WASHINGTON - Seattle's housing market will likely remain a seller's market in the future. The housing market in Seattle had only 0.3 months of inventory last year, which was below the level needed for a buyer to secure financing. Despite the lack of inventory, the US housing market has been experiencing record low mortgage rates. Moreover, the supply of new homes on the market is limited, and the construction industry suffers from a labor shortage. This combination of factors can make it extremely difficult to sell homes.
