How much for repayment and loan?

Just as a counter calculation: We have a net income, as the sole earner, of 3500, soon 4500, and repay with 1000, calculate 500 additional costs and special repayments from the second income up to 7000 annually extra. (3 soon 4 people in the household, 340k loan)

, you are actually at an advantage or an exception as I would suspect, since normally if more children follow, due to additional parental allowance and higher expenses, it generally becomes less. Unless you are in the fortunate position that one partner earns that much alone. Then of course it's a different matter. ;)

Hello everyone,

First of all, thank you for your answers.

Whether a company closes can never be said with certainty. The company is a corporation and IG Metall.
Employment longer than 10 years.
Children, recently 2. The first is already 2 years old.
The 1750€ was saved with an income.
Currently no rent costs. :-)
The wife, as planned, wants to work part-time again in 2 years. Since the children will then need more €€€ for XYZ, the "surplus" from the part-time salary could flow into special repayments annually.

The plan is a 1000€ installment, but are 450€ for ongoing additional costs for a single-family house sufficient?
