There does not have to be a causal connection between "owner-occupied" and "no resale within the first 10 years." You said that it is about the topic "owner-occupied." The question now is how this is formulated in the municipality's sales contract. And you can surely also provide your possible input on that. I can quite understand the municipality's approach: It is about preventing speculation with "cheap" (which is relative…) acquired plots of land: The sale is to be made to the "end consumers." In many municipalities, there is a sophisticated point system that practically makes it impossible for outsiders to get a plot of land. In addition, there is usually a building obligation (to prevent hoarding of building land). If a building is not constructed within the specified period (alternatively: ready for occupancy; construction started, etc.), the municipality has a repurchase right. I don't find that so bad. Due to the building obligation, it is usually ensured that a building plot is fully developed within a manageable time frame (when the sale of building plots is ongoing). To be honest, I would not worry about it if resale is not contractually excluded: If the new buyer also "lives there himself," the requirement is still met.
