You can only relinquish lands in which case you lose the investment on both the house deed and what you paid for the land itself. The second person then can only purchase the land again but it would be at the most expensive price possible as it resets the depreciation timer. They also will have to purchase a new house deed.

So in order to do this your FC will have to come up with the funds of both plus extra for compensation to you if you are expecting that.
