If needed, update faucets and replace all hoses, pipes, washers, seals, etc. if I do.26.

-"Replaced" the broken washer & dryer in one of the units with used units without my knowledge until I saw the monthly bill.

The sassy one said it was her "dead friend's" - I'm pretty sure she thought she could guilt me into not doing anything about it, but I reaffirmed my stance by saying "It's your cat now, you can either get rid of it or pay the fee."

There is one washer and people don't use the dishwasher.

If I was here for the purpose of business absolutely. 

Ya, put it in a secluded spot, with a campfire right outside, some nice chairs, maybe a hammock, some bicycles if there are little roads or baths to ride down, Frisbee, horseshoes, washers, or whatever people like out there.

Do you know how much electricity a washer/dryer typically uses in a year?

The washer would fill, agitate and then not drain.
