The Most Affordable Places to Buy a Home in America

Determining the affordability of living in a certain place involves a lot of variables, but the make-or-break expense tends to be how much it actually costs to have an address there — that is, what rent or mortgage payments are.

One of the ways to calculate home affordability is to look at the average income in that area and see how the average mortgage payment in the same area compares. (Try our Home Affordability Calculator to see how your credit can impact how much house you can afford.)

Nationwide, the mortgage payment on an average-priced home in the U.S. (assuming a 3% down payment and including homeowners insurance, private mortgage insurance and property taxes) takes up 36.5% of the average wage in the first quarter of 2015, according to a quarterly analysis from housing data company RealtyTrac.

That’s an improvement from 37.4% at the same time last year, but a mortgage payment requires more of monthly wages than it did in the first quarter of 2013, when it took up 33.5% of homeowners’ income.

In some places, the average monthly mortgage payment takes up much more of consumers’ paycheck. For example, the average mortgage payment for a home in Eagle County, Colo., was 138.5% of the average income there in the first quarter. That made it the least affordable place to buy a home early this year (Eagle County includes resort town Vail and the White River National Forest), followed by Kings County, N.Y., (aka Brooklyn, where you need 126.3% of the average income to afford the monthly mortgage payment on an average-priced home) and Marin County, Calif., (San Francisco metro area, 119.3%).

In most of the country (68% of counties), home price appreciation has increased at a faster rate than wage growth between the first quarter of 2014 and the first quarter of 2015, but mortgage rates have fallen in that same period of time, improving home affordability in most of the country.

Should interest rates rise (and wage growth and home price appreciation remain constant), home affordability will drop. This is a big issue facing aspiring homeowners, as many experts anticipate interest rates rising in the next several months. Your credit score has a huge impact on what interest rate you’ll get on a mortgage, which is why it’s important to check your credit before you buy a house (or start looking).
