Good offer for a young family? Buy yes or no

Very solid and reasonable decision. Without a financial boost from the parents or similar, it would have been really tight. I can understand that well, we also had almost no help and then you just have to stay within your own means. That is better than getting over-indebted. We also live in a small [REH] from 1921, small but mine. That is nothing to be ashamed of (not even for rental apartments of any kind!).

Find it anything but stupid. Even if you had bought it against my advice based on facts, you wouldn’t be stupid, but simply would have made a different decision than I did. It would have been stupid to say yes right away without dealing with the matter. And a big THANK YOU for honestly sharing this decision with us.

That's better than getting into too much debt. We also live in a small [REH] from 1921, small but mine. That's nothing to be ashamed of

There is nothing to add to that.
It doesn't always have to be 150 m² or more.

What is important is that you have thought this through thoroughly once and now have more knowledge about this topic. Ultimately, it is always an individual decision where there often is no general right or wrong. Both would certainly have been possible and you chose to rent. That can't be entirely wrong either, since there are many renters in Germany. One must be satisfied, either way. That counts, and as long as you won't regret it when walking past the house, everything is fine.

I can understand you well. The question is whether the next best property will be more affordable, have fewer flaws, and whether the competition will be limited – after years of viewings, I have my doubts about that. I hope for you that you did everything right and are spared the "If only we had back then..."- feeling.

I also don't think there is a wrong and a right. It may be that you get annoyed as you walk by. But it could just as well be that you have been fighting and calculating for years. You blame your wife for her nails, she says you are not allowed to play computer games anymore. The vacation gets canceled, etc. When it gets too tight, the house doesn't help anymore either. And you are probably pretty close to the limit where it might still be reasonable, but maybe too many restrictions are already necessary. If you are mostly relieved instead of sad, then it was definitely the right decision for you!
