Buying a completed new building - Will the warranty be maintained?

I mean, then you get a "Finanzierungsbestätigung" from Sparkasse (it's not a contract, just a preliminary check to see if financing would be possible), go with it to the seller and to the notary appointment. Then, with the notary documents, you go to xyz-Bank and arrange the financing there. At this point, the seller can't back out anymore. No idea if that could work like that.

The trick doesn't sound bad - the financing tangle itself can hardly be secured by the Sparkasse in the land register ;-)

As a rule, however, the conclusion of the financing will be a prerequisite for the notarized contract. With some skill and timing, it can be managed within the 14-day right of withdrawal.

Or you conclude the financing contract and then withdraw within 14 days. Although, we recently had a similar case here in the forum where for some reason it was not possible.
