A mortgage recorded within 90 days after a deed on the same lot is counted as financing that purchase; any other is a refinance — our reading, not ACRIS's. ACRIS files a document against the first lot it names, so a blanket mortgage over several lots counts once. Since 2024-10-16.

around the block the property page's comps engine, seeded with this area's census tract and building classes

Class familyPeer setSalesMedian priceMedian $/sq ftMedian $/unit
O (7 lots of class O here)same census tract, 36 months •••• ••—

Each family is compared within its own class letter (a walk-up with walk-ups), on the comps ladder's tract rungs: 18 months, widening to 24 and 36 only when fewer than four sales qualify. Every quality filter applies. Highlighted rows are on this block.

A plan shows each sale, its price, buyer and seller, the lenders and the comparable sales.

Ownership who holds each lot now — the latest deed over a stale roll, the property page's rule

14 owners hold 18 lots · 3 hold more than one (7 lots) · the largest holds 3 (17%)

An owner group is the property page's: companies and people the identity graph joins, counted in buildings across the city. Individuals are counted here like everyone else; names are shown to signed-in readers, as on the property page. Brokers and agents are a separate domain and never appear.

A plan shows which lots, and why.

Open means what the property page means: an HPD litigation pending, a vacate order not rescinded (FDNY: not dismissed or rescinded), arrears in DOF's latest extract, a federal lien neither released nor lapsed and matched to an owner by name and address. Open violations are counted by the distress score's own rule, never as raw rows. Exemption removals are withheld while their reading is checked, as on the property page.

Development potential zoning and floor area from PLUTO; flood and evacuation zones; street widths

190,153 sq ft of on 7 lots · 1 (13,250 sq ft) · 1 (2 lots, 26,326 sq ft)

= the FAR that governs the building (residential, commercial or community facility, the property page's rule) × lot area − built floor area. None is given for an over-built lot, a mixed-use, special-purpose or split-zoned lot, or public land (parks, airports, utilities, transport, government sites, land owned by the city, state or federal government). Rough: no bonus, inclusionary or transfer rule, no overlay or district-boundary adjustment, no zoning-lot merger. A soft site is built to under 50% of that maximum. An assemblage candidate is a group of lots sharing tax-map edges where each neighbouring pair is under-built or held by one owner group.
