I might be harshly criticized for this post, but I still want to briefly add my two cents.
We signed in June 2017, construction started in October, and we moved in July 2018. We built about 40 km east of Dortmund. According to the contract, our house cost 216,000 euros, and a 6x3m prefabricated garage was included.
Our salary situation was very similar to yours, we just didn’t even have a third of your equity. If I had inquired about this project here back then, I probably would have been massively scared and intimidated. Whether the construction would have ever happened – rather doubtful.
I just want to say that these inquiries here make sense, but often only the worst case is considered. As I said, sensible, but sometimes also a bit disturbing.
For example, our garage was calculated at 6,000 euros, and that already included an outlet as well as an interior and exterior lighting point. The foundation too. When I read here that a garage costs 15,000 euros and then you have to calculate a few thousand more for the electricity, I wonder what kind of luxurious garage that is supposed to be.
Our plot was quite cheap at 50,000 euros, so in the end we only took out 310,000 euros and even had a few thousand left over at the end. I realize that maybe we are not the rule, but it doesn’t always look as bleak as one might get the impression here. (We also had some problems, you can read about them here, but these only cost us nerves and time.)
I don’t want to attack anyone posting here, just shed some light where there is a lot of shadow.
Regards
P.S.: Of course, I want to join the previous posters regarding the land. At least for us, that was harder to find than someone who builds a house on it. So first find the right land.
