Type of use in the land register. Holiday home rentable or not?

You have already received the answer to the question regarding the outer area. If FOREST is recorded in the land register, you are at the middle of nowhere and actually thousands of trees grow there, you can assume that you are indeed in a forest and not in a city with building plots. That sounds like the outer area again, and there no residential buildings are allowed on the property. If there is a hut there, there will be a reason why it is allowed to be there. However, it won't be a normal residential house. And therefore, renting it out should also not be an option – regardless of the fact that you – no matter what kind of bizarre ideas you are pursuing, I at least do not understand your intentions in all the threads – would also have to define a target group that occasionally wants to spend the night in the middle of nowhere.

What exactly drives you? Troll or what are the motives?

How many plots and confusing questions do you actually have?

Not only based on experience but actually visible here, your threads are already all mixed up or confused by page 2.
For you, the concept of a discussion also seems to be new: someone asks, another or several respond right away, upon which the questioner (in this case YOU) asks further questions through explanations and clarifications in the same thread: the discussion builds up and grows.
Anyone who wants to participate can scroll, browse, and read up to provide more information or ask further questions.
This is practically no longer possible with your problem in this forum, since you open a new thread every time.
That won't work.

... but it might be sensible to combine your questions into ONE thread. Then all the information that has already been given is always in one place, so you can refer to it more quickly. And when rereading, you will better understand the connections.

If after explanation you do not understand that it is about gathering information, you might be in the wrong place here.

Dear moderators. I am requesting the deletion of this user. I do not need to be called a troll - in addition to the answers that make me look ridiculous.

I think you don’t understand that you shouldn’t create different questions in one thread because then the title doesn’t match the other questions at all! What kind of logic is that?

One question, one thread. I have run forums myself.
