Debt-to-income ratio: It’s about what you make—and what you owe
For a quick back-of-the-napkin calculation, try tripling what you (and your partner, if you’re buying together) make in a year. For example, if your income totals $100,000 a year, this means you can afford a home worth $300,000.
“The general rule of thumb is that you can purchase a home that costs about three times your annual salary,” says Harrine Freeman, a financial expert and the owner of H.E. Freeman Enterprises.
The way to factor in your income and debts is called your debt-to-income ratio, or DTI. To find this magic number, you divide your debt by your income. If, for example, your monthly income is $6,000 and your debt $500, then your DTI is 8.3% ($500/$6,000 = 8.3%).
And that’s OK: Ideally, your DTI should be 36% or less. Some lenders will allow a DTI of up to 43%, but lower is better, because it means you’re less strapped for cash.
How a home affordability calculator can help
Not good with numbers? A home affordability calculator can do these calculations for you. Just punch in your income, debt, even your dream neighborhood, and it will tell you what price of home you can afford.
Keep in mind that this is just a ballpark start: To get a more fine-tuned assessment, contact a lender, who will sit down with you for free, take a look at your finances, and help you figure out how large a home loan you can handle.
“Working with a great mortgage lender will help you determine what you can actually afford, compared to what you think you can afford,” says Phillip Salem, a real estate agent with Triplemint in New York.
