In Villanova, the Median Price Depends on Which Side of Spring Mill Road You're Standing On

A listing for a stone Colonial in Villanova's Ardrossan section calls the property part of "the Gold Coast of Radnor Township." It reads like marketing copy, and it is, but it's also more accurate than most buyers realize. That phrase names a specific township on purpose, because Villanova itself is not a township. It has no borough government, no single tax rate, and no single school district. It is a postal address that two separate municipalities happen to share, and the line between them runs close enough to Spring Mill Road that a buyer comparing two Villanova listings a few blocks apart may be comparing two different governments, two different school assignments, and two different tax bills.

That's the part the median price never tells you.

Two Snapshots, One ZIP Code

Look at Villanova's reported median home price at two points this year and the number moves in a way that has nothing to do with the season. In July 2026, one national listing aggregator put the Villanova median list price at roughly $2.09 million. Two months later, in September 2026, the same aggregator had it at roughly $1.8 million. That's not a market correction. Villanova has a small enough pool of active listings that a single large estate coming on or off the market can pull the median hundreds of thousands of dollars in either direction within a single quarter.

A thin, unstable sample is one problem. The other problem is what's inside that sample. Villanova's active listings aren't drawn from one neighborhood with consistent housing stock. They're drawn from two neighborhoods with different lot sizes, different architectural eras, and different governments, all filed under the same ZIP code. A median calculated across both sides tells you almost nothing about what either side actually costs.

The Line Nobody Draws on a Listing Sheet

Villanova sits at the center of the Main Line, where Route 30 (Lancaster Avenue) crosses Pennsylvania Route 320 (Spring Mill Road). That intersection is also close to where two townships meet. According to Wikipedia's entry on Villanova, Pennsylvania, the community straddles the border of Lower Merion Township in Montgomery County and Radnor Township in Delaware County. It's not a soft cultural distinction. It's a hard administrative one, and it decides which office sends the tax bill and which school district assigns the bus route.

Radnor Township's own government site lists Villanova as one of the unincorporated areas situated in or partially in the township, alongside St. Davids, Rosemont, and Wayne. That's the Delaware County side. Public school children who live in the Radnor Township portion of Villanova attend Radnor Elementary, Radnor Middle School in Wayne, and Radnor High School in St. Davids, all part of the Radnor Township School District, whose administrative boundaries are published directly on the district's own boundary maps.

Cross into the Lower Merion Township portion, generally the streets northeast of Spring Mill Road toward Gladwyne, and the governing structures change entirely. According to Kiddle, children there attend Lower Merion School District schools, specifically Gladwyne Elementary, Black Rock Middle School, and Harriton High School. Same ZIP code. Different county. Different school system from kindergarten through graduation.

What the Two Sides Actually Look Like

The Radnor Township side is where you'll find the Villanova most people picture when they hear the name: stone and brick estates on multi-acre lots along Spring Mill Road, Mount Pleasant Road, and Ithan Avenue, many dating to the early 1900s through the 1930s. The Ardrossan section sits here, the estate area agents describe as the Gold Coast of Radnor Township, and it's the kind of inventory that can single-handedly move a small sample's median when one of these properties transacts.

The Lower Merion Township side reads differently on the ground. Listings there run toward Gladwyne, and the marketing language shifts with them, emphasizing the Lower Merion School District rather than Radnor's. Homes here range from historic estates on their own acreage to smaller ranch and split-level properties, a wider spread of housing stock than the Radnor side's estate-heavy inventory.

Why This Matters More Than the Number Does

A buyer who pulls up "Villanova" on a search and sorts by price is really sorting across two housing markets that happen to share a name. That has three practical consequences worth working through before you write an offer.

The tax bill isn't portable across the line. Radnor Township and Lower Merion Township set their own municipal levies, and Radnor Township School District and Lower Merion School District set their own school millage. A buyer who compares the current tax bill on a Radnor-side listing to a Lower Merion-side listing and assumes the difference reflects assessed value alone is missing that two separate taxing bodies are involved, not one market pricing similar homes differently.

The comp set you're handed may not be the comp set you think it is. If an agent or an automated valuation pulls "recent Villanova sales" without separating them by township, the result blends Ardrossan-scale estate sales with smaller Lower Merion-side transactions. That blended number is real, but it doesn't describe either sub-market on its own. Before trusting a comp, ask which side of Spring Mill Road each comparable sale actually sits on.

School assignment isn't guaranteed by the mailing address. Two houses with matching Villanova addresses, a few streets apart, can feed entirely different school districts. Anyone weighing a Villanova purchase around a specific school district should confirm the parcel's township directly with that township's tax assessment office or the relevant school district's boundary office rather than relying on the address alone.

Two Questions Worth Asking Before You Compare Two Listings

Which township is this parcel actually in? Delaware County and Montgomery County maintain separate property records, and the township determines both the school district and the base municipal tax rate. A quick check with the county parcel record settles this before you get further into a decision.

Whose comp set produced this number? A median or an automated estimate for "Villanova" is only useful once you know whether it's pulling from the Radnor Township side, the Lower Merion Township side, or both blended together. Ask for the underlying sales, not just the summary figure.

Villanova rewards a buyer who treats the name as a starting point rather than an answer. The number on the listing sheet describes a house. The line running near Spring Mill Road describes everything the listing sheet doesn't.
