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 $25,906 a year off the tax roll. Read the tax figures with that in mind.

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, 30 of 48 homes pay that full rate — and 18 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.

$884pays now $2,994at the full rate

The starkest example: 4265 Castor Ave is assessed at $214K but pays $884 a year — about 30% of the $2,994 it would owe at the full rate, because its new-construction value is abated for 10 years.

The block as an asset
