An unseasonably mild March gave Maine’s housing market a needed boost, with both sales volume and median price up significantly from a year earlier.

Sales of existing single-family homes increased 14.6 percent from March 2015 to 1,089 sales, and the median sale price increased 7.4 percent to $182,500, according to a Maine Association of Realtors report issued Wednesday. The median price indicates half the homes sold for more and half for less.

In February, single-family home sales grew 21.7 percent compared with a year earlier, but the median home price fell 4.4 percent to $160,000 over the same period.

Association President Ed Gardner said in a news release that conversations with real estate agents around the state indicate that the market was brisk in all price ranges with many situations in which multiple buyers competed for move-in-ready homes.

“The latest statistics indicate a healthy real estate market statewide this spring with most counties showing year-over-year improvement in number of sales and increasing values,” said Gardner, owner and broker of Ocean Gate Realty LLC in Portland.

Sales in the Northeast region were up 7.7 percent in March from a year earlier, and the median sale price of $254,100 reflected a 5.8 percent increase, according to the National Association of Realtors. Nationwide home sales were up 2.6 percent, and the median price was up 5.8 percent to $224,300, the association said.

Maine home sales for the three-month period ending March 31 increased 16.4 percent from a year earlier to 2,869, and the median sale price increased 5.4 percent to $174,500.

Washington County had the biggest increase in home sales for the three-month period, up 71.4 percent to 72 sales. Only three of Maine’s 16 counties had sales decreases: Aroostook (12.1 percent), Waldo (9.2 percent) and Hancock (4.2 percent).

Waldo county had the biggest increase in median sale price for the three-month period, up 11.2 percent from a year earlier to $129,000. The biggest decrease was in Aroostook County, where the median price fell 11.7 percent to $66,250.
