Know Exactly What You Are Buying
Independent due diligence investigations for buyers and sellers of New York multi-family and mixed-use properties. We examine the building's full regulatory and litigation record so the risks show up at the negotiating table, not years after closing.

Our Approach to Due Diligence
New York's rent control and rent stabilization laws govern much of the city's multi-family housing stock. A building can look sound on the rent roll and still carry restrictions, overcharge exposure, and occupancy problems that never appear in the marketing package.
We work through the building's record and give you a written report you can act on. Where we find a problem, we tell you the potential liability, whether it can be cured, and how it should be handled in the contract of sale. Where the record is clean, we say that too. Sellers use the same process in reverse, surfacing the questions a well-informed buyer will ask so there are no surprises mid-negotiation.

What a Butnick Law Report Uncovers
Rent Regulation & Registration Analysis
We compare the rents on the deal sheet and in the offering materials against the rents registered with public authorities, identify existing rent restrictions, and flag overcharge complaints, prior judgments, and other issues that can limit what you can do with the building.
Litigation History & Current Legal Health
Beyond entered judgments, we identify pending cases, so you see both the building's history and its condition today, including occupancies, disputes, and liabilities that a new owner would inherit on day one.
Occupancy, Use & Violation Review
We examine apartment registrations, certificates of occupancy, and building use against the actual record, identifying illegal occupancies, incorrect registrations, and open violations that carry cure costs or ongoing liability.
Contract Recommendations You Can Use
Every report closes with specific recommendations for the contract of sale, including seller representations, document preservation, and cooperation provisions covering any proceeding a buyer may need to continue after closing.
Agencies and Repositories We Search
“Where a name appears in building records but not in government filings, or where the two conflict, we treat that as the beginning of the investigation rather than the end of it.”
Due Diligence FAQs
Findings that carry a real cost, whether an overcharge exposure, an illegal occupancy, or an open violation with a cure obligation, are quantifiable. We give you the number and the supporting record so you can decide whether to renegotiate price, require a seller cure before closing, or walk away.
