I thought with your thread, I understand you very well. Similar thoughts have been troubling us all the time, which is why we have realized even the things that are the most impossible to change (basement).
Ultimately, it will only be about 1000€ net more for us, which my wife will quite certainly, but not completely certainly, have in 1 year. In addition, quite certainly, eventually!!! inheritances of houses in our expensive area will be due.
Then we have not lived for years as we would have wanted, even though it would have been possible without any problems.
Corner windows, smart home, venetian blinds, whirlpool bathtub, higher-quality kitchen and doors... These points occur to us as well (although we earn significantly less ;-) )
So, as I said, I actually totally understand that!
But after I looked at the mentioned thread with 1500sqm land and the mega great spacious floor plans, I find it somewhat strange to still be dissatisfied there ;-)
You surely don't want to trade our 300sqm land and 80sqm buildable area, even if we now had KNX....
