When people are selling their homes, they hear a lot about the value of staging to make the home look better and to speed up the sale process. While you can’t really “stage” your land — unless you want to strategically place a few cows or sheep here and there to make farmland look more “farmy” — there are several things you can do to speed up the process of selling your land.
You can also look to certain companies and organizations that have a concentration of people that may fall in the above mentioned roles such as investment companies (i.e. Charles Schwab, Fidelity), financial advising companies (i.e. Morgan Stanley, Merrill Lynch). There may be a higher concentration of people who can both afford and want to build their own custom homes or to build income-producing properties. Try linking yourself to financial advisors who may already know of people who have these types of dreams. This isn't a comprehensive answer of all the possibilities but just some thoughts. Good luck!
