700,000€ house - Are we overextending ourselves?

Our architect hasn't done much calculating yet; we have only had our second meeting. It was more of a "now that I see what you imagine, get used to this amount." Therefore, there are certainly still larger inaccuracies.

Without concrete planning, the cost groups cannot yet be broken down to the next level. This can then take place during the cost calculation in service phase 3. Therefore, you first have a rough estimate based on the square meter or cubic meter prices of locally realized projects and rough cost indices.

Hello,

Hello ,

be completely relaxed. Compared to what we are doing: House + land approx. 800,000 EUR. Equity 300,000 EUR. 500,000 EUR loan. I am self-employed and have the corresponding risk. My wife works in the public sector with a low income. Only I currently earn about 180,000 EUR per year. Long story short: Your situation is significantly more relaxed..

Regards, Steffen
