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 $27,491 a year off the tax roll. Read the tax figures with that in mind.

4132 Tower St is assessed at $551K but pays $3,086 a year — about 40% of the $7,716 it would owe at the statutory rate, because its new-construction value is abated.
