These units come with their own intake and exhaust pipes and the existing condition of your chimney wouldn’t matter.

Sometimes it will be disgusting rotten food, and worse.For the damage, take it out of their security deposit and if they are Section-8 report the damage to Section-8.For the missing rent money--can't get blood from a stone--try to find better renters--long term employed renters -- if you can.Good Luck! 

Some food for thought.

No griddle top means not going to be serving griddle food.

Use good tile, use larger tile with smaller grout lines and the grout color should be the lightest color of the tile.Make sure the tile is not slippery,  may have a little roughness in it and also that will be a little forgiving when the tenant spills coffee and food all over it. 

We are pretty sure they have a rabbit, and probably have a dog in the house,  but the inside of the house is well taken care of and did not see any real evidence other than cages in the attic and an empty dog food bag in the neighbors yard that has been vacant for months. 

Thank you for the comments, I think it would be best to purchase one and replace it even for the short term to avoid issues such as food spoilage. 

While people certainly gripe about increased food and energy costs, there are no nationwide cries to "cancel grocers" and most people that opt to stop paying rent are not likely to start stealing their food or gas.All that said, there are some pretty terrible landlords out there that do shady and illegal things, but they more than likely tend to be the smaller mom-and-pop landlords, which a tenant union is not likely to directly impact.

Plus offering food in the commercial kitchen you described.

This has boosted my confidence in taking this route, I really appreciate it.
