Fewer existing homes were sold in central Ohio in October as compared with the same month last year. The Columbus Realtors trade association says more than two-thousand homes were sold in October, down by two-percent from October 2012. The group blames rising interest rates and a lack of homes on the market. Statewide, the Ohio Association of Realtors says existing home sales in October rose by 8 percent from the same month a year ago. And the National Association of Realtors says sales of existing U.S. homes fell by 3.2 percent from September to a seasonally adjusted annual rate of 5.12 million, the lowest level since June.
