Co-op Share Loans vs Mortgages in NYC

What you are actually buying, and what the loan is secured by

When you buy a New York City co-op you do not buy real estate. You buy shares in a corporation that owns the building, and those shares entitle you to a long-term proprietary lease for a specific apartment — that is how the New York Attorney General’s Real Estate Finance Bureau describes the structure. Shares of stock and a lease are personal property, not real property.

That single fact drives almost every practical difference between financing a co-op and financing a condo or a house. The loan is a share loan, not a mortgage. It is governed by Article 9 of the Uniform Commercial Code rather than by real property mortgage law. The lender perfects its security interest by filing a UCC financing statement — in NYC, recorded by the Office of the City Register through ACRIS, which the Department of Finance describes as showing “a security interest in personal property, including in a cooperative corporation.” No deed is recorded in your name, and no mortgage is recorded against the apartment.

The mortgage recording tax you do not pay

New York’s mortgage recording tax is, per NYS Department of Taxation and Finance memorandum TSB-M-96(2)R, “an excise tax on the privilege of recording a mortgage” on real property located in New York State. If nothing is recorded against real property, nothing triggers the tax. The NYC Department of Finance’s own statistical profile of the tax states plainly that mortgages on individual cooperative apartments do not incur mortgage recording tax liability.

For a NYC residential purchase that is real property — a house or a condo unit — the Department of Finance publishes the combined state and city rate as 2.05% of the loan amount below $500,000 and 2.175% at $500,000 or more. On one-to-three family homes and individual residential condo units the lender is responsible for 0.25 percentage points of that, which is why buyers usually see the figure quoted as 1.8% under $500,000 and 1.925% at $500,000 and above, per NYC Department of Finance rates in effect as of August 2026. Confirm the current rate and the exact allocation with your attorney and the ACRIS mortgage tax calculator before you budget it, since the split between borrower and lender is set by statute and can change.

The math, side by side

Two buyers, each putting 20% down on a $750,000 apartment, each borrowing $600,000:

At a $400,000 loan the same comparison is roughly $7,200 versus zero, using the 1.8% figure for loans under $500,000. This is real money at the closing table, and it is the single largest structural cost advantage co-ops hold over condos in New York City. It is not a reason on its own to choose a co-op — maintenance, board rules, sublet policy, and resale liquidity all cut the other way — but it belongs in any honest cost comparison.

No CEMA, because none is needed

On a real property refinance in New York, borrowers often use a Consolidation, Extension and Modification Agreement (CEMA) so the existing mortgage is assigned and modified rather than satisfied and re-recorded, which limits mortgage recording tax to the new money. A co-op share loan cannot use a CEMA, and does not need one: no mortgage recording tax applied at origination, so there is nothing to avoid paying twice. Ask a refinancing lender to quote the co-op closing costs directly rather than assuming a CEMA line item belongs there.

The recognition agreement and why the corporation has to cooperate

Because the collateral is shares plus a lease that the co-op corporation itself issued, the lender needs the corporation to acknowledge the lien. That acknowledgment is the recognition agreement, industry-standard on the Aztech form (frequently called the “Aztec form”). It is a tri-party agreement among the shareholder, the lender, and the co-op corporation, and it typically commits the corporation to notify the lender of a default under the proprietary lease, to recognize the lender’s interest in the shares and lease, and not to consent to a surrender or termination of the lease without the lender’s involvement. Fannie Mae’s Selling Guide requires state-specific co-op documentation including recognition agreements, and requires that UCC financing statements be filed as needed so the share loan sits in first-lien position.

Practical consequence: your closing depends on a third party — the co-op’s board or managing agent — signing a form on your lender’s paper. Many buildings maintain a list of lenders whose form language they already accept. If your lender is not on that list, or the form has non-standard provisions, the signature can take weeks. Ask your attorney early which recognition agreement form the building accepts.

