Find acreage and land for sale by owners by looking on land sale sites such as LoopNet.com and LandWatch.com. Other sites you can use to find land and other property for sale by owner include Zillow.com, ForSaleByOwner.com and Craigslist.org.
LoopNet.com contains several tools that allow you to locate land in different amounts of acreage for sale by owner, including the ability to only view listings zoned for specific uses, price range of the land, tax rates and the price of the land per acre. Individual listings contain in-person pictures of the land along with satellite images to give you a sense for the overall size and scope of the land. If you are interested in purchasing land found on the site, contact the owner directly to make the appropriate arrangements.
Listings for land found on Craigslist.org can also be sorted by factors such as price range and size, though due to the more general nature of the classified site, more detailed filters are not available, as of March 2015. As Craigslist doesn't set any minimum guidelines for what is required in posts made on its site, the quality and amount of information in each listing varies from poster to poster.
