NYC Mortgage Calculator

NYC closing costs run 2-6% of the purchase price for buyers, with the spread driven by mansion tax (kicks in above $1M), mortgage recording tax (skipped entirely on co-ops), and title insurance (also skipped on co-ops). After 25+ years closing co-op and condo deals across Manhattan, Queens, the Bronx, and Brooklyn, I built this calculator to surface every NYC-specific charge in one screen: mansion tax, mortgage recording tax, title insurance, attorney, bank fees, and the property-tax variance between buildings.

How the NYC Mortgage Calculator Works

The calculator takes your purchase price, down payment, interest rate, loan term, and the carrying costs of the building (property tax, HOA or maintenance, homeowner insurance). It then layers in the NYC-specific closing costs that most national calculators leave out. The monthly payment combines principal and interest with property tax, HOA, and insurance, which is the total a lender treats as your housing obligation when they calculate your debt-to-income ratio.

Closing costs in NYC are larger and more itemized than the rest of the country. Your one-time costs at closing include the mansion tax (if applicable), mortgage recording tax (condos and houses only), title insurance (condos and houses only), your attorney, and your lender's fees. Cash to close is the down payment plus all of those closing costs combined.

Co-op vs Condo: Closing Cost Comparison

The table below shows a side-by-side for a $1.25M purchase with 20% down ($1M loan):

Flip taxes are set by each co-op board and range widely. Some buildings charge a flat fee of a few hundred dollars, others charge 2% to 3% of the sale price. The seller usually pays the flip tax, but a handful of boards require the buyer to pay. Always read the building's offering plan and current house rules.

NYC-Specific Quirks Most Calculators Miss

1. Mansion Tax Is a Cliff, Not a Slope

The mansion tax has been tiered since 2019. A $999,999 purchase pays zero. A $1,000,000 purchase pays $10,000. The 1.25% bracket starts at exactly $2M, so a $2,000,001 contract triggers an extra $5,000 over a $1,999,999 contract. Buyers regularly negotiate price concessions to land just below a bracket. Talk to your attorney before agreeing to a price that sits on a cliff.

2. Property Tax Bills Are Class-Based

NYC condos and co-ops are taxed as Class 2 property. The headline FY2026 rate is 12.502%, but it is multiplied against an assessed value, not market value. Assessment ratios run around 45%, with assessment caps that limit year-over-year increases. Two buildings on the same block can have very different effective tax rates depending on assessment history, J-51 abatements, 421-a abatements, or co-op/condo tax abatements. Pull the building's recent tax history from the NYC Department of Finance before you commit to the calculator's default 0.9% estimate. The NYC Property Tax Guide 2026 has the full breakdown.

3. Mortgage Recording Tax Skips Co-ops

The mortgage recording tax is the biggest NYC closing-cost trap for first-time buyers. At 1.925% on loans of $500k or more, the tax on a $1M loan is $19,250. The borrower pays, though the lender technically remits 0.25%. Co-op loans are share loans because they finance stock and a proprietary lease, not real estate, so the tax does not apply. This is one of the strongest financial arguments for buying a co-op over a similarly priced condo.

4. Title Insurance Is Real, and Negotiable on the Title Search

Condo and house buyers pay for a title insurance policy issued by a title company. Premiums are roughly 0.5% of the purchase price. The premium itself is set by the New York State Department of Financial Services, but the title-search fees, recording fees, and endorsement charges your title company quotes on top are negotiable. Always get two quotes.

5. Co-op Move-In Fees, Working Capital, and Reserve Contributions

Most co-op boards charge a move-in deposit ($500 to $1,500, typically refundable), a non-refundable move-in fee ($500 to $1,000), and many ask new shareholders to contribute two or three months of maintenance to building reserves at closing. These are not in the standard mortgage calculator anywhere on the web. Milton will pull your building's specific schedule from the offering plan or current house rules before you sign a contract.

Who This Calculator Is For

First-time NYC buyers underestimate cash-to-close by an average of 15% to 30% because national calculators silently skip mansion tax and recording tax. Investors comparing a condo to a co-op need the recording-tax line item to evaluate the financing math correctly. Sellers can use the calculator from the buyer's perspective to forecast what an offer at their list price would actually cost a financed buyer at closing, which is useful for setting a realistic asking price.

Once you have your numbers, the next step is a pre-approval letter from a lender and a buyer's representation agreement. The NYC Buyer Guide walks through the full process. If you are deciding between boroughs, Manhattan market data and the borough hubs for Brooklyn, Queens, and the Bronx show live RLS inventory and median pricing. To browse active inventory directly, compare NYC condos against NYC co-ops.

Frequently Asked Questions

Do co-ops pay the NYC mortgage recording tax?

No. Co-op shares are personal property, not real estate, so the 1.925% mortgage recording tax does not apply. Condo and house buyers pay it on the loan amount.

How is the NYC mansion tax calculated in 2026?

The tax starts at $1M in tiers: 1.00% from $1M, 1.25% above $2M, 1.50% above $3M, 2.25% above $5M, 3.25% above $10M, 3.50% above $15M, 3.75% above $20M, and 3.90% above $25M. The buyer pays.

What closing costs should a NYC buyer expect?

For a financed condo, total buyer closing costs typically run 4% to 6% of the price. Co-ops avoid recording tax and title insurance and typically run 1% to 3%.

How much should I put down on a NYC apartment?

Most co-op boards require 20% minimum, many top-tier buildings 25% to 50%. Condos generally accept 10% down with PMI. New developments commonly accept 10% down.

What is the NYC property tax rate?

The FY2026 Class 2 rate is 12.502%, applied to assessed value (roughly 45% of market value). Effective rates land between 0.6% and 1.2% of market value depending on building and abatements.
