FYI...I pushed on this exact point today. They flatly refused to change the language and told me the issue had been escalated to the company president.
We settled on having the seller provide screenshots of the dashboard and point activity statement prior to wiring funds at closing.
IMO, conditioning their "Buyer Assurance" on the use of an affiliated title company raises concerns under both Florida's timeshare resale disclosure requirements (Fla. Stat. Ch. 721) and RESPA's limits on affiliated business arrangements (12 U.S.C. § 2607) which require both clear disclosure and preservation of consumer choice. More importantly, the refusal to allow the buyer to contract directly with the seller, leaving the broker's affiliate as the only practical path for protection, strikes me as inconsistent with those requirements and with the standard language used by other major brokers.
