I've added him as an account manager in the account so that he can see the activity.

Any list you can pull for a few bucks has already been hammered by hordes of investors before you.Not saying this way can't work, but I recommend a different path...I prefer to focus on sellers who have a reason to sell but who require some effort and skill to identify.My favorites are #TiredLandlords, namely owners who have filed an eviction lawsuit against their non-paying tenants.Many of these folks are through being in the rental business and are open to hearing about a way out.Even better, #TiredLandlords are ideal candidates for seller financing, since they don't need the sale proceeds to buy another house, PLUS they are already conditioned to receiving monthly payments over a period of time.

Pair it with some local al-a-carte activity add-ons (partner with owners of these businesses Trap Shooting, Of Roading, Horseback Riding, etc...) and your rental can build its own niche

The one who owns the house will normally dictate who will report the activity on their return.
