Quick Answer
A common guideline is that your monthly housing cost should stay around 28% to 30% of your gross monthly income, but true affordability also depends on debts, taxes, insurance, and your comfort level.

Start With Your Income
The first step is understanding how much you earn each month. Lenders often look at your income before taxes, but your personal comfort level should also take into account what you actually take home.
Use a Monthly Housing Rule
Many people start with the 28% rule. That means keeping housing costs at or below roughly 28% of gross monthly income.
That can include:
- Mortgage principal and interest
- Property taxes
- Homeowners insurance
- Mortgage insurance, if applicable
Look at Existing Debt
Affordability is not just about income. If you already have car payments, student loans, or credit card balances, those obligations reduce how much house fits comfortably into your budget.
Do Not Ignore the Down Payment
Your down payment affects more than just the amount you borrow. A larger down payment can reduce your monthly payment and lower the total interest you pay over time.
Remember the Costs Beyond the Mortgage
Homeownership includes more than the mortgage payment. Maintenance, repairs, utilities, HOA dues, and furnishing costs can all stretch a budget if you only focus on the loan itself.
Comfort Matters More Than Approval
Just because a lender approves a certain amount does not mean that amount feels comfortable for your lifestyle. Many buyers prefer to stay below the maximum to leave room for savings, flexibility, and unexpected expenses.
Test Multiple Price Ranges
Instead of asking for one perfect answer, compare several home prices, rates, and down payment amounts. That gives a better feel for what is realistic in your situation.
Final Thoughts
The right home budget is the one that lets you keep up with housing costs without squeezing every other part of your life.
Use your numbers, compare a few scenarios, and aim for a payment that still leaves room to save.
