Secondary and Tertiary Markets (TX)

Hey guys I am a recent college grad looking to break into the CRE industry and would love some feedback on some questions I have. I have recently been offered a spot with a smaller boutique brokerage that operates out of a major market in TX. They predominately focus on retail investment sales, both STNL and Multi-tenant, throughout the state and are a young and upcoming firm. They give all their brokers certain regions/markets to focus/operate in and the region they have available for me would be secondary and tertiary markets throughout the state. What are some pros and cons to working in these markets? Would it be hard to eventually transition into a major market down the line? How lucrative are these markets compared to a market like DFW?

I’m at the point where I am getting tired of interviewing with a lot of shops and just want to get started, but I obviously want to make sure I’m going into a good situation. Any feedback would be much appreciated. Thanks!
