About ReferralExchange

Our goal is to eliminate the time and aggravation surrounding the outbound real estate referral process. We’ve been connecting agents and clients together since 2005, and have helped sell over $5.3 billion in real estate.

We help agents make more money by allowing them to focus on leads within their area and preferred property type - while still earning a referral fee on the leads that aren’t an ideal fit. And, we help match buyers and sellers with the best 3 agents who fit their needs. We handle the entire process - from client verification, agent matching and follow-up to ensuring everyone gets paid.
