Here is what I would look for.
Dishwasher: stainless interior, DB rating 50 or under. Something with a pocket handle would be better.
Microwave: brands like GE LG tend to hold up better
Refrigerator: I would do a top freezer if possible for longevity or a side by side. The french door may be prone to service calls.
Ovens: self-cleaning, 5 burners, one with a backguard vs. a slide-in for a rental prob better, brands like GE, Whirlpool here.
