Assessment note: this home is assessed at $105,620 — well below the ~$176,870 its asking price implies at Montgomery County's common level ratio (30.8%). A sale near asking can invite a school-district assessment appeal that could raise the bill by roughly $2,135/year. Worth pricing in.

Recomputed from the county assessment ($105,620, 1996 base year) × current millage — portals typically reprint the recorded 2025 bill. Pennsylvania does not reassess on sale. Estimate only — verify with Montgomery County before relying on it. Learn more: PA property tax calculator · Common Level Ratio by county.
