I recently closed on a commercial condo unit (for retail), which is one unit in a building that also has 7 apartments. 

I am currently working on phase 2; building 2 ADUs.The permits are already in the works but the biggest question is what is the best approach when funding these 2 ADUs BEFORE I have the equity from my home?

As for building trust with sellers, communication is key.

Quote from @Franklin Marquette: When building ADUs, do they generally create value uplift for the property in the same way that the main house is valued?

Go to BUILD YOUR TEAM at the top of the screen and look for local investors or meetups in your area.

I sold an apartment building and as I lived in the building was always there when my realtor showed it to prospective buyers. 

I'm out of Fairmont MN also, been building a portfolio of apartment buildings in the area.

Or, should I focus on just holding these forever type deal and build a cashflow monster?

We've been continuously improving it, but it has been working exceptionally well for us since we hired a developer for the complete build-out a year ago.
