1
1 property 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 $2,080 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:

9 homes pay the full 1.40%2 pay less
$454pays now $2,009at the full rate

The starkest example: 470 Collom St is assessed at $144K but pays $454 a year — about 23% of the $2,009 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 +7.8% a year against the city's 6.5%.
