Median listing price: $688,000
Percentage of households that can’t afford a home: 57.6 percent
Seattle’s median listing price of $688,000 is among the highest on this list. However, the percentage of households that can’t afford a home isn’t as high as in other big cities because the median household income here is high — $83,476. It’s not high enough, though, to comfortably pay a monthly mortgage of $2,911 on a median-priced home. You’d need an income of $116,440 to afford a home in Seattle.
