That will be a huge benefit as dealing with contractors is one of the hardest parts of the business in my opinion.

It's easy to do...

Yes I am familiar with all that you mentioned as I have several LLC's for my business and investment properties. 

I don't know if it's easy to switch as the LLC is newly formed, without any tax/income historyAny other way around re-financing?

I earn much higher returns than I ever did as a rental investor, and don't have to lift a finger after the initial vetting discussion.That said, some investors really do enjoy building a side hustle business around real estate.

That's not easy: most contractors don't like their tools or materials stolen.

I know a teacher who has a house painting business he runs on the side/ in the summer.

Should give you guidelines for properties and business plans. 

My goals are to learn from everyone here on a daily basis, improve my business/referral network (I’m a realtor), connect with other members in my area who may want to partner or benefit from each other’s skill sets, & ultimately become one of the many successful investors that I’ve read about.

Then compare against the cash flow after taxes from the business.
