Clark County housing inventory a bit better But demand still outweighs supply as prices climb Published: February 16, 2021, 6:04am Share: 3 Photos New homes under construction in the Parkers Abby development in Vancouver in January. Clark County's housing market is experiencing record high demand, with bidding wars on virtually every listed property. (Amanda Cowan/The Columbian) Photo Gallery Clark County finally saw a slight improvement in its supply-constrained housing market situation in January, according to the latest report from the Regional Multiple Listing Service. Southwest Washington’s inventory in months — a measure of how long it would take to sell through the existing supply of houses on the market — rose from 0.6 in December to 0.8 in January. That’s still a near-record low, but it’s the first time the number has increased since August.
