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: $900,000
• Buyer's loan: $720,000 (20% down)
• MRT rate: 1.675% (loan over $500,000)
• MRT owed: $720,000 × 1.675% = $12,060

With a Purchase CEMA:

• Seller's existing mortgage balance: $450,000
• New money needed: $720,000 – $450,000 = $270,000
• MRT rate: 1.55% (new money under $500,000)
• MRT owed: $270,000 × 1.55% = $4,185

Gross savings: $7,875. After legal fees and the seller's 50/50 split of savings (standard practice), the buyer's net savings typically run $3,000 to $5,000. On larger loans, the savings are proportionally greater.

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 a CEMA also reduces the seller's transfer tax (the NYS transfer tax is not levied on the assigned mortgage amount), sellers receive their own benefit from cooperating. It is standard practice in New York for sellers to demand that any MRT tax savings be split 50/50 between buyer and seller as a condition of their participation.

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 legal fees: Your attorney will charge extra for the added complexity of drafting and reviewing the consolidation agreement. Expect $500 to $1,500 in additional attorney fees.
• Bank assignment fees: The seller's lender may charge a fee to assign the mortgage, often $250 to $750. Sometimes this can be negotiated.
• Closing delay: CEMAs require coordination between the seller's lender, the buyer's lender, and both attorneys. This typically adds two to four weeks to the closing timeline. In a market where sellers have competing offers, this delay 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 net buyer savings exceed $2,500 to $3,000, a CEMA is generally worth pursuing. Below that threshold, the administrative friction and closing delay may not justify the effort — especially in competitive markets where a four-week delay could lose you the property.

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 extra time into your closing schedule — CEMAs routinely add two to four weeks.

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.
