Two SEPTA surface trolleys, Routes 101 and 102, still run the same route they've run since 1907, carrying riders from Media and Sharon Hill to the 69th Street Terminal, where a transfer onto the Market-Frankford Line continues on toward Center City. The trolleys are unglamorous. Nobody buys a house because of a transit line built before the first Model T rolled off the line. But if you trace the map of where Delaware County home prices are highest and lowest, the trolley corridor and the walkable downtowns strung along it explain more of that map than almost anything else on offer, including the school district rankings most buyers reach for first.
That matters right now because the county-wide median price, the number every portal leads with, is close to useless as a planning tool here. It isn't wrong. It's just averaging together two markets that don't compete for the same buyer, don't move on the same timeline, and don't respond to the same forces.
One Median, Two Housing Markets
In the three months ending April 2026, the county-wide median sale price in Delaware County was $349,000, down slightly from the same period a year earlier. That figure sits in a strange middle ground, because almost nothing in the county actually sells for it. Delaware County holds some of Pennsylvania's most expensive zip codes in Wayne and Radnor and some of its least expensive in Chester and Sharon Hill, all inside the same county boundary.
The scale of that spread showed up clearly in 2025. Radnor Township's median sale price reached $1,192,500 for the year, a 32.1 percent jump over 2024, according to HomExpert Market Report data cited by Delco.Today's parent publication. In the same year, Chadds Ford Township's median dropped 41.8 percent, from $687,500 down to $400,000. Two towns in the same county, moving in opposite directions by double digits, in the same twelve months. A single median price cannot represent both of those stories at once, and it isn't trying to.
The Explanation That's Too Easy
Ask most people why Wayne costs more than Woodlyn and the answer arrives fast: better schools. Radnor Township, Wallingford-Swarthmore, and Rose Tree Media school districts do routinely rank among Pennsylvania's strongest, and school district is a real factor in how Delaware County buyers choose where to look.
But school quality alone doesn't hold up as the full explanation once you look at how these boundaries formed. Strong districts in Delaware County didn't create strong towns. They followed a tax base that was already established a century earlier, in places that already had the infrastructure to attract and keep residents who could fund good schools in the first place. The order of causation runs backward from how it's usually told.
What Actually Drew The Line: A Railroad, Then A Trolley
The Pennsylvania Railroad's Main Line laid a string of estates and college campuses from Bryn Mawr through Wayne toward Paoli in the 19th century. Swarthmore College opened its doors in 1864. Haverford College predates it by a generation. Villanova and Cabrini followed. By 1900, the western half of Delaware County had a college town in nearly every borough, and a trolley line running through most of them, a network that still holds the distinction of being the longest continuously operating trolley system in the country.
Those towns never stopped being walkable. Media, Swarthmore, Wayne, and Havertown still have the kind of downtown where you can get coffee, dinner, and dry cleaning done on foot, a pattern that's increasingly rare among Philadelphia's collar counties and increasingly valuable to buyers who want it.
The county's eastern river towns tell a different story. Marcus Hook, Chester, and Eddystone built an economy on shipyards, refineries, and steel mills. Sun Shipbuilding alone employed 35,000 people at its World War II peak. That industrial base collapsed through the 1970s and 1980s. Sun Shipbuilding closed for good in 1989, and Chester lost roughly half its population in the decades that followed. The Main Line boroughs, built around colleges and commuter rail rather than heavy industry, simply had nothing comparable to lose. That's the divide still visible on a price map in 2026, and it was set in motion well over a century before either the Radnor Township school board or the Wallingford-Swarthmore school board existed in their current form.
Same County, Different Commutes
Commute time to Center City looks like it should explain the price gap cleanly. It doesn't, not entirely, and the exception is instructive.
- From Havertown, 30th Street Station is roughly 25 minutes away.
- From Wayne, it's closer to 35 minutes.
