Who really pays — each home's tax bill as a share of its value
Philadelphia charges every home the same 1.40% of its assessed value. On this block, 13 of 38 homes pay that full rate — and 25 pay less, because abatements and exemptions shrink the taxed value. Each dot is one home; the further left, the less of its value it pays. Hover a dot for the house.
The starkest example: 1819 W Thompson St is assessed at $693K but pays $0 a year — about 0% of the $9,695 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 +8.9% 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 $256 today versus $201 across Philadelphia — this block outpaced the market.
Return is from assessed-value history (a proxy for market price, lumpy in reassessment years); rental yield is estimated from ACS area rents. Informational only, not investment advice.
