I find it's good to keep the power on for the refrigerator; otherwise I'd have to clean it again prior to another tenant moving in.And I like to keep at least one light on when a unit is empty to give the impression that it isn't (empty).  

We will have to add a refrigerator, but that is all.  

We are opting to go with just a sink, refrigerator and microwave, not a full kitchen.

We have been told the carpet was cleaned 2 times and they were unable to get it up.Separate issue that may be related but unknown, in the living room and kitchen a slight black soot is collecting on some of the windows, ceiling, and oddly enough inside the refrigerator.

We don't want to spend too much, because we'll probably sell this refrigerator when we eventually get back into our house.  

There was also a water line for a refrigerator..... maybe someone forgot this is a 469 sq ft tiny house and fancy pants fridges with on demand water and ice take up precious floor space (and if they don't they are frigging expensive).Slightly annoyed, but still impressed.Then I swung by a week later.

Many houses now have "snack kitchens" in their family rooms -- a small kitchen with a smaller refrigerator, a bar sink and a microwave.  

For refrigerators and other major appliances it is within 72 hours.

I'm a journey plumber gasfitter and refrigeration mechanic apprentice so I'm come from experience.

@Greg Martin  I would suggest you go in and empty all the refrigerators.. the stench will be worse everyday it sits. and block fridge doors open, so they can air out,, pull plugs so if power comes back on they won't.
