12 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 $114,156 a year off the tax roll. Read the tax figures with that in mind.
Who really pays — effective tax rate, one dot per home
800 N 21st St is assessed at $706K but pays $5,644 a year — about 57% of the $9,876 it would owe at the statutory rate, because its new-construction value is abated.
The block as an asset
Read like a financial asset, this block has lagged the Philadelphia market, compounding +4.6% a year against the city's 6.5%.
