House prices have skyrocketed in Portland, keeping many residents out of the market. That much is well known.

What’s lesser known: the gender wage gap in the city hits prospective women homebuyers especially hard compared to men looking to buy.

Women still earn less than men nationwide, and the real-estate site Estately decided to find out where that disparity most impacts women trying to purchase a house.

The site compared the median salaries of men and women in each of the 50 largest U.S. cities. Figuring that a doable monthly mortgage was 28 percent of income, the researchers “then used a mortgage calculator to determine the maximum home price each salary could afford.”

Next up, Estately’s data crunchers surveyed the houses for sale in the cities and determined the percentage of men and women who could afford to buy based on the median salary in the city for each gender.

Portland did not fare well. The only good news for the Rose City here: The city’s Northwest rival, Seattle, is worse.

Below, check out the 20 cities where, according to Estately, the gender wage gap most “impacts home affordability.”
