I also quickly learned the language of construction and I was able to communicate my needs and wants much more clearly. 

Perhaps you should develop a menu of services and their price.

My guess is that given it is in such a great location the owner is intending to demolish it and develop something new.  

Learn a foreign language and move to one of these places?

This way if tenant falls out you can re-position and get another tenant in with finishing the build.I have had businesses before want me to do (be the bank) thing or just sell the land to them and want me to build the building for them for a developer fee.

I'd have to double check but I believe only once so far we've utilized a commercial note (shorter term and some language allowing a lender to use discretion, balloon terms, etc) and it was only briefly. 

Experienced in RE auctions, fix/flips, wholesaling, property management, project management & development on both residential and commercial properties. 

What I'm wondering is if people have language in lease or otherwise spelling out what happens if lease is broken.

I would suggest leveraging resources like BP and Google in developing your investment criteria, goals, objectives and constraints. 

I'm looking for lease language that says so and gives the landlord grounds to evict if they fail.
