Accepted home sale offers in Massachusetts during November were up more than 20 percent compared to November 2013, according to data released Tuesday by the Massachusetts Association of Realtors. The association also reported the median price of homes placed under sales agreement was up 4 percent — from $316,000 to $330,000 — when compared to last November. Pending home sales in Massachusetts have risen for 21 consecutive months. Pending condo sales were up 9 percent in November, with the median price rising 1.7 percent to $304,000. The association also reported its market and price confidence indexes were both down in November, with the market index, at 49.54, dipping below the 50-point mark for the first time since March 2012 and the price index falling for the eighth straight month. On a 100-point scale, 50 is the midpoint between a strong and weak market. MAR President Peter Ruffini predicted a rise in November sales would move the market index upwards.
