The makeup of the block

Every home, plotted by size and assessed value — press play and watch the block reprice from 2016 to 2027. One bubble per house (area = lot size), colored by who owns it; a gold ring marks tax-abated new construction. Click a bubble for its report.

15
15 properties on this block carry a tax abatement or major exemption. New construction and gut rehabs get the improvement value exempted for up to 10 years, so their tax bills sit far below their real value — block-wide, exemptions keep about $30,255 a year off the tax roll. Read the tax figures with that in mind.

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:

21 homes pay the full 1.40%23 pay less
$743pays now $2,244at the full rate

The starkest example: 803 S Allison St is assessed at $160K but pays $743 a year — about 33% of the $2,244 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%.
