If it persists, I would hire someone to clean it up and bill the tenant back.

If it means hiring local people, (I.e. cleaning, handyman, someone to act on your behalf in an emergency,) then where does that leave you if you’re only in it for a co-lister’s cut?

Then I told him if he doesn't know enough to even ask a full question, he probably doesn't have the reps to buy this now (obviously true and not debatable).

I did house hacking and still doing it and to start I hired a property manager to both learn from and to allow me to continue working full time until I was able to take over managing the property. 

If you're looking to make it easier on yourself, consider hiring a property manager.

I know its expensive but you will be well protected :)Or you save a lot of money and be better protected by doing this consistently and well:-carry appropriate types and amounts of insurance-sign contracts with indemnification provisions- obtain all necessary licenses and permits to operate your business-ensure all vendors/contractors are licensed and insured and list you as additional insured-sign well drafted and fair leases and be a responsive landlord -be an active owner or hire an active PM  who avoids or at worse timely eliminates premises liability exposure The strategies you often read about are sold by alarmist asset protection companies who fail to disclose how impractical they are.

What I would do is hire a licensed contractor for this work. 

You can cold call or hire people to marketing for you. 

You can do that much more efficiently via hiring a business coach or working with a mentor. 

I think many can be easily overcome like finding an attorney and contractors in the area, but the most interesting challenge I can think of is how to hire someone to deliver late payment notices one day a month.
