CEMA for commercial refinances in New York
A CEMA lets a New York commercial refinance avoid paying mortgage recording tax on the entire new loan. By assigning the old mortgage instead of satisfying it, tax under NY Tax Law §253 is due only on the new money above the surviving balance. Refinancing a $9 million balance into a $10 million loan can mean paying tax on roughly $1 million instead of $10 million — but the old lender has to cooperate, the assignment fee typically runs $1,500–$5,000, and it adds two to six weeks to closing.
The mechanics: assignment, gap mortgage, consolidation
A standard refinance satisfies the old mortgage of record and records a brand-new one for the full loan amount — and New York taxes the full amount recorded. A CEMA restructures that sequence into three linked documents so the old mortgage is never satisfied:
- Assignment. The existing lender assigns its mortgage — not the debt, the recorded lien — to the new lender for a fee, rather than accepting payoff and satisfying it.
- Gap mortgage. The new lender records a second, new mortgage for the difference between the old balance and the new loan amount — the only piece recording tax applies to.
- Consolidation, extension and modification agreement. The assigned mortgage and the gap mortgage are legally consolidated into a single lien with the new loan's rate, term, and amortization, so the borrower ends up with one note and one mortgage exactly as they would in a conventional refinance.
The glossary entry on CEMA covers the underlying defined term if you need the short version; this page focuses on how it plays out in a commercial deal specifically.
What it saves — and what it costs
The saving is the recording tax that would otherwise apply to the surviving balance. New York City's combined commercial rate on mortgages of $500,000 or more is 2.8% (see how mortgage recording tax is structured). Tax on new money only, instead of the full loan, is why CEMA deals concentrate in refinances where a meaningful balance survives — a small remaining balance on a large new loan captures most of the benefit; a fully paid-off or heavily amortized loan captures very little.
The cost side has three components. The old lender's assignment fee is typically $1,500 to $5,000, set at the lender's discretion and sometimes tied to loan size. Legal costs run higher than a standard refinance because counsel drafts a three-document consolidation package instead of a single mortgage, and title has to search and insure around the assignment chain. And timing: expect the process to add roughly two to six weeks versus a conventional refinance, driven almost entirely by how quickly the old lender processes the assignment.
When lenders decline to do a CEMA
A CEMA needs cooperation from a lender who is being paid off and has no ongoing economic interest in helping — which is why it cannot be assumed. Common reasons an old lender declines or drags:
- CMBS loans in special servicing or with a master servicer that has no standard process for assignment requests outside a full payoff.
- Smaller community banks without an operations team experienced in preparing assignment documents, or with an internal policy against them.
- Life insurance company loans, which are sometimes structured with prepayment or defeasance terms that make a straight payoff simpler for the lender to process than an assignment.
Confirm cooperation as an early diligence item — ideally before a borrower is quoted CEMA-adjusted numbers — since a refusal means reverting to a standard refinance and the full recording tax bill.
Purchase CEMA: the buy-side variant
On an acquisition, a purchase CEMA lets the buyer's new lender take assignment of the seller's existing mortgage instead of the seller satisfying it at closing, then consolidate it with new financing for the balance of the purchase price. It requires the seller to negotiate cooperation into the purchase contract and needs the seller's lender on board in addition to the buyer's — two institutions coordinating instead of one, which is why purchase CEMAs typically add more time than refinance CEMAs and are less common in competitive bidding situations where speed matters.
Worked example: $9M balance into a $10M loan
| Line item | Standard refinance | CEMA refinance |
|---|---|---|
| Recording tax base | $10,000,000 (full loan) | ~$1,000,000 (gap only) |
| NYC recording tax (2.8%) | $280,000 | ~$28,000 |
| Assignment fee + extra legal | $0 | ~$8,000–$12,000 |
| Net tax-related cost | $280,000 | ~$36,000–$40,000 |

Frequently asked questions
What does CEMA stand for and what does it actually do?
CEMA stands for Consolidation, Extension and Modification Agreement. Instead of satisfying the old mortgage and recording a brand-new one, the new lender takes an assignment of the existing mortgage and consolidates it with a new gap mortgage for the additional money. Because the original mortgage is never satisfied of record, New York's mortgage recording tax under NY Tax Law §253 is due only on the gap amount, not the full new loan.
How much does a CEMA typically save on a commercial refinance?
It scales with how much of the old balance survives the refinance. On a $10 million NYC commercial refinance replacing a $9 million balance, tax is owed on roughly $1 million of new money instead of $10 million — a saving in the range of $250,000 at the 2.8% combined commercial rate. The smaller the gap relative to the new loan, the bigger the percentage saved.
Does every lender accept a CEMA assignment?
No. The new lender needs the old lender to cooperate by assigning rather than satisfying the mortgage, and some institutions — particularly smaller banks, life companies, and CMBS special servicers — decline to do CEMA assignments as a matter of policy or loan-servicing constraint. Confirm cooperation before underwriting assumes the savings; it is not guaranteed.
Can a CEMA be used on a purchase, not just a refinance?
Yes, through a purchase CEMA: the buyer's lender takes assignment of the seller's existing mortgage instead of satisfying it, then consolidates it with new money for the balance of the purchase financing. It requires cooperation from the seller's lender in addition to the buyer's, which adds negotiation and typically extends the closing timeline by two to four weeks beyond a standard purchase.
How long does a CEMA add to closing compared to a standard refinance?
Typically two to six weeks, driven by the old lender's assignment processing time and the extra legal work of drafting a consolidation agreement rather than a single new mortgage. Borrowers on a tight timeline should confirm the current lender's assignment turnaround early — it is usually the pacing item, not the new lender's underwriting.
