Can relate. After moving around a lot we bought our "forever home" 10 years ago. Forever doesn't last that long. A big house owns you. We're trying to sell.
So looking out from that position, people interested in another 1000sqft are usually thinking of hobbies, exercise equipment, shop space, media room, etc.
What about the big house is owning you? Mortgage and maintenance?
But it’s just the feeling of freedom that I like about it. My wife can cook things without us worrying about the mess. I can spend my free time as actual free time, instead of worrying about household chores.
That’s nothing in any higher cost of living city, which is where most high income people want to be. That kind of labor will probably easily run you $200/day or more.
