Mortgage
How Much House Can I Afford?
The better way to answer "How much house can I afford?" is to start with a monthly payment you can carry comfortably, then work backward into a loan amount and purchase price.
Listing prices are only the surface. Debt-to-income ratio, cash to close, taxes, insurance, mortgage insurance, HOA dues, repairs, and savings after closing all matter.

Start with payment, not price
A home price can look affordable until taxes, insurance, and mortgage insurance are added. A payment-first approach keeps the monthly budget in view.
Choose a target payment that leaves room for food, transportation, childcare, repairs, retirement savings, and emergencies.
The role of DTI
Debt-to-income ratio compares monthly debt payments with gross monthly income. Lenders use it to evaluate capacity, but the exact limit depends on loan program, credit profile, automated underwriting, and compensating factors.
Your personal comfort ceiling may be lower than the approval ceiling. That is normal and worth respecting.
| Item | Example |
|---|---|
| Gross monthly income | $8,500 |
| Other monthly debt | $850 |
| Max total debt at 36% DTI | $3,060 |
| Approx. available housing budget | $2,210 |
| Est. taxes + insurance + PMI + HOA | $560 |
| Est. principal + interest budget | $1,650 |
PITI and the hidden monthly costs
PITI means principal, interest, taxes, and insurance. Many buyers also need to account for mortgage insurance and HOA dues.
Repairs are not always in the lender payment, but they are real. A comfortable purchase should leave money for maintenance after closing.
How down payment changes affordability
A larger down payment can reduce the loan amount and may reduce or eliminate mortgage insurance. It can also lower the payment enough to change the price range.
Do not use every dollar for the down payment without checking cash to close. The Buyer Closing Cost Calculator can help estimate the other cash needed.
Why lender approval is not the same as comfort
A lender may approve a payment that technically fits underwriting guidelines. That does not mean the payment fits your life.
Think about income volatility, upcoming expenses, local insurance risk, commuting costs, and how much savings you want left after closing.
Final thoughts
Use a price range as a planning estimate, not a trophy. A home that leaves breathing room is often stronger than a home that uses every approved dollar. Start with the Mortgage Calculator and adjust until the full payment feels realistic.
FAQ
What DTI ratio do lenders want?
It varies by loan program and borrower profile. Lower DTI is generally stronger, but automated underwriting can allow higher ratios in some cases.
Should I include HOA fees?
Yes. HOA dues affect your monthly budget and may be considered in qualification.
Should I budget from gross income or take-home pay?
Lenders often use gross income, but your household budget should be tested against take-home pay.
Does a bigger down payment always help?
It can lower the payment, but keeping adequate reserves after closing can be just as important.
