What most agents do



Most agents will probably publish your listing in the Multiple Listing Service (MLS).
The quality of these listings may vary, we have seen listings without pictures, in spite that agents can be fined for that.
It is a well-known fact that most real estate transactions are concluded by agents, over an agreement known as the Internet Data Exchange (IDX), so publication in the MLS is an effective tool, but, in an economy that is not booming, it is not enough.
Although the MLS is restricted to realtors, listings are published to realtor.com, which is the public facade of NAR, and publishes all listings nation-wide.
