And, you sell MORE than your land. You also sell land which is part of a Nature Reserve.
In the medium to long term, that should allow you to ask a premium for your land.
The buyer purchases your land, and along with that the privileges and responsibilities of the nature reserve.
The land and the nature reserve are linked on your title deed.
There is more certainty about what may and may not happen on the land. As with any investment, the greater the certainty, the safer the investment.
