TweetLister is geared specifically for real estate professionals to get their listings to fit into a 140 character tweet and still give a link to all the necessary information. The agent is able to promote all their property listings, or just individual ones. They can even schedule when they should be delivered.
TweetLister costs the agent $9.9/month and is able to pull in all their MLS listings automatically. Any type of property is possible, with the ability to post to mutiple accounts to slice and dice your buyers up to following different accounts for different property types.
Generate Leads with Enhanced Detail Pages! Include multiple photos, detailed descriptions, more property features and useful tools, such as a calculator, school reports, Google map and WalkScore™. And it gives visitors several ways to contact you: directly to your phone and email; through our contact form, which also collects all contact information into a downloadable Excel file; and through two available links back to your agent or property website, virtual tour — or any other web address that provides information about you or your listing.
If you are an agent, give it a shot and let us know. It looks somewhat useful and promising. If the MLS had RSS feeds you could do place listings in Twitter for free, but most MLS sites do not.
