What constitutes a top of the line house in Eastern Europe? It's unlikely to be what Mississippians consider top of the line.
Keep being smug, it just proves my point, Americans still think Arabs live in tents in the desert, Chinese live in the jungle and eastern European build houses out of cow dung and straw. Enjoy your 1m+ stick and cardboard mcmansion that won't last two generations
Even in Mississippi what you describe would not qualify as a "top of the line house". In fact that would be pretty average working class home.
The kind of homes a lawyer or doctor could afford to buy in low cost area like mississippi can easily be 2 or 3x that size and resemble small castles. Think elevators and wrap around double staircases.
Oh and I forgot, it passes passivhaus requirements
I wasn't trying to be smug, sorry it came across that way.
Some of these models are pretty modestly priced (~$500k USD) but more modern than any house you'll find in North America until you reach a price point in the several million range. Certainly higher quality, nicer and more modern than any McMansion.

This is largely lakefront property in a somewhat touristy area of my state, so that influences the prices a lot.
Your link is just expensive homes on real estate with varying levels of build quality by the look of things so not exactly comparing apples to apples...

P.S. I'm not trying to prove anything, I just thought it'd be interesting to compare. I think my original comment about top of the line houses in Eastern Europe came across as combative/challenging when I didn't mean it to.
Anyhow it's a funny place. My wife's 92 year old grandma had to be forced to add heating and an indoor toilet to her 100+ year old farmhouse (old people are stubborn) meanwhile, her cousin in the same village has a modern home with solar panels and every convenience you can think of (including AC).
