Zillow highlights 36 metros where high school grads can afford a mortgage

Households including at least one person with a high school diploma or GED can afford the typical mortgage payment in most large metro areas across the U.S., according to a new analysis by Zillow.

But soaring home values that have outpaced incomes have made down payments a barrier for many, particularly first-time home buyers.

Mortgage rates have dipped to multi-year lows in recent months, meaning monthly payments are relatively affordable for buyers who can secure a down payment. However, down payments are a challenge to afford for many as prices have grown faster than incomes over the past several years. An earlier Zillow study found that buyers need 1.5 years longer to save for a 20% down payment on the typical home than 30 years prior, and the difference is much more extreme in the most expensive metros – 13.3 years longer in San Jose, for example.

This effect is especially pronounced for first-time buyers who do not have the equity of an existing home to put towards a down payment on a new one. Zillow data shows that 46% of a typical down payment comes from savings for first-time buyers, compared with 35% for repeat buyersii.

"The influx of highly educated workers into already-expensive metros with stagnant or slow-growing inventory has made it difficult for those with less education and earning potential to enter those markets," said Skylar Olsen, director of economic research at Zillow. "There can also be considerable variation within metros. While a bachelor's degree may be enough to afford a mortgage on the typical home in the San Diego metro at large, it's likely to be insufficient in pricey areas like La Jolla. And that's only after scraping together a sizable down payment, which is a huge hurdle for most buyers."

For households that secure a down payment, the median mortgage payments are affordable for those with a high school education in 36 of the 50 largest U.S. metros. The remaining 14 metros require earnings associated with at least a two-year associate's degree.

The median income of a university degree holder is necessary to afford the median mortgage payment in the five most expensive West Coast metros. A bachelor's degree is typically needed in San Diego and Seattle, while the typical income of someone with an advanced degree is required in San Jose, San Francisco and Los Angeles. The typical mortgage payment is affordable for those with associate's degrees in Boston, New York, Sacramento, Washington, D.C., Denver, Portland, Riverside, Salt Lake City and Miami.

In only one metro, Oklahoma City, can those with less than a high school degree usually afford the typical mortgage payment. Households in Oklahoma City benefit from a combination of low housing costs – only three of the 50 largest metros have a lower median mortgage payment – and relatively high median incomes for households in which nobody has a high school diploma.

Median rent was 27.8% of the typical U.S. household income in Q1 2019. This is up slightly from the previous quarter and just below levels from a year earlier. Rent was most affordable for those in Pittsburgh, where the median rent is 21.4% of the typical household income. Los Angeles is the least affordable large metro for renters – 46.1% of the typical income is required to pay the median rent there.
