There is also one big issue with your tax projection - the taxes of $280 are based on the vacant land taxes and will likely go up to ~$2000-$3000 in a year or so when the assessor catches up with you.I realize there is a 1031 involved so a real estate purchase is necessary, but you should compare your ROI to a safe yielding instrument like a 10 year T-note or AAA corporate bond yield. 

It just looks like another corporate guru trying to win your business.

The only reason I'm hesitant to move forward without this info is that the seller is an inactive corporation - if they dissolve and there are issues with their warranty deed then I don't want to have to pay a lawyer to go after the GP of the defunct partnership to make me whole.

If something really bad happens,  the lawyers would "Pierce the corporate veil" of those LLC's to get to your assets anyway. 

This means that you will probably need to pay registration and filing fees in at least 2 states if you don’t buy CA property as a CA resident.Any lawsuits should be limited to the assets of the LLC and not your personal assets (assuming you run the LLC appropriately and the corporate veil is not pierced, some debate as to SMLLC).

If this is a large corporation it may make a difference, or if the landlord was that bad and a point needs to be made, then maybe.

Borrowers will want to check with their mortgage broker or banker on any limitations to ensure the note cannot be called if transferred to a corporation. 

I have tried a couple times to get ahold of someone to do this, but I haven't been able to get much traction--I will admit, I quickly get distracted with other things and forget to follow up.Is the right way to go about this just pure persistence, or have others had success buying from large corporations like railroads?

IE a corp or LLC etc..

My wife and I were working full time corporate jobs where she made 6 figures, and me a bit less.
