Realtor confidence in the housing market dipped slightly in August after hitting record highs earlier in the summer, according to a new survey from the Massachusetts Association of Realtors (MAR).

MAR’s Realtor Market Confidence Index (RMCI) and the Realtor Price Confidence Index (RPCI) were both up compared with the same time last year, but the RMCI declined in comparison with July. 

In August 2013, the RMCA was 69.26, which was up 23 percent from the August 2012 score of 56.41. This is the 25th straight month of year-over-year increases, but the first time in six straight months the RMCI has dipped under the 70-point mark. On a month-to-month basis, the August RMCI was down three percent from the 71.09 score in July 2013.

The RPCI was 73.57 in August, up 15 percent from the August 2012 RPCI of 64.19. This is the 19th straight month of year-over-year increases and the sixth straight month over the 70-point mark. On a month-to-month basis, the RPCI was up two percent from the July 2013 RPCI of 72.27.

"We continue to see significant year-over-year gains in Realtor confidence in the market as we have for the past 25 months," Kimberly Allard-Moccia, 2013 MAR president and broker-owner of Century21 Professionals in Braintree, said in a statement. "Considering that inventory continues to be down and interest rates have been ticking up, buyer and seller activity continues to push Realtor sentiment in a positive direction."

Realtors don’t appear to be too worried about the impact of the recent rising in interest rates. MAR asked its members how the increase in rates has affected homebuyer activity. Thirty-seven percent of respondents reported that they saw either a significant decrease (6.6 percent) or a decrease (29.5 percent) in homebuyer activity. Thirty-nine percent reported no change in homebuyer activity, while 25 percent reported seeing an increase (19.7 percent) or a significant increase (4.9 percent) in homebuyer activity.
