Problem is I am buying a property and can't buy it inside of an LLC and would prefer to use a line of credit over using my own cash, but I know that this could be a problem, and potentially make it possible to "pierce the corporate veil" in the unlikely event that I might get sued. 

I tried looking at the state corporation commission for the registry of the LLC, but didn't see it listed in Utah.

If you time graduation when firms are hiring and your target school has companies looking for grads that they respect, a corporate gig that pays six figures or more is one fast track way into building high-level connections.

When I search there are some commercial NNN properties which are around or over $1MM with corporate guaranteed leases for atleast 10 years and goes up to 20 years (like Fast food Restaurant chains, Banks, medical offices etc).

I stand by my statement, and based on the few details provided here, it's more than just likely this space would not be a fit for a national restaurant tenant (either as franchisee or corporate signed deal). $1 psf/mo NNN ($12 psf/yr) NNN speaks volumes about the location from a national restaurant chain perspective. 

Yes, you can engage in construction projects in the US where a corporate entity is on the note, not the landowner.

Then corporate tax would be only the federal component of 21% max. 

Anyone had success with AirBnb or short term corporate rentals in Atlanta?

Between the annual reports and filing fees, and also the overhead necessary to maintain separation of assets so the corporate veil isn't pierced, the cost-benefit just might not be there.Might make the most financial sense (and most streamlined) to run her as a sole proprietor (Sch C) and carry appropriate and adequate insurance, which you should be doing anyway with an LLC. 

I just picked up a copy of “Start Your Own Corporation” by Garrett Sutton.
