We have an excellent team of cleaners handyman and other local professionals and been in the business for five years.What are the costs vs benefits of each platform?

If you can do the deal yourself safely, with reserves to cover unexpected issues, it is a lot cleaner.

Reliable Cleaners will make or break your success with short-term rentals, so that is a must.

After/during the transaction, I give them my contacts that they may need such as a cleaner, contractor, property management, etc. 

I manage my own STR and have one cleaner to do the turnovers.

There's no such thing as cleaner energy?

There are lots of rental management companies, and finding a good cleaner and support person is possible. 

interview and find a great cleaner.

So outsourcing some degree of property mgmt would be a must... but the deal won't work paying a local property manager a large % of my revenue...Instead, I would set up my "boots on the ground" (cleaners, handyman), and would need an offshore virtual assistant to manage guests and coordination of my local team. 

At move outs I always hire cleaners and bill accordingly from their deposit, then go over it again my self before showing.
