One property we bought had four major roof leaks and blue tarps and cinder blocks on the roof. 

Mentorship is crucial for structuring the Letter of Intent (LOI), due diligence, and financial analysis.

Put up a block foundation and have a house mover slide it into place.

You can probably have a friend do it, and have him sign a letter attesting.

I would even venture to guess that it is not a simple letter to the lender or trade that gets a lien release.   

I would structure the lease as a corporate lease to the company, if the company wants the lease in the occupants (employees) name make sure to get a letter of responsibility from the company stating that they're financially responsible for the rental agreement. 

The carrier may issue a "reservation of rights" letter and ultimately deny indemnification; but generally they have a duty to defend.   

@Andrew Postell I too am having brain blocks to this post and am really looking to understand.

Or should I talk to him and ask for additional security deposit since we received the bankruptcy letter?

If you put it out there asking for a 3-5 year lease with a small business or startup in your mind, but H&R Block or Supercuts comes along asking for a 10 year NNN (& it's corporate) and agrees to the rent amount you requested, there's no reason not to entertain that, you got better than what you were expecting (there's a reason NNN properties, or ones with a few NNN tenants sprinkled in that are national chains, often sell for lower cap rates), it's not like taxes or hair cuts are going obsolete any time soon.
