The question is really which loan you are comparing, because the cheap mortgage on your current house does not move with you. At this week’s rates, financing $400,000 on a Wilmington purchase costs about $2,748 a month and roughly $589,000 in interest across thirty years, so for most people relocating here the honest answer is to buy with as little mortgage as the rest of the plan allows.
We have this conversation at kitchen tables most weeks, usually with buyers coming from New Jersey, Ohio, Pennsylvania or Raleigh who are sitting on a 3 percent loan and a lot of equity. The instinct is to protect the 3 percent loan. The problem is that the loan belongs to the house you are selling.
So the real decision is how much of the Wilmington house to finance, and what the money you keep has to earn to justify the choice.
What new money costs here right now
Freddie Mac’s weekly survey put the 30-year fixed at 7.32 percent for the week ending October 22, 2026, down from 7.40 percent the prior week and up from 6.19 percent a year earlier. The 15-year averaged 6.68 percent.
By our arithmetic on those averages, a $400,000 loan at 7.32 percent runs about $2,748 a month in principal and interest, and about $589,000 in interest if you carry it the full thirty years. The same balance on a 15-year at 6.68 percent is about $3,524 a month. Our monthly mortgage update keeps the current survey rate and the payment math on a Wilmington-priced house, and we worked through the shorter-term question in is a 15-year mortgage worth it at these rates.
Framed as a return, retiring a 7.32 percent mortgage is a guaranteed 7.32 percent, with no sequence risk and no tax drag on the gain. That is a high bar for a retirement portfolio to clear reliably. It is not an argument that applies to a 3 percent loan, which is why people who bought or refinanced in 2020 and 2021 should generally keep those loans, and why that fact is irrelevant the moment they sell.

What North Carolina does and does not do for retirees
Two parts of the state tax picture are genuinely good, and one that people count on usually does not apply.
The good news first. North Carolina’s individual income tax rate is 3.99 percent for taxable years after 2025, down from 4.25 percent in 2025, and the Department of Revenue allows you to deduct from federal adjusted gross income the taxable amount of your Social Security benefits on Form D-400 Schedule S. In practice that means Social Security is not taxed by the state and the rest of your retirement income is taxed at a flat rate, which is simpler than what most of our buyers leave behind.
The part that usually does not apply is property tax relief. North Carolina’s elderly or disabled homestead exclusion removes the greater of $25,000 or 50 percent of the appraised value of a permanent residence, but the owner’s income for the prior year cannot exceed $38,800 for 2026. The circuit breaker deferment uses the same limit and a second tier at 150 percent of it. Most people selling a Northeast or Midwest house and buying on this coast are above those thresholds, often well above. We mention it because online guides to retiring in North Carolina rarely mention the income test, and buyers arrive expecting a senior discount that is not coming.
What a paid-off house still costs
Paying cash removes the mortgage. It does not remove the three bills that make coastal ownership expensive, and on this coast those are the ones that grow.
Insurance is the first. Coastal North Carolina homeowners typically carry a main policy with a separate named-storm or wind-and-hail deductible, plus flood coverage, and the wind portion often comes through the North Carolina Beach Plan. Our coastal insurance guide and flood zone guide cover how those interact. Taxes are the second, and county revaluations here have been moving sharply. Dues are the third, and in the amenity communities our retiring buyers like most they are not small: we broke down what they actually buy in Landfall HOA and club fees. Our line-by-line cost of living guide puts all of it in one place.
The other thing a paid-off house costs you is access to the money. Home equity on this coast is slow: the median home takes 61 days to sell in New Hanover County, 83 in Pender and 93 in Brunswick on September 2026 data. If a plan requires reaching that equity in a hurry, the house is a poor place to keep it, and arranging a line of credit after you retire is harder than arranging one while you still have employment income.
We are brokers, not financial advisers, and the piece of this we cannot answer is yours: your tax bracket, your required minimum distributions, how much cash you need outside the house, and whether selling appreciated assets to fund a cash purchase triggers a bill that wipes out the interest you saved. Run the payoff question past your CPA and your adviser before you run it past us. Two local notes we can add. First, paying cash removes two free inspections of your own purchase, because without a lender nobody orders an appraisal and nobody runs a flood hazard determination. We would buy both anyway, and our flood zone guide above explains what a determination and an elevation certificate change. Second, a cash offer is worth real money to a seller in a market where the median listing takes two to three months to close, so if you are paying cash, make sure your offer is priced to collect that advantage rather than just mentioning it.
Related questions people also ask
Is it better to pay cash or get a mortgage when you retire?
At current rates, paying cash is the stronger default, because retiring a mortgage is a guaranteed return equal to the interest rate and today’s rate is high by the standards of the last decade. The counterargument is liquidity: a paid-off house locks money into an asset that takes weeks or months to sell, and borrowing against it is harder once you no longer have employment income. The common middle path is a smaller mortgage plus a cash reserve you can actually reach. Decide the reserve first, then size the loan.
Does North Carolina tax retirement income?
Partly. The state allows a deduction for the taxable amount of Social Security benefits included in your federal adjusted gross income, so Social Security is effectively not taxed, while withdrawals from a retirement account and most pension income are taxed at the state’s flat individual rate. Certain long-vested government retirement benefits are treated differently here, so ask a North Carolina CPA if you are a retired teacher, state employee or federal retiree. The flat structure makes the planning simpler than in most states our buyers come from.
Do seniors get a property tax break in Wilmington, NC?
There is a program, but it is income-tested and most relocating buyers do not qualify. North Carolina’s elderly or disabled homestead exclusion removes the greater of twenty-five thousand dollars or half the appraised value of a permanent residence, and for 2026 the owner’s prior-year income cannot exceed $38,800 (N.C. Department of Revenue 2026 homestead income limits). A separate circuit breaker deferment uses the same limit with a second tier above it. Both are applied for through the county tax office, and both require that the home be your permanent residence rather than a second home.
Decide your cash reserve before you decide your mortgage, then price two versions of the same Wilmington house: all cash, and financed with the loan that leaves that reserve intact. Ask your CPA what funding the cash version costs in tax, and bring both versions to our team with the communities you are considering. We will put the real tax, insurance and dues numbers next to each so you are comparing the cost of owning rather than just the cost of borrowing.
