One of them will eventually want to move out and I need to ensure the remaining two tenants can cover the rent.

Lenders who offer fix and flip products will almost always offer 100% of the rehab budget to ensure that the property reaches the ARV evaluation.

If it's just general move-out inspection, maybe some touch-up cleaning, then we'll force it vacant for 3-4 days to ensure we have time to handle that.

@Ken TsaiFolks like you  sometimes bring a private lender for a private lender and ensuring that they are aware; this is 2nd lien position for them OR make them part of the LLC and you are manager of the LLC. 

After researching the renter, I found they had a solid history of county licenses for the business and there were ongoing in-home checks through the county to ensure that the living conditions were in good order.

It is an option, but depending on the specifics of the circumstances, collections agencies may or may not be a very good option in terms of collecting money.I could be wrong, but I don't believe the police will assist, as evictions are civil matters and not criminal.I suggest to ensure good documentation of all the damage, written and photographed.

Do I have any rights or anything I can do to ensure that it is properly cleaned going forward?

You are required to use an unrelated 3rd party called the qualified intermediary to document the process, ensure that timelines are followed and take custody of the proceeds during the process. 

We're also making a choice to spend our money not on a sports car, or a vacation home, but on a luxury that comes with a large responsibility to ensure the safety of other people.

Things that I could add to it to help ensure a smooth first lease agreement.
