The Radnor Township School Board approved its 2026-2027 budget with a 3.36 percent tax increase, raising the millage rate from about 15.8 to roughly 16.33 (Daily Times, May 29, 2026). Tax bills go out July 1, with a 2 percent discount if you pay by the end of August and a 10 percent penalty if you wait until the November-to-February window. For anyone buying or selling on this part of the Main Line, both the number and the dates matter.
What the Radnor Tax Increase Means for Your Wallet
A 3.36 percent increase is a moderate one, and it stays inside the state limit, so the district did not need a special exception this year. The bigger thing to mark on your calendar is the payment schedule. Pay by August 31 and you keep a 2 percent discount. Miss the early window and let it run past November and you face a 10 percent penalty. On a Radnor tax bill, those percentages add up to real dollars.
For a buyer, the timing of a closing can decide who pays which portion of the year’s taxes, so it is worth working through with your agent before you sign. For an owner, simply paying early protects the discount. Small moves like that are easy to miss and easy to get right once you know the dates.
Radnor Home Prices and the Tax Picture
Radnor sits at the higher end of the regional market, and its numbers move more than most because fewer homes sell each month. The median sale price in Radnor Township was about $1,250,000 as of March 2026, down 7.4 percent from a year earlier (Redfin, March 2026). In a small, high-priced market, a swing like that often reflects which homes happened to sell that month rather than a true drop in value, so read any single figure with that in mind.
It pays to understand how a market like Radnor behaves. Because so few homes change hands here each month, one unusual sale, a teardown lot or a multimillion-dollar estate, can pull the median up or down on its own. That is why a single month’s figure tells you less in Radnor than it would in a higher-volume town. New construction can stretch the picture too, since a brand-new home sitting on the market during its build period can lengthen the average time a listing takes to sell. The practical lesson for buyers and sellers is the same. Look at homes that truly compare to yours, not the county headline, and price or offer from there. On the Main Line, where each block carries its own value, that kind of careful read is worth more than any single statistic.
What stays constant is demand for this address. Radnor draws buyers who want proximity to the city, the train, and the colleges along the Main Line, and well-prepared homes still move quickly here. If you are weighing a sale, pricing to the current pool of buyers beats anchoring to last year’s peak. You can reach out and start the conversation through TheMcKnightTeam.com whenever you are ready.
What This Means for You
If you own in Radnor, pay your tax bill by August 31 to keep the discount, and mark the penalty date so it never sneaks up on you. If you are buying, sort out who covers which share of taxes at closing before you sign. If you are selling, price to today’s buyer and lean on Radnor’s steady demand. The tax increase is modest, but the payment calendar is where Main Line owners save or lose real money.
