My view is the ADU budget needs to be doubled if the OP is not going to actively work the ADU addition.  

Tell me how often you have to file for an eviction.I didn't ask to negotiate the monthly fee, and never have since day one - as long as they provide me excellent service, I am happy to pay their requested rate. 

Also, any investment interest expense that ensues from passive activities typically does not qualify for deduction either.

I found a nice one listed 475k with on active unit at 950/mth and 8 empty units in need of repair.

I live in Portland, Oregon where the tiny house movement is pretty active, and zoning laws for tiny houses are quite progressive.

. $840 a door for 10 unit building, and we are doing a little over $300 per door on the 34 unit with capital returned, and debt services on both.We are fully vertical company. 

I am actively looking though.

I've helped to convince a couple tenants to get signed up for these services which helped them be able to afford a bit more in rent.   

General contractors typically charge a percentage for their service.

However, I want to scrupulously respect BP's forum rules and, anyway, I'm active in the forum to help, not to sell.
