The U.S. housing market, which saw strong growth for much of this year, may be starting to lose some steam, the latest Campbell/Inside Mortgage Finance HousingPulse Tracking Survey.

 “Expect weaker closed transactions due to increasing interest rates and higher prices,” added an agent from Nevada.
