"Tenant agrees that the cost of professionally cleaning carpets will be paid out of security deposit at move-out, unless tenant hires and pays for a professional cleaner approved by land lord." 

I would also love to hear any insights and advice on the area or recommendations for some great local professionals(realtor, property manager, cleaner, maintenance/handyman)?

We have to constantly remind ourselves to be patient, we have unit one and it is going very well, just passed a year with it as owners and STR managers (And cleaners!)

Send them a list of stores that will rent them a steam cleaner, at the tenant's own expense, as per @Thomas S.Bigger picture: you may be creating your own monster. 

Hire a cleaner to clean the house, they split the cost like its a utility or lawn service. 

After owning gas for all our adult lives, our architect convinced us that induction cooktops were as responsive as gas and much, much cleaner.

@Matthew Cox The main person you will need to be successful is a great cleaner.

If your cleaners are using any of the modern apps, they can be integrated with your PMS as well. 

My cleaner lives next door and so far she’s been ok with using hers for the laundry. 

Professional cleaning w a surface cleaner.
