Probably doesn't happen often, but because it can happen, tough to get tile insurance before the 2 year period ends.Is it possible someone could buy without title insurance, sure. 

I'm hoping to install a doorbell video camera as well as maybe 1 or 2 exterior cameras.

.- Both boilers installed new 2017- Both electric panels upgraded 2015  - Shared Backyard access for bottom 2 units- No Parking, No Central Air- House built before 1900- Roof about 20Yrs old- Assume Fed cuts rate at least .25 point later this year Any thoughts would be appreciated.

I installed smart devices (Nest, Lock, Security System, Garage door openers, Blinds and others)  in my property before listing it on AirBnb.

For example if they did backsplash on the kitchen, make sure no tiles are cracked and there's no small little holes in the grout between the wall outlets.

The planning department says that once ADUs are installed, none of the units on the property can be rented for less than 30 days.

Even with an attributable labor rate attached to an invoice (which you have to trust a PM company to do fairly/accurately) it's still better than having them call a locksmith each time to rekey a lock or a plumber to install a garbage disposal.  

Also, if you have a handyman and a 6 foot concrete pad, you can have a bike rack installed for $60.

They were installed to code and are oversized for the square footage.
