If the tenant has no identifiable support network, call your area's Adult Protective Services and let them know the situation - they may not talk to you until you own the property, in which case have the seller reach out first. 

Hey @Julius Jones,I'm an independent agent and almost exclusively write multifamily.

That's the competitive advantage exclusive to this biz.

I have no clue what they have put in place locally.For instance there is a Standard of Practice nationally that says:Standard of Practice 16-13All dealings concerning property exclusively listed, or with buyer/tenants who are subject to an exclusive agreement shall be carried on with the client’s representative or broker, and not with the client, except with the consent of the client’s representative or broker or except where such dealings are initiated by the client.If found to violate that they could face a fine of up to $10,000 depending on what side of the bad the hearing panel woke up on.

I'm also moving from one unit to another unit in order to maximize the prorated amount of my occupancy so I can maximize the $250,000(single)/$500k (married) residency Exclusion of capital gains tax.

So I'll continue with the current batch and not keeping adding new entries so I can focus marketing dollars exclusively on doing multiple touches each. 

Some brokerages almost exclusively wholesale.
