When most people are ready to sell their houses, they enlist the services of a real estate agent to get the property sold. Good agents can be worth their commission if they know how to prepare the property for sale, market it, and get it sold for top dollar. Unlike when you’re a home buyer, your interests (as a seller) are aligned with a good agent’s interests — the more you sell the property for, the more you net from the sale, and the more the agent gets paid.
Given how much homes actually cost (and how much they cost to sell and buy), you owe it to yourself to have a good agent representing you in the sale of your house. Be sure that the agent you select is not currently listing so many other properties for sale that the agent lacks enough time to properly service your listing. Also, the agent you worked with when you bought the home is not necessarily the best agent to hire when you sell it. Different steps and expertise are required to sell (rather than buy) a house.
