The online calculators lie, because they ignore almost everything that decides your number here. Here is how a lender and an experienced agent actually figure out what you can afford.
A lender approves you based on the biggest monthly payment you can carry, then we work backward to a price. That payment depends on your income, your existing debts, your down payment, and your credit, plus interest rates.
Lenders look at your debt to income ratio, roughly aiming for total debts around 43 to 45% of your gross income. Every dollar of monthly debt, the car payment, the student loans, the cards, directly cuts the mortgage payment they will give you. Paying down debt before you apply is often the fastest way to afford more house, sometimes worth tens of thousands in buying power.
Your real payment is not just the loan. It is PITI, principal, interest, taxes, and insurance, and in NYC taxes vary a lot. If you buy a condo you add common charges, and a co op adds monthly maintenance that can run several hundred to over a thousand dollars, and the lender counts all of it. Think in full monthly cost, not sticker price.
Affording the payment is only half of it. You also need cash for the attorney, title, the mortgage recording tax, the mansion tax if you hit 1,000,000, and if you buy a co op, the reserves the board requires you to keep after closing. A buyer who can make the payment but cannot cover the closing costs and reserves is not actually ready.
A lender will often approve you for the absolute maximum their guidelines allow, and that number can feel great in a spreadsheet and terrible in real life. Find your maximum, then shop below it, at the payment you can afford on a normal month, not a perfect one. Buying at the ceiling with no cushion is how a home turns into a trap.
