Living on the Main Line: Real Estate Guide
The Main Line is the string of communities west of Philadelphia along the rail corridor now served by SEPTA’s Paoli/Thorndale Line, spread across townships such as Lower Merion, Haverford, Radnor, Tredyffrin and Easttown in Montgomery, Delaware and Chester counties. Housing runs from apartments and condos near the stations to twins, townhomes and single family homes on a wide range of lot sizes. Max Karasick, a Compass agent licensed in Pennsylvania and New Jersey, helps buyers, sellers and renters compare these townships on taxes, transit access and housing stock before they commit to a street.
The week here runs on the train: a morning walk to a Paoli/Thorndale Line station, an errand on Lancaster Avenue on the way back and a house with a yard at the end of it. The trade is a commute for more space, plus a tax bill set by township and county lines that a mailing address does not show.
Who It Fits
Buyers who want a single family home with a yard, a driveway and a train station within reach of Center City offices
Buyers or renters who want an apartment or condo near a commercial district
Buyers who want an older house and accept historic district review on exterior work where it applies
Commuters who want Regional Rail, the M line or Amtrak Keystone Service at Ardmore
Housing Stock
The Main Line is not a municipality. It is a set of villages and postal areas whose names often do not match the township lines that decide taxes and services. Lower Merion Township lists Ardmore, Bryn Mawr, Gladwyne, Haverford, Rosemont, Villanova and Wynnewood among its villages. Radnor Township lists Wayne, St. Davids, Rosemont, Villanova and Bryn Mawr among its unincorporated communities. Tredyffrin Township counts Wayne, Berwyn, Paoli and Devon among its postal regions, and Easttown Township covers Devon and Berwyn. That overlap is why a Bryn Mawr or Wayne address can sit in more than one township.
The housing follows the rail line and the commercial corridors. Near the stations and along Lancaster Avenue there are apartment buildings, condos, twins and mixed use buildings with apartments over shops, including in Lower Merion’s Ardmore Commercial Historic District, established in 1993. Farther out, detached homes on larger lots are more common.
Historic rules are local. Lower Merion’s Historical Architectural Review Board reviews exterior work, new construction, demolition and signs in the township’s local historic districts. Radnor’s Historic and Architectural Review Board covers the North Wayne Historic District. Condo buyers should budget for monthly association fees and read the association’s reserves and rules.
Prices and Rents
Prices on the Main Line vary more by township, school district and distance to a station than by the village name on the listing. Lot size, age, condition, historic district status and property type all move value.
Max shares current Bright MLS figures for Main Line on request, including median sale price and days on market, pulled for the specific property type a client is weighing.
Compare the cost of the whole week: price, combined taxes, the commute and upkeep on a bigger lot. Whether a large yard is a need or a want usually decides which townships stay on the list.
Getting Around
SEPTA’s Paoli/Thorndale Line is the spine of the Main Line. The timetable effective October 18, 2026 lists stops including Overbrook, Merion, Narberth, Wynnewood, Ardmore, Haverford, Bryn Mawr, Rosemont, Villanova, Radnor, St. Davids, Wayne, Strafford, Devon, Berwyn, Daylesford and Paoli, continuing to William H. Gray III 30th Street Station, Suburban Station and Jefferson Station in Center City. Amtrak’s Keystone Service also stops at Ardmore, where Amtrak and SEPTA marked the completion of a rebuilt station in April 2026.
SEPTA Metro’s M line, formerly the Norristown High Speed Line, runs between 69th Street Transit Center and Norristown Transit Center with stops that include Ardmore Junction, Ardmore Avenue, Haverford, Bryn Mawr, Garrett Hill, Villanova, Radnor and County Line. SEPTA lists shuttle buses in place of trains between Norristown Transit Center and Bridgeport through December 19, 2026. On the road, Lancaster Avenue is the main surface route linking the commercial districts.
Taxes and Costs
Pennsylvania real estate tax is three bills, not one: county, township and school district, each with its own millage rate. Haverford Township’s finance page explains the math: assessed value multiplied by the millage rate in effect, divided by 1,000. Assessments are set by the county, so totals can differ sharply across a township or county line.
Radnor notes that owners pay the township, the Radnor Township School District and Delaware County on different due dates, and Lower Merion bills the school district tax on a July to June fiscal year. A homestead exclusion can lower the school bill on a primary residence. Montgomery County’s Board of Assessment Appeals sets values in Lower Merion, while Delaware County and Chester County handle Haverford, Radnor, Tredyffrin and Easttown.
Pennsylvania also charges a realty transfer tax on a sale. The Department of Revenue lists the state portion at 1 percent of the value of the real estate (as of October 2026), and local jurisdictions add their own share, which varies by municipality and school district. Buyers and sellers usually agree in the contract on how to split it. For a comparison with the city, see the Philadelphia transfer tax guide.
Schools
Public schools on the Main Line are run by separate districts, including the Lower Merion School District, the Haverford Township School District, the Radnor Township School District and the Tredyffrin/Easttown School District; buyers should confirm the district for any address and review school information directly with that district.
Working With Max on the Main Line
For sellers, pricing starts with recent closed sales in the same township and school district, adjusted for lot, condition and distance to the station, then moves into a listing campaign with professional photography, Compass marketing and a showing plan built around the property. Owners can start with a home valuation request or learn more on the selling page.
For buyers, Max builds the search around the township and school district, the distance to a Paoli/Thorndale Line or M line stop, the full tax picture and any local historic district. Start on the buying page, find rental help on the renting page or reach Max through the contact page.

FAQ
Is the Main Line a town?
No. The Main Line is an informal name for communities west of Philadelphia along the Paoli/Thorndale Line corridor. Taxes, zoning and services come from the township and county where a property sits.
Can you commute from the Main Line to Center City by train?
Yes. SEPTA’s Paoli/Thorndale Line runs from Main Line stations such as Ardmore, Bryn Mawr and Wayne to 30th Street, Suburban and Jefferson Stations, and Amtrak’s Keystone Service stops at Ardmore.
How are Main Line property taxes calculated?
Each Main Line property pays separate county, township and school district taxes. Each bill is the assessed value multiplied by that body’s millage rate and divided by 1,000, so check each body’s page for current rates.
Why doesn’t a Main Line mailing address tell you the township?
Postal names such as Bryn Mawr and Wayne cross township lines. Lower Merion and Radnor both list Bryn Mawr as one of their communities. Max confirms the township and school district for every address before an offer.
