First REI move, Do you see anything wrong with my scenario?

[Murphy Kling]

Looking at making my first REI move. I currently have a HELOC on my primary residence, with most of that money tied up into paying off debt (will be 100% available next year some time). I also have a 401k that I'm considering rolling over into a SDIRA to use for investing. I have setup a LLC with the S corp election. Using that SDIRA, I see my self doing a 1 or 2 hard/private money loans on either flip, or multifamily rental. After that, hoping to grow a multifamily rental business.

Does anyone have any suggestions on what I think I want to do, or what I should do differently? 

I don't think this needs to be my first move, but, In the near future, I want to move out of my current primary residence (my first home) and turn it into a rental. I need more space and seems like it would be easy to do as long as I'm able to purchase that second home / new primary residence.

For the flips you may need a separate entity. But you probably don't need one when you just getting started. When your income starts to increase you may want to look at S-corp, it will help you minimize tax liability (but again, this is later on when your income grows). You can use this entity to adopt a truly self-directed Solo 401k plan and reduce your tax liability even more since it has high contribution limit of up to $58K/yr.
