What interest rate is realistic?

Hello everyone, here is my first post and right away a question:

We are currently planning our construction project for a solid house near Koblenz.
The total costs including additional costs and land amount to €560,000.
We have €360,000 equity that we want to invest in the house.
So we need €200,000 external financing.

With an equity ratio of about 65%, in my opinion, we should be offered the best interest rates since the risk for the bank is virtually zero.

The €200,000 should be repaid with an annuity loan with a fixed interest rate for 10 years within 20 years, so a rate of about €1,000 per month.

To simplify the income situation, we will simply leave my wife out of the calculation.
My income is currently €3,200 net per month with 14 monthly salaries.

A monthly payment of €1,000 should therefore not be a problem.

We have no skeletons in the closet or other debts that could have a negative impact.

My house bank made me an offer which I actually consider outrageous:
an interest rate of 2.4%.

What do you think is a reasonable interest rate considering the current interest situation?

Is the house to be built going to be owner-occupied or is it a rental property? Should it be a single-family house, a two-family house, or a multi-family house? In any case, one would probably be in the range below 60% BW, maybe even 50% BW, with normal assumptions. If it is exclusively a single-family house for owner-occupation, you should end up at about 1.90% p.a. For rental, 2.40% p.a. is not entirely unrealistic.

Hello,
have you already used the calculator on the Interhyp website? There - when entering standard data, which of course are not known here as such, like type of construction, etc. - interest rates below 2% come out (I just had one of 1.81%, installment 967 euros, initial repayment 4%). I would definitely get some online offers and an offer from an independent financial advisor.
Best regards!

Hello, the house is a single-family home that is used exclusively by its owner. The loan-to-value ratio is 35%, I had written that incorrectly before.

Yes, with the online calculators it's always a bit tricky, as they always state from x %. I am looking for a realistic assessment, not possible promotional offers with conditions that 99% cannot be met.

I stick to the above statement that the condition will apply for <60% BW or <50% BW.

Furthermore, I doubt that Grundstück+Baukosten+Nebenkosten=BW.

Roughly, you can first deduct 10% flat for ancillary costs. And then another 10-20% from the remainder as a safety margin. Even then, you would still be just under 50% BW.

You won’t find better offers (with less BW), as no bank offers that (cost/benefit/effort).

Currently, a regional bank here would offer about 1.89% p.a. eff. as the valid rate. But a week ago, they were still happy to charge another 10BP more.
