Who really pays
Philadelphia charges every home the same 1.40% of its assessed value. Abatements and exemptions shrink what some homes are taxed on — here's this block:
- 462-66 Collom Stexemption0.00%$0/yr on $38K
- 470 Collom Sttax-abated new construction0.32%$454/yr on $144K
The starkest example: 470 Collom St is assessed at $144K but pays $454 a year — about 23% of the $2,009 it would owe at the full rate, because its new-construction value is abated for 10 years.
The block as an asset
Read like a financial asset, this block has beaten the Philadelphia market, compounding +7.8% a year against the city's 6.5%.
