Question about my construction financing

Hello,

I am planning the following:

- The plot is reserved and should be purchased next month. Cost 58,000 without realtor, fully developed, so including notary and land transfer tax approx. 61,000 euros.
- House construction next year in April approx. 260,000 euros.

What I have:
- By next year February 90,000 in liquid equity.
- Home savings contract 100,000 with approx. 3% loan interest, currently 24,000 paid in.
- Parents' home savings contract 25,000, currently 7,700 paid in.
- Kfw 70 50,000.

The 25,000 one could become eligible for allocation in December 2014 after consultation with the building society by a one-time payment of 12,500 (has been lying there for a long time). Loan interest 3.15.

So now there are several possibilities to reach the total amount of 320,000 for house and land;

1. Earlier use of parents' home savings contract:
This means taking out less money, i.e. instead of borrowing 230k including Kfw, only 205,000 would need to be borrowed.
But then there would be KfW, building society, and bank as lenders, are there problems with the land register regarding the lending bank? Or higher interest rates?

2. Borrowing the full 230,000 including KfW and then repaying later with the home savings contracts.

3. Like 2 but the home savings contracts replace the bank loan after the credit period expires, but then the money is basically just with the building society for 10 or 15 years with hardly any interest.

4. Solution 1 from 1-3 but the home savings contract 100,000 is already being used now by reducing the contract to 60,000 and having it paid out next year, thus financing less initially. For that, nothing to repay the bank loan at the end.

Do you need any more information?
What do you think?
Thanks in advance...
Sorry I know I may be asking too much here because of many parameters.

Best regards
Thorsten

Hm just saw in the interest calculator that with a 230,000 loan I have to pay exactly the same rate as with a loan of 205,000 plus the rate for the 25,000 [Bausparer]. Namely 908 euros with 2% repayment and the remaining debt is similar with 15 years interest fixed, hmm

Just as a thought: I got 3% on 100% full financing over 15 years. You don’t need a [Bausparvertrag] for that nowadays...

Hello soroka, yes the thing is now the building savers are already there and saved up to a certain extent. It probably makes sense to keep the BVS for the later repayment of loans. Keyword interest rate security. In the meantime, the balance just sits there relatively worthless at 1% interest on the balance.

And where do you think interest rates are heading in the near future? Just keep the [Bausparvertrag] and take a regular loan now... But you get better interest rates on any [Tagesgeldkonto]... (but this is just my unprofessional opinion, I'm not a banker)

I see it similarly, but in 15 years the interest rates could be higher again. That’s what I mean regarding where the interest rates are heading;-)
