How it works

House affordability tools estimate a purchase-price range from income and debts—or from a fixed monthly housing budget—using common debt-to-income (DTI) guidelines.

Front-end DTI looks at housing costs versus income; back-end DTI includes other monthly debts. Classic teaching rules of thumb include combinations like 28/36, though lenders set their own caps by loan program.

Down payment size changes the loan amount and may trigger mortgage insurance (PMI) on conventional loans when equity is thin. Loan type (conventional, FHA, VA, or custom) adjusts which ratio set you explore.

Treat the output as a planning envelope, not a pre-approval. Credit, reserves, property type, and local taxes can move the real maximum up or down.

After you have a price range, estimate P&I with the Mortgage Calculator and check early-payoff strategies later with the Pay Off Calculator.

Frequently asked questions

Is this a pre-approval?
No. Lenders underwrite with credit, assets, and their own caps. Treat the result as a planning range before you talk to a loan officer.
What debts should I include?
Include recurring obligations that appear on a credit report style budget—car loans, student loans, minimum credit-card payments, and similar. Utilities and groceries are usually separate from DTI housing math.
Why does down payment change affordability?
A larger down payment reduces the loan size and can avoid PMI on some conventional loans, which changes the monthly housing cost that fits a DTI limit.
Should I buy at the maximum number?
Often no. Leaving room for maintenance, savings, and lifestyle usually matters more than stretching to the top of a ratio. Use the calculator as a ceiling, not a target.
