NYC Co-op Board REBNY Financial Statement Guide (2026): ≤28% Housing DTI, 24-Month Post-Closing Liquidity & Co-op vs. Condo Closing Costs

Before submitting an offer on a Manhattan or Brooklyn cooperative apartment, buyers must pass the Real Estate Board of New York (REBNY) Financial Statement stress test. Use our interactive 2026 REBNY DTI and Post-Closing Liquidity calculator to verify whether your liquid non-retirement assets and monthly carry meet strict 25%–28% co-op board underwriting standards.

What Is the REBNY Financial Statement & Why Do NYC Co-op Boards Require It?

Over 70% of the owner-occupied apartment inventory in Manhattan—and a substantial share of Brooklyn Heights, Park Slope, and Queens—consists of housing cooperatives (co-ops) rather than condominiums. When you purchase a co-op, you acquire shares in a private corporation and a proprietary lease, subject to the unfettered approval of the building’s Board of Directors. Every NYC buyer broker submits the standardized REBNY (Real Estate Board of New York) Financial Statement alongside the offer sheet to prove two non-negotiable financial ratios: Housing Debt-to-Income (DTI) and Post-Closing Liquidity.

The Two Golden Rules of NYC Co-op Board Underwriting: ≤ 28% DTI & 24 Months of Post-Closing Liquidity

Unlike mortgage banks that routinely approve borrowers up to a 43% back-end DTI and count 60%–70% of 401(k)/IRA balances as reserves, Manhattan and Brooklyn co-op boards enforce far stricter balance-sheet rules:

1. Housing Debt-to-Income Ratio (≤ 25% to 28%): Your combined monthly mortgage principal and interest (P&I) plus monthly co-op maintenance charges (and any other recurring debt) cannot exceed 25% to 28% of your predictable gross monthly base salary and multi-year averaged bonus.
2. Post-Closing Liquidity (12 to 36 Months — Typical 24 Months): After subtracting your cash down payment (20% to 50% minimum depending on the building) and buyer closing costs, you must retain at least 24 months of combined mortgage P&I plus maintenance in liquid, non-retirement assets (cash, money market, T-Bills, and unrestricted brokerage equities/bonds). Retirement accounts (401k, 403b, Traditional/Roth IRA) and illiquid private equity or real estate are excluded from primary post-closing liquidity.

Co-op vs. Condo Closing Costs in NYC (Why Co-ops Save 1.80%–1.925% in Mortgage Recording Tax)

While co-ops enforce tougher board admission standards, they offer a massive statutory closing cost advantage over NYC condominiums: because co-op shares are legally classified as personal property rather than real property, co-op buyers are 100% exempt from the New York City & State Mortgage Recording Tax (1.80% on loans under $500,000 and 1.925% on loans of $500,000 or more) and do not require a fee-simple title insurance policy ($4,000–$9,000 saved). On a $1,500,000 purchase with 25% down ($1,125,000 loan), buying a co-op instead of a condo saves $21,656 in NYC Mortgage Recording Tax alone.
