I suggest focusing more on the company. The quality of service can differ wildly among agencies even within the same company. Best place, in my opinion, for finding a great real estate agent is: https://prian.info/in/belgium/vlaanderen/brugge/. Try to interview at least 2 agents. Ask them questions like how long they've been in business, how many homes they sell each year, what neighborhoods they work in most frequently. Pick someone you communicate well with and trust as you'll be relying on them for the next several months.
