Lately I have been recommending Postlets to my clients looking for additional marketing exposure. Their website allows you to post properties to their website for free. The big bonus comes in that once a property is posted it is automatically picked up by other property classified ad sites like Oodle, Google Base, and Propsmart. Another added benefit is that they generate html code that can be cut and pasted into a Craig's list ad. This allows you to easily communicate your property information in Craigslist with pictures without having to know how to generate any computer code.
