California regional multiple listing service (CRMLS) has been created when three existing regional multiple listing services merged. These companies were Interval International, Realtytrac, and Netquote. Together, they offered the same types of services and were able to provide the same types of features on the site. In November of 2010, the companies merged to form one giant company. Now, with the Showcase IDX CRMLS free trial service, you can become a member for free and begin searching any time you want.

Multiple Listings Services will list properties for sale to real estate investors, without ever having to contact each property individually. Instead, when someone searches for properties in your town or city, they will see all of the properties that are listed within a single MLS. They will also be able to search by category so that they are able to narrow their results to the type of property that they are looking for. The free service is offered by the three largest members of the CRMLS company. Members get access to over 800 properties in more than one hundred categories. This makes it easy to find properties according to your specific criteria. Members can also save their favorite listings to the service and use it again in the future when they need to look up specific properties again.
