I have a 3000sf House, Nice thing about it is it has a Casita, I have been using as an office for my side business for awhile. Now my wife using it since she is working from home and will probably continue to do so.
We have no need for the 5 bedrooms and 3 1/2 baths, but we love our backyard, nice play pool, fire pit and lots of room to entertain. We have been talking about selling it, we have enough equity to purchase a smaller home outright, but would have to give up the backyard. It is hard to find smaller homes with big lots in the Phoenix area. Particularly since we want to stay near my work. (I am only 4 miles from my plant).
I figure I am probably 7 years from retirement, since my wife won't retire until then. Though there are days when I think I will just go ahead and do it. So we will probably wait to sell the house, but then again we could invest our current house payment until retirement. But I love my backyard. If you climbed my wall in the summer, you will find me floating in my pool with a beer in my hand with classic rock playing, probably not wearing a swim suit.
As to keeping the house clean that is what a cleaning service is for, we have used the same lady for over 10 years. I don't work in the yard, so we have a landscaping company. Other than we can't go out and listen and dance to live music right now our life is pretty easy. We have been spending more time on the golf course this year since we can do that. Still a terrible golfer, but a good excuse to drink beer (like I need one) and just enjoy the Phoenix weather.
