Land auctions can be a source of cheap land for sale. Found in local newspapers, the land for sale through auction is often the result of bankruptcy so a quick sale is needed. It can be easy to become carried away at the auction and pay over the odds for the land. It is recommended that the first time buyer attend an auction prior to purchasing to observe the process before parting with money.
Land auctions are not without risk and often operate very much on a sold as seen basis. It will be down to you to ensure the land is suitable for its intended purpose and to have any inspections carried out prior to the sale.
