Estimated property tax · per home, per year

Not enough history yet.

3
3 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 $186,441 a year off the tax roll. Read the tax figures with that in mind.

4136-40 Mitchell St is assessed at $13M but pays $18,214 a year — about 10% of the $182,152 it would owe at the statutory rate, because its new-construction value is abated.
