You might ask why now?? The answer is that their are a record number of properties listed--mostly owned by investors and this will reduce prices, most experts say. The local housing market is still more robust than markets in many other cities, but having plenty to choose from have sellers and builders nervous. Data shows that 63% of homes for sale are owned by investors, many of whom got into the Boise market to take advantage of skyrocketing prices in 2005 and early 2006.
