It’s of course somehow tempting not to have to rely on chance/luck.
Is it nobler in the mind ... (Shakespeare already asked). I would rather "try" my luck than prefer a "safe" getting imposed on me. But everyone is allowed to be young and fearless once, so don’t force yourself otherwise for my sake.
New development area (framework plan not yet decided, let alone the development plan) with several single-family house plots. The marketer (not the city) said they cooperate with a developer, called them. They say yes, we have exclusive plots reserved in one sub-area – and the list is already 50% full. If you sign a purchase contract now, you also get on this exclusive list.
What do you mean by a “framework plan” – an urban development concept? – the development plan can still take a while. That sounds very likely to me like a "project-related development plan" that the land developer will prepare. I suppose we are dealing here with a larger brownfield that someone has completely acquired. And presumably, the municipality has signaled its goodwill on the condition that a part of the building plots must be put on the open market.
The plot is not sold by the developer, though. I’m waiting for the documents. There shall presumably be a right of withdrawal if you are not satisfied with the remaining plots.
To me, your description sounds like developer-driven – however disguised (the marketing sister company has a different name than the construction company), fiscally I see you paying tax on both the cake and the icing. I’d be happy to look at the documents non-bindingly – you “are allowed” not to send a PM yet, but at gmx (de) I have the same member name
