1. Click the Buy Land button.
2. Click on a parcel you own and set a price in Atlas Bucks. The minimum price for a parcel up for resale is 150 AB. 
3. Click 'Confirm' to confirm sale price.  When a player buys your parcel, the Atlas Bucks will be added to your account after the purchase is completed. Atlas Earth keeps a 20% sales fee for secondary parcel sales. Your land will continue to accrue virtual rent for you until it sells.

If you put land up for sale and then change your mind about selling it, you can cancel the sale at any time, as long as another player hasn't bought the parcel(s) yet. To do so, you will have to go to where the parcel is located and click on it.
