House construction too expensive - Stop building?

The good thing is that you do it in-house. That way you still have good control over the fact that some things that can wait are simply done later.

Please seek professional help. As many have already written, the situation looks really good for you when viewed objectively. If you get caught up in a panic, the encouragement here in the forum won't help you either. Maybe this thought will help you: EVERY homeowner has faced such a point during the construction phase. When I received the first invoice for the earthworks, I also had huge worries that the project would fall apart. Meanwhile, I have been living comfortably and happily in my house for almost 2 years now, and the worries have completely vanished.

There was a similar thread here once with a retraction.... maybe search for that one.

Maybe it helps to know that with only slightly more income, we have significantly more debt overall. My condominium is not paid off, and my plot of land was an additional cost (at nearly 500 EUR/m²). I sleep like a baby. What worries me more is our spending behavior. What I didn’t account for were small purchases like a garden hose, small practical boxes, Red Panda garden figure. And generally stores like Action and Thomas Philips (where you go in with a certain need and come out with ten times as much). But theoretically, that can be quickly cut down.

The good thing is that you are managing it yourselves. That way you still have good control over ensuring that some things, which can wait, are done later.

If panic attacks already occur, self-management is unfortunately anything but good. And moving into an unfinished construction site with the thoughts of everything that is still unfinished and needs to be done does not help either. It would be nice to be able to hand over all the stress, but that is (feeling-wise) not possible for financial reasons. Depending on how bad the racing thoughts are, the fears may fade away on their own as progress is made, or professional help is needed. This cannot be assessed through the forum.

There was a similar thread here once with a withdrawal.... maybe look for that one.

You mean the one from ? I'm not sure if that serves to calm things down. Especially not because another house was bought for a rather wild financing structure.
