I do know one of these have been for rent for a few months but there are tenants in one of the other units.   

It would likely be in the 40ish unit range and would not be above 56 units. 

Unfortunately given the zip codes that you like, those units start with $800+ for single family homes.

projects we looked at were in Oregon and if your doing actual MH and your doing a larger project like 100 to 200 units it can take a few years to many years to fill them  and you usually need a mH dealer on site to sell them  etc etc.

We're interested in small B/C class multifamily properties (2-4 units) in the $200-$325k price range that has potential to reach 10% COC, with special interest in exploring hidden value opportunities via renovations/upgrades.

Is this divided by amount of units or is this amount for each unit.

This entails occupying one apartment while leasing the other units in a multifamily building.

We show many units without appliances and let them know we will bring in appliances if they do not want to provide their own. 

I think you may have very well narrowed down my strategy choices down to one of three; the BRRRR method (although this might be too much to start with for a newbie), the live-in flip that you mentioned (probably the most practical as I've been part of many different projects in the construction industry), and a combination of house-hacking/live-in flip (probably the most rewarding with a potential to swap between units as I finish one in order to bring better rental income).

I own single family, 2-4 units, mobile home communities, and some vacant land.
