If you have a lease with this tenant that allows them the dogs, you can still say they are in violation of the lease, I'll bet, by something in the lease that says they aren't to bother the neighbors or cause any disturbances, etc.

Leverage magnifies return. 3) The effort involved in adding an ADU is comparable or larger than a rehab associated with a BRRRR.

You must know something about it already, since you got involved in it. 

I never go off of a flat percentage on anything, I analyze the costs to get to a specific return I target and analyze the risk that is involved. 70% may be an initial metric to see if it is even worth pursuing, but every deal should be evaluated independently based on costs, time and risk involved.

Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers.
