Household income relative to the financing amount

230k remaining debt sounds high now, but in twenty years it probably won't be anymore, I don't see a problem there. If you can no longer finance a house with such an income, when then? Then you would have to generally say, no real estate purchase or only terraced houses. Ultimately, it is a lifestyle choice, but economically your plan is certainly not unreasonable...

I see it the same way, Egberto, especially since new comparable semi-detached houses from the developer in our region start at 750,000 euros + additional purchase costs and usually come with smaller plots of land. I mainly see it as retirement provision.

Loan amount is 470,000 euros.

The whole is financed with a 20-year fixed interest period, monthly installment 1,650 euros, remaining debt approx. 230,000 euros.

I do not know if you mentioned it; your numbers correspond to a nominal interest rate of just under 2.2% p.a. Accordingly, the initial repayment is also about 2.2%. In my opinion, the goal should be a rate where at least 3% p.a. is always repaid. Of course, you can also arrange this with special repayments.

I think your project is ambitious but feasible with appropriate discipline.

We have almost the same numbers for our project. Necessary credit about 460,000 EUR, monthly net about 5,500 EUR, and targeted monthly installment about 1,900 EUR. Only with the difference that both children are already here with us, so we know which fixed costs we have with children (about 700 EUR additional costs that we wouldn’t have without children) and also what income losses result from my wife’s part-time work.

I think it depends a lot on lifestyle. For us, even with the planned monthly installment of 1,900 EUR, about 500 EUR still remain monthly as a buffer. However, we almost never go out to eat (which is usually more stressful with small children anyway) and we also pay more attention to prices in general. You just have to set priorities for what you want to spend your salary on, but in principle, in my eyes, it is doable.
