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:
- 4925 Catharine Sttax-abated new construction0.70%$5,109/yr on $726K
- 4927 Catharine Sttax-abated new construction0.94%$7,317/yr on $774K
- 4907 Catharine Stexemption0.98%$3,220/yr on $330K
- 4917 Catharine Stexemption0.98%$3,263/yr on $333K
- 4923 Catharine Stexemption0.98%$3,263/yr on $333K
- …and 9 more paying under the full rate — the gold-ringed bubbles in the makeup chart
The starkest example: 4927 Catharine St is assessed at $774K but pays $7,317 a year — about 68% of the $10,840 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 +7.9% a year against the city's 6.5%.
Indexed performance · this block vs. the Philadelphia market
Rebased to 100 in 2016, like a stock against its index. $100 in the typical home here would be worth $231 today versus $201 across Philadelphia — this block outpaced the market.
