Buy land - keep the house.. how to proceed best?

A different question about financing the property.

If we could raise a total of 45k now, would it make sense to borrow the remaining 30k at an effective rate of 2.99 for 24 months and in return not have a land charge registered.
The 30k would cost me just under 950 euros in 2 years.

With financing through the Sparkasse, I would have to borrow 55k, the interest rate would be 1.4% for a 2-year fixed rate and 2% for variable.

Do I see it correctly that the former would ultimately be cheaper or am I overlooking something?

So the question doesn't get lost ;)

Cheaper without mortgage.

Now I mentioned this in the consultation at Interhyp as well, and the advisor told me that I could not transfer the construction financing to the new project, that I would have to pay the prepayment penalty and take out a new loan.

That can't be right, can it?

Clear answer: It depends!

However, if the bank agrees that you use the new property as collateral, the financing can also be transferred. That is entirely at the bank's discretion.

Maybe the payoff against VE is also an attractive option?! You have to do the math.

She presented it as if it wouldn't be possible at all. I had once read about transferring it.
