Clean, functional, well priced units rent quickly regardless of whether they are 1BR or 2BR.

Functioning toilet and shower.

In general for a traditional loan, it needs to be a complete and functional home absent safety hazards. 

The inspectors gonna say yep the cabinets function and no water damage under the sink.

I'm not sure what county you actually mean by Willamette County (assuming you meant our Willamette Valley, which is made up of several counties) but I looked into this in Clackamas county recently and the kitchen size allowed in a 600 sq ft ADU on a 5 acre lot didn't really allow for a fully functional kitchen, more of a kitchenette or maybe motor home sized appliances.

I like the class functions they you could segregate costs by unit, building, and even geographic locations, such as NY vs MA, through the use of classes, subclasses, down 10 levels.At the same time, I also did accounting on the side for a government funded non profit that that I use classes to segregate funding sources.

It's clean and functional.  

Reading will help and networking functions will definitely help your education. 

I'll get a higher IRR with less headaches and risk by having 20 doors that pay $2000/m in a gateway market, but those details are rehashing old threads.Point being: I'm invested in our market because of the long term appreciation, which is largely a function of our public policy and desirability. 

The biggest issue in the units is functionality.
