The Denver Metro Association of Realtors and the South Metro Denver Realtors Association boards approved a resolution to immediately dismiss all the board members of REcolorado, escalating a heated dispute among the three groups. REcolorado, the state’s largest multiple listing service or MLS, called out its two owners in the national trade press earlier this week for selling it to an out-of-state private equity buyer after rejecting a buyout proposal REcolorado had made earlier in the year that would have kept ownership in local hands. Four of the 11 REcolorado board members resigned this week in protest to the group’s action.
