The makeup of the block

28
28 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 $100,892 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:

13 homes pay the full 1.40%48 pay less
$1,575pays now $9,580at the full rate

The starkest example: 765 S 12th St is assessed at $684K but pays $1,575 a year — about 16% of the $9,580 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 lagged the Philadelphia market, compounding +3.6% a year against the city's 6.5%.
