Picture two homes a few streets apart in Villanova, both listed at the same price, both zoned 19085, both photographed with the same stone facades and mature trees that make this stretch of the Main Line recognizable from a listing photo alone. One of those homes sits in Radnor Township, Delaware County. The other sits in Lower Merion Township, Montgomery County. Neither buyer will see that distinction highlighted on the listing sheet. Both will feel it every year at tax time, and in ways that don't move in the direction most people assume.
Villanova is not one municipality. It never has been. The community straddles the border between Lower Merion Township in Montgomery County and Radnor Township in Delaware County, and that line runs directly through the neighborhood, not around it. For a buyer comparing two Villanova houses, that boundary changes more than which mailbox gets which junk mail. It changes your school district, your police department, and the math behind your annual tax bill in a way the nominal tax rate alone won't tell you.
The Line the Listing Photo Doesn't Show
Public school assignment in Villanova follows the township line exactly. Families on the Radnor Township side send children to Radnor Elementary, Radnor Middle School in Wayne, and Radnor High School in St. Davids. Families on the Lower Merion Township side are zoned into Gladwyne Elementary, Black Rock Middle School, which sits inside Villanova itself, and Harriton High School in Rosemont. There is no opting between them by preference. The parcel decides.
Police coverage splits the same way. Radnor Township Police Department patrols the Delaware County portion of the community, while Lower Merion Township Police Department covers the Montgomery County side. Villanova University maintains its own campus safety department, and the university's main campus itself sits within Radnor Township, not Lower Merion.
None of this shows up in a portal search for "Villanova homes for sale." It shows up in the county assessor's parcel record, and it's worth pulling before you fall for a house.
Same Rate Doesn't Mean Same Bill
Here's where the math gets counterintuitive, and where a buyer comparing two Villanova houses can walk into a surprise if they only glance at millage rates.
Lower Merion Township generally carries a higher nominal millage rate than Radnor Township. On paper, that looks like the more expensive place to own. But Pennsylvania counties don't all assess property at the same fraction of market value, and Montgomery County's assessed values run at a noticeably lower percentage of true market value than Delaware County's do. Radnor's lower millage rate gets applied against a much larger assessed base. Lower Merion's higher millage rate gets applied against a much smaller one. The two effects partially cancel each other out, which means the township with the scarier-looking tax rate is not automatically the township with the bigger bill.
| Layer | Radnor Township side | Lower Merion Township side |
|---|---|---|
| County | Delaware County | Montgomery County |
| School district | Radnor Township School District | Lower Merion School District |
| Police | Radnor Township PD | Lower Merion Township PD |
| Assessment approach | Assessed value runs closer to actual market value | Assessed value runs at a smaller fraction of market value |
If you're comparing two specific addresses, don't stop at the headline millage number for either township. Pull the actual assessed value and the current combined rate for that exact parcel. Montgomery County publishes its current municipal and school millage rates directly, and Radnor Township does the same for its own jurisdiction. Both are five minutes of homework that can reorder which house is actually the better deal.
What Just Happened on the Radnor Side
If your Villanova house sits in Radnor Township, the math changed this year. The Radnor Township School Board approved a 3.36 percent tax increase for the 2026-2027 school year, raising the school district millage rate from just under 15.8 mills to about 16.33 mills. Combined with Radnor Township's own real estate tax of 2.4852 mills and Delaware County's 3.873 mills, a Radnor-side Villanova homeowner is now looking at a combined rate somewhere around 22.7 mills, not counting whatever the assessed value on that specific parcel happens to be.
Tax bills reflecting the new school rate were mailed to Radnor Township School District residents by July 1, 2026. If you're touring a Radnor-side home this fall, the current owner's tax bill already includes this year's increase, so ask for it rather than relying on a listing sheet's estimate, which may still reference last year's rate.
The Appeal Window Already Closed This Year
One more timing detail that matters if you're closing on a Villanova home in Delaware County this fall: property owners who believe their assessed value is too high can file a formal appeal with the county, but the deadline for this cycle was August 1, 2026. That window has already passed. Whatever assessment sits on a Radnor-side parcel right now is the one you'll inherit at closing, and it will stay that way until next year's appeal period opens. If a house you're considering has an assessed value that looks out of step with its actual market price, that's worth raising with the seller or your inspection team before you write the offer, not after you own it.
For context on where Villanova sits overall, current data from Ownwell puts the median effective property tax rate in the 19085 zip code at 2.02 percent, well above the national median of 1.02 percent and modestly below the Pennsylvania state median of 2.75 percent. That's a useful anchor, but it's a blended number across a community that is, as we've established, actually two different tax systems wearing one name.
Why the Median Price You See Online Won't Settle Anything
Search for Villanova's median home price and you'll get answers that don't agree with each other, sometimes by hundreds of thousands of dollars. Part of that is ordinary differences in automated valuation methodology. Part of it is something more specific to this neighborhood: Villanova's actual transaction volume in any given month is small, often only a couple dozen closed sales, so a handful of high-end estate sales on one side of the township line can swing a monthly median dramatically without reflecting what a typical buyer will actually pay. A single-digit sale count is not a stable base for a percentage change, and any site quoting one should be read as a snapshot, not a trend line.
The practical takeaway is the same one that runs through this whole piece. A number that says "Villanova" is describing two different markets stapled together by a shared name. The only median that matters to you is the one built from comparable sales on your specific side of the township line.
What to Confirm Before You Write an Offer
A few minutes of parcel-level homework changes what you're actually comparing:
- Confirm the township and county for the specific parcel, not just the "Villanova" name on the listing.
- Pull the current combined millage rate and the assessed value for that parcel from the county, not an estimate from a listing sheet.
- Ask which elementary, middle, and high school the property is zoned for, since it follows the township line rather than personal preference.
- Check whether this year's assessment appeal window is open or closed in that county, since Delaware County's closed August 1 this year.
- Ask your title company to confirm the transfer tax calculation early, since county and municipal transfer tax components can differ depending on which township the parcel sits in.
A Few Common Questions
Is Villanova University in Radnor Township or Lower Merion Township? The university's main campus sits within Radnor Township, Delaware County.
Can a family choose which school district their Villanova home is zoned for? No. School assignment follows the township and county line for that specific parcel, not personal preference or which side of a street feels closer to one school or another.
Does the closing process change based on which township a Villanova home sits in? The core process is the same, but the transfer tax math and the specific county and school forms involved can differ, so it's worth confirming the exact jurisdiction with your title company before you finalize a closing estimate.
If you're comparing two Villanova addresses and the numbers on paper aren't adding up the way you expected, that's usually a sign you're looking at two different tax systems, not one confusing house.
