Procedure / Sequence of Construction Planning

In this respect, I am not worried that reasonable solutions regarding financing will be found; one has already been described by Dirk, among others.

So we are actually in agreement. I also favor Dirk's solution.

Equity is available, about 20% of the total amount, but if we use it immediately in the building authority to pay off the land, then the money is gone afterwards, so that option is off the table, right?

Yes, you can! The land is also counted as equity. That would also be the easiest solution for you. Then you could calmly deal with the topic of house construction and, when everything is clear, go to the bank.

Optionally, one could also take out the entire or a larger loan and include a clause that 10 or 20 percent are variable and only drawn upon if really needed.

Equity is available, about 20% of the total sum, but if we use it to pay off the land directly in cash, then the money is gone afterwards, so that option is also off the table, right?

Uh, why?

If you can pay the land in cash, you can of course count it as equity when building the house.

Your trusted banker should certainly be able to represent this accordingly.

Including the notary and everything, we are a bit short to pay for the property entirely in cash ... so it doesn't work either ....

Then I would return to my original recommendation.

Use a variable loan for part of the land purchase and repay it again with the final construction financing and integrate it into the "new" financing.

I would also recommend that you do not use all your equity for the land purchase in this constellation. A buffer of equity for unforeseen events is always advisable. You also have to be careful about what the loan is allowed to pay for – some credit institutions vehemently refuse, for example, to include a kitchen or furniture in the financing!

But already the banking issue took almost 2 months in total. That doesn't leave much time until 3 months.

The OP can certainly try, but he should also have Plan B ready so he doesn't have to run around with the banks at the last second.

Yes, 2 months can be about right. But if you have to pay in 3 months, 2 months are enough. You don't even need a development plan then.
For us, there was so much confusion... and we never had any thoughts about building a house beforehand. Then my old loan, which still had 7 years left, I wanted to do a property transfer and I honestly called new phone numbers every day for 5 weeks to find out if it was okay from the bank's side now. In the end, I paid the VFE and we oriented ourselves to a new bank... I can tell you: it works! ...Because the advisors, salespeople, examiners, notary assistants and whoever else can fax, call, email, and make an effort if they know that urgency is required. Because the deal can be lost to them otherwise As Martina already writes above: they don't do all this for the first time. The building will happen later anyway

Then we would go to the developer

Maybe start now to read the posts carefully, that is read the thread again so you don't mix up the terms

Equity is available, about 20% of the total amount, but if we use it directly in ba to pay off the land

Yep, reading into the forum is recommended, and keep a lot of equity reserved for special expenses
