Co-op Due Diligence: Reading Financials and Board Minutes

Co-op due diligence means checking the building's money and condition before you sign, because as a shareholder you share its debts and repair bills. Start with the last two years of audited financial statements and board minutes, then check the underlying mortgage, reserves, pending assessments and the building's city records.

Your attorney reviews these documents, but you should read them too. You will live with the answers, and the checklist at the end of this page keeps track of what you have covered.

What to ask for

Once your offer is accepted, your attorney requests the due diligence package from the managing agent. It usually includes:

• The offering plan and amendments, proprietary lease, bylaws and house rules.
• The last two or three years of audited financial statements.
• Board minutes (some buildings only let attorneys read them at the managing agent's office).
• A managing agent questionnaire covering sublets, flip tax, assessments, litigation and the underlying mortgage.
• The current maintenance for the unit and the number of shares allocated to it.

How to read the financial statements

You don't need to be an accountant. Focus on a few questions and compare year to year.

The underlying mortgage

Many co-op corporations carry a mortgage on the whole building, separate from your share loan. Some are interest-only or only partly paid down, leaving a large balance due at maturity. When it matures, the board must refinance, and if rates are higher, maintenance goes up for everyone. Look for:

• The maturity date and how much is due then.
• The interest rate and whether it is fixed.
• Any line of credit and how much has been drawn.
• Prepayment penalties that limit when the board can refinance.

You can also see the building's recorded mortgages, assignments and satisfactions in ACRIS against the building's lot (see ACRIS mortgages and liens).

Tax benefits that could end

Check whether the building receives the co-op/condo abatement. The Department of Finance says the board applies for the whole development, and units qualify only if they are the owner's primary residence. Ask whether the building has another tax benefit such as J-51 or 421-a that is ending, which can raise taxes passed through in maintenance. Use the abatement estimator and the 421-a and J-51 expiry calculator.

What to look for in board minutes

Minutes show what the board is worried about before it reaches the financial statements. Read for:

• Capital projects: roof, boiler, windows, elevators, facade, gas piping, electrical upgrades.
• Money talk: assessments, maintenance increases, refinancing, drawing on the line of credit.
• Disputes: lawsuits, insurance claims, conflicts with commercial tenants or neighbors.
• Recurring complaints: leaks, heat, pests, noise; repeated items suggest an unsolved problem.
• Policy changes: sublet rules, pet rules, renovation rules, a new or higher flip tax.

Upcoming capital needs from city laws

Local Law 97

Local Law 97 sets carbon emissions limits for buildings over 25,000 gross square feet (and certain groups of buildings on one lot over 50,000). Limits began in 2024 and get stricter in 2030, and covered buildings file emissions reports by May 1 each year. A building over its limit faces fines or must pay for upgrades. Ask whether the building filed its report, whether it complies now and for 2030, and what it plans to spend. Estimate exposure with the LL97 fine estimator.

Facade inspections (FISP / Local Law 11)

Buildings taller than six stories must file a facade report every cycle. In Cycle 10, the filing window depends on the last digit of the block number:

Ask for the status of the last facade report (safe, safe with a repair and maintenance program, or unsafe) and the cost of any repairs it called for. Check timing with the facade cycle checker and the gas piping cycle with the LL152 checker.

Check the building's public record on Roofy

Search the address on Roofy. Look for open HPD Class C violations, DOB and ECB violations with unpaid penalties, recent permits for large projects, and heat or leak complaints. Unpaid city charges matter because the Department of Finance can sell liens for property tax, water and sewer charges and HPD emergency repair charges.

Rules that affect your use and resale

• Flip tax. New York's Business Corporation Law §501(c) allows co-ops to charge transfer fees provided for in their proprietary leases, occupancy agreements or offering plans. Find out the method and who pays (see co-op flip tax).
• Sublet policy. How long you must live there first, how long you may sublet, and any fee. See co-op sublet rules.
• Financing limits. Maximum financing and post-closing liquidity the board requires.
• Renovation rules. Alteration agreement, summer work rules, and approval times.
