CEMA Mortgage New York: How the Purchase CEMA Saves Thousands on Recording Tax

The Mortgage Recording Tax in New York City runs between 1.55% and 1.675% of your loan amount — one of the most significant closing costs a condo or single-family home buyer faces. A Purchase CEMA is the legal tool that experienced buyers and attorneys use to reduce that liability substantially, sometimes by $8,000 to $15,000 or more on a single transaction.

Most first-time buyers have never heard of it. Here's how it works and when it's worth doing.

What Is a CEMA?

CEMA stands for Consolidation, Extension, and Modification Agreement. A Purchase CEMA (sometimes called a "Purchase Money CEMA" to distinguish it from refinancing CEMAs) is a legal arrangement where the seller's existing mortgage is assigned to the buyer's new lender rather than being paid off at closing.

The buyer's lender then consolidates the assigned mortgage with whatever additional "new money" the buyer needs. The two amounts are combined into a single mortgage of record under the buyer's name.

The critical benefit: the Mortgage Recording Tax is only charged on the new money — the difference between the seller's outstanding principal and the buyer's total loan amount. The seller's existing mortgage, because it was already taxed when the seller originally recorded it, is not taxed again.

A Concrete Example

Without a CEMA:

• Purchase price: $1,000,000
• Buyer's loan: $800,000
• Gross MRT rate: 1.925% (loan of $500,000 or more)
• MRT owed: $800,000 × 1.925% = $15,400

With a Purchase CEMA:

• Seller's existing mortgage balance: $500,000
• New money needed: $800,000 – $500,000 = $300,000
• Gross MRT rate: 1.925%
• MRT owed: $300,000 × 1.925% = $5,775

Gross savings: $9,625. After the seller's commonly negotiated 50% share and about $1,000–$2,000 in additional attorney and bank-coordination fees, the buyer's net savings in this example are roughly $2,800–$3,800.

When Does a CEMA Apply?

A Purchase CEMA only works when:

1. The property is real property — a condo, townhouse, or single-family home. Co-ops are not eligible because co-op financing uses share loans, not recorded mortgages.

2. The seller has an existing mortgage with a balance. CEMAs don't work on all-cash sales or when sellers own free and clear.

3. The seller's current lender agrees to participate. This is not guaranteed. Some lenders charge assignment fees or are administratively slow to cooperate. If the seller has a small-balance loan nearing payoff, the complexity may exceed the benefit.

4. The buyer's new lender agrees to accept the assignment. Most major lenders who regularly operate in New York do this routinely. Out-of-state lenders or online mortgage companies may not be set up for it.

The 50/50 Savings Split

Because seller cooperation is required and the buyer receives the MRT savings, sellers commonly negotiate a 50/50 share of those savings as a condition of their participation. It is standard practice in New York for the MRT tax savings to be split between buyer and seller.

This split needs to be negotiated and documented. If you're considering a CEMA, discuss it with your attorney during contract negotiations — not at the closing table.

What a CEMA Costs

Additional costs specific to a CEMA include:

• CEMA coordination and legal fees: Additional attorney and bank-coordination fees typically total $1,000–$2,000.
• Closing coordination: CEMAs require coordination between the seller's lender, the buyer's lender, and both attorneys, which can delay closing. In a market where sellers have competing offers, the extra coordination can cost you the deal.

Running the Numbers: Is a CEMA Worth It?

The math is case-specific. A basic framework:

1. Calculate the gross MRT you'd pay without a CEMA (loan amount × applicable rate)
2. Calculate the MRT on just the new money portion (gap × applicable rate)
3. The gross savings = step 1 minus step 2
4. The net buyer savings = (gross savings ÷ 2) minus additional legal fees minus any bank fees

If the expected buyer share of the savings exceeds the additional fees and the parties can accommodate the coordination, a CEMA may be worth pursuing. Discuss the timing and net savings with your attorney and lender before committing.

A CEMA is most valuable when:

• The seller's existing mortgage balance is large (leaves a smaller "new money" gap)
• Your loan amount is large (higher absolute MRT savings)
• The closing timeline is flexible
• Both buyer's and seller's lenders are CEMA-experienced

CEMAs and Refinances

There's a separate type of CEMA used in refinancing — a Refinancing CEMA — where a homeowner refinancing their existing mortgage uses the CEMA structure to reduce MRT on the new loan. This has different mechanics than a Purchase CEMA but follows the same principle: only the new money portion is taxed.

If you're a current homeowner refinancing, ask your lender and attorney about the Refinancing CEMA. The savings calculation is similar, though it involves only one lender (your current lender and new lender, which may be the same institution).

The CEMA in Practice: What Buyers Should Do

1. Ask your attorney about CEMA eligibility early in the transaction — before the contract is signed, while there's still room to negotiate seller cooperation.
2. Confirm your lender handles CEMAs. Not all lenders do. If your lender has never done a CEMA, find one that has, or budget for the full MRT.
3. Get the CEMA terms documented in the contract rider, including the fee split and the timeline.
4. Build flexibility into your closing schedule — CEMA coordination can delay closing, so confirm the expected timing with both lenders and both attorneys.

The Purchase CEMA is one of the most effective tax-saving tools available to New York real estate buyers — and one of the least understood by first-time buyers. The New York First-Time Home Buyer Guide includes a CEMA decision framework, the questions to ask your lender, and a step-by-step timeline for executing the process without delaying your closing unnecessarily.
