Some of my first guests left cooked food on stove others left it really clean.  

One of the slogans I hear bandied about is that "one shouldn't have to chose between rent and food."

I don't disagree that Facebook is a lot of morons posting pics of food they're eating but those morons are your new tenants!

Just as a side note, the stovetop pizza makers use baking stones on the interior to hold heat better and radiate it back out to the food. 

Just food for thought ....

I would like to know how should I start the process to find out potential tenant(fast food,Bank etc).

The food here is incredible, and cheap.

You’ll need to sell some food, sandwiches, muffins, etc  too I would think....coolers, display cases/coolers, dishes, dishwashers, supplies, costs for labor, rent, utilities, insurance, licenses, permits, inspections, etc, etc.

That is going to be relevant to how in-demand your market is (which I have no insight on) but just food for thought before you panic too much. 

It had food exploded all over the kitchen walls & ceilings as the owner would simply heat cans of food on the decrepit gas stove.
