Right now, my mortgage is around $2870/mo, which includes property taxes (about $4800/yr) and insurance (about $1300/yr). They screwed up estimating my property taxes and didn't take enough out initially, so for the time being my payment is extra high, to boost the reserves. I think it's set to go down by around $150/mo around September/October, when they reconcile.
The principal/interest portion of the mortgage is about $2220/mo. The electric bill is averaging around $200/mo. I've been in this house since September 2018. Cheapest bill I've had was around $120, and the worst was $265. Heat is provided by two heat pumps, one for the upstairs, one for the downstairs. The downstairs unit has an oil backup, while the upstairs is all electric. I had the oil tank filled up about a month or so ago, and it cost around $380. Last time I'd had it filled was February 2019, so that one tank lasted about 14 months, and took a little over 200 gallons. The 2019-20 winter was a bit mild, though. As a reference point, the house is about 2400 square feet, plus 960 square feet of basement. The basement is heated/cooled, although not that effectively. It also has what I guess you'd call a 3-season room, which is maybe another 430 square feet. It's closed in, finished off, and has electricity, electric baseboard heat, and a big window a/c. I might run the a/c every once in awhile in the summer, but never turn the heat on out there.
I'm on well and septic, so there's on monthly or quarterly bill for that. However, I do have to throw salt in the filtration system every once in awhile. It comes in 50 lb bags, and is around $6/bag. There's also some other chemical I have to add every once in awhile, but I forget its name, and don't feel like going down to the basement to look it up right now.
I have a swimming pool service, and they charge around $400 to open it, $95/week to service it, and around $400 to close it. I could probably handle a lot of that myself, but I'm allowing myself a splurge, there.
So, for a rough estimate, I'd guess the house is costing me about $3370/mo right now. Once the escrow adjusts, it should be around $3220. If the mortgage was paid off, it would be around $1000/mo.
When I run numbers like that, I'll admit, it does make paying the mortgage off sound tempting! But, I'm doing fine making the mortgage payment, and thanks to inflation, that ~$2220/mo in principal/interest will become less significant as time goes by.
