I think if you were sharing walls or in same house, then certain quiet hours in lease or noise restrictions can help prevent some issues. 

There may be ways to share space but give the impression of a separate unit (such as an unpermitted wall up to create separation). 

In my area, not only is there zoning regulations, but building regulations where 3 families are built to different building standards, such as cement walls for boiler rooms, sprinklers, fire escapes to name a few.

Is changing a broken wall plate a "service" according to this section?

That shouldn’t be too hard either because the kitchen and bathroom are right next to each other only separated by a wall (would just need to figure out the hose bibs). 

I do think everyone has a different experience, but that's often colored by how much they are invested.

Things to look out for are old windows, old wood siding, peeling paint on exteriors and interiors, and damage to window sills, door frames, and walls.  

There are also limits to what does/doesn't need a permit, so attempting to find properties that don't require walls to be moved or other issues that may require a permit would be helpful too in the interim.

Another idea is to do an Instagram wall on the lanai..have a mural and maybe a neon sign (some people name their house) and you can put that in neon and have people tag your house and help them advertise for you.
