It is worth it if you can carry the payment without thinning your reserves, because the 15-year is 69 basis points cheaper than the 30-year right now: 6.71 percent against 7.40 percent in Freddie Mac’s survey as of October 15, 2026. The cost of that saving is about $706 a month more on a median New Hanover County home, which is why most of the buyers who ask us this question end up taking the 30-year and prepaying it instead.
The gap between the two rates is doing something unusual at the moment, and it is worth understanding before you choose. The 30-year rose six weeks running, from 6.66 percent in late August to 7.40 percent, which is 74 basis points in eight weeks and the highest reading since November 2023. The 15-year moved less, and slipped 2 basis points last week to 6.71 percent from 6.73 percent. When the long rate runs and the short rate does not, the shorter loan gets relatively cheaper.
That makes the arithmetic better than it has been in a while. It does not change the thing that decides this for most households, which is cash flow, and on this coast cash flow includes an insurance line that has been moving fast.
What the two loans cost on a real Wilmington house
Take the New Hanover County median sale price of $464,000 for the three months ending September 2026 and put 20 percent down, for a loan of $371,200.

A saving of about $335,000 in interest is not a rounding error, and we are not going to talk anyone out of it. But look at the two monthly numbers next to each other. The 30-year payment on that house is close to the county median payment, which is the number local lenders are underwriting every day. The 15-year payment is $706 above it, and that $706 is committed for fifteen years whether or not your insurance renewal arrives 16 percent higher.
Run the same math on the other two counties and the shape holds. On the Brunswick County median of $394,000 the gap is about $600 a month; on the Pender County median of $499,000 it is about $760. Our monthly mortgage update carries the current rates and the payment math on a $500,000 purchase if you want to run your own price point.
The comparison most people should actually run
The real alternative to a 15-year loan is not the 30-year as scheduled. It is the 30-year with the 15-year payment made voluntarily, and the numbers there are closer than people expect.
Put $3,277 a month against that same $371,200 at 7.40 percent, the 15-year payment applied to the 30-year note, and it pays off in about 16 years and three months with roughly $268,000 of total interest. The actual 15-year loan, at the lower 6.71 percent rate, retires in 15 years with about $219,000 of interest. So the 15-year wins by roughly $49,000 and fifteen months, and that is the honest size of the prize.
What you are buying with that $49,000 is a commitment. What you give up is the option to stop. If your income drops, if the heat pump goes, if a renewal lands higher than you budgeted, the 30-year lets you fall back to $2,570 next month without asking anyone’s permission. The 15-year does not. We tell buyers to price the commitment honestly: $49,000 over fifteen years is about $272 a month of value, and the question is whether that is worth giving up the ability to breathe.
Who the 15-year actually fits here
Three groups, in our experience. Buyers arriving from the Northeast or the Raleigh and Charlotte markets with real equity from a sale, who are buying down in price and have the payment comfortably covered. Buyers inside fifteen years of retirement who want the house paid off before the income changes. And buyers who were going to put far more down anyway and would rather keep some cash invested than sink it all into the purchase price.
We advise against it for first-time buyers, for anyone whose reserves after closing would be under six months of the higher payment, and for second-home or beach-rental buyers, where the carrying costs are already the most volatile part of the budget. A coastal second home with a 15-year note and a wind deductible stated as a percentage of the dwelling coverage is a tight combination in a bad year.
One practical note on qualifying. The higher payment counts against your debt-to-income ratio, so choosing a 15-year term reduces the price you can be approved for, sometimes substantially. If you are shopping at the top of your range, the 15-year quietly takes houses off your list. Our Buyer Advantage Program starts with that number rather than with a house, because it determines everything after it.
Nobody can tell you where rates go from here, and the case for each loan depends on an unknown. If the 30-year falls back toward where it sat a year ago at 6.27 percent, a 30-year taken today can be refinanced and the interest saving you locked in with a 15-year becomes less impressive. If rates stay here or climb, the 15-year looks smarter every year. We do not forecast, and anyone who tells you confidently which way this goes is guessing. There is also a quieter risk specific to this market: your escrow is not fixed. Property taxes reset on county reappraisal cycles, Brunswick County’s next revaluation takes effect January 1, 2027, and coastal insurance has been approved for back-to-back increases. A payment that fits today at the edge of your budget may not fit in 2028, and the 15-year gives you no room to absorb that. Talk to a lender who will model both loans with a realistic escrow, not a placeholder.
Related questions people also ask
What is the 15-year mortgage rate right now?
Freddie Mac’s weekly survey put the 15-year fixed average at 6.71 percent as of October 15, 2026, down slightly from 6.73 percent the week before, against 7.40 percent for the 30-year fixed. A year earlier the same survey showed 5.52 percent on the 15-year and 6.27 percent on the 30-year, so both are meaningfully higher than they were. These are national averages rather than quotes, and your own rate will depend on credit score, down payment, loan size and the lender. Treat the survey as the direction of the market and get two or three actual quotes before you compare terms.
Can I just pay extra on a 30-year mortgage instead?
Yes, and for most households it is the better choice. Paying the 15-year amount on a 30-year note retires the loan in a little over sixteen years instead of fifteen, and costs roughly fifty thousand dollars more in interest at current rates, which is the price of keeping the option to stop. The flexibility is worth real money in a market where insurance renewals and reappraisals can move your escrow without warning. Confirm with your lender that extra payments are applied to principal and that there is no prepayment penalty, then set the higher amount up automatically so the decision is made once.
Does a 15-year mortgage help me qualify for more house?
No, it does the opposite. Lenders qualify you on the monthly payment relative to your income, and the 15-year payment is substantially higher than the 30-year payment on the same loan amount, so the price you can be approved for goes down. Buyers who want the shortest possible term and the largest possible house are pulling against themselves. Decide which of the two matters more before you start touring, because switching terms late in a search usually means revisiting the price range as well.
Ask a lender for the same house priced both ways, with a real property tax figure for the county you are buying in and a real insurance quote for the address, not an estimate. The 15-year decision is almost always decided by that escrow line rather than by the interest saving. Send us the two scenarios and the areas you are considering and we will walk through them with you, and we will say plainly if the payment looks tight for the house you are aiming at.
