## 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: 

- **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**.

- **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**.
