Construction financing without land registry entry

My answer as a real estate banker: No chance without a mortgage, unless you can offer an alternative.

The majority of correct statements have already been made.

Additionally, it should be mentioned that they could also offer you a loan, but it would then cost 4-5% instead of 2% with alternative non-mortgage securities or 6-8% without securities. Provided the rest is 1aaaaaa.

What amount and loan term are you talking about here?

You wrote that you have no pledgeable valuables. Have you also considered a possible life insurance policy? Germans love LIs. This could be an alternative. The LI should have a value that secures the loan after deducting a safety margin of about 20%.

In detail...
Then only whole life insurance and the current surrender value should be greater than the loan by 20%.

Please finance without a land charge. This way you save the costs for the notary and the local court of several hundred euros. However, over the years you will pay several thousand euros more in interest. So please, please omit the land register entry.........
I don't understand why some people always think so short-term. You can still use the land charge later and you will get significantly lower interest rates. Calculate what an interest rate difference of about 4% over 15 years means for a rather small loan (for a house) of 50,000 euros...... Your entry will have paid off quickly.
For large loans, banks generally do not waive land charges or substitute securities anyway....

Notary and registration in the land register are first of all not as expensive as is often assumed and secondly no bank will grant a construction loan without registration in the first rank. The house serves as collateral after all.
