How much house can I afford?

How much house you can afford comes down to your income, debt-to-income ratio, credit score, and mortgage rate. A common guideline is the 28/36 rule: spend no more than 28% of your gross monthly income on housing, and keep total debt payments under 36%. On a $153,000 annual income (about $12,750 a month), that caps your mortgage payment at roughly $3,570. With a standard 30-year mortgage at a 6.49% rate, a payment like that supports a loan of about $565,401. Remember that property taxes, insurance, utilities, maintenance, and the size of your down payment all affect what you can comfortably afford.
