"The commercial real estate is business-focused real estate which involves property that is sold, leased or used to achieve a predetermined business objective.

You should have an AUTOMATIC "extension" clause fo anadditionalr one year in the event you don't exercise and you should offer to deposit more cash (pre-determined) to owner within 10 days before/after of expiration date as goodwillI IMPLORE you to make sure you get your name on title OR and legally record the option agreement at the county recorder's office or file Notice of Pending Sale against the title.

It's a bit complicated, would involve renting the property until an event occurs at which time I would purchase at a pre-determined price.If we come to agreement, it will take some time to get everything drawn up properly to protect all parties.This may just be the one I've been waiting for!

A mortgage pre-determines even payments so that principal+interest pays the loan off in a specific amount of time. 

Could you please go find someone else’s post who enjoys your ******** thank youYou just shot yourself in the foot, by having your own pre-determined "target market"!

And are there any pre-determined guidelines around liability? 

You need to ask what the current occupancy, current noi, current expenses and ask for whether or not they have a predetermined cap rate.

When you have 5-10 years lease with predetermined rent bumps, how would the "potential rent" be relevant?

This is referred to as an option to purchase.A potential buyer can enter into a contract with the homeowner whereby the buyer has the right to purchase the property up until the predetermined option date at a predetermined price.  

Also, each payday, a predetermined amount of money gets transferred into savings.
