In Maryland, a buyer's agent is paid for by the sellers. If you're not going to be paying for the services of a buyer's agent, then why not take advantage of it?
The purpose of an agent is to navigate the process and help you get from start to finish in as smooth a way as possible. Use your agent's experience, it can't hurt. They handle all of the paperwork, scheduling, monitoring of timelines, vendor recommendations, any objections from sellers - literally all of the stressful stuff! Take the opportunity if you are house hunting to hire an agent that's experienced, trustworthy and personable to help you navigate the deal. It's going to save you time, money, and anxiety.
