my 2 cents are most commercial properties can be very niche-y ex multi-fam, retail, industrial etc. Anyone who does "wholesale" or more known as a "crossing the trade" in the commercial space is going to want to know some similar thinfs as residential wholesalers as is value, price the seller is willing to sell at and if they are open to terms like seller financing, what kind of work needs to be done to bring it up to its best use or the use changed to be able make better use of the land or property.
The other thing that i would want clarified is it the business or the building that is for sale. Because in this situation that could be both in which case that would mean it is going to be a whole different set of things to consider like how much the business is worth and how long the seller is going to stick around to help the new buyer get situated. And evaluating a business for wholesale is going to have a whole different type of buyer as well.
Hope that helps!
