What’s Happening in the Market Now?

Looking back at August as compared to July, the number of new listings decreased, while the number of homes that went under contract increased. Note the red line in the graph below – its steady climb in recent months gives you an idea of just how active buyers have been in the local market. By the end of the month, the number of homes available for sale was nearly 30% less month-over month and 55% less year-over-year.

The absorption rate based on pending sales climbed to 110%, and the months of inventory based on pending sales dropped to just 0.9 months of inventory available at the end of the month. As a rule of thumb, an inventory level of less than three months indicates a strong seller’s market while an inventory level greater than six months indicates a buyer’s market.

The Mercer Island real estate market has continued to be very active this month, as September marks the beginning of the fall real estate season, the second busiest time for local buyers and sellers, after the spring market.

We expect to see an active market through October and the beginning of November before real estate activities settle down around the holidays.
