Sales of previously occupied U.S. homes slumped in October to their slowest pace in more than 13 years as surging mortgage rates and rising prices kept many prospective homebuyers on the sidelines.

Existing home sales fell 4.1% last month from September to a seasonally adjusted annual rate of 3.79 million, the National Association of Realtors said Tuesday. That’s weaker than the 3.90 million sales pace economists were expecting, according to FactSet.

The last time sales slumped this hard was in August 2010, when the housing market was in recovery from a severe crash.

Sales sank 14.6% compared with the same month last year. They have fallen five months in a row, held back by climbing mortgage rates and a thin supply of properties on the market.
