Mount Airy, Philadelphia Property Tax Appeal

Mount Airy has some of the largest homes in the price band — a median 1,620 square feet against a median assessment of $377,700 — and a sharp divide in housing character between its western and eastern halves. Where one ZIP contains two quite different markets, a per-square-foot comparison drawn from the wrong half is how an assessment goes astray.

How the BRT appeal works

In Mount Airy, the Board of Revision of Taxes (BRT) is the local review board for homeowners who want to challenge the value on a property tax notice. Your filing deadline is the first Monday in October — October 5, 2026 for tax year 2027, so the date printed on your notice controls when you need to act. The Property Assessment Appeal Application petition is filed with the Board of Revision of Taxes, while the Office of Property Assessment (OPA) remains the office that set the value you are challenging. The market-value argument is grounded in 72 P.S. § 5341.1 et seq. (Act 404 of 1939) — assessment appeals in cities of the first class, which means the packet should explain why local comparable sales, property condition, or assessment facts support a lower value. For homes around Philadelphia and neighborhoods such as West Mount Airy and East Mount Airy, the strongest appeal is specific to the assessor's own record and the neighborhood evidence rather than a generic tax complaint.

Mount Airy by the numbers

What the 2027 reassessment did in Mount Airy

The Office of Property Assessment revalues every property in the city each year. In ZIP 19119, 26.5% of single-family homes were assessed more than 10% higher for 2027 than they were for 2026 — against 21.4% citywide. Average assessed value across the ZIP moved from $413,939 to $438,668.

How many Mount Airy homes have a case

We ran 399 randomly selected 19119 homes through the same analysis behind the free estimate on this site — comparable sales and comparable assessments drawn from the city's own records. 22.3% cleared both thresholds we require before we will recommend an appeal: at least 10% over-assessed, and at least $150 a year of tax at stake. Among those, the median saving was $1,223 a year, against $741 citywide.

Those are estimates from public data on a sample of 399 homes, not a promise about yours. The Board of Revision of Taxes (BRT) decides every appeal on its own evidence. Enter your address to see the figure for your property.

What you get for $39.99

Start with a free estimate for your property. We use local assessment data to identify whether your value appears high enough to justify preparing an appeal packet, so you can decide before paying anything.

If the estimate shows a reasonable case, the $39.99 upgrade turns that analysis into a ready-to-file packet for your Mount Airy property tax appeal. The packet is built around the local filing path, the required petition form, comparable-property support, and plain-English filing notes that help you move from estimate to submission.

The fee is flat: no commission, no percentage of savings, and no surprise charge if your appeal lowers your tax bill. You keep any savings from the appeal, and you pay only for the document-preparation packet.

Mount Airy property tax appeal FAQ

West and East Mount Airy are very different. Will my comparables reflect that?

That is precisely what the analysis guards against. Comparable properties are drawn from the immediate area and banded by size and age, and a uniformity case is declined outright if the homes nearest yours do not support it — however favourable more distant properties might look.

When is the deadline to appeal a Mount Airy assessment?

The formal appeal to the Board of Revision of Taxes is due the first Monday in October — October 5, 2026 for the 2027 tax year. A separate, informal First Level Review with the Office of Property Assessment is due September 1, 2026. You can do both, and neither costs anything.

Do I need a lawyer to appeal in Mount Airy?

No. Both the First Level Review and the BRT appeal are free to file, and Philadelphia homeowners routinely handle these themselves. What most people lack is the evidence, which is what the $39.99 packet supplies: comparable sales and comparable assessments drawn from the city's own records.
