Live Poll

Do you believe now is a good time to purchase a home in your area?

Existing home sales in Delaware dropped to 1,222 units in August 2026, marking a 7.0% decline from July and a 4.5% decrease compared to the same month last year. While sales slowed, the median home price in the state rose to $401,632.

Why it matters

High mortgage rates, which hit 7.20% as of September 18, 2026, have cooled buying activity compared to the prior year. This shift has altered local affordability, even as inventory levels provide more options for persistent house hunters.

Delaware recorded 1,222 existing home sales in August with a median price of $401,632, which is 3.8% higher than in August 2025. Total inventory reached 4,712 homes statewide, with properties spending an average of 48 days on the market.

The details

Home sales generally reflect mortgage rates locked in one or two months prior to the closing date, explaining the recent dip in volume. As inventory levels reached 4,712 units in August, the market transition has provided prospective buyers more room to negotiate with sellers. While statewide averages indicate a cooling period, sub-regions show varied activity, with New Castle County homes selling in an average of 27 days.

The Home Front

Delaware housing activity is mirroring a broader national trend where elevated borrowing costs dampen transaction volume despite constrained supply. This environment signals a departure from the record-high median pricing observed in July 2026.

If you are house hunting, use the increased inventory of 4,712 homes to test your negotiation strategy with sellers. Monitor local rate trends closely, as the gap between September 2025 and 2026 rates demonstrates how significantly borrowing costs affect your monthly budget.

The takeaway

Higher mortgage rates have effectively slowed home purchasing across Delaware compared to last year. If you are entering the market, focus on days-on-market metrics in your specific county to better time your offers.
