Short Answer
A general rule is your monthly housing payment should not exceed 28% to 30% of your gross monthly income. This includes mortgage principal and interest, property taxes, homeowners insurance, and any HOA fees. Lenders look at this number along with your total debt-to-income ratio, which ideally stays under 43%.
Understanding what you can really afford
Knowing how much home you can afford starts with the numbers, but it is about more than just what a lender approves. Your comfort zone is just as important as your maximum approval amount.
The 28%/36% rule
Lenders use two key ratios to determine how much they will lend you. The front-end ratio says your total housing costs (mortgage, taxes, insurance, HOA) should not exceed 28% of your gross monthly income. The back-end ratio says all monthly debt payments (housing plus car loans, student loans, credit cards, etc.) should stay under 36% of your income. Some loan programs allow higher ratios, but staying within these guidelines keeps you in a comfortable position.
What lenders look at
When you apply for a mortgage, lenders evaluate your income, credit score, debt-to-income ratio, employment history, and assets. In Northwest Indiana, property taxes vary significantly by community, which affects your monthly payment. A home in Munster or Crown Point may have different tax rates than one in Hammond or Highland. This is factored into your qualifying numbers.
How to calculate your budget
Start with your gross monthly income. Multiply by 0.28 to get your maximum monthly housing payment. Subtract estimated property taxes, insurance, and HOA fees (a lender can help with these numbers). What remains is your monthly principal and interest payment. Use that to estimate the home price you can afford based on current interest rates. I work with local lenders who can run these numbers for you with no obligation.
The Northwest Indiana advantage
Because home prices in Northwest Indiana are significantly lower than in the Chicago suburbs, your buying power goes much further. With a monthly housing budget of $2,000, for example, you can afford a significantly larger home in Crown Point, Schererville, or St. John than you could in comparable Illinois suburbs. This is one of the main reasons families relocate across the state line.

Liz's Advice
The most important thing I tell my buyers is to find a home within your comfort zone, not just your maximum approval amount. Just because a lender says you qualify for $400,000 does not mean you will feel good about that payment every month. I walk my clients through the full picture: taxes, insurance, utilities, maintenance, and how each fits into your lifestyle.
