I completely agree with the advice and I'm perfectly okay with not charging him rent.My concern is that by treating this property differently from all the other units in the Series LLC, I may be opening myself up to a situation where I'm weakening my LLC protections even if I keep the financials separate and in order.

It all depends on the situation.

I am very interested from hearing from you guys that have experienced this situation.

I hope now that we exposed them, people, who are now in a similar situation will be able to identify this scam and not lose their money and credit over this.

Then if it isn't paid, you have unpaid rent and take action accordingly like you would for any other unpaid rent situation.

You haven't given many details so it's difficult to give you a quality answer for your situation.

If they decide to move out you can do the remodel. 3) are the tenants in any kind of financial situation to buy the property?

I would follow-up with a letter as others have stated, but if no action was taken I would trim off any branches that over hang my property eliminating my own liability in the situation. 

That’s before factoring in utilities or each personal situation.

When my places with section 8 tenants are inspected yearly the inspectors just want to be sure that the paint isn’t flaking and thereby causing a situation that a small child may ingest the paint chips.
