How Much NYC Apartment Can You Afford?

On a $1,000,000 NYC co-op with 20% down at 6.5%, you would generally need to earn about $263,000 a year to clear a typical board's 28% housing ratio, roughly $50,000 more income than a condo at the same price would require. After 25+ years closing co-op and condo deals across Manhattan, Queens, the Bronx, and Brooklyn, I built this calculator to show that gap up front, because the price you can afford depends as much on whether you are buying a co-op or a condo as it does on your income.

How the NYC Affordability Calculator Works

The calculator takes your annual household income, your monthly non-housing debts (auto, student loans, credit-card minimums), the cash you have for a down payment, and a mortgage rate. It then estimates the highest purchase price you could reasonably support, separately for a co-op and a condo, because the two qualify on different math.

It works backward from two limits and reports the lower one. The first limit is income: how much monthly housing cost your income supports. The second limit is cash: with a 20% down-payment assumption, your cash divided by 0.20 is the most expensive home that down payment can reach. If income is the tighter constraint, the result is labeled income-limited. If your cash is the tighter constraint, it is labeled down-payment-limited. Knowing which one binds tells you whether to focus on raising income, paying down debt, or saving more cash.

Post-Closing Reserves: The Cash Most Buyers Forget

The down payment is not the finish line. Most co-op boards want to see liquid reserves left over after you close, commonly 12 to 24 months of mortgage plus maintenance, sitting in accounts they can verify. The calculator estimates 24 months for co-ops and about 6 months for condos. On a co-op with a $4,700 true monthly cost, that is more than $110,000 in reserves a board may expect to see on top of your down payment and closing costs. Buyers who budget only for the down payment are the ones who stall at the board package stage.

What the True Monthly Cost Includes

The true monthly figure is principal and interest plus the building carry, which is maintenance or common charges combined with property taxes. The calculator estimates the carry at about 1.3% of price a year for co-ops (maintenance usually folds taxes in) and about 1.1% a year for condos (common charges plus a separate tax bill). Your building's actual figure can be higher or lower depending on its finances, tax abatements, and underlying mortgage, so treat the carry as an estimate and confirm the real numbers from the offering plan or the most recent financial statement.

From an Estimate to an Offer

This tool gives you a planning range, not a pre-approval. The next step is a pre-approval letter from a lender, which reflects your credit score, documented income, and the specific loan program. Once you have that, you can compare your range against live inventory. The NYC Mortgage Calculator breaks down the monthly payment and total cash to close at a specific price, and the Closing Cost Calculator itemizes mansion tax, recording tax, and the rest. For the full process from search to closing, the NYC Buyer Guide walks through each step.

To see what your estimated range actually buys, compare active NYC co-ops against NYC condos, or browse by borough across Manhattan, Brooklyn, Queens, and the Bronx, each with live RLS inventory and median pricing.

Frequently Asked Questions

How much do I need to earn to buy a $1,000,000 co-op in NYC?

As an estimate, with 20% down at 6.5%, principal and interest run about $5,057 a month and maintenance plus taxes add roughly $1,083, for about $6,140 total. At a 28% housing ratio that points to about $263,000 a year. This is an estimate, not a pre-approval; boards and lenders set their own thresholds.

How much down payment do I need for a NYC co-op?

Most co-op boards require at least 20% down, and many higher-end buildings require 25% to 50%. Condos generally allow 10% down with mortgage insurance. This calculator uses 20% down for both as a conservative default.

What are NYC co-op post-closing liquidity requirements?

After the down payment and closing costs, most co-op boards want cash reserves left over, commonly 12 to 24 months of mortgage plus maintenance held in liquid accounts. The calculator estimates 24 months for co-ops and about 6 months for condos. The exact figure is set by each board and lender.

Is a co-op or a condo more affordable in NYC?

It depends on the constraint. Co-ops usually cost less per square foot and skip the recording tax and title insurance, lowering closing costs. Condos are easier to qualify for financially but carry higher closing costs and often higher prices. The calculator shows both columns so you can compare your own numbers.

Why does the co-op estimate come out lower than the condo estimate?

Co-op boards apply a stricter front-end housing ratio, around 28%, and count maintenance inside it. Condo lenders use a back-end ratio closer to 43% that subtracts other debts but allows more room overall. With the same income, the co-op math is tighter. These are estimates and individual buildings vary.
