Realtors’ confidence in the housing market declined for the first time in over two years, according to a new survey from the Massachusetts Association of  Realtors (MAR).

MAR’s Realtor Market Confidence Index (RMCI) was down eight percent in November, slipping to 56.8 in November from the 62.02 score in October 2013. The index was also down almost 1 percent year-over-year, with the dipping from 57.3 in November 2012 to 56.8 in November 2013. That’s the first year-over-year decline in 27 months.

However, Realtors’ confidence in further price increases was more mixed, with the Realtor Price Confidence Index (RPCI) falling to 70.6 in November from 71.5 in October. Year-over-year, however, the price index was up from 67.5 in November 2013, the 22nd straight month of year-over-year increases.

"The market has been on a good run and the Realtors’ confidence has reflected that over the past two years," 2013 MAR President Kimberly Allard-Moccia, broker-owner of Century21 Professionals in Braintree, said in a statement. "Despite the small dip in the index in November, the fact that a majority of Realtors who responded to the survey are optimistic about an increase in inventory is a good sign for the 2014 market."

Realtors were also asked about their thoughts on inventory heading into the new year, and the majority feel the extremely tight conditions of recent months are likely to loosen. Fifty-seven percent of those who responded believe that the number of homes for sale will go up in 2014. Thirty-six percent of the respondents believe the number of homes for sale in 2014 will be at the same level as in 2013. Seven percent of the respondents believe the number of homes for sale will go down in 2014 while no respondents believe the number of homes for sale will go down significantly next year.
