Is financing possible with ING?

The only thing I find strange here, despite many useful hints, is why every second thread opener is accused of being incapable of calculating on their own together with the trusted construction partner?!

my husband is provided with both the craftsmen and the materials.

He can also invest 2-3 months of his own time on the construction site (agreed with the client). Then it won’t be possible to take a vacation, which doesn’t seem likely anyway at the moment.

Monthly payment €970

Because the bank might have similar considerations?
For the reasons mentioned, I would find it difficult to get a loan for you.
If unexpectedly 50k additional costs come up, then it will be difficult.

Why did the financial advisors advise against it and why is there a higher interest rate?
For us, it was no problem at all to buy the plot beforehand. We financed it variably and had great interest rates recently. Meanwhile, we have paid it off with the house loan. This situation happens quite often.

I don't understand how a monthly rate of €970 + €500 additional costs (which will actually come up in 1-1.5 years when the house is built and we have moved in, and after my husband has potentially increased his net salary by another €200-300) can ruin our lives so much

The reason was that in this case bank no. 1 is registered in the land charge, which makes financing pointless for all other banks.

Couldn't that also mean that something might not be right with your planning after all? What does "provided" mean, free of charge? €48,000 of own labor at, let's say, an average craftsman wage of €40 means 1,200 hours of work. In 2-3 months' time, that would be 20 to 13.3 hours per day, 7 days a week. And I don't think your husband is as fast as craftsmen who do this daily. So either you have a very good breakdown of how this €48,000 adds up, including additional material costs, etc., or the bank should reject it. Sounds surprisingly little as well. Would you like to mention the loan amount, interest, and repayment rate?

Well, all that remains is to wait and see what comes from the bank. However, we did not just think the financing concept through in our heads, but planned it thoroughly together with the financier and the developer in two meetings and with a solid buffer ‍♀

If a rejection comes from the bank, I would definitely try to push through the option with the land. Otherwise, it probably will no longer be possible to build there. The reason was that in that case Bank no. 1 is registered in the land charge, which makes financing pointless for all other banks. And then we are bound to this one bank, so they can set the interest rates higher. Roughly, as I understood it. But we can definitely look into this option more closely again, thanks for the tip.
