One of the best real estate referral networks is ReferralCloud.

ReferralCloud is a network of real estate agents that give each other client referrals. Their unique selling proposition is that in addition to a 25% referral fee, the agent gets the next client referral in their market.

The ReferralCloud network is free to join and gives real estate leads paid at closing.

ReferralCloud is also a great Opcity alternative.

Another advantage of being an agent in a referral network is that agents can get real estate leads from other agents in the platform in addition to collecting referral fees from their outbound referrals.
