Since this situation was so egregious (IMO), I would either boot them out now, or at least have a serious talk, real serious....If you're going to let them stay I would just get a really deep cleaning done, maybe a couple, and then replace carpet after they're gone.

We upsell 3-to 4 simple packages that guests love; I have trained my cleaners to handle them (they make extra money), my VAs help schedule it with cleaners, and we still make a 50% profit margin on everything.

Experience depends on who you deal with - the cleaner the loan file and more organized your paperwork the smoother the process with any private lender.

Any contacts in setting a good team of contractors (general purpose) and cleaners?

I self manage, have a cleaner but I also sometimes turn the unit myself.

It also makes things cleaner with other potential heirs. 

Remember you will also need help with set up, hosting and cleaners. 

Example of what a tenant might say - this 2x2' stain on 2 year old carpet was already there when I moved in.  

They knew a dog lived there when they rented it and they rented anyway, knowing they had allergies and chronic asthma they rented a home with carpet. 

Most likely due to wanting to invest his time more wisely:)If you can move in with family or friends RIGHT NOW and rent out your house and start DIY managing it BEFORE moving out of state, that would be best.Otherwise, handymen, cleaners, agents, etc. are highly likely to take advantage of you once they find you you live OOS.
