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:
- 1219 N Allison Sttax-abated new construction0.14%$160/yr on $111K
- 1221 N Allison Sttax-abated new construction0.14%$160/yr on $111K
- 1223 N Allison Sttax-abated new construction0.14%$160/yr on $111K
- 1227 N Allison Sttax-abated new construction0.14%$160/yr on $111K
- 1211 N Allison Sttax-abated new construction0.22%$255/yr on $118K
- …and 14 more paying under the full rate — the gold-ringed bubbles in the makeup chart
The starkest example: 1211 N Allison St is assessed at $118K but pays $255 a year — about 15% of the $1,655 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 +8.7% a year against the city's 6.5%.

Rebased to 100 in 2016, like a stock against its index. $100 in the typical home here would be worth $251 today versus $201 across Philadelphia — this block outpaced the market.
