Average home price in New Castle County, DE
The typical home in New Castle County, DE sold for $389,900 during May 2026. That is the median — half of the homes that sold went for more than that, half for less.
Almost everyone searches for the "average" price, and almost every published figure — including this one — is the median instead. The difference matters. A true average is dragged upward by a handful of very expensive sales, so in a metro with a few multi-million-dollar homes it can sit well above anything an ordinary buyer would ever pay. The median is simply the sale in the middle of the list, which is why it is the number that describes a normal home.
Homes currently on the market in New Castle County, DE are asking a median of $425,000. Do not read the gap between that and $389,900 as a discount you can expect to negotiate. Those are two different sets of homes — one is what sold, the other is what has not sold yet — and asking prices skew high precisely because the homes priced too high are the ones still sitting there. The honest measure is what each home got against its own asking price, and in New Castle County, DE that came to 100%.
Measured by size rather than by house, homes in New Castle County, DE are selling for about $214 per square foot. That is the fairer comparison when you are weighing one neighborhood against another, or this year against last, because the typical price moves whenever the mix of what happens to sell shifts — a run of large houses lifts it without anything actually getting more expensive.
This page is about what a home costs, not which way that is heading. For the record, the figure is 5% higher than the same stretch a year ago.
