Well, I've lived without hot water for four days now, and I don't miss it at all. I soak the dishes well and use extra soap and extra elbow grease (and Heine's handwalkin' arms have elbow grease to spare).
I can give myself a reasonable "bath" with a wash cloth. And as some have noted, on a warm day you can wash with sun-warmed water, or just take a bracing cold shower.
I'll kill almost all the power consumers over at the main house and reduce the electric bill there to a few bucks. There are four ceiling fans I'll keep running to circulate air to minimize the risk of mold.
With the water heater dead over here at the apartment, my total electric bill may actually go down. In the past my bill here at the apartment-over-a-garage has run $50/month. I think I can drop that to $30.
Also I'm using a clothes line exclusively to dry my clothes. No more cheating with the electric dryer.
To people thinking of turning off their water heaters, I suggest NOT draining them. Draining them introduces air which will rust them out faster. (Even a drained water heater will still have a little water in it, which interacts fast with any air present inside the tank.)
I think I'm going to drop the property insurance. To hell with it. I'M the property insurance.
Fundamentally, my annual living costs without Mom's fat checkbook will increase by $2500 (property tax). The assessment this year for the 25 acres and two dwellings ($429,200) was exactly the same as last year, despite a huge decline in real estate values. So, that amounts to a massive tax increase in a time of falling incomes.
If I can't find someone to join me here in a permanent love embrace, at some point I'll auction the place off. Maybe come away with $250K free and clear. Who knows, maybe I'll move to the Philippines and mate with a "lonely Pinoy" and live on a beach, doing headstands and handwalks.

But I'm not abandoning my dear dog, so that would be five years down the line, roughly.
Not sure if I'll "get the girl." I'd like to, but she's heavily involved with her children, her church, and her career, and she lives a bit too far away. I have to be realistic about this.
Anyway, I don't have problems, I have opportunities.
