Abstract: A method of automatic check-in and facilitation of property related services is disclosed. A realty interaction server creates a property profile in a database, including a list of high interest prospects and a list of visitors. The server also creates a prospect profile, and automatically populates the prospect profile by querying a third party server using a prospect's phone number or email address. The server facilitates an open house check-in by processing an agent UUID and communicating at least a portion of the prospect profile to the agent and at least a portion of the property profile to the prospect. The list of high interest prospects associated with the property profile is updated using a predictive engine.
