well, the thing with the provision interest is already "bitter". But one question: You acquired the plot + (unfinished) house together from Okal Haus? That they then want to know from YOU how to reach the plot with a truck, etc. is absurd, isn’t it??!!
Was the financial broker also brokered to you through Okal Haus or did you look for financing yourself?
A lawyer would certainly not be wrong, to check if everything is so "legitimate". But that again takes (in the truest sense) precious time.
Developed: road, electricity, water, sewer. For planning line routing of supply and drainage. Maybe that doesn’t fit into their concept of integrating you into the "corporate process flow" if there are these "unknowns."
: We inquired with several providers about a prefabricated house and ultimately decided in accordance with price/performance offer for Okal Haus. The sales consultant from Okal Haus mediated a plot to us, which we had to buy from an external company.
A lawyer would currently cost us about 250-300 euros hourly rate and a lot of time, which we do not want to spend at the moment. I will first try to clarify the open questions myself.
The plot is currently not developed, as it is a new development area. An application for development has already been submitted by the plot seller, but was rejected by the building authority with the reasoning that a building application must be filed before development can be carried out.
Okal Haus, however, refuses to file a building application and demands that the plot must be developed before the building application is submitted. (Chicken-egg problem)
What interest should Okal Haus have in stalling a customer? They make their money from building the houses and not from preventing it.
Here seems to be the crux of the matter. You are stuck between the authority and the service provider, both demanding that the other one takes the first step. Pragmatically, you resolve this situation - possibly with help. Whether that needs to be a lawyer is debatable.
: Okal Haus makes even more money if the period of the Okal Haus price guarantee of 15 months has expired.
Regarding the latter, I agree with you, which is why I am trying to clarify the questions from Okal Haus somehow. A lawyer would currently only cost me unnecessary money.
Many greetings,
