Change home savings contract now?

Hello,

Maybe someone here can tell me if I can change an old building savings contract that is eligible for allocation but from 1995 or older with an interest rate of about 5%.
Change this into a building savings contract or [Wohnriester] that has the current interest rates and with a higher loan AND cash immediately.
Whoever understood what I mean, the question is.

Is that possible or not???

I think it depends on the provider. So just ask if such a tariff change is possible. I think that should only work within the provider because you can only get a loan for an already active [Bausparer].

So just ask if such a tariff change is possible.

Tacho,
well, I already called there. My question was answered with a long thoughtful "Yessssss" and the addition that they will surely find something suitable for me.
So I know what suits me and I think I asked my questions in a way that they could have answered with a concrete YES or NO.
Always these sales-commission-sharks.
