SOUTH PORTLAND – Maine’s real estate market remained strong in October despite concerns about the economy in the wake of the terrorist attacks.

The Maine Real Estate Information System said sales grew 2.3 percent compared with the same month a year ago, and median sales prices increased 11.3 percent.

Low interest rates were cited as the main reason. The upward movement was not universal.

Oxford County saw the biggest percentage gain in sales and in median price. But sales in Somerset County were down by 36 percent. The median price for a home in Maine last month was $128,000.
