Hi, I am looking for an expert advise who is builder investor in mixed use.

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

Love the momentum you created with the right mix of education and action taking!

I am a coffee drinker however I prefer my own coffee (never can get the right mix of creamer and sugar) so I am not sure where you would like to meet to talk .

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. 

I don't really want to mix business with my personal life.

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

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