Freddie Mac is unwrapping a new set of incentives for its HomeSteps properties to both homebuyers and real estate agents this winter in an effort to pick up the sales pace of the GSE’s real-estate owned inventory.Through January 31, 2012, Freddie is offering homebuyers up to 3 percent of the final sales price toward closing costs while selling agents representing the owner-occupant buyer would receive a $1,000 bonus under the incentive plan.
