Which financing option, TH or building savings contract?

Hello,
I received three options from the advisor here: [Tilgungshypothek], [Bausparvertrag], and [Bausparvertrag mit Sondertilgung]. Can one say which of them is better/worse? I tend more towards [TH] or [Bausparvertrag], because with the [Bausparvertrag mit Sondertilgung] the special repayment is contractually fixed. With the [TH], it would be voluntary whether you pay it in, and I would also pay it, but you are flexible and if you currently have other expenses, you can omit or reduce the special repayment. I am uncertain about the normal [Bausparvertrag] - the advantage of both [Bausparvertrag]s is the long interest rate security.

Our advisor says a building savings contract only benefits the bank. Since with the same fixed rate significantly less interest is paid at the end with the annuity loan, this also applies here. So no question: number 1 would be it from my point of view.

You are comparing apples to oranges. Calculate how the financing develops until the end.

In option 1, it ends after 15 years. With the BVS, the calculation ends with the end of the financing after 25 years.

10 years is a very long time and the residual debt without prior special repayment is still a substantial amount.

How likely is the special repayment in option 1?

: I love such statements. Just compare the typical TA/BVS with 30-year annuity loans.

Everything else is saving costs versus security.

I am aware of the comparison apples to oranges. I just don't know whether variant 2 and 3 are good, average, or rather bad offers and whether it is worth preferring V2 over V1?

In V2, the financing ends after about 30 years. In V3, it ends after 25 years.

The special repayment in variant 1 is actually firmly planned for the next 4 years; most likely, I would even increase it to 7-8000 annually in 4 years.

: you really have to do the math on this.

Assuming you completely leave out the special repayment in option 1 to make it comparable with option 2. Then the follow-up interest after 15 years only needs to be 3.1% and you have caught up with option 2.

3 is good. 2 is rather normal

So if you can repay such a high amount, then for me it would definitely be no question. Version 1. Then after 15 years less than 100k remains. Interest rate increases or not. Your loan-to-value will then be excellent, so you will get good conditions. Just enter the future conditions with various possible interest rates and also compare the possible follow-up financings. If you can live with the lower security of V1 and sleep well, I would recommend it to you. If you have concerns about it, then choose the safer but more expensive building savings contract variant.
