Which Narberth you are actually in
Narberth Borough is half a square mile, incorporated in 1895, and completely surrounded by Lower Merion Township. About 4,492 people and 2,016 housing units at the 2020 count. It runs a council-manager government with its own mayor and a seven-member council, its own recreation, its own business district.
What it does not run is a school district. Narberth is in Lower Merion School District, the same as the township wrapped around it. So the school portion of the bill, which is most of the bill, does not change when you cross the line. Everything municipal does.
The station is on the same short list. Narberth station at 211 Elmwood Avenue is on the Paoli/Thorndale Line, 111 daily parking spaces, rebuilt around 1980 under an agreement between SEPTA and the borough council. Peak runs on the July 5, 2026 timetable reach Suburban Station in 21 to 24 minutes, which is the shortest ride of any town on this site apart from Merion.
The bill that follows
A Narberth parcel carries 52.319 mills for 2026: 9.865 borough, 5.952 county and community college, and 36.5017 Lower Merion School District. A Lower Merion Township parcel carries 47.273, because its municipal rate is 4.819.
So the borough rate is more than double the township’s, and that is the price of running a half-square-mile municipality with its own everything. The school half, 36.5017 mills, is identical on both sides.
Assessments are 1996-base and the common level ratio factor is 3.36, so assessed value runs near market divided by 3.36. On the $825,000 July median for the Narberth 19072 area, that is roughly $245,500 assessed, times 52.319 mills, near $12,800 a year before homestead relief. Estimate, and your parcel’s own assessment is what actually gets billed.
Two costs sit outside the millage and both moved for 2026. The borough raised its earned income tax from 0.75% to 1.00%, effective January 1, 2026, under Ordinance 1067 adopted at a special meeting on December 1, 2025, with the stated goal of building up the capital fund. Narberth is one of three Montgomery County municipalities where the municipality takes the entire 1% and the school district takes none; the borough also carries a $12,000 low-income exemption, the highest in the county. Lower Merion Township, on the other side of the line, levies no earned income tax at all. On $150,000 of earned income that is $1,500 a year against nothing.
And solid waste. The 2026 budget adopted December 18, 2025 moved the standard rate from $204 per living unit to $250, with condominium units billed at $250 each and other classes rising as well. It is not in your mortgage escrow, so put it in your own arithmetic.
Transfer tax stays at 2.000%, the same as at every Montgomery County address.
The houses, and what an appraiser asks
The 2020 count found 2,016 housing units on half a square mile, and no dependable published breakdown of their age or construction exists, so this page will not describe them. What the sold data says, with its geography attached: the Narberth 19072 area posted a $825,000 median on 19 sales in July 2026, sitting 40 days against 21 a year earlier. That ZIP reaches past the borough into the township, so 19 closings is a ZIP figure and not a borough one.
The appraisal question in a place this small is the comparable sales. Nineteen closings across a wider ZIP means a thin set inside the borough itself, and an appraiser will cross into Lower Merion Township for comps without hesitating. That is normal and it supports value fine. It just means the comparable house may sit on a different municipal bill than the one you are buying.
What a lender will ask about here
The parcel, so the escrow is built on the borough’s 52.319 mills. Then the seller’s current tax bill, since the borough and school portions arrive on separate calendars and the escrow has to hold both.
Price is not the constraint. At the area median with 20% down the loan is $660,000, against a 2026 conforming limit of $832,750 for a one-unit home in Montgomery County; the FHA limit here is $630,200. Jumbo underwriting starts near a $1,040,900 price at 20% down, so it enters this conversation only at the top of the borough’s range or on a very small down payment.
Two things worth doing in the first week. File a Residency Certification Form with your employer so the earned income tax routes to the right six-digit PSD code from your first pay period, since the borough’s 1.00% is new as of January. And ask about homestead relief, which comes off assessed value on the school portion, is applied for at the county assessment office, and waits a year if you close after March 1. Lower Merion School District’s published relief was $417 per approved homestead for 2025-26.

Bala Cynwyd and Wynnewood are township addresses in the same school district with no earned income tax. Bryn Mawr is further out the same line and into two counties.
What to do next
Have the address, the price, and whether the parcel is borough or township. Send it along and a licensed Pennsylvania mortgage lender calls you back, usually the same working day, and by the end of the next working day at the outside. What gets approved, and on what terms, is that lender’s call after reading the file. Half a square mile is small enough that the difference lands on a single street, so get the answer in writing before the offer.
