Evaluation of our financing offer

And why don’t you then also choose 392 euros/month in option 2 (the 270 building saver plus the 122 interest)? After 19 years, this would result in a remaining debt of 50,383 euros instead of the 60,000 in the building savings option.


In your 19 years of building savings from option 1, you pay 27,816 euros in interest for the 120,000 euros.

I have had very, very good experiences with Interhyp. Pay attention to repayment rate changes, special repayment options, and interest-free provision period. I regret today that I can only apply a maximum repayment of 3%. I would have liked to have a bit more, precisely because life circumstances can change (salary increase, etc.).

Hello everyone,

after long disputes with the building authority, we have finally received our building permit, which is why I have now taken another look at the financing.

We would like to invest a total of €300,000 in the modernization / renovation of our house, €100,000 of which we are providing as equity. According to our energy consultant, with the measures we want to carry out, we will achieve a KFW Efficiency House 70. It is therefore clear to us that we want to take advantage of the KfW loan 151,152 for €120,000 (42,000 € repayment subsidy is too good not to do so...). Since we prefer security, it is important for us to know how much we will pay until the end. Monthly, we have targeted about €750.

Our current offer is as follows:

KfW loan €120,000; 10 years interest-only payment €75 / month
simultaneous payment into a building savings contract at Debeka €333 / month; after 10 years allocation of almost €40,000, remaining loan €32,000 (approx. 8.5 years €408 / month); interest rate here 2.21% effective.

Annuity loan €80,000 20 years fixed interest 1.20% effective; €356 / month

The whole thing would then be paid off after 20 years.

What bothers me a bit are the 2.21% for the building savings loan and the fees of €780 for the building savings contract.

What do you think about it?

Comparison offer from Allianz has not yet been received

I consider the fees to be market-standard, but not the interest rates. From my perspective, the [Bausparer der Debeka] currently have the worst interest rates on the market. Take a look at the [Bausparer der LBS] and you'll understand what I mean.

Good morning,

so if you save half or even more of the building savings amount in 10 years, then the nominal interest rate should be between 1.00-1.25%, effectively definitely around 1.50%!

You can look at LBS, personally I don't like them because they often make contracts where you then have to pay a 2% discount on the loan (i.e. here it would be a 1% closing fee of the building savings amount, so with a 75,000€ building savings amount that is 750€, but if you then take out a 32,000€ loan, 2% = 640€ discount on top, so costs (not including interest yet) of a total of 1400€) so rather keep your distance.

if the house and land already belong to you, and the 300,000€ EUR is pure modernization (value-increasing energy-efficient renovation), then the house, when finished, would probably be worth well over 400,000€, right?
then financing 200,000€ = 50%

so you should get the "best conditions" everywhere.

and 1.20% effective for 20 years is also not exactly "the best deal"

So try to make sure the building saver runs with an effective interest rate of around 1.50%.
the 20-year full repayment should rather move towards 1.10% (possibly calculate against it, if you take out 100,000€, you then pay a little more monthly, but if the interest rate moves towards 1%, the 20,000€ more is basically for free... maybe you can still find something you want to buy???

PS. some banks currently also have discounts for KfW, i.e. instead of paying 0.75% for the KfW-151 you then only pay 0.50%, so you can save a bit too ;)

Great, thanks for the tips! I think I'll get in touch with Interhyp again regarding offers.
