Lenders look at front ratio and back ratio

Do home affordability calculators work?

Dear Dr. Don,
Are these "how much house you can afford" calculators realistic? The homes in my area (Alexandria, Va.) range from $300,000 to millions. According to the calculators, I can't even get $100,000 homes. What am I to do?

I'm a single woman in my mid-20s with a salary of $59,000. I only have student loan ($13,000) and a car loan ($11,000), which amounts to an expense of $600/month for debt. I'm willing to buy and get a roommate. Is that my only option these days? Thank you.

Dear Yolanda,
These home affordability calculators are based on mortgage loan origination ratios known as the front ratio and the back ratio. The Bankrate glossary defines the front ratio as, "The percentage of monthly before-tax income that goes toward a house payment -- a key ratio that lenders use when deciding whether to approve a mortgage application. Traditionally, lenders didn't like it when the total mortgage payment (principal, interest, taxes and insurance) divided by gross monthly income exceeded 28 percent. Modern risk-based pricing, however, has made lenders more flexible."

The Bankrate glossary defines the back ratio as: "The sum of the house payment and all other monthly debt -- credit cards, car payments, student loans and the like -- divided by before-tax income. Traditionally, lenders were loath to extend borrowers' back-end ratios past 36 percent, but they often do now."

With a front ratio of 28 percent, you could afford monthly housing costs (PITI) of $1,377. Ignoring taxes and insurance; that means you could afford a $215,000 loan. Assume annual property taxes of $2,500 and annual insurance expense of $1,500 and you can afford a $160,000 home. That's pretty close to what Bankrate's home affordability calculator shows ($169,678) with your income and loan numbers, plus these hypothetical tax and insurance expenses, and assuming you have $40,000 for a down payment.

Getting a roommate can help with your cash flow but won't do anything on the front end to help you qualify for the mortgage. The typical mortgage for a primary residence won't consider the rental income from a roommate in qualifying you for the loan.

I don't have a ready answer for you as to how you can buy real estate in your market on your salary, but I can tell you that the home affordability calculators are pretty much on target when it comes to how much home you can afford.
