What must a broker have if they operate one main real estate office and four branch offices?

In Louisiana, when a broker operates one main real estate office alongside multiple branch offices, it is necessary to have a specific licensing structure in place. The correct answer indicates that a broker must obtain a license for the main office in addition to a branch office license for each of the branch locations. This requirement ensures that each office operates under the proper legal and regulatory framework, providing accountability and maintaining professionalism within the industry.

Having a license for each branch office allows each location to conduct real estate transactions legally while adhering to state regulations. It also ensures that proper oversight and management are maintained by the broker over all operations across the different offices.

The other options may imply less adherence to the regulatory requirements, which could lead to complications and legal issues for the broker and their business. For example, while having one license for all offices may initially seem convenient, it does not comply with the legal necessities outlined by state regulations governing real estate practices.
