When a marketing company refers a transferee to a broker and that broker lists the transferee's home for sale, the broker agrees to pay a portion of their commission, usually, 25% to 30%, to the marketing company for providing the broker with an opportunity to earn a commission. The brokers agree to pay the referral fee because they look to the marketing company as a continued source of business. Referral fees are also paid by brokers on inventory properties or when brokers assist the transferee in purchasing a property in the new location. Marketing companies use these referral fees as a source of income and may share a portion of the referral fees with the corporate client.
