If the ground is clean, they are less likely to litter.

I included in the proposal the benefits for the landlords, such as no worries for vacancies, a 5% profit share on top of the rental rate and the provision of a professional cleaning team for their property.

If someone asks if it can sleep 12, I don't charge for that either.I would either just charge the guests more for the cleaning or if you offer free cleaning, add it to the nightly rate.

If the tenant identifies an area of moisture that may be causing growth we immediately address the source of the moisture, replace and damage building material (usually dry wall) and or use mold cleaning solutions/mold blocking primers as required. good luck

- Do you clean the entire unit after the one tenant moves out?

Long terms rentals will have repairs from time to time, but if it is a true emergency, you are going to be calling someone (eg plumber) to come in and fix something, so that is no different than your own home (minus the clean up). 

This fee helps cover cleaning and paint touch-up costs after tenants move out.

A good cleaning will make it pop brighter and couldn't hurt. 

Clean up the cities is something the fed can do..

Or, dog bowls, dog treats, toys, doggie bags for mess clean up in yard, etc.
