What home price fits my monthly payment?

A lender can tell you the most you might borrow. This starts with what you actually want to pay each month, then works backward to a price range — taxes, insurance and mortgage insurance included.

Estimate for education only — not a rate quote, pre-approval, or commitment to lend. Works backward from the payment you enter using a 30-year term, 1.35% estimated property tax, 0.35% homeowners insurance, and mortgage insurance where the down payment is under 20%. Cash needed adds roughly 3% for closing costs; your actual costs depend on the property, contract, title company and taxes. The optional guideline comparison uses a 43% debt-to-income ratio, which is a general underwriting reference and not an approval. Better Rate Mortgage · NMLS #2401335 · Equal Housing Lender.

Budget and affordability questions, answered

How much house can I afford on a $2,500 monthly payment?

It depends on your down payment, rate, loan type, and how much of that payment goes to taxes, insurance and mortgage insurance rather than the loan itself. Enter your number above and the calculator works backward to a price range. In St. Louis, taxes and insurance typically consume a meaningful share of the payment, so the price a given payment supports here differs from national rules of thumb.

What is the difference between what I qualify for and what I should spend?

Qualifying is a lender calculation based on your income, debts and credit — commonly using a debt-to-income ratio around 43%. What you should spend is a personal decision about the rest of your life: savings, travel, childcare, retirement. They are frequently different numbers, and the qualifying number is usually the larger one. This calculator starts from what you want to pay, then optionally shows the guideline estimate alongside it so you can see the gap.

Does this include taxes and insurance?

Yes. The price range assumes your payment covers principal, interest, estimated property taxes, homeowners insurance, mortgage insurance where applicable, and any HOA dues you enter. That is why the price it returns is lower than calculators that only account for principal and interest.

Why is my price range limited by my down payment?

Each loan program has a minimum down payment — commonly 3% conventional, 3.5% FHA, and 0% for VA. If your savings would not cover that minimum on the price your payment supports, the down payment becomes the constraint rather than the payment. The calculator tells you when that happens.

How much cash do I need beyond the down payment?

Closing costs commonly run around 3% of the purchase price, though the actual figure depends on the contract, title company, lender fees and prepaid taxes and insurance. The cash estimate here adds roughly 3% to your down payment as a planning figure. It is deliberately rough — a real estimate needs the specific property.
