An off-market NYC commercial deal has none of the outside checks a public marketing process provides. No investment banker has vetted a CIM, no competitive bidding sets a clearing price, and no broker network is checking the rent roll on its own. The buyer's verification is the only verification. The good news is that NYC puts more property data in the public record (ACRIS, PLUTO, DOB, HPD, DHCR, ECB, and other city systems) than almost any other commercial real estate market in the country. Careful buyers and their brokers use those systems to check every material representation before committing capital. This is the verification framework Robert Khodadadian and Skyline Properties have used across $976M+ of closed NYC transactions.
ACRIS: verifying ownership and chain of title
ACRIS (the NYC Automated City Register Information System) is where the city records deeds, mortgages, mortgage assignments, releases, and most other instruments affecting real property in NYC. You can research almost any question about ownership history, capital stack, and chain of title there yourself.
On every off-market target, pull the complete ACRIS file: every deed going back at least 10–20 years, every mortgage and assignment, every release, every memorandum of lease, every judgment or lis pendens. Look for patterns. Several transfers in quick succession, mortgages that were never released, or unexplained transfers of partial interests all raise questions the seller may not have mentioned.
ACRIS also tells you whether the selling entity actually owns the property, whether the person signing the LOI has authority, and whether the debt the seller describes matches what's on file. Plenty of off-market deals die on something found in ACRIS. Careful buyers find it before the LOI instead of at title clearance.
PLUTO and the NYC Zoning Map: verifying lot, zoning, and FAR
PLUTO (Primary Land Use Tax Lot Output) is the Department of City Planning's dataset for every tax lot in the city. With the NYC Zoning Map, it confirms lot size and dimensions, zoning district, FAR, special purpose districts, inclusionary housing eligibility, landmark status, and any historic district overlay. Every development site analysis starts with PLUTO, and any plan to redevelop or reposition an existing building should be checked against it.
PLUTO is generally reliable but sometimes disagrees with measurements on the ground. A current ALTA survey confirms the actual lot dimensions and any encroachments. On development sites and conversion candidates, PLUTO and the zoning analysis come first.
DOB: Certificate of Occupancy, permits, and violations
The Department of Buildings' public portals, BIS (Building Information Search) and DOB NOW, show the Certificate of Occupancy, permit history, open work orders, ECB (Environmental Control Board) violations, and stop-work orders. Nearly every serious physical-condition red flag in NYC shows up in DOB records.
Check that the Certificate of Occupancy matches how the building is actually used today. A residential rental building with a commercial C of O carries exposure. A building with an outdated C of O may not be legally operable for its current use. C of O mismatches are common in older NYC buildings and often cost real money to fix.
Pull every open permit and every outstanding violation. ECB violations carry fines and have to be cleared before certain transactions (and certain types of title insurance). An open stop-work order makes a building close to unfinanceable until it's lifted.
HPD: for residential buildings
The NYC Department of Housing Preservation and Development (HPD) registers residential properties, tracks housing-code violations, and handles tenant complaints. For any residential or mixed-use property, HPD records show registration status (mandatory for buildings with three or more units), open violations (Class A through Class C, in rising order of severity), and the history of complaints.
A building with a lot of open HPD violations carries financial exposure and can bring tenant litigation. Out-of-town buyers often skip HPD. Experienced NYC buyers pull it on every residential and mixed-use target.
DHCR: rent stabilization verification
The New York State Division of Housing and Community Renewal (DHCR) keeps the registry of rent-stabilized units in NYC. Every stabilized unit must be registered each year with its legal regulated rent, any preferential rent, and the tenant's name. Owners file the annual registrations, and tenants can dispute the registered rent.
On any rent-stabilized or mixed NYC multifamily acquisition, request the DHCR registration history for every unit, going back at least 4–10 years. Confirm the registrations are current, that the legal regulated rents match the rent roll, and that no overcharge or rent reduction case is pending.
The DHCR findings that most often re-trade off-market deals: a unit registered as stabilized but charging free-market rent (possible overcharge exposure); a unit registered at a much lower rent than the rent roll shows (possibly a preferential rent that drops back at renewal); registrations missing for recent years (penalties and tenant claims); and DHCR cases the seller never disclosed.
Since HSTPA, DHCR diligence carries more weight than it ever has. Skyline Properties requires full DHCR verification on every stabilized or mixed-roll multifamily acquisition.
Third-party physical verification: engineering, environmental, survey
Public records confirm legal and regulatory status. Third-party reports confirm what's physically there. On any off-market acquisition above $5–10M, the standard third-party package includes:
- ALTA survey: confirms lot dimensions, encroachments, easements, and boundary conditions
- Phase I environmental site assessment: identifies recognized environmental conditions; required by most lenders
- Phase II environmental (where the Phase I finds RECs): soil and groundwater sampling
- Structural engineering inspection: facade, foundation, roof, structural systems
- MEP inspection: mechanical, electrical, and plumbing systems and their remaining useful life
- Roof inspection: on its own or as part of the engineering report
- Asbestos and lead-based paint surveys on pre-1980 buildings
- Local Law 11 facade inspection report (FISP filing): current and prior cycles
Tenant verification: interviews and estoppels
Public records and seller representations describe the rent roll on paper. Tenant interviews and estoppels tell you whether it holds up. In office and retail buildings, interviewing tenants during diligence (usually done by the buyer's leasing or asset management team, with the seller's permission) tells you who plans to stay, what they complain about, and lease-language details the rent roll leaves out.
