You probably don’t need to be convinced that housing is too expensive in Seattle and King County. But the numbers put a fine point on it. Earlier this year, the median home sale price in King County surpassed $1 million, far out of reach for most residents. Renting isn’t so affordable either. Fair-market rent on a “modest” two-bedroom rental is $2,645, according to the U.S. Department of Housing and Urban Development. A household needs to earn more than $105,000 a year to afford that without being considered cost-burdened.
