A Full sim on Mature Mainland - no covenant, so you can do what you want.
If you rent then there is NO up front money - after all you are renting so why pay anything other than the weekly rent of 19500L.
It also for sale, however if you rent I will cancel the sale and not sell it as long as you are renting.
I also have a 1/2 100% flat green sim available:
