^^Ah, just live in a tent, have almost zero carbon footprint. 
As long as itās a tent with a gas cooktop, two bathrooms and a laundry room. 
Donāt they call that glamping? Iād need to move somewhere much warmer. How much space do you have in your backyard, @HImom? 
Funny! I think weāre all planning on moving in with Himom! But Bunsen is planning on working many more years here, so she canāt move with us. 
Re glamping ā the LA Times recommends, as a holiday gift, that you sign your sweetie up for a four-day camping trip. You stay in pretty basic canvas tents with cots and lanterns. Only $6000 PER PERSON for four nights. Scroll down on the link below.

So camping isnāt solving any budget problems!
Bunsen can airbnb with us for her vacations.
Actually, 2 of my siblings now have airbnb units in/attached to their dwelling and its been a good source of income.
6K for four nights of camping? Yaāll can stay in a tent in my yard for half the price! :O)
Living in an old home now, the next one just has to beā¦perfect.
Personally, Iām not into bugs if I can avoid them on vacation. H and I prefer hotel rooms and restaurants, especially if there are bears and snakes.
Glamping holds no allure for us. Weāve done enough real camping when our kids were young, thanks. Canvas doesnāt protect against temperature swings and Iām too darn sensitive to frigid temps. Yāall can make reservations. Heck for $6000 for 4 days in our yard, I will buy folks brand new Costco tents!
Macadamia nut candies on our pillows?
Itās $6000 for 1/2 a tent for four nights; $12,000 for the whole thing!
But back to BBās question: I noticed no one so far has said at least one fireplace. Would you miss it if it were gone?
I forgot to mention sufficient wall space for art.
City-supplied water and sewer service. I never want to cope with well water or a septic system again. There are enough things to deal with in a house without two extra major systems, both of which cost a bundle if they need replacing.
I second having a laundry room on the main level.
" I never want to cope with well water or a septic system again. "
Ah, but you can be self sufficient with them if need be.
Walk Score 85+
Gas cooking
En suite master bath
Hardwood floors
Open plan kitchen/living area OR huge kitchen island
Strong water pressure
No suburbs
Built before 1965
Basement
Adding a natural gas line and switching out the appliances is relatively easy, as is switching the other direction, from gas to electric.
A lack of gas appliances didnāt deter DW and I from purchasing a home on an island that unfortunately has NO natural gas service. No natural gas; no problem. Weāve installed a dual fuel propane/electric range, propane fireplaces and, most importantly, an outdoor barbecue grill supplied by a direct line from the twin commercially refueled 120 gallon main supply tanks.
Because I donāt like refilling 5 gallon propane tanks. Now thatās non-negotiable!
āStrong water pressureā
Good one. Yes!
Water and power are crucial for me. We installed photovoltaic and have no gas so obviously Iām fine with PV and electric. We also installed hardwood floors, but that was fairly painless since we did it before we moved in. Strong water pressure is good. We are happy in the suburbs.
Attached garage.
More than one bathroom.
Iām pretty easy.
But the first floor master with attached bath. First floor laundry. Open kitchen that I have now is pretty perfect.
When we moved here, we thought we had won the lottery having a 2 car attached garage. Now we would love to build another bay. We are getting soft in our old age
formal dining room
architecturally significant (eye of the beholder idea for sure!)
Iāll give up bathrooms, laundry room, etc for an interesting house, but not the dining room
Attached garage.
Plenty of work space in the kitchen with at least some of it at table height. Thatās hard to find currently.
Minimum of two bathrooms.
Deal breakers:
Microwave over the oven. I have a drawer microwave and it is fantastic.
āHoney houseā - yellow oak wood everywhere
Well water
For my current house, the only requirement was that it was a house in this particular school district. I went from a fully painstakingly remodeled home to the worst fixer upper ever.
Location location location
After 13.5 years, I fully appreciate the location. I like being 15 minutes from work, just out of the downtown core and on a half acre. Weāve remodeled a lot, but we will never fully gut this house or substantially change the layout. We may improve some things - still hate my kitchen with the heat of a thousand suns - but itās liveable.
If we ever move (doubtful) my requirements include a single level ranch. I donāt think those exist in my neighborhood. But I know my house will sell fast. The land is worth a ton of money. The house would be razed.
