[Buying land for a group...]

You should only have an alt as a co owner of a group that has deeded land. It doesnt matter if they are your partner, bbf, whatever. They could sell the lsnd to themselves if they wanted to, and you would lose everything.

Actually, they wouldn't be able to if they are not a premium member, you have to be a premium member to be able to buy land in the first place. 
If that were the case, then everyone would be creating groups just to be able to buy land.

My question is this.
If you set someone as an owner in your group.
The group has the land already donated to said group.
Can the assigned group owner, be able to buy the land and deed it to the group, if that person themselves is not a premium member?

Ok I think I understand now
So may as well wait until my billing cycle to upgrade then proceed with doing the rest.
Thank you both for the fast answers.

[upgrading tier]

Right, I understand all of that
Here is my question
I currently am paying for 1/8 region
I want to upgrade to 1/4 or 1/2 region
My billing cycle is on the 5th
If I upgrade now, abandon my current land, get a new parcel after. 
Would I be charged the additional land tier now, or will it reflect the change and charge me on the 5th?

[upgrading tier]

If i want to upgrade my land tier, does it charge me automatically the moment I do it, or does it charge me at my next billing cycle?
I would rather my billing cycle not change, and if need be can wait until my billing cycle to upgrade. It does make it difficult in manner of being able to get land on say actions that run out before my billing cycle date.
