Experience / Opinion on home financing with a high loan amount

2.5% is a tight repayment. The OP even wants to reduce it. Most banks want at least 2% to be repaid. At 2.5% you have a very large remaining debt to extend. Since my crystal ball is broken, I cannot say what the market interest rate will be then.

Dear HilfeHilfe, it would be very helpful if one took the trouble to read and understand the OP’s posts completely, and if something is not understood, better to ask first before starting or igniting further unnecessary discussions.

Evaluations, assessments, and advice should be based, in the interest of all, not on assumptions or misunderstandings, but on the facts the OP provides or inquires about.

This greatly helps the structure and order of the threads and makes communication more pleasant and more helpful and effective for the OP.

We have now received a financing offer with an interest rate of 0.8% for the KfW (fixed interest period 10 years) and 1.53% (fixed interest period 15 years) from a savings bank, the monthly loan amount would be approximately €1650 with a repayment rate of 2.5%.

OK, therefore the advice is simply to visit another bank or intermediary. Intzerhyp or Dr. Klein. A 2 repayment rate change that is free of charge is market standard. Unfortunately not with the savings bank.

The two providers you mentioned have each recommended the savings bank to us. A big advantage with the savings bank is the fact that we would have 24 months to use the loan (12 months would be very tight for us).

The two providers you mentioned each recommended the Sparkasse to us. A big advantage of the Sparkasse is the fact that we would have 24 months to use the loan (12 is very tight for us).

Are you building for more than 12 months, or is completion scheduled after the 12 months?

Are you building longer than 12 months, or is the completion scheduled after the 12 months?

Yes! Including the development of the plot, etc., we are expecting a realistic construction period of 16 - 18 months.

Is that the Berliner Sparkasse?
