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 $15,398 a year off the tax roll. Read the tax figures with that in mind.
