Use the Brooklyn borough-block-lot number to connect the tax lot with ACRIS documents. Review the current deed, mortgages and satisfactions, liens, easements, and any condominium declaration or map that affects the parcel. For a property inherited through an estate or held by several relatives, identify the person authorized to sign and gather the court or trust documents early. A row house that shares a party wall or driveway may also have recorded agreements worth locating. Treat the online index as a starting point and ask the closing professional which instruments need certified copies or further examination.
Compare the building as it stands with records in DOB NOW and BIS. Search applications, permits, inspections, complaints, violations, and the certificate of occupancy where one exists. Pay special attention to finished cellar or basement space, an additional dwelling unit, a rear extension, deck, roof opening, or major plumbing and electrical work. HPD Online may add registration, complaint, violation, charge, litigation, or vacate-order information for covered housing. If the address is in a historic district, confirm whether exterior work also required Landmarks approval. Keep city findings separate from private association or tenant documents because each answers a different question.
Now compare the work attached to each sale path. A listing could call for record retrieval, an architect or contractor, repairs, tenant access, cleanout, staging, showings, and months of taxes, insurance, utilities, or common charges. An as-is offer can shift some renovation risk, but it does not erase disclosure, title, contract, or occupancy duties. Review deposit, inspection and termination clauses, proof of funds, cost allocations, closing extensions, possession, and the contents clause. Use the same known defects and open records in both estimates so convenience is not mistaken for a higher net.
