House financially feasible at about 5,000 net?

PS:

M2 price is about 5,500 Euro/m2
Currently selling for 8(!). If the house is worth 4,400 Euro/m2 in 5 years, you may quote me and I will personally eat a broom in front of you!!!!

Those who pay particularly high prices have a high potential to fall. As a stock market professional, you should be well familiar with the concepts of Growth and Value. Also, you surely know that particularly highly valued tangible assets react most strongly to rising interest rates by depreciating.

And your numbers do not quite add up. First, you wonder how much your developer earns, now you tell us how far below market the new build would be. That does not fit together. No developer lets the chance pass to pocket the difference if the market allows it.

But you do know that the house will not be in Buxtehude, right?

Prices have also doubled in Buxtehude in recent years. And the farmers and shipowners there probably have more emergency cash than the IG Metall workers with expensive tin in front of their huts.. ;)

But in this particular case, there is no equity portion ;)
I also wouldn't assume that the bank will let forced auctions happen because of a general downturn and realize losses. You can't just easily get the missing remainder from someone who just lost their house.

And a problem could arise if regulations are changed accordingly and the bank has to take a closer look

The 30% price drop potential comes from Bundesbank studies, and applied especially to the "boom centers," but also to the wider area. And at the same time, the new regulation is now coming that banks must buffer significantly more precious equity for home loans. Preventively, of course. How banks will react in a crisis is hard to say. It's all from a while ago - like with the last pandemic. Only one thing is certain - the state's coffers are pretty empty, and something will move in the banks' books that can definitely lead to action.. ;)

143m2, price 790k minus the KfW subsidy All apartments/houses currently listed are just under 8k That's how it is... But I don't really care. I am secured family-wise, rent would cost about the same, so building is the better option

Exactly. In a pinch, you just pawn Mom and Dad because you messed up! No stress.

But it doesn't really bother me. I'm secured family-wise, rent would cost about the same, so building is the better option

Maybe you'll notice it yourself eventually, if not: the somewhat subtle and also provocative comments from the other discussants are mainly because you come across as only semi-likeable with the combination of your history and your "new way of presenting yourself"... it feels like a mix of the old, overly anxious hausKauf1987 and the new hausKauf1987, brimming with self-confidence and arrogance, would be a pleasant and normal person... maybe you'll find the right balance yet, one can only hope ;)

Funny. Here with us in Konstanz, old apartments are around 5000€/sqm, new apartments start at 7000€. Nobody really talks about houses here anymore. Since I find that way too expensive, we're moving away. The Stuttgart area is similarly expensive, so I find it strange that you should be so much cheaper. Sounds to me like comparing apples and oranges.
