What Are 2026 Long Island & NYC Refinance Rates and When Does a NY Tax Law § 255 CEMA Refinance Pay Off?
TL;DR (2026 Verified Answer): In 2026, Long Island (Nassau and Suffolk), New York City, and Westchester 30-year refinance rates average 5.875%–6.25% APR (high-balance conforming limit $1,209,750). Unlike most states, New York imposes a steep Mortgage Recording Tax (MRT) of 1.05%–1.30% in Nassau/Suffolk/Westchester and 1.80%–1.925% in NYC on new mortgages. By executing a Consolidation, Extension, and Modification Agreement (CEMA under N.Y. Tax Law § 255), you assign your existing mortgage note to the new lender and pay $0 MRT on the unpaid principal balance—saving $7,875 to $15,400 on an $800,000 refinance.

| NY Downstate County (2026) | 2026 High-Balance Conforming Cap | Borrower MRT Rate (Standard Refi) | MRT Owed Without CEMA ($800k Loan) | Net Savings With NY § 255 CEMA |
|---|---|---|---|---|
| Nassau & Suffolk (Long Island) | $1,209,750 (1-Unit) | 0.80% – 1.05% Borrower Share | $6,400 – $8,400 | Saves $4,800 – $6,600 Net |
| NYC (Manhattan, Brooklyn, Queens, Bronx, SI) | $1,209,750 (1-Unit) | 1.80% (<$500k) | 1.925% (≥$500k) | $15,400 | Saves $13,200 – $13,900 Net |

Do you pay New York Mortgage Recording Tax when refinancing a house in Long Island or NYC in 2026?
In a standard rate-and-term or cash-out refinance where the old mortgage is satisfied and a new mortgage is recorded, New York charges full Mortgage Recording Tax (0.80%–1.05% borrower share in Nassau/Suffolk/Westchester; 1.80%–1.925% in NYC). However, if you use a NY Tax Law § 255 CEMA (Consolidation, Extension, and Modification Agreement), the existing unpaid principal is assigned to the new lender and you pay Mortgage Recording Tax only on any new cash-out money added (or $0 MRT on a rate-and-term refinance). Co-op apartments are always 100% exempt from MRT.
TL;DR — 2026 Long Island & NYC Refinance Benchmark (Verified against NY Tax Law § 253 & § 255): In 2026, 30-year fixed mortgage refinance rates across Long Island (Nassau and Suffolk Counties), New York City, and Westchester average 5.875%–6.25% APR for high-balance conforming loans (up to the $1,209,750 FHFA high-cost ceiling) and 6.125%–6.50% APR for Jumbo loans. Because New York State levies a hefty Mortgage Recording Tax (MRT) of 1.05% in Nassau/Suffolk/Westchester and 1.80%–1.925% in NYC on newly recorded mortgages, refinancing without a Consolidation, Extension, and Modification Agreement (CEMA under N.Y. Tax Law § 255) adds $8,400 to $19,250 in upfront tax drag. Structuring your refinance as a NY § 255 CEMA eliminates 100% of the MRT on your existing unpaid principal balance, cutting your rate-drop breakeven horizon from 42 months to 14–18 months.

How Does a NY Tax Law § 255 CEMA Refinance Eliminate Mortgage Recording Tax in Long Island & NYC?
In 43 states, refinancing a mortgage incurs only minor county clerk recording fees ($100–$250). In New York State, however, N.Y. Tax Law § 253 imposes a statutory Mortgage Recording Tax (MRT) on every newly recorded mortgage security instrument (excluding co-op apartment loans, which are secured by UCC-1 shares rather than real property deeds). If your new lender simply pays off and satisfies your old mortgage note and records a brand-new $800,000 mortgage, you must pay the full county MRT all over again. Under N.Y. Tax Law § 255, executing a Consolidation, Extension, and Modification Agreement (CEMA) assigns your existing unpaid principal balance from Lender A to Lender B so that MRT is owed ONLY on the “new money” gap ($0 MRT on a rate-and-term refinance):
| Downstate NY County (2026) | Total Statutory MRT Rate (Lender Pays 0.25%) | Borrower MRT on $800k Refi (Without CEMA) | Typical CEMA Assignment & Legal Fees | Net Cash Saved by Using NY § 255 CEMA |
|---|---|---|---|---|
| Nassau County (Long Island) | 1.05% Total (0.80% Borrower Share − $30) | $6,370 | ~$1,500 – $1,850 | Saves $4,520 – $4,870 Net |
| Suffolk County (Towns of Huntington, Babylon, Islip, Brookhaven, Smithtown) | 1.05% Total (0.80% Borrower Share − $30) | $6,370 | ~$1,500 – $1,850 | Saves $4,520 – $4,870 Net |
| Suffolk East End (5 Peconic Towns) & Westchester County | 1.30% Total (1.05% Borrower Share − $30) | $8,370 | ~$1,600 – $1,950 | Saves $6,420 – $6,770 Net |
| New York City (1–3 Family & Condos ≥ $500k) | 2.175% Total (1.925% Borrower Share) | $15,400 | ~$1,750 – $2,200 | Saves $13,200 – $13,650 Net |
To compare whether a full CEMA refinance, a $250 lump-sum mortgage recast (Mortgage Recast vs. Refinance Calculator), or an interest-only HELOC second lien (HELOC Payment Calculator) delivers the highest internal rate of return, test your loan numbers in our Mortgage Refinance Breakeven Calculator.
