Home Prices Rise, Falling Sales Suggest Prices May Have Peaked

High demand for a limited number of available homes continued to cause home prices to rise, but home sales fell in July. Three of four regions reported lower sales with the Midwestern region sales volume unchanged. Low inventories of homes for sale have increased competition among homebuyers; this creates bidding wars that cause artificially high home prices in high-demand markets.

In related news, The Commerce Department reported that new home sales fell by 3.40 percent in August. The inventory of homes on the market rose from a 5.70month supply to a 6.10month supply of homes for sale. Real estate pros consider a six-month supply of homes for sale a good balance between homes on the market and active home buyers. Increasing inventories of homes for sale suggests that home prices could be peaking as home buyers face strict mortgage rules and affordability concerns.

Hurricanes Harvey and Irma impacted 14 percent of building permits issued in 2016. While building permits issued may increase, ongoing concerns over labor shortages and building materials costs could become more pronounced as rebuilding in the hurricane zones progresses.
