The Multiple Listing System is the database of listings that Real Estate Agents and Brokers access. This is the most comprehensive database to find a home to buy or rent, or to list a house to sell or rent. It does also have capability to access commercial real estate listings. Please beware of any advertisement web portals out there (for example: zillow, homes.com, realestate.com, etc.) They are not the MLS we use.
You can search the MLS websites (mobile version available)
Make sure you enable GPS Location on your smart phone to experience great Current Location search.
