There is a website that offers land in the area of San Luis Colorado and I do not know of any other place that sells this low:
www.radiusland.com
No closing costs, you can skip one payment if in any trouble. And right now they are having a sale. I just bought some land from them and curiosly enough it was the 11th day at 11 am. San Luis sits on a valley formed in the middle and surrounded by the Rocky Mountains. For me it is a special place because of the area names and the settlers last name which is mine! It was the first town established in Colorado. I know the area well.
They also have land in some other states. As always it is good to purchase land near water.
