Inventory in Snohomish County soared 65 percent in October as compared to a year ago. The area now has 2.4 months of inventory, about the same relative supply as King County. As with most of the Puget Sound area, the increase in inventory was due to a higher number of sellers listing their homes and fewer sales. Year-over-year, the median price of a single-family home sold in October in Snohomish County grew 8 percent to $473,000. The median price in September was $485,000.
