Is financing a single-family house feasible for us?

We don’t want to disturb the parents on the terrace too often.
It could be that this changes.

Oh, so you took the plot from which your parents [abgezweigt]?

Regarding all the petty talk, I can only say: first world problems. If it becomes problematic to live on 3000€ a month, you are saying goodbye to reality. And not just a little. To the OP: You do have the craftsmen including masons, right? Then definitely insist on having the garage in the building plan including the permit and build the garage at the very end, if there is still money left. Foundations, walls, and ring beams will then be done yourself with the help of friends and acquaintances. That certainly doesn't cost much.

Yes, it is really madness. But I am not surprised that the bank is financing it. The house costs just under 1.2 million. Additional costs, kitchen... are under 100k. At least 300k equity remains. So if something goes wrong, the bank would have to sell the house for 800-900k, which should most likely not be a problem in Munich...

But I wouldn’t do it like that either. However, I think if you inherit a million in the foreseeable future, then you see it differently. The parental houses in the Munich area are logically also worth quite a bit at the moment.

Well, it’s pretty macabre when you have a house worth over 1.3 million and then drive the Fiat into the garage and fly to Turkey for vacation instead of speeding to Nice with the Porsche convertible, but to each their own

Thanks for your contribution!
We pretty much decided that today in the family council.

But the garage will definitely be a good bit smaller. We agreed on 40 sqm instead of 56 sqm.

My cousin will certainly get a week off to help us with the masonry and will bring a friend along. And we also mobilized a few other buddies who can help out with the garage for 1-2 days. The standards aren’t as high as with the house if a wall isn’t 100% straight.

My girlfriend’s parents would also support us financially so that the garage isn’t left out. We hope it works without their help. But it’s good to know that help would be there in an emergency.

However, if already significant unplanned costs arise during the earthworks or the shell construction of the house, then the garage will have to be left out after all.

I can’t understand that €3k after rent wouldn’t be enough.
But since it’s not understood the other way around either—that we manage well and happily with significantly less—it balances out again.

Actually subjective... Our project will also end up over 1 million, probably like almost all new builds here with the land value. But nobody around us currently drives a Porsche. Most are closer to the FIAT. Besides, I don't quite understand what the alternative is. A comparable comfortable terraced house with 170 sqm + basement on 220 sqm plot currently costs about €2400 cold rent and €2800 warm. That’s not enough for the Porsche and Nice with us either. So now you could exchange the basement and one room for the Porsche, okay, whoever wants to. I prefer the basement and a bit more generous rooms.
