The Massachusetts Association of Realtors’ April Realtor market index hit 56.3 in April, an 86 percent improvement over the same month a year ago.

The index is intended as a measure of market conditions and is based on a monthly sampling of realtors.

The monthly Realtor price index was 59.8 in April, up 23 percent from a year ago.

"The index highs really resonate to a sense of improving confidence among the Realtor membership across Massachusetts," said Trisha McCarthy, MAR president.

MAR’s index is scored on a 100-point scale. A score of 50 indicates the market is neither strong nor weak. April was only the second time the index has been over 50.
