House construction planning: solid house or prefabricated house? With or without a basement?

Sounds more like to me than "someone" ...

Should not be disrespectful, I just didn't want to read everything again. Sorry :)

I actually know a similarly extraordinary couple like you. They both work for a company that develops computer games. They also sit at home all day and are happy with it. Each as they like.

It just seems a bit strange that someone who achieves so much professionally, enough to manage an 800k house project, doesn't come up with the idea to first look for a plot of land, sketch a floor plan, visit model home parks, or define the financial framework with the bank. On the other hand, your savings rate with your lifestyle is of course gigantic, and the house seems to have a very high priority.

(Re)presentation duties), at the same time you create a "certain" impression through your catastrophic language and writing style that makes me doubt the seriousness of your endeavor.

And as for the representation duty... so what? Since I am aware of it and have one or another deficit, that doesn’t mean I can do nothing...? There are also people who work their way there otherwise and are still not necessarily worse off because of it.

True! But then one can expect some planning and common sense with a focus on the essentials.

And finally, I think salary does not belong in a public forum.

Doesn’t matter? Again the wrong focus. You are anonymous here. I find your flowery descriptions of how strange or not you are much more personal and would hold back a bit in that regard. That is what you present yourself with here – and in summary, that is not a good presentation. Some neutrality with facts belongs in a forum dealing with acquisitions in a high six-figure range. Everything else is unprofessional and tends towards incredibility.
