My business partner and I mainly just work with investors here and we work with first time investors all the time.

DSCR will not work as they are business-purpose loans and you will have to sign an affidavit of commercial use. 

You are wise to limit your scope to a particular type of company.I have been in the industry for the past two decades, and from my years in the business, I can recommend a couple of other companies outside of my family. 

YOU are the expert in the kind of business you are trying to do.

I saw someone post in a group who I think is a schmuck brag about hitting a specific figure for their training and I just shook my head - like wow - this person is a great sales person and just steals the same lines from the business book about working hard and throwing out some slick slogans - but man oh man - when real estate gets hard people move to being a guru - just look at FB ads right now - many are not funds anymore but how to raise money, how to do X.

The answer is always no.LLCs are overhyped, especially for people starting out with buy and hold and are not even running a real "business" (yet).

In general, my overall feeling was that Doorvest is good if you're super busy and don't have time to really dig into real estate.

If I were in your position, I wouldn't worry until proof of the contrary because you should be ok if the business is running well.
