See what home price your monthly payment supports.

Set a target monthly principal and interest payment, a rate and a down payment to see the purchase price it supports. If you are selling a home to buy the next one, enter the sale price and payoff to check the down payment is funded. Leave the sale price at $0 if you are a first-time buyer. Everything recomputes as you type.

Selling a current home (optional)

Sale price$0

Leave at $0 if you are not selling a home. Use a realistic estimate or a recent comparable sale, not a list-price hope.

Selling costs7.0%

Agent commission plus seller closing costs, as a share of the sale price.

Existing mortgage payoff

Remaining balance on the loan being paid off at sale.

Other funds

Cash on hand

Checking and savings you are willing to put toward the purchase.

Gifts or other funds

New mortgage

Down payment$50,000

Target monthly P&I payment$2,500/mo

Principal and interest only. Property tax, insurance and PMI are added separately in the result.

Interest rate6.50%

Loan term

Property tax rate1.00%/yr

Annual, as a percent of purchase price. Varies widely by state and county. Homeowners insurance is assumed flat at $120/mo.

Your payment, rate, term and down payment support a purchase price of about $0.

Sale price, selling costs, cash and other funds do not change the price. They only decide whether the down payment is actually funded: see the check below the table.

Summary

Method

The loan a payment supports is the standard amortization formula solved for principal: loan = P × ((1 + r)^n - 1) / (r × (1 + r)^n), where P is the monthly principal and interest payment, r is the annual rate divided by 12 and n is the term in months. Purchase price is that loan plus the down payment.

PMI is estimated at 0.75% a year of the loan when the down payment is under 20% of the price. Actual rates vary by lender and credit.
Property tax is the rate you set times the purchase price, divided by 12.
Insurance is a flat $120 a month.
Net proceeds are the sale price minus selling costs minus the mortgage payoff. Available funds add cash on hand and gifts or other funds.

Not financial or lending advice. Real qualification depends on gross income, credit and the full debt-to-income underwriting a lender will compute directly. A sale price estimate is not an appraisal.
