Example calculations

Tap an example to prefill the calculator with sample values.

Two-income household

$165k income, $950 monthly debt, 20%+ down

A realistic household budget where the payment must stay within a standard backend DTI limit.

Result: Affordability rises with income, but taxes, insurance, and HOA still materially reduce the headline home price

Higher-debt buyer profile

$118k income with heavier recurring debt

A useful stress case for buyers who have strong income but less room after student loans, cars, or credit obligations.

Result: Debt service compresses the affordable home price much faster than many buyers expect

How the affordability model works

The calculator starts with gross monthly income, applies your target debt-to-income limit, and subtracts existing monthly debt payments to find the housing budget left over.

It then reverse-solves the home price that fits inside that budget after mortgage principal and interest, property tax, insurance, and HOA costs are all included.

Home affordability FAQs

How DTI limits, debt payments, taxes, and down payment change the realistic purchase budget.

Why can the affordable price be much lower than a lender preapproval?

Lenders may stretch to higher DTI limits, but taxes, insurance, HOA dues, and your own comfort threshold can all pull the practical budget lower than the maximum approved amount.

Does this include PMI?

No. If your down payment is below the level that avoids mortgage insurance, add an estimated PMI amount into the HOA field or subtract that amount from the monthly budget afterward.
