I'd love to figure out a formula that better incorporates this owner occupied value. 

@Jonathan R McLaughlin Hairdressers are a huge flight risk to sense if it’s going badly they can always go back and rent a chair somewhere else and get paid in cash

I incorporate an overage into my nighty rate to keep my cleaning fee on par with other properties around me.

With all the chairs (that never get used), ladders, flower pots, pressure washer, and much more, the area is not useable for anyone and maintenance of the area is so much more laborious having to move their stuff.

Well they used the space and built multiple gardens that will now need to be removed and there are some chairs and a workout machine/pull-up bar that was left as well.

The second time, they called the HVAC company and got the repair history as though it's their condo, using the info as background to insist on a new system before the repair person was even thereThey've texted dozens and dozens of times about everything they want repaired with photos and narrated videos, including:-chair cushions they think are too "high" to sit on properly (the place is furnished)-a wire shelf that doesn't have brackets holding it into the wall (which I said not to put anything on until the handyman comes, but they did and it broke, then they implied injury from heavy things falling)-kitchen drawers that are sticky, one of which broke, who knows if they got frustrated with it and slammed it open/shut-windows that don't slide like they are used to where they're from in Switzerland, so one is broken now-nobody coming to take the recycling bin 20 feet to the curb for the 2-story, 6-unit condo building (a service not in the lease); it overflowed and was unsanitary per photos; they offered to take it each week and I said "sounds great" but they still complain about it overflowingThey scared off my handyman with the same communication style when he tried to just set up an inspection time.

Also, there always needs to be some level of consideration in any agreement, so not a bad idea to incorporate a general release in the agreement as well.

I am definitely going to incorporate it!

Left an apartment full of furniture so I got some TV sets, microwaves, dining room chairs out of it.

Actually Deciding which use is "best", would incorporate all these items, plus budget considerations.
