This is a great place to learn and to connect with people so take advantage of all the great resources.

Deal sourcing- if you’re willing to search regionally, don’t ask anyone to sell that isn’t already in a sale mode. “ No marketing.”

You should only have to do this with the largest items- mainly couches/chairs and dining sets.

A 5 year arm might be a bad idea in this case. 

In my experience, you are thinking through this correctly.I've heard lawyers say, if the loan is in your name (which it has to be for conventional) and the deed is in the LLC, you aren't treating the business as an independent entity and in a severe lawsuit, the corporate veil is pierced and the LLC can be thrown out.I agree that one of the best defenses is to run your properties well. 

While this brokerage would start in Ann Arbor, I would want it to expand to all of Southeast Michigan, then statewide, and ultimately nationwide.As flippers/investors, would you be interested in listing with this brokerage?

I would like to start using social media, in particular YouTube, to market my business but I know very little about it.

Im open to conventional financing or seller financing.To find properties, you can network with local agents and brokers, join local real estate investment groups, use online platforms like Zillow, Realtor.com, and Redfin, send direct mail campaigns, drive for dollars, network with property managers, and explore seller financing.Good luck!

While this is less tax efficient, it would be less work / less stress.

I'm sure there must be someone in your network that is successful in this.
