The last time I stayed in one, I was charged a large cleaning fee and then met with a list of what to clean prior to us leaving.

By all means give them a note on how to use all of the appliances (eg clean out the lint trap on the drier after each load, do not use dish soap in a dishwasher, change the furnace filter regularly, etc).

Instead of flipping the house, I should have wholesaled it—cleaning it out and listing it for another investor to take on the renovation.

Keep the property clean, updated and rented to good tenants.

I just set up my vrbo account and still some finer details about planning the communication, cleaning service, maintenance persons, etc…

Soon after I built the car wash, I was evicted from my leased space where I waxed and cleaned cars. 

For example, to get up-to-date property tax data you would need to scrape every county's tax data website (thousands of different websites, data formats, issues, etc...) then aggregate and clean the data.

so... clean-out and demo? 

You'll likely want someone that can handle A to Z with marketing, pricing, cleaning, maintanence, decor, websites, reviews etc.

I have to go back in and clean things up because the property management company numbers are different from what's in my account.
