@Andy Verge Dont worry in a few months $6.49 a gallon for heating oil will sound like a bargain . 

Be completely offgrid by installing a 2,000+ gallon water tank which will be filled by a company as needed, solar and wood burning stoves.

You  are not making money with $8/gallon gasoline in CA?

We were still able to cook normally with our propane stovetopWood-Fired Stove: not sure if your cabin includes a wood stove/pellet stove or if this is a feasible option for heatFilling the bathtubs with water before a winter storm: and voila you can flush toilets, include a big stock pot for warming up waterIf there's a spare small closet or cabinet you can lock (and have guests access via a lockbox) with winter storm supplies for your guests such as gallons of water, camp food packs, emergency solar/windup charger for phones, matches, etc to help them weather the first few days and save your booking that may be helpful as well.

Gas never got over $4 a gallon National Average.  

A couple of years ago, gas would be about $2.30 a gallon.

Specify what is excessive use (X more than $dollar amount per month, or more than x gallons/month, or unreported maintenance) Unreported maintenance meaning that the tenant had water leaking and causing damage under the kitchen sink and they knew something was up but failed to report it and now you owe a ton of money for water bill (and repair damages).

I don't know how handy you are, but I just bought a strong exterior gallon of paint, a 5 in 1, and some caulk.

It said we used 22,000 gallons of water last month.
