Delaware’s housing market in September 2026: rates crossed 7% and the market felt it

Four straight weekly rate increases pushed the 30-year fixed above 7% for the first time in nearly two years. Here is what that means if you are moving to, from or within Delaware.

September had one dominant story, and it was not inventory or prices. It was the cost of borrowing. The Freddie Mac 30-year fixed average rose in every single week of the month, and by the last week it had crossed a line buyers had not seen in nearly two years.

The 7.03% reading on September 24 was the first time the 30-year average topped 7% since January 2025. The climb did not stop at the end of the month either. The first survey of October came in at 7.28%.

To put that in plain dollars: on a $400,000 loan, moving from 6.71% to 7.03% adds roughly $85 to the monthly principal and interest payment. Not catastrophic on its own, but it lands on top of two years of price growth, and it is enough to push some buyers down a price tier or out of the market for a while.

What rising rates actually do to a market like ours

There is a reflex to read “rates up” as “bad for everyone.” It is more specific than that. Higher rates reduce how many buyers can qualify at any given price. Fewer qualified buyers means less competition for each home, which means homes sit longer and sellers negotiate more.

If you can carry the payment, a higher-rate market is frequently a better market to buy in than a low-rate one. You compete with fewer people, you are less likely to waive an inspection to win, and you can ask for things buyers could not ask for in 2021. The rate on your loan can be refinanced later. The price you paid and the terms you accepted cannot.

Where Delaware’s three counties stand

Delaware’s counties continue to behave like three separate markets. These are the most recent county figures published by the Delaware Association of REALTORS.

New Castle County

Still the tightest market in the state at roughly two months of supply. Even with rates climbing, well-prepared homes in the Wilmington, Newark and Middletown corridors continue to move. If you are buying here, stay pre-approved and be ready to act. New Castle County homes.

Kent County

The value play, with the lowest median of the three counties and about three months of supply. For military families arriving at Dover Air Force Base outside of peak PCS season, fall usually means less competition. Kent County homes, Dover homes and PCSing to Dover AFB.

Sussex County

The most inventory and the most negotiating room in Delaware, at roughly five and a half months of supply. Beach and retirement buyers who were outbid in past years are finding sellers far more willing to talk. Sussex County homes and Delaware beach and summer homes.

If you are buying in Delaware this fall

• Get re-approved, not just pre-approved. An approval letter written in July assumes a rate that no longer exists.
• Ask your lender about a temporary buydown. Sellers in slower pockets, especially in Sussex County, are often more willing to fund points than to cut the list price.
• If you are VA eligible, use it. No down payment and no mortgage insurance matters more, not less, when rates are high.
• Shop the loan, not just the house. A quarter point spread between lenders is real money over 30 years.
• Do not wait for a better rate to start looking. Learning the neighborhoods takes time, and nobody rings a bell at the bottom.

If you are selling and moving out of state

• Price to today’s buyer pool, not to what your neighbor got last spring. The qualified pool is smaller than it was.
• Put your money into condition and photography before you put it into a price cut.
• Consider offering closing cost help or a rate buydown. It often costs less than a price reduction and moves more buyers.
• If you have already moved, do not let the house sit unattended. Empty homes show badly and invite problems.

Looking into the fall

October opened at 7.28%, so the pressure has not let up. If rates hold at this level, expect inventory to keep building, days on market to stretch, and price growth to flatten across all three counties. Sussex County will likely stay the friendliest market for buyers, New Castle County the most competitive, and Kent County somewhere in between.

The group most affected is the one in the middle: buyers who qualified comfortably in the spring and are now right at the edge. If that is you, it is worth a conversation with a lender before you decide the move is off.

Frequently asked questions

What were mortgage rates in September 2026?

The Freddie Mac 30-year fixed average rose every week of September 2026, from 6.71% on September 3 to 7.03% on September 24. That was the first time the average topped 7% since January 2025. It climbed again to 7.28% in the first week of October.

Is now a bad time to buy a house in Delaware?

Higher rates raise the monthly payment, but they also thin out competition. Delaware had more inventory in 2026 than in recent years, especially in Sussex County, so buyers who can absorb the payment often face fewer competing offers and more room to negotiate on price, repairs and closing help.

What is the median home price in Delaware by county?

The most recent county breakdown from the Delaware Association of REALTORS, for June 2026, put the median sold price at about $398,000 in New Castle County, $355,000 in Kent County and $470,000 in Sussex County.

How do higher mortgage rates affect sellers in Delaware?

When rates rise, the pool of buyers who qualify at a given price shrinks. Pricing correctly from day one matters more, and sellers should expect to consider rate buydowns or closing cost help as negotiating tools rather than cutting the price outright.

Can I still buy a Delaware home with a VA loan in this market?

Yes. VA loans still offer no down payment and no private mortgage insurance for eligible buyers, which lowers the cash needed up front even when rates are higher. Doreen Sawchak is VA Loan Certified and works with local VA lenders.
