@Jun Lee Solo 401k is a great vehicle for investing!  

Long term buy and hold RE in good locations is probably one of the lowest risk investment vehicles IMO, similar to blue chip aristocrat stocks except even less risky because even long-established companies can go out of business but real estate very, very rarely ever goes to zero. 

It's not just any kind of car, and even if you buy the "right" vehicle, it has to be used 100% for business, which is rare.

LLC is a tax vehicle Not an asset protection vehicle for single members and or family type lLCs at least from what I see.

Love that you are learning more about the investment vehicle and that you are moving onto step two where you are working your investment criteria as well as networking with sponsors alike.

The Economic Development there is focused on building competitive regional talent, diversifying the regional economy, transforming Montgomery's image and building diverse community capacity.Major economic drivers to the area include Hyundai manufacturing, Maxwell & Gunter Air Force Base, major Amazon distribution, Alabama State Capitol, Alfa Insurance, Kinpak, H2 Pharma, Dollar General transport/logistics, Dow Chemical, and Conner Industries to name a few. 

For those reasons I see it quite remote that any state could come up with legislation to stop a sub 2 transaction or automatically call it.. there is already a vehicle in place to call the loans.. its up to the holder of the note to enforce it if they wish..

Finance was a combination of a few different vehicles and ultimately ended with a HELOC which was then used to fund multiple other projects over the years.

His dad doesn't own any vehicle.  

If you want to be completely self-sufficient, you're willing to build an Earthbag home or another building that can be earthquake proofed but can still be run without public utilities, you can spend a ton of money on a well and can have that well water processed to remove contaminated mine crap, you have a great off-road vehicle and you can figure out how to deal with the flooding without redirecting that water onto someone else's land then you can definitely live there.If it's an Investment you're after, give that up.
