I would like to see the LL land management system incorporate a 'rent' option.
Effectively, as well as the option to sell land, there could be an option to rent it out, with the owner able to choose the rental price and time period. It could incorporate a renewal reminder system. If the owner defaults on their tier, the land would revert to LL in the normal way, but with the sitting tenant now renting from LL. This would be a way of a few extra L$ flowing back to LL as well.
This would be a more reliable system than the current rental system, where tenants have no security.
Effectively, in this system, the owner would be selling their land to the tenant for the chosen period of time, at the end of which it reverts to the owner.
