Mortgage rates at a 4-year high could be weighing on America's housing market.
Mortgage applications dropped last week for the fourth time since mid-March, down 0.2 percent, as the average 30-year fixed loan rate rose to 4.73 percent, according to the Mortgage Bankers Association.
The trend raises the prospect of more buyers being squeezed out of the property market amid rising prices and the limited number of listings.
