Are such price increases insignificant? Can we withdraw from the contract because of price increases if we have agreed in writing since when the prices are no longer the same and we can prove that a construction start before 09/2021 is not realistic?
Why should that be the case? Of course not. You have a contract and the company will adhere to it exactly as agreed. The named price applies for 12 months, then a different one. And again, the
Baubeginn is completely irrelevant. That is why you will hardly find any supporters here for these construction contracts with land service. You bind yourself to a company and deadlines are running even though a plot is not even in sight yet. That is how it is now and cannot be changed, but you will have to live with the consequences. What does the contract say about it if no land is found? Only for the contractual reasons described there would you have a right of withdrawal.
