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:
- 1221-27 N 17th Sttax-abated new construction0.00%$0/yr on $2.0M
- 1229 N 17th Stexemption0.00%$0/yr on $19K
- 1249 N 17th Sttax-abated new construction0.14%$513/yr on $367K
- 1249 N 17th Sttax-abated new construction0.14%$557/yr on $398K
- 1233 N 17th Sttax-abated new construction0.28%$1,783/yr on $637K
- …and 4 more paying under the full rate — the gold-ringed bubbles in the makeup chart
The starkest example: 1221-27 N 17th St is assessed at $2.0M but pays $0 a year — about 0% of the $28,244 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 tracked the Philadelphia market, compounding +6.4% a year against the city's 6.5%.
