Do you mean you first bought it for xxx LS and then you pay tiers xxx LS or better called "rent " to the seller ?=Estate
We have lived one year now on a homestead sim, very stable group of sims.
Costed nothing to have and we only pay rent for it.
Same amount of prims as you have,no lag and a lot of space.
All waters around these sims are shared so u can sail fly or do whatever around them.
So you dont have to "buy" at all ..Just pay the box and its yours to rent (but you own nothing ...)And choose the sim with care.
