Have them leave cupboard doors open below the sinks to let in extra heat and you need to check on the place every couple of days to make sure it is warm enough in there. 

You open a cupboard door.

Guests staying more than 30 days are likely going to cook at least some of their meals, and nothing ruins a stay faster than opening up the cupboard to discover worn, dingy, and damaged cookware.Best practice: Buy a new, inexpensive yet COMPLETE set of cookware, containing at least a frying pan, a covered skillet and two sauce pans.

Tenants move in and shortly thereafter water appears coming through the floors damaging floor boards, cupboards, etc. 

What you're planning to do is run it like a boarding house.You'll want to confirm with the local municipality that this is allowed.These are actually fairly easy to manage while you are living there and self-managing.Once you move out though, it is more difficult:(Occupants will be sharing a lot of common areas NOT usally shared in a separate rental: fridge, stove, cupboards, bathrooms, furniture, etc. 

When I checked cupboard on arrival 3 loaves of bread had been there at least 2 weeks in Texas heat and the smell was putrid 2.

I took it down, deep cleaned the unit, added handles to the cupboards, and purchased a Modem and added internet for $30/month. 

The pantry is a cupboard on the reverse wall of the kitchen, so you have to leave the kitchen and walk into the hall to access it.If you are accessing the house from the actual front door, it's a pretty standard entry.

I've seen this type of layout before what was done when the kitchen needed to be remodeled was a small piece of counter (maybe a foot or less was added on the other side of the stove with a cookie sheet type cupboard underneath. 

The bathroom, that one I think needs some major makeover and also the kitchen area (cupboards look old and unsightly) so if I'd do repairs, most of the expenses would go into these sections.
