Housing Help

Hi I was curious has anyone relinquished their land to purchase a bigger lot? When FF14 first came out with house 3 of us purchased a small lot for our free company. Especially sense it was only made available at the time for free companies only. Our free company has grown and we have more members. We all pitched in to buy a bigger lot for our free company. However when you go to buy the land it tells you that you are unable to obtain any more deeds. So if we relinquish the land our company should be able to buy a new deed right? Or is it bound and only allowed to buy one deed once forever that you have the same free company. So then if you relinquish are we unable to attain land ever again?
Appreciate any help.
Thanks

My FC upgraded to a bigger plot too.
You have to relinquish your land before you can buy another.

Awsome Thanks for the help and reply :)
