From the first showing to a confident decision.

Underwrite the actual tenancies and lawful income

For an occupied building, ask for a unit-by-unit schedule: occupants, current lease and renewals, riders, security deposit, stated legal and collected rent where relevant, concessions, arrears, included services, and claimed regulatory status. Request relevant notices, agreements, pending proceedings, and agency orders. Route legal interpretation through your attorney, and handle tenant records through authorized channels.

Rent control, rent stabilization, tax-benefit restrictions, and other tenant protections are different questions. HCR explains that rent regulation can involve the building’s history and tax-benefit programs, as well as tenant rights beyond the amount of rent. The present number of doors, the seller’s use of “market rate,” or the age of a lease does not answer every status question. HCR: Rent Stabilization and Rent Control.

Use the HCR building search as a lead, then obtain apartment-specific evidence. The NYC Rent Guidelines Board explains that buildings on HCR’s list have filed records at least once since 1984 and may contain regulated apartments; listing the building does not establish that every apartment is regulated. Conversely, an online search is not a reason to disregard conflicting evidence. NYC Rent Guidelines Board: building-list limitations.

Prospective buyers should not assume they can retrieve unrestricted private rent histories directly. HCR describes access generally for the tenant, owner of record, or authorized representative, and provides an owner route to certified registered-apartment reports. Ask the seller to supply the appropriate records or authorization through counsel. Have counsel reconcile registrations with leases, rent ledgers, benefit history, orders, and any claimed exemption or deregulation basis. HCR: records access; HCR records-request form.

Good Cause Eviction is a separate review even for apartments described as unregulated; coverage and exemptions need fact-specific analysis. HPD: Good Cause Eviction.

Budget rule: use documented, legally supportable income and realistic vacancy/repair assumptions. If your plan requires vacant possession or personal occupancy, have your attorney establish how that outcome can lawfully be delivered and reflected in the contract. Do not assume a sale ends an existing tenancy.

Inspect the building behind the finishes

Commission an independent inspection with access to every relevant floor and system. Ask in advance about roof access, occupied units, locked mechanical rooms, crawlspaces, rear elevations, and storage that conceals walls. Have the report name inaccessible areas and recommended specialists. New York’s inspection standards are not technically exhaustive; they do not require identification of concealed defects, environmental hazards, or every code violation. NYS Department of State: home-inspection standards.

Use this focused tour and inspection agenda:

Ask for written specialist scopes where the first inspection identifies uncertainty. A roofing estimate, masonry investigation, structural opinion, plumbing/sewer review, or electrical assessment should answer a defined question. Distinguish routine maintenance from urgent repairs and long-term replacement. Cosmetic renovation should not be used to infer that concealed systems were replaced.

Request warranties, service contracts, paid invoices, and any transferable guarantees. Match invoices to addresses and work scopes. Ask your professional whether the records establish the work claimed or merely show that a contractor was paid.

• Envelope: roof drainage, flashing, parapets, coping, chimneys, skylights, windows, masonry joints, visible cracking, patched areas, and the junction between the original house and extensions.
• Water: staining, peeling finishes, persistent odors, efflorescence, sump equipment, low entry points, yard slope, area drains, and evidence of repeated lower-level repairs. Ask when, why, and how past water entry was addressed.
• Structure: changes in floor slope, movement around openings, altered bearing walls, beams/posts, connections, and visible party-wall conditions. Refer unexplained distress or major past alterations to an engineer.
• Systems: documented age and service history of heating/cooling and hot-water equipment; electrical service and panels; visible piping; gas status; venting; sewer/service-line concerns; and whether proposed upgrades fit available capacity.
• Safety and use: stairs, railings, exits, smoke/carbon-monoxide protection, fire separation where relevant, and the fit between the actual arrangement and the intended occupancy.

Assign responsibilities from tour to contract

Build a small team with explicit assignments rather than asking every professional the same broad question.

Suggested sequence:

Use one issues register: item; evidence; responsible person; deadline; cost/timing effect; proposed resolution; document confirming resolution. This keeps an encouraging verbal update from being mistaken for a completed task.

• Before the first serious tour: confirm address/BBL and district status; screen DOB, HPD, taxes, and initial occupancy information; write down your intended use.
• During tours: see every available level; record inaccessible areas; compare the floor plan with the actual layout; assemble specific questions about water, systems, work history, and occupants.
• Before finalizing an offer strategy: assess financing and insurance fit, request the seller document package, and identify any issue that changes value or feasibility.
• Before signing a binding contract: coordinate counsel’s timing for inspections, title/tenancy review, essential archived records, renovation feasibility, disclosures, and protection for any unresolved matter. The negotiated contract governs contingencies and deadlines; an informal expectation is not a substitute.
• Between contract and closing: track promised corrective work and agency evidence; satisfy lender/insurer conditions; update searches and financial estimates as advised; arrange a final walkthrough and document transfer.
• At handover and immediately after closing: receive keys, records, permits, warranties, service information, and tenancy/security-deposit documentation as applicable; arrange required account and registration updates. DEP requires the new owner to notify it of a sale using its customer-registration process. DEP forms and ownership transfer.

Buyer priorities: a finite decision checklist

Complete these twelve items for the property under consideration. An unresolved answer should be visible to the buyer, attorney, lender, or relevant specialist before the next commitment.

Key cautions: an online “no result” is not a certification; an old house is not exempt from every approval; a tax-unit count is not a legal-use ruling; a permit is not a final sign-off; a rental listing is not a regulatory determination; zoning capacity is not LPC approval; an absence of recent water damage is not a flood guarantee; and prior-owner work can still require correction. Keep each question attached to the source and professional capable of answering it.

• The address, BBL, BIN, included parcels, and form of ownership match the proposed contract.
• LPC designation boundaries and the house’s status have been checked in official records.
• The seller’s title/authority and material title exceptions have been reviewed by counsel and the title professional.
• The survey and legal descriptions support the space, access, and improvements being represented.
• The lawful use and dwelling-unit count have been reconciled floor by floor, including lower levels.
• BIS, DOB NOW, and necessary archived records have been reviewed, with a resolution plan for material open items.
• HPD registration, violations, orders, and recurring conditions have been evaluated where applicable.
• Existing occupants, leases, rent regulation, other tenant protections, deposits, income, and possession plans have received appropriate review.
• The independent physical inspection is complete; material exclusions and recommended specialist follow-ups have been addressed.
• Lead/asbestos/environmental questions and relevant seller records have been reviewed for the intended use and work.
• Address-specific flood research, lender requirements, and written insurance proposals support the ownership plan.
• Acquisition, operating, repair, and capital budgets use actual records/quotes, and the contract addresses remaining material uncertainties.
