32
32 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 $304,196 a year off the tax roll. Read the tax figures with that in mind.
Who really pays — effective tax rate, one dot per home
817 N 20th St is assessed at $3.0M but pays $4,138 a year — about 10% of the $41,384 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 +3.2% a year against the city's 6.5%.
Indexed performance · this block vs. the Philadelphia market
