When building a house, you lose feathers. Many feathers. And mostly only because you depend on others. The biggest frustration is "lost money," which you record for yourself due to time delays. Others are held accountable. Of course, you can try to sue everyone and everything because you believe you are right. However, you also have to make sure not to use up your strength and energy right at the beginning. Building a house will still be exhausting, also in terms of finances. A few days ago, this was about [Bereitstellungszinsen], which you wouldn’t have without building a house. The classic is the delayed start of construction, mostly somehow hidden in the fault of the builder (e.g., due to changes). Or terminating the apartment lease too early because you cannot imagine that the interior work can cause problems. Just recently here in a thread, the information was given that the screed is not drying as expected. There are no accusations of guilt there either. Maybe there is a reason why you can only upload once on the [portal]? Maybe you should/must have pointed out changes to the construction plans? Without knowledge of changes, I probably wouldn’t take another look either. Maybe you were too optimistic with the building savings contract because of the allocation or Maybe you should have simply checked everything yourself again for consistency before the forms were provided multiple times and unsorted. Maybe the advisor just screwed up by no longer checking your faulty documents?! But did he act deliberately or through gross negligence? One thing is certain: if interest rates had dropped, he definitely wouldn’t have heard a thank you from you for his clumsiness. My advice: save your strength. You already have a small list of experiences behind you at your desk. But; it will get even more adventurous when the trades have to work together.
