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**.

Downstate New York homeowners who purchased or financed between late 2022 and 2024 at **7.00%–7.75% APR** are the single largest refinance cohort in the Northeast corridor in 2026. Thanks to the Federal Housing Finance Agency (FHFA) high-cost county designation across all five NYC boroughs, **Nassau County, Suffolk County, Westchester County, and Rockland County**, the 2026 **1-unit High-Balance Conforming Loan Limit is $1,209,750** (and **$1,548,975 for 2-unit properties; $1,872,225 for 3-unit; $2,326,875 for 4-unit**), allowing Long Island and NYC homeowners to refinance balances up to $1.21M without paying non-agency jumbo rate spreads: Downstate NY Loan Tier & Product (2026) | Loan Amount Cap (1-Unit) | 2026 Benchmark Refi Rate (APR) | Monthly P&I on $800k (Old 7.25% vs. 2026 Rate) | Annual Cash Flow Saved | 30-Year Fixed Baseline Conforming | Up to $806,500 | 5.75% – 6.125% | $5,457 → $4,732 / mo (-$725/mo) | +$8,700 / year | 30-Year Fixed NY High-Balance (LI / NYC / West.) | $806,501 – $1,209,750 | 5.875% – 6.250% | $5,457 → $4,796 / mo (-$661/mo) | +$7,932 / year | 15-Year Fixed High-Balance Refinance | Up to $1,209,750 | 5.125% – 5.500% | Rapid Principal Paydown (-$392k Interest) | Saves $392,000+ Lifetime Interest | 30-Year Fixed / 7-1 ARM Portfolio Jumbo | $1,209,751 – $5,000,000+ | 6.000% – 6.450% (Relationship Pricing) | -$1,180/mo on $1.5M Jumbo Loan | +$14,160 / year | ## 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](https://eastcorpcapital.com/calculators/mortgage-recast-vs-refinance/)), or an **interest-only HELOC second lien** ([HELOC Payment Calculator](https://eastcorpcapital.com/calculators/heloc-payment/)) delivers the highest internal rate of return, test your loan numbers in our [Mortgage Refinance Breakeven Calculator](https://eastcorpcapital.com/calculators/mortgage-refinance-breakeven/).