Havertown is faster to Center City and less expensive than Wayne. If commute time alone drove price, that ranking would run the other way. What Wayne is selling instead is the full Main Line package: the college-town anchor at Villanova next door, the century of continuous walkable downtown, the estate-era housing stock. Transit access is part of the price story in Delaware County, but it's not the whole price story, and buyers who shop on commute time alone will misjudge more than one town in this county.
What Different Delaware County Price Points Are Actually Buying
Town-level figures make the pattern concrete. These are typical home values by area as of mid-2026, drawn from the same index so they compare cleanly against each other, even if they sit above or below the flatter county-wide median sale price cited earlier.
| Area | Typical Home Value | What It Reflects |
|---|---|---|
| Media | $565,355 | County seat, State Street restaurant row, direct trolley access to 69th Street |
| Wallingford-Swarthmore | $411,223 | Swarthmore College anchor, lowest turnover in the county, Wallingford-Swarthmore schools |
| Morton | $335,508 | Springfield School District access on a SEPTA rail line, smaller borough scale |
| Aston-Folsom | $303,063 | Penn-Delco School District, more suburban-tract housing stock, less walkable core |
| Woodlyn | $266,969 | Ridley School District, closer to the I-95 and river-town corridor |
| Springfield-Brookhaven | $240,722 | Further from a walkable downtown core, longer drive to a rail or trolley stop |
Read across that table and the trolley-and-walkability thesis holds up better than a school-district-only read would. Media and Wallingford-Swarthmore, both trolley-served and both built around a walkable center, sit well above Woodlyn and Springfield-Brookhaven, both of which lean more on driving than on rail or trolley access. Wayne and Radnor, priced well above every town in that table, layer a Main Line address and a private-college neighbor on top of the same transit advantage. The price isn't paying for square footage first. It's paying for a walkable downtown and a train or trolley platform within reach, with school district riding along as a correlated, not causal, third factor.
The Number Under The Number: Days On Market
There's a second signal buried in the county-wide data that a flat median price hides completely. Homes in Delaware County are taking longer to sell than they were a year ago, an average of 32 days on market in the three months ending April 2026, up from 24 days over the same window a year earlier. Sale volume slipped slightly too, with 476 homes sold that April compared to 478 the year before.
None of that shows up if you only look at the price, which barely moved. But days on market moving from 24 to 32 is a real shift, a quiet loosening of the seller's hand even while headline prices hold steady. For a buyer, that's useful information the median can't give you. It suggests more room for negotiation, more time to complete due diligence, and less pressure to waive contingencies than the flat price trend implies on its own. That extra room won't be evenly distributed. It will show up faster in the outlying, drive-to-everything towns than it will in Media or Swarthmore, where walkable inventory stays tight regardless of what the county-wide numbers say.
What This Means If You're Comparing Towns
The county median is not a target price and never was. It's an average of two markets that don't behave alike, sitting on top of a map that was largely drawn before 1920. If a walkable downtown, a trolley platform, and a college-town anchor matter to your daily life, that's what the higher price points in Media, Swarthmore, and the Main Line towns are actually buying, not just a better-rated school. If a quieter commute-by-car suburb with more house for the money matters more, the towns further from that original rail corridor are where the extra room, both in price and in negotiating leverage, is more likely to show up first.
A couple of questions worth asking before you compare towns
Does a lower price in a river town mean a lower-quality school district? Not necessarily. Ridley and Penn-Delco both offer solid K-12 programs. The price gap in Delaware County tracks walkability and transit history more closely than it tracks school quality alone, and a lower-priced town can still offer a strong school option.
Is the extra negotiating room from rising days on market showing up everywhere in the county? Unlikely evenly. Tight, walkable inventory in trolley-served boroughs tends to hold its pace even when the county-wide average slows down. The loosening is more likely to show up first in the towns further from that original corridor.
Comparing Delaware County towns on price alone will always be misleading, because the number is averaging over a divide that's been in place for more than a century.
