I do what Bob instructs.

Great photos, mls, maps, attributes, zoning,

Ask Endre Barath, Jr. -- he's The Land Man.   

Only thing to really do is put it in the MLS, only people interested in it will be looking for exactly that as they want to built a custom home. Other approach I have used is to use Linkedin or a professional network to reach out to developers, nice thing there is if you maintain a relationship with them you can sell them the lot and then sell the house they built on it later.

Use your MLS just as you would for a home but identify it as land without buildings. It's best to use your description and other advertising to feature things that make it attractive as a buildable lot. Examples: all utilities installed to property line, sewer hook up, level lot, view lot, etc.

MLS. Ours reaches out to thousands of websites out there

Start with 'FOR SALE'. Representative photos and all the facts. Post in the MLS and on our websites.
