If you are under contract, yes, lock. The 30-year fixed has risen seven weeks in a row to 7.40 percent, and the cost of locking into a rate that later falls is far smaller than the cost of floating into one that keeps climbing. If you are not under contract yet, there is nothing to lock, and the useful move is a different one.
We are getting this question several times a week right now, and the emotion behind it is usually the same: the buyer feels like they already missed something. Rates sat still all summer, and then they did not. That feeling is understandable but it is a bad basis for the decision, because the lock question is not really a forecast question. It is a risk question with very lopsided consequences.
What the rate has actually done since August
Freddie Mac’s Primary Mortgage Market Survey is the weekly benchmark, published every Thursday. Here is the run.
- 30-year fixed, week ending October 8, 2026: 7.40 percent Freddie Mac PMMS, October 8, 2026
- October 1: 7.28 percent. September 24: 7.03 percent. September 17: 6.95 percent Freddie Mac PMMS, September and October 2026
- August 20: 6.65 percent, the bottom of the summer plateau Freddie Mac PMMS, August 20, 2026
- A year ago, week ending October 9, 2025: 6.30 percent Freddie Mac PMMS, October 9, 2025
- 15-year fixed, week ending October 8, 2026: 6.73 percent Freddie Mac PMMS, October 8, 2026
That is 75 basis points in seven weeks, every single week in the same direction. Put it on a real Wilmington payment. The three-month median sale price in New Hanover County is $448,000 (Redfin, August 2026). With 20 percent down that is a $358,400 loan. Principal and interest at 7.40 percent is $2,481 a month. At the 6.65 percent of August 20 it was $2,301. The same house now costs $181 more a month, or about $2,168 a year, than it did at the end of the summer.
Said the other way, which is the version that matters if you are shopping rather than closing: the payment that bought a $358,400 loan in August buys about $332,300 today. Roughly $26,000 less house for the same monthly number.
What a lock costs you if you are wrong
Here is the asymmetry that makes this decision simpler than it feels.
If you lock and rates fall, you are stuck with a rate you agreed to, and you can refinance later at whatever it costs to refinance. Annoying, recoverable.
If you float and rates rise, two things happen at once. Your payment goes up, and your approval can shrink. A quarter point on that $358,400 loan is about $61 a month. That sounds survivable until you remember that your lender re-ran your debt-to-income at a specific rate, and a buyer who was approved with no margin can fall out of qualification entirely. We have had that happen to a buyer in this market inside a single week. It is a far worse outcome than paying a slightly above-market rate.
Both of those are knowable in advance. Where rates go next is not. So we tell our buyers to decide this the way you would decide on any other insurance: by what you can afford to be wrong about.
The three questions that actually decide it
When do you close?
A standard lock runs 30 to 60 days. If your closing is inside that window, lock now. If it is 90 days out, ask what a longer lock costs rather than assuming you cannot have one. Lenders price extended locks, and the fee is usually a fraction of what another 40 basis points would cost you.
Does the lock have a float-down?
Some lenders will let you capture a lower rate once if the market moves materially in your favor before closing, usually for a fee or a slightly higher starting rate. In a stretch like this one, that option is worth asking about by name. Most buyers never do, because nobody offers it unprompted.
What happens if you need an extension?
Lock extensions cost money and they are the single most common unpleasant surprise in a delayed closing. On new construction this is the one to pin down first. A 60-day lock on a house the builder expects to deliver in 90 is a problem you are scheduling for yourself. We wrote about delivery timing in what happens if your new construction home is delivered late.
New construction changes the math
If you are looking at a new home in Leland, Hampstead or the Brunswick 17 corridor, the rate on the screen may not be the rate you pay. Builders in this market are funding rate buydowns into the 4s and five-figure closing credits rather than cutting list price, and we are tracking roughly $20,000 in current incentives on select homes this month across the six builders on our new construction pages (Tidal Realty Partners, October 2026). A builder-funded buydown is money somebody else is spending, which makes it almost always the better deal than points you pay yourself. We compared the two in detail in points or a rate buydown.
The catch is that those incentives usually require the builder’s preferred lender, which is a trade worth examining rather than accepting. Our view on that is here.
Nobody knows where rates go next, including us, and anyone who tells you otherwise is selling something. The Federal Reserve meets October 27 and 28 and again December 8 and 9 this year (Federal Reserve FOMC calendar, 2026), and buyers routinely assume a Fed cut means a lower mortgage rate. It does not work that way. The 30-year fixed tracks the bond market’s view of inflation and growth, and it has moved up on days the Fed cut before. The other honest note: our own monthly mortgage update is refreshed monthly and still carries the September 17 reading of 6.95 percent, so if you landed here from that page, the 7.40 percent figure above is the current one. And if you are not under contract, none of this applies yet. What helps at that stage is a pre-approval that has been stress-tested at a rate above today’s, so that a bad week does not take your house away from you.
Related questions people also ask
Can I lock a mortgage rate before I have a house under contract?
Generally no. Most lenders require a property address and an executed contract before they will issue a lock, because the lock is tied to a specific loan file. A few offer a lock-and-shop product that holds a rate for a set period while you look, usually at a cost and usually at a slightly worse rate than the market. If a bad week would end your search, that product is worth asking your lender about by name.
What does it cost to extend a rate lock?
Extensions are priced in fractions of a point of the loan amount and the cost rises with the length of the extension, so a short extension is cheap and a long one is not. The amount varies by lender and is not standardized, which is exactly why you should ask for the extension schedule in writing when you first lock rather than when you need it. Buyers almost never ask, and it is the fee that shows up most often at the worst moment.
If I lock and rates drop a lot, am I stuck?
You are stuck with that rate for this loan unless your lock includes a float-down option, but you are not stuck forever. Refinancing is always available later, at the cost of new closing expenses and a fresh loan term, so the practical question is how far rates would have to fall to make that worth doing. Ask your lender to tell you the break-even before you sign, not after.
Call your loan officer today and ask three specific things: what rate you can lock right now, what a 60 and a 90 day lock cost against a 30, and whether there is a float-down. Write the answers down. If you do not have a contract yet, ask instead to be pre-approved at a rate a half point above today’s, so you know your real ceiling. Then bring us those numbers and we will tell you honestly what they buy you in New Hanover, Brunswick or Pender this month.
