10 or 17 years fixed interest rate on a 250k loan?

Both conditions can be described as "very good" as of today.

How you decide is a matter of personal preference. There are only opinions, no right or wrong.

Personally, I would choose the long term and not make special repayments. Instead, I would invest in a portfolio in parallel and enjoy the low interest rates.

As said: I

I would ask what the shorter one with higher regular repayment, without special repayment and with exactly one installment change (when the property is finished) costs. Then increase the total installment to about 1500€ and take it for only 10 years. After that, almost nothing is left. Alternatively, take the 10-year one and really make special repayments.

I assume that you then take the 10-year fixed interest rate...

I am still a bit torn...

Without special repayments, the longer loan costs about 7k more in the first 10 years With special repayments about 5k.

How did you calculate that? The high numbers just scare me...

Over 170k outstanding debt after 10 years and the uncertainty of how it will continue. Sure... we plan special repayments. However, we do not want to save ourselves to death, especially during the time when the children are still of school age... I always keep in mind that our first financing for the current apartment ran with 4.6% interest (still running for 10 more months). I find the 1.1% for 17 years super in comparison. Of course, compared to the interest rates from 6 months ago, they are high.

The building plot was financed flexibly. After the sale of the apartment, €410k, which we have to bridge finance, will be repaid at once. At the bank I am allowed to repay a maximum of 5%. Or I take a "full repayer", which would be harakiri with 10 years and €250k. I just thought I secure quite cheap interest for 17 years (I know, from today’s point of view they are not so cheap), and stay flexible with the special repayment. Are the 0.74% for 10 years with a residual debt of €171k really that good?…

Compared to most here, your remaining debt is probably quite low. But the loan and the absolute repayment amount are also low. I personally have a problem with "firmly planned special repayments." On the one hand, people say "I always want to repay at least x (special repayments)," and on the other hand, they leave themselves the backdoor open not to do it. You can't just easily get away with a higher repayment.

If the bank does not allow more than 5%, then I would take exactly that, provided it is compatible with the loan for the property. And everything above that as a special repayment. In my opinion, 3% repayment on the loan amount is simply a bit too little, so the remaining debt remains relatively high.

How did you calculate that?

There are various repayment calculators on the internet. The one from Interhyp can also include special repayments.

They all only calculate approximately anyway. I always quickly make an Excel sheet. It's the most accurate.
