FInding vacant lots, commercial and billboard properties

[Mercedez H.]

hello,

I am new to Real Estate and wanted to know how do people find billboard properties, and what are the best ways to find vacant lots ( and what to look for when buying) I was thinking of putting mobile homes on a vacant lot ( any thoughts?) I would also like to own a billboard property and was wondering how to go about that it would I just buy land and look for bilboreda to put up my self? And is being an agent for a commercial property a good way to make money and how do people find those listings? It’s all confusing and I don’t know where to start and google isn’t no help.
