Also, is there some prevision I can put in the lease to prevent the tenant from blocking the drive access to the ADU/Boat and from physically messing with my stuff, such as a fee.

Get that cluttered fairy tale stuff out of your mind and stop letting it distract you from all that matters, your 1 THING. 

Lots of rehab, lots of potential, and lots of cool stuff to do when I go to see the properties(hahaha).

Over doing this 30 years my experience has been that able-bodied applicants are turned off by that stuff in the shower.

People want a place to store their stuff AND park their vehicles.

A lot of the stuff I need to do is automated. 

And lastly, make sure the property management company has experience leasing and managing Section 8 properties, since there is a lot paperwork and processes, and I've seen experienced property management companies who do this stuff all the time, screw up on multiple Section 8 leases to where the tenant's packet expired because they were so incompetent.  

It’s small stuff that’s compounded: first they had a non-functioning vehicle dropped at the back of the property after they totaled it.

It was pretty much a nightmare because they were in near-east Dallas and they stuff we looked at was burglarized to the max.  

It's a complete disaster of direction.Your dad is a long-time investor and you are learning most of your stuff from books and podcasts?
