Mature Mainland Class 5 sim for rent (18,500L a week), can be residential or commercial - no premium account needed

Full Mainland sim (15,000 prims) - 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
It is also for sale (financing is available), however if you rent we will cancel the sale and not sell as long as you are renting
Please IM me or Scott Maroon if you have any questions
