So for us, it took about 1.5 months from the first contact with the municipality until the application was sent. Our caseworker was very motivated and we had several phone calls (nothing in person thanks to Corona). It took a while because of the proof required for my wife. She was on parental leave, but it was over at the time of the payment. It was about calculating the income, which actually refers to the previous year. Then the second hurdle was the bank that finances the rest. Both banks wanted confirmation from the other bank before making a proper offer or accepting the application. But that was also resolved after some emails and a lot of waiting time. The [hessendarlehen] doesn’t seem to be very well known. I even had to explain it to my financial advisor :rolleyes: I should have done it completely without him. He was absolutely no help for the loan. The application was processed after 3 weeks, and then there were some questions from the [Wibank]. Unfortunately, the caseworker there was not very friendly. Since I read the documents very carefully and some points were not clear to me, I asked questions quite often. She didn’t seem to like that very much. In the end (6 weeks after receiving the application, the approval came) it worked out. Based on your question about repayment, I can only recommend that you read all the documents very carefully again. You can repay as much as you want at any time and completely without a prepayment penalty. I don’t know if you can do that through the installment, but an extra payment works fine too. Generally, it makes more sense interest-wise to feed the other loan with the extra payments. I would just stick with the 20 years for now.
