Cash sales made up 33 percent of total home sales in June 2014, down from 36.3 percent in June 2013, according to a new report from real estate data and analytics provider CoreLogic. That is their lowest level since September 2008.

Cash sales share also fell month-over-month, dropping 1.4 percent from the 34.4 percent in May 2014. However, CoreLogic cautions that the monthly level of cash sales is affected by the seasonal nature of the housing market, making year-over-year comparisons a more useful indicator. The cash sales share has fallen year over year each month since January 2013.

Prior to the housing crisis, the cash sales share of total home sales averaged approximately 25 percent. The peak occurred in January 2011, when cash transactions made up 46.2 percent of total home sales.

Over 55 percent of real estate owned (REO) property sold during the month of June was purchased with all-cash, while 31.8 of all short sales were bought with cash. More than 16 percent of newly constructed homes were bought with cash, and 32.5 percent of existing home purchases were made with cash.

While the percentage of REO sales that were cash transactions remained high, REO transactions made up only 7.2 percent of total sales in June and, therefore, did not have a large influence on the overall cash sales share, CoreLogic said in a statement. In January 2011, when the cash sales share was at its peak, REO sales made up 24 percent of total sales.

Florida had the largest share of cash sales of any state, at 50.9 percent, followed by Alabama (48.1 percent), New York (44.6 percent), Kentucky (40.1 percent) and Nevada (40 percent).
