the lender all have to finish their part inside that window. I see closings slip for ordinary reasons: a low appraisal that needs renegotiating, an underwriting condition, or a title issue the attorney has to clear.
Because of that, I would choose a lock that runs a little past your contract’s closing date rather than one that expires on it. It costs less to buy a few extra days up front than to extend a lock under pressure the week of closing.
If you’re buying while selling your current home, or your closing is set further out than usual, talk to your lender before you sign the contract about how long they can lock and what a longer lock would cost.
Ways to get a lower rate besides waiting
If today’s rate makes the payment uncomfortable, waiting isn’t the only option. A few I walk buyers through:
- A seller paid buydown. With more homes on the market, some sellers will put money toward lowering your rate, either for the first few years or for the life of the loan. My guide to seller paid rate buydowns shows how they work.
- An assumable loan. Some FHA and VA loans can be taken over at the seller’s original rate. They take longer and need more cash, but in a 7% market they are worth checking. See how assumable mortgages work in Atlanta.
- A different loan type. An adjustable rate mortgage may start lower than a 30 year fixed. It carries real risk later, which I lay out in ARM or fixed rate for Atlanta buyers.
- Points. Paying discount points at closing lowers the rate in exchange for cash up front. Ask your lender how many months it would take for the lower payment to pay back the cost.
Which of these fits depends on the home, the seller’s situation, and how long you plan to stay, and that is where it helps to have someone negotiating the offer with the rate in mind, not just the price.
Questions to ask your lender before you lock
Before you lock, I would get answers to these in writing, ideally in an email you can forward to your agent:
- What rate and points am I locking, and what is the exact expiration date and time?
- What does an extension cost per day or per week if closing slips?
- Is there a float down option, what does it cost, and how far do rates have to fall to use it?
- Will anything in my file change the locked price, such as a lower appraisal, a change in my credit score, or a change in my down payment?
- If I am buying new construction with a long build time, what is the longest lock you offer and what does it cost?
That last question matters more than people expect. On a new build with a closing several months out, a standard lock won’t reach, and you’ll want to know your options before you sign the builder’s contract. Builders often advertise rate incentives tied to their affiliated lender, and you’re free to compare those offers with any other lender you choose.
What the numbers say right now
According to Freddie Mac’s weekly survey, the 30 year fixed averaged 7.40% for the week of October 8, 2026 and 7.32% for the week of October 22. The 15 year fixed averaged 6.68% on October 22, down from 6.71% the week before. A year earlier, the 30 year average was 6.19%.
On the housing side, Georgia MLS reported 3,436 pending sales in its 12 county Atlanta area in September 2026, down 24.8% from a year earlier, with 23,006 active listings, up 5.3%. Fewer buyers under contract and more homes for sale means more room to negotiate on price and credits, which can matter as much as a quarter point on the rate.
Rate lock FAQs
Usually not. Most lenders lock once you have a signed purchase contract, because the lock is tied to a specific property and closing date. Some lenders offer longer locks for buyers still shopping or building, often at a higher cost.
You can usually pay to extend it, or the lender may reprice your loan at the current market rate. If rates have risen, that could raise your payment. Choosing a lock that runs past your scheduled closing date helps avoid this.
Yes, but the lock stays with the original lender. Switching means starting a new application and a new lock, which can put your closing date at risk in a 30 to 45 day Georgia contract.
Many lenders include a standard lock at no separate charge, while longer locks or float down options may cost more. Ask for the cost in writing and check the lock date on your Loan Estimate.
Possibly. A refinance has its own closing costs, so it tends to make sense only when the drop is large enough to pay those costs back in a reasonable time. Your lender can run that break even for you.
Next steps
The lock decision is really a budget decision: if the payment works today, protecting it through closing is usually the safer choice. If you’re getting ready to buy and want to know which neighborhoods fit your payment at today’s rates, book a consultation with me and we can map it out before you start touring.
