Ohio’s housing market is experiencing a fall sales boom, with sales of existing homes posting gains of more than 20 percent.

October home sales rose 23 percent throughout the state from the year before, and sales were up 20 percent in just Butler County, according to the latest housing report released Monday.

Real estate agents and homeowners closed on sales of 315 single family homes and condominiums last month in the county, not including the Warren County portions of Middletown and Monroe. A year ago in October, 263 local area homes were sold, according to the Multiple Listing Service of Greater Cincinnati, housed with the Cincinnati Area Board of Realtors.

The statewide gains surpassed those seen in May for the biggest year-over-year percentage increase seen to date in 2012. Ohio home sales surged 19 percent in May from the year before, according to Ohio Association of Realtors, now the next highest year-over-year gain behind October’s results.

May was the best month this year in Butler County. In May, the number of homes sold in Hamilton, Middletown and the rest of Butler County soared up 38 percent from May 2011.
