Your current salaries are already quite good for people in their late twenties, but unfortunately the equity capital is still really too low for a project of this size. Additional costs and the kitchen must already be covered by the equity capital, and afterwards there still needs to be a reserve left in the account. You will get into your own four walls eventually, but I think it really makes sense right now to proceed step by step, i.e. save a little longer, then buy the right plot of land and then see what house construction is still realistic – especially with regard to family planning. Construction and land prices have simply increased so much in the last 10 years that you can no longer take the financial aspect lightly. However, many people currently have this problem, not just you.