Board approval is a second underwriting layer

A condo board can usually only waive or exercise a right of first refusal. A co-op board can decline you, and in New York it generally need not explain why, provided it stays within its bylaws, proprietary lease, and certificate of incorporation and exercises prudent business judgment — the standard the Attorney General’s guidance for co-op directors describes. Practically, that means you are underwritten twice: once by the lender, once by the building, and the building’s standards are often stricter.

Financing caps are set by the building

The maximum percentage you may finance is set by the co-op, not by your lender. In NYC it is common to see buildings cap financing at 75% or 50% of the purchase price, and some buildings permit no financing at all. Because these limits sit in building-level governing documents rather than in any public rate table, there is no citywide figure to quote — you have to get the number from the managing agent or the board’s purchase application before you make an offer. A pre-approval for 80% financing is worthless in a 50% building.

Liquidity and debt-to-income ratios boards impose

Boards commonly ask for post-closing liquidity — cash and marketable securities remaining after the down payment and closing costs, often expressed as a multiple of monthly maintenance plus loan payment — and for a debt-to-income ratio at or below a stated ceiling. Both are set by the building and are frequently tighter than what the lender requires. Fannie Mae’s Selling Guide points to its Eligibility Matrix for the lender-side credit score, reserve, and DTI requirements on co-op share loans; the board’s numbers are separate and additional.

The board package and the interview

The board package is a document-heavy application: tax returns, bank and brokerage statements, a financial statement, reference letters, the contract, and the loan commitment. After review, most buildings conduct an interview. Neither step is a formality, and a rejection after an accepted offer and a full loan approval is a real outcome. Build the timeline into your contract with your attorney.

Why fewer lenders make these loans

Share loans are non-standard collateral, require building-level review and a recognition agreement, and cannot be originated with the same automated workflow as a mortgage. A lender must be specially approved by Fannie Mae to deliver co-op share loans, documented through an addendum to its selling and servicing contract, and Fannie Mae publishes state-specific rather than multistate co-op documents because of variation in state law. The result is that many national lenders simply do not offer co-op share loans, while local banks, credit unions, and portfolio lenders that keep the loan on their own books dominate the NYC market. When you compare offers, confirm first that the lender actually originates co-op share loans in the borough you are buying in, and second whether the building has already worked with them.

Building-level items that can change your loan

The underlying mortgage. The corporation itself usually carries a blanket mortgage on the building. Its balance, rate, and maturity date affect the building’s finances and your maintenance, and Fannie Mae’s share loan LTV calculation differs depending on whether the borrower assumes a pro rata share of the blanket mortgage. Ask for the maturity date and whether a refinance is pending.

Flip taxes. Most NYC co-ops charge a transfer fee on resale, structured as a percentage of price, a per-share amount, or a share of profit. Fannie Mae’s eligibility rules place conditions on flip taxes, including a cap of 5% of property value for certain structures. A flip tax is a cost you will pay when you sell, so read the schedule in the offering plan and house rules.

HDFC co-ops are a separate category

HDFC co-ops are limited-equity buildings incorporated under Article XI of the New York State Private Housing Finance Law and supervised by HPD. Per HPD’s fact sheet for cooperative HDFC shareholders, they must house persons and families of low income — a statutory ceiling of 165% of Area Median Income, though individual buildings frequently impose stricter caps in their own certificate of incorporation, bylaws, deed, or regulatory agreement. Resale profit is limited, almost all sales carry a flip tax, and owner-occupancy is generally required with tight subletting limits. Financing an HDFC is harder because fewer lenders will lend against the regulatory restrictions. Our first-time buyer programs guide covers the income caps and buyer-side mechanics in more detail.

What to ask before you commit

• What percentage may be financed, per the board’s current policy?
• What post-closing liquidity and DTI does the board expect?
• Which recognition agreement form does the building accept, and which lenders are already on its list?
• What is the underlying mortgage balance, rate, and maturity date?
• What is the flip tax, and who pays it?
• What is the realistic board package and interview timeline?
