Occam's razor would say the neighborhood power outage was to blame, but I guess they thought we installed TVs, a refrigerator, stove, microwave, outlets and lights everywhere to trick potential guests into thinking we had electricity. 

I didn't even hear you mention a refrigerator. 

A few months later, the refrigerator breaks down at a property.

The leak was coming into the kitchen and on top of the refrigerator. 

WD 40-,  maroon or gray scotchbrite pad..... even strokes from top to bottom going with the grain of the SS ... follow the grain pattern since it may be different on the stove vs refrigerator......

Had a refrigerator go out.  

In your case that would mean buying a $1,250 refrigerator for $1,000 and then getting a 5 year warranty for $100.

I don't want to deal with property managers, let alone tenants who will get on my nerves by failing to pay rent or demanding a new stove, refrigerator, window, HVAC and etc., and breaking the drywall and kitchen cabinets with sledgehammer if I evict them for non-payment of the rent.
