How this Naperville mortgage affordability calculator works

Lenders look at your debt-to-income ratio. Housing costs (principal and interest, property tax, homeowners insurance and mortgage insurance) should stay under about 31% of your gross monthly income, and housing plus your other monthly debts under 43%. The calculator finds the highest home price that passes both tests with your down payment, on a 30-year fixed loan.

Illinois rules and numbers this calculator uses

Debt-to-income
31% for housing and 43% total, the FHA standard and the long-time Qualified Mortgage limit. Some conventional loans go higher with strong credit and savings.
Down payment
At least 3% on a conventional first-time buyer loan (3.5% on FHA). Under 20% down, private mortgage insurance of about 0.6% of the loan a year is added to the payment.
Property tax
About 1.79% of the home's value a year, the Illinois average for owner-occupied homes (2024 Census ACS).
Insurance
Homeowners insurance assumed at $150 a month; it varies a lot by home and location.
Rate
Starts at 7.40% (Freddie Mac 30-year average, October 2026). Change it to the rate you have been quoted.

An estimate, not a mortgage approval or pre-approval. Your credit, income type, the property and the lender all change the answer; a mortgage broker confirms your real number.

How does the Naperville mortgage affordability calculator work?
It estimates the highest home price you can qualify for using your income, debts, down payment, and interest rate. It includes PMI and property tax calculations.

Conventional loans require at least 3% down for first-time buyers, while FHA loans need 3.5%. VA and USDA loans may allow 0% down for eligible buyers.
How do interest rates affect how much house I can afford?
Higher interest rates increase monthly payments, reducing the home price you can afford. The calculator uses a starting rate of 7.40%, which changes weekly.
How do my debts impact the mortgage amount I can qualify for?
Higher monthly debts reduce the mortgage amount you can qualify for, as lenders consider total debt payments relative to income.

The property tax rate is about 1.79% of the home's value per year, based on the 2024 Illinois average for owner-occupied homes.
What is the difference between mortgage pre-approval and pre-qualification?

Private mortgage insurance (PMI) is required on conventional loans with less than 20% down, costing about 0.6% of the loan annually.
