Financing plan end terrace house

A special repayment is only possible once a year to an extent of, say, 5% of the financing amount. Everything else gets more expensive. If, for example, you receive a variable dividend payout in large corporations, this could then be used as a special repayment. Many plan to include their 13th salary, which, however, does not work out if the 13th monthly salary is also used for other things, e.g. for the children's Christmas presents, the "you-don't-treat-yourself-to-anything-else acquisition," or other things, e.g. the material for the terrace done by yourself, the garden layout, or the new refrigerator, washing machine, etc. The special repayment is not exactly a component of "I'll arrange the financing however I like," but an offer from the bank, and every component costs somewhere. You can see for yourself: the 5% special repayment is already common. But on checking back I see that you intend to do exactly that. I find the interest rate adjustment truly more interesting: if your salary should actually increase, i.e. a permanent raise, then you could go from the small 2,xy% to 6% or so.

Something is off with option 2. Higher interest rates than in option 1 but a lower installment? How does that fit with the identically stated repayment?

Thank you for the comment. There is actually some truth to that. I hadn’t really considered it that way before. With increasing salary, a permanent increase would of course bring much more than a special repayment. I think you can tell that I am basically still at the very beginning and don’t really have much knowledge about many things yet. Everything is moving very quickly with the house right now.

As of now, I really like both the option of special repayment and the change of the repayment amount.

Just also check what further changes to the repayment rate cost. Often these aren't really high at all. A well-known direct bank offers two changes for free, then they cost 100€. So if a windfall occurs, you can adjust well. After 10 years, with a 15-year financing, you have a special termination right. So if an amount is due within this period + the interest rates are attractive, you can conclude a new contract and fully pay in the large amount.

Thanks for the tips. But just asking naively. If I can no longer change the repayment rate for free, I can theoretically implement an increase through a regular special repayment.
