Should I just hire the agent who sold my neighbor's house?

Hiring the agent who sold your neighbor's house can be a reasonable starting point, since they already have recent, hyperlocal data on your street, but it should not be the only reason you choose them. Ask how that sale actually went, what the home sold for relative to comparable homes, and how long it took, rather than assuming a nearby sale means a good outcome. Your home's condition and your goals may call for a different approach than your neighbor's did. Joel Boss can show you his own track record on your specific street if he has one.
