The other thread on this topic also suggested serving and  referring the occupant to local charities. 

You need to be aware of your area laws as for as max occupancy goes.

You may want to add a clause to the lease that states that the fans are their for their use, but if they break, they will not be repaired .On another note, I have all my properties inspected by a professional prior to occupancy.

If you go the SFR route and are going to be taking a conventional residential owner-occupancy mortgage, entering with a partner isn't out of the question, but it will come with complications.

I selected other since it was owner occupant financing, but I should have probably selected the option with personal guarantee. 

However this can only be enforced where a dwelling has independent means of egress (not shared with other occupants).

You wait until the property is empty, spruce it up and then sell to an owner occupied buyer.Trying to mix the two strategies will not work, showing tenant occupied properties to owner occupants is a disaster.

They are talking about removing the occupancy requirement, but I'm not sure that will happen.  

In my market I know of only 1 lender who will do it for an owner occupant, and 1 other lender who will do it for an investor.

We have occupancy rules in the lease, along with a clear no smoking policy for tenants and guests.