Tenant estoppels are written certifications from each tenant confirming the lease terms, that rent is paid current, and that there are no defaults or pending claims. They are a standard PSA requirement and usually a closing condition. A tenant who returns an estoppel with exceptions, or won't sign one, is pointing at a problem the seller may have played down.
FOIL requests: for records not in public databases
The New York Freedom of Information Law (FOIL) gives public access to government records you can't get through the web portals. On specific issues, such as pending DOB enforcement, environmental cleanup records, or water meter history, a FOIL request can turn up information that ACRIS, PLUTO, DOB BIS, and HPD don't show.
FOIL is slow (responses usually take 20–30 business days, sometimes longer), so it's used selectively, when the portals don't answer the question. Experienced NYC real estate counsel regularly build FOIL requests into diligence when a specific exposure has to be run down.
Cross-checking: how problems actually get found
Most real findings come from cross-checking one source against another. The rent roll shows $4.2M of annual rent and the operating statement shows $3.9M of effective gross income. Why the difference? The seller's pro forma carries $400K of property tax and the actual bill from the NYC Department of Finance is $510K. Where's the gap? The seller says there are no open violations and DOB BIS shows four open ECB violations. What's the explanation?
Check every material number in the seller's package against a public record or a third-party source. A discrepancy isn't necessarily fatal. There may be an innocent explanation. But it has to be raised and explained before the LOI, not discovered after closing. Skyline Properties builds a cross-check matrix on every institutional off-market target.
NYC Department of Finance: tax assessment verification
The NYC Department of Finance keeps public property tax records for every tax lot in the city. The Notice of Property Value (NOPV) and the annual tax bill are online for every block and lot. Together they show assessed value, market value, tax class, the current bill, any abatements or exemptions, and where the transitional assessment sits in its phase-in.
Checking the tax record against the seller's operating statement takes little time and often pays off. What we typically find: tax expense on the operating statement lower than the actual DOF bill (so expenses are understated); abatements close to expiring with no step-down or post-abatement tax built into the underwriting; transitional assessment phase-ins that will push taxes up materially but haven't hit the current bill yet; and recent reassessments that haven't reached the operating statement.
On every institutional acquisition, Skyline Properties checks the DOF record against the seller's representations and models the tax bill several years forward for the underwriting.
Using existing third-party reports
Many NYC commercial properties already have recent third-party reports that the seller ordered for a past refinancing, a past marketing effort, or insurance: Phase I environmental reports, structural reports, FISP filings, lender appraisals, and others. Where they exist, the consultant can often extend reliance to a new buyer for a modest fee, and they save a lot of verification work.
Ask for every prior third-party report as part of the pre-LOI information package. Even if full reliance isn't available, the old reports help scope the new diligence and often reveal issues the seller wouldn't have raised on their own.
Frequently asked questions
- Is ACRIS data reliable for NYC commercial real estate verification?
- ACRIS is generally reliable for what it records: deeds, mortgages, assignments, releases. The recording date and the content of a recorded instrument are authoritative. ACRIS doesn't capture every transaction (entity-level transfers and off-record agreements won't appear), and it doesn't interpret documents; that takes a lawyer. For chain of title and capital stack, start with ACRIS and back it up with a full title search.
- How do I verify a NYC rent-stabilized rent roll?
- Request the DHCR registration history for every unit, going back at least 4–10 years. Confirm a registration was filed every year, that the legal regulated rents match the rent roll, that any preferential rents are documented, and that no overcharge or rent reduction case is pending on any unit. The usual findings are missing registration years, registered rents that don't match what's being charged, and open tenant cases.
- What if I can't access the property for physical inspection?
- Most off-market NYC commercial sellers allow physical inspection during diligence, usually after the LOI and a confidentiality agreement are signed, on a reasonable schedule. A seller who refuses inspection is telling you something. Never close on an NYC commercial property without a full physical inspection by qualified engineers and environmental consultants.
- How long does NYC commercial real estate verification take?
- An experienced team can finish public-records verification (ACRIS, PLUTO, DOB, HPD, DHCR) in 5–10 business days. Third-party physical reports (engineering, environmental, survey) usually take 2–4 weeks. Tenant estoppels and interviews depend on the tenants, but they generally come in within the 30–60 day diligence period. On a typical NYC commercial deal, verification runs at the same time as the PSA negotiation.
- Should I use a broker to help verify off-market property information?
- Yes. Experienced NYC commercial brokers work in all the relevant public-records systems daily and have verification routines built over many transactions. Skyline Properties runs structured verification on every off-market mandate, so findings come out before the LOI instead of at closing.
