The Mortgage Recording Tax: The Biggest Closing Cost No One Warns You About
Ask a first-time condo buyer to name their biggest closing costs and they'll say the mansion tax. Often they're wrong. On a financed purchase under $1M there's no mansion tax at all — but the mortgage recording tax (MRT) still takes a four- or five-figure bite. It's the tax nobody budgets for.
What it is
New York taxes the recording of a mortgage against real property (NY Tax Law Article 11, plus city add-ons). No mortgage, no tax: all-cash buyers pay nothing. It's calculated on the loan amount, not the purchase price.
The rates in NYC (residential, 1–3 family and condos)
Loans under $500,000: total statutory rate 2.05%
Loans of $500,000 or more: total statutory rate 2.175%
By custom and statute, the lender pays 0.25% of that, leaving the borrower an effective 1.80% / 1.925%
There's also a small statutory deduction (currently $30 off for 1–2 family homes) — trivial but real
Example: $1.2M condo, 20% down → $960,000 loan → MRT ≈ $18,480. On a $2M condo with an $1.6M loan: $30,800.
The co-op exemption — and why it matters
Co-op purchases are financed with a loan secured by your shares and proprietary lease — personal property, not real property. No mortgage is recorded, so no mortgage recording tax applies. On a financed $1.5M purchase, this single difference saves a co-op buyer roughly $23,000 versus an equivalent condo. It's the largest structural closing cost advantage co-ops have.
CEMA: the legal way to shrink the MRT
A Consolidation, Extension and Modification Agreement (CEMA) lets a new loan piggyback on an existing recorded mortgage, so tax is paid only on new money (the gap between the old principal balance and your new loan).
Refinance CEMA: most common. Refinancing a $900,000 balance with a $950,000 new loan taxes only ~$50,000 of new money instead of $950,000.
Purchase CEMA: the seller's lender assigns their existing mortgage to your lender. If the seller's unpaid balance is $700,000 and your loan is $960,000, you pay MRT on ~$260,000 — saving nearly $13,500 in this example. Sellers often cooperate because a purchase CEMA can also reduce their transfer tax base by the assigned amount; buyers typically cover the seller's CEMA legal fees as an incentive.
The catches: both lenders must cooperate (not all do), it adds 30+ days and $2,000–$4,000 in fees, and it only pencils when the seller's remaining balance is substantial. Ask your attorney to run the math early — a CEMA can't be bolted on at the last minute.
Other things to know
New construction: MRT applies normally; there is no sponsor exemption for your loan.
Refinancing later: every newly recorded mortgage triggers the tax again unless you CEMA — a reason NYC owners refinance less casually than the rest of the country.
HELOCs: taxed on the credit line amount when recorded.
Commercial and 4+ family: higher rate (2.80% total in NYC).
Bottom line for buyers
When comparing a condo and a co-op at similar prices, add roughly 2% of your loan amount plus ~0.45% of the price (title insurance) to the condo side before deciding which is really cheaper. And if you're financing any condo purchase, ask two questions on day one: "What's the seller's current mortgage balance?" and "Will your lender cooperate with a purchase CEMA?"
