Ok, then we’ll stick with 15 years. However, the KfW home ownership program has a higher interest rate for the 10 years than the offer from our bank.
good, then KfW doesn’t make sense.
you write offer from the bank. Have you asked a broker? The argument of interest rate security is flawed, no one can guarantee where the interest rate will be in 10 years. 2000-5000 special repayment with that income... ok, you have a high annuity. but that’s just a drop in the bucket. this year we managed 3,500 with 2 kids.
in your place, I would consult a broker, inquire about 15 and 20 years and see what happens, even if it’s just for the good "feeling"
