Likely the ADU was supposed to be a single unit hence the single meter.

YOU drive every single property before you bid. 

The main downside is the loan limits for a house with ADU match a single family, not those of a duplex (which is higher).

Welcome to 17 Penny Lane, a charming residence nestled in the heart of Walden, NY 12586. This delightful home ...

I live East of Columbus, OH and have been looking for single family or small duplexes in the area.

If you can qualify using your income I would avoid DSCR but again its not the end all they have value.DSCR single family requires 15% down, 2-4 Units require 20% down, they offer 5/6 ARMS, 30 & 40 Year fixed and I/O Interest only options which can help cash flow first few years.

Are they owned out right by a single person or a family?

If you need a single-member LLC operating agreement, you don't need to overthink it to start.

Hi  Team,  I have two  properties under contract ( single family homes).

I have enquired with lender about in shifting title to a single member C-Corp, but they don't allow it "Bank’s charter does not allow it to purchase or own loans where the borrower is a corporation"
