If you're buying a home in Delaware County, you're probably asking yourself: Am I making a smart decision?

It's a reasonable question. You're about to make the largest purchase of your life. You want to know the home you buy today will hold its value — or better yet, grow — over the years you live there.

The problem is, most of the data you'll find online is either too broad (county averages that mask huge differences between neighborhoods) or too shallow (Zillow estimates based on algorithms, not actual sales).

We took a different approach.

What We Actually Track

Using 33 years of MLS transaction records, we analyze how home values have actually performed — neighborhood by neighborhood, school district by school district — across Delaware, Chester, and Montgomery counties.

This isn't Zillow estimates or tax assessments. It's transaction-to-transaction data — what sellers paid versus what they walked away with.

But Not All Neighborhoods Perform Equally

County-wide averages are encouraging, but they mask huge differences between areas. Some neighborhoods in our data showed gains well above the county average. Others appreciated at half that rate.

The difference often comes down to three factors:

1. School District

School district is the single biggest factor in long-term home value performance in Delaware County. Families pay a premium for top-rated districts — and that premium tends to hold over time. Districts like Garnet Valley, Rose Tree Media, Wallingford-Swarthmore, and Radnor consistently show stronger appreciation and faster sales than the county average.

2. Neighborhood Demand

Even within the same school district, neighborhoods perform differently. A well-located neighborhood with strong community appeal will typically outperform a similar-priced neighborhood with less demand. You can see this in the data: some neighborhoods consistently sell faster and with fewer price reductions than their neighbors.

3. Price Point

Delaware County offers a wider range of price points than neighboring Chester County, making it attractive to buyers priced out of some Chester County districts. The sweet spot varies by district, but homes priced correctly in strong school districts tend to sell quickly and hold value well.

How to Research Before You Buy

When you're evaluating a home, price is only part of the equation. Here's what we recommend looking at:

1. How has this specific neighborhood appreciated over time? — Not the zip code. Not the school district average. The actual neighborhood.
2. How long are homes sitting on the market here? — Shorter days on market typically indicates stronger demand and better value retention.
3. What percentage of listings have had price reductions? — High price reduction rates (50%+) signal a softer market — which can mean negotiation opportunities for buyers.
4. What did similar homes sell for in the last 6–12 months? — Recent comps matter more than asking prices.
5. Is this neighborhood trending up, flat, or cooling? — A great house in a cooling neighborhood may not hold value as well as a good house in a rising one.

Why Delaware County?

Delaware County offers something unique in the Philadelphia suburbs: access to top-rated school districts at price points below Chester County, with easier commutes to Center City, the airport, and Wilmington.

Districts like Garnet Valley and Rose Tree Media attract families looking for strong schools without the premium of Unionville-Chadds Ford or Tredyffrin-Easttown. Meanwhile, areas like Wallingford-Swarthmore and Radnor offer walkable, character-rich communities that hold value exceptionally well.

The 100.1% average return we tracked in 2025 — the highest of any county in our analysis — reflects this sustained demand.
