Budget for house construction in the Bamberg area

I believe your inheritance (?) is currently burning a hole in your pocket. 250K€ is a lot, a lot of money for someone who otherwise doesn't earn any money. The last thing you should do now is build a house.

The mother of an acquaintance recently died.

My heartfelt condolences.

I am not in favor of financing

What do you mean?

So you have an offer of 300,000 EUR and would prefer to calculate with 400,000 EUR to be on the safe side.
That means you are missing 150,000 EUR for your approach. Now you only want to buy the essentials and move in there so that you don’t exceed 250,000 EUR.

Why don’t you wait until the end of your studies? Why are you against financing? And what is your predicament?

No, no offer, an cost estimate from my architect based on his volume calculation and the standardized cost estimate.

Regarding the rest, I won’t say anything because of the last posts by Tobibi and Bookstar. I think it’s all about attempts to expose [me]. I agree with Tobibi’s assessment of the thread. It’s a pity, some comments like those from rick2018 or guckuck2 sound like things I am willing to consider. Thanks already.

How old are you?

Don't forget, a house costs maintenance! Taxes, insurance, ...

There's a massive troll here!
