Is a combined building savings loan sensible?

Unfortunately, we cannot invest any more equity. 30,000 is what is currently available. Another 15,000 is still tied up until the end of the year and unfortunately will only be available then. We had also considered topping up the equity with a small loan. So we split the loan amount and take out a loan of 370,000 and one of 30,000€. What do you think about something like that?

Oh, we like to take a bit of risk. We calculated it once. The interest rate for a 15-year fixed rate would only pay off if we had to pay an interest rate higher than 8% for the follow-up financing of the 10-year option (considering special repayments). We would be betting that the interest rate stays lower. The remaining debt after 10 years would be €130,000.

Many banks only offer construction loans starting from 50k, a 30k loan would then be a "regular loan" with worse conditions. And then there's the Schufa issue. I wouldn't do it. Can't part of the expenses wait?

The interest rate for a 15-year fixed interest period would only be worthwhile if we had to pay an interest rate higher than 8% for the follow-up financing of the 10-year option (considering special repayments).

You calculated that well! But I can only advise you to get more offers. I find your interest rate for a 10-year one quite high. What are the initial total payments (loan + bs)? Especially when planning a family, I find these combo offers rather meh. They are more worthwhile for people who are 20 years away from retirement and have already gotten through the "worst."

The problem is that we now have to prove the equity to the bank and then we have to use it first, in September. Therefore, only what we currently have can unfortunately be used as equity. We have already discussed this in detail with our advisor.

The total monthly burden with [Bausparen] would be €2,300.

I then calculated the same for a pure loan and the total costs would be lower than the option with [Bausparen].

That doesn't really seem attractive to me anymore.

I have now scheduled two more appointments with banks.

a 30k loan would then be a "normal loan" with worse conditions. And then there's the Schufa thing. I wouldn't do it.

A small part with worse conditions can be worthwhile if the larger part has better conditions.

And this is simply a calculation of options and an overview of total costs.

Another option for better conditions under 30k would be a building savings loan as an unsecured loan.

Both can quite well leverage the "equity ratio."

And the Schufa in both cases doesn't matter because you commission the whole thing in one go.
