Which Kentucky broker is NOT required to maintain a place of business in the state?

The correct choice is Lynn, who maintains her place of business in another state. According to Kentucky real estate laws, a broker must have a physical place of business within the state of Kentucky if they are conducting business there. Lynn's situation, where she conducts her business from another state, does not fulfill this requirement.

Brokers like Jake, who has a business license in Kentucky, and Mark, a resident of Kentucky, must maintain a place of business within the state as they are either licensed or residents engaging in real estate activities subject to state regulations. Similarly, Sara, who operates in multiple states, is often required to maintain a place of business in each state where she is licensed unless her operations automatically comply with interstate provisions. However, her obligations may be more complex, but the requirement is generally upheld. Therefore, Lynn stands out as the only broker not mandated to have a local business address in Kentucky.
