As just one example of the real estate slump, Connecticut homes have declined in value in the past few years. Brokerage firms are using cash back rebates for buyers to stimulate sales of homes. The source of the cash is the broker’s portion of the sales commission. Typically, the seller’s broker gets 3 percent and the buyer’s broker also gets 3 percent. With cash back rebates, Connecticut brokers are rebating to buyers 2 percent of their commission.
