The town of Foxborough saw a decrease in the number of homes sold in September, according to data released this week.

The data, compiled by real estate information firm The Warren Group, showed an 18 percent decline in September sales, from 11 to nine.

Year to date sales are down from 91 to 88.

Massachusetts had its third straight increase in home sales — up to 3,482 from 3,267 last year. This represents an almost seven-percent jump.

Warren Group CEO Timothy Warren said in a statement that the year-over-year comparison favors 2011.

"It's encouraging to see another month of sales increases," he said. "However, sales volume remains low because we are comparing to a period last year when sales dropped off after the tax credits expired."

"At this rate, it is almost certain that 2011 sales volume will be one of the slowest years in recent memory," he added.
