Having a good relationship with your real estate agent can make the difference between a smooth transaction and a mess. If you're had a positive experience with an agent you've worked with in the past, it's natural to want to use that agent for your next home purchase or sale.
If you're making a cross-town move or a move to a neighboring community, your former agent may be a good choice if the agent specializes in the area where you'll be selling and the one in which you want to buy.
Sometimes, agents who do multiple transactions with clients offer a break on the commission to ensure your repeat business. However, the possibility of a modest savings shouldn't blind you to the pitfalls of working with an agent who is unfamiliar with the territory.
