Dallas real estate agencies help in buying and selling residential and commercial property in Dallas and its suburban areas. Like real estate agencies elsewhere, they do not own or buy any property that they list. They work on commission for their clients. Within the broad buying and selling functions, the real estate agencies in Dallas help in relocation, moving, rentals, mortgages, and other realtor services like insurance. The range of options offered by Dallas real estate agents for residential property includes houses, apartments, condominiums, lakefront homes, and sometimes ranches, too. Dealings in commercial property are largely restricted to the business areas, and some of the newly developed and developing areas.

The Texas Real Estate Commission (TREC) is the state government agency that issues licenses to real estate agencies operating in the state of Texas. Hence, the real estate agencies in Dallas come within the purview of TREC. TREC requires real estate brokers and salespersons to have sufficient education that would make them eligible to hold a license to work as a real estate agent. This is to ensure that consumers of real estate agencies get to interact with qualified and competent agencies.

Merely holding a license issued by TREC does not qualify a real estate agency to be a realtor in Texas. To qualify as a realtor, a real estate agency or professional should be a member of the National Association of Realtors, the national real estate industry association. Most real estate agencies in Dallas are members of this association, apart from being members of the MetroTex Association of realtors, the association for North Texas real estate professionals, which also consists of the Greater Dallas Association of Realtors. The Texas Association of Realtors is a statewide organization with 80,000 members that serves as a platform for realtors in Texas, including those in Dallas.

Most of the real estate agencies in Dallas have individual websites that list all the properties that they advertise for selling or buying. The websites are helpful for non-Dallas based clients to find property listings in Dallas quickly.
