(CNN)– A federal judge gave final approval to a settlement that will have a big impact on the real estate industry. Groups of home sellers brought lawsuits against the National Association of Realtors for its standard commission structure, saying it was a violation of antitrust laws. The real estate trade group reached a deal to settle back in March. A judge granted preliminary approval to the agreement in April and final approval was on Tuesday. The $418 million settlement also includes rule changes related to agent commissions which took effect in August. Categories: News
