If you have plenty of time and are not in a hurry to sell the property, and would like to do very little work I would suggest listing it with a broker. They will be able to create a listing for the property, answer phone call and emails, and handle the closing. The downside of this approach is comes at a price and you typically only get local exposure and most real estate agents who deal with both land and homes will most likely put more effort into selling their homes as the commissions are greater.
Lack of advice or tools: You may miss an agent’s help throughout the process, starting with when you set a listing price. Online price calculators may not be sufficient to determine the fair market value of your home because they use completed sales, which tend to lag the market by a few months. Also, the algorithms don’t necessarily account for factors like curb appeal, landscaping, recent renovations, or school district lines.
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!
