I have a brokerage in Indiana, Kentucky, and Tennessee that focuses specifically in land, so what I have done is created a nationwide advertising service to attract more buyers. I advertise on several investor channels like CNBC, Bloomberg, Fox Business and then also channels watched by people interested in land and the outdoors like the Outdoor Channel.
Other options to consider are selling your land with owner financing which makes it easier for people to afford. Trying to find cash buyers can be difficult depending on your asking price and banks don't typically want to lend on vacant land. Also, if you have land you want to sell in a hurry and you'd like to get cash for it there are a number of wholesale land buyers that make be interested in making you a cash offer for your land.
If you need to find a buyer fast, our company is in the land buying business. If you've got time to wait for a few months, then get it posted on your standard online sites (don't underestimate Craigslist!) and consider hiring an agent. If that doesn't work out or you don't feel like waiting, we've got a network of buyers at Landmark Property Buyers.
