I suspect it's more likely bad behavior.I would definitely notify the tenant of the complaints.

@Ellie Narie I believe what you are struggling with is a matter of perspective.Here is what I suspect you are contemplating: I have the opportunity to buy a house that would be a good rental property.

However, I suspect these $24K are on top of the regular PM fees and hence will only cover the on-site person taking care of day-to-day maintenance (cleaning, garbage, first-point of contact).

I suspect it varies on the enforcement, but I would certainly not plan on using the ADUs for STR. 

I suspect it wouldn't be hard to rent one if you price it correctly.

I suspect getting an unexpected utility bill may reduce waste.

The big thing is not to get hung up on rate, when you focus only on the rate you are suspectable to getting a worse deal than when you look at the whole picture. 

I suspect someone had inside information and knew the condition inside. 

I suspect if you look at the price of a home in Dayton or Cinci cira 1970 or so it will be darn close if not more than a similar sq ft home in Cupertino in those years..

If you say you want to keep the properties 20-30, I suspect you are building a passive income portfolio.
