Assessment note: this home is assessed at $140,090, well below the ~$187,442 its asking price implies at Montgomery County's common level ratio (29.8%). A sale near asking can invite a school-district assessment appeal that could raise the bill by roughly $1,419/year. Factor that into an offer.
Recomputed from the county assessment ($140,090, 1996 base year) × current millage. School millage is from the latest year certified by the Pennsylvania Department of Education (2025-26); districts adopt the next year's budgets each June, and we update when the state certifies the statewide file in the fall. Portals typically reprint the recorded 2025 bill. Pennsylvania does not reassess on sale. Estimate only. Verify with Montgomery County before relying on it.

Taxes use NookLocal's estimate at current millage rates, not the stale figure on the MLS. The default rate is the average 30-year rate as of July 2026; insurance is estimated at 0.35% of the price per year. Below 20% down, lenders usually add mortgage insurance, which this estimate doesn't include. Estimate only; verify before relying on it.
