You can even go on-line and search for a real estate office in that area and call and ask for an agent that works Oakwood. Ask how many properties they have listed or sold in that area, then ask for references. An agent knows good questions to ask, and can aid in referring you to a good agent, plus agents are always networking and monitoring referral satisfaction. Plus, there is a large real estate company that was founded in Texas, not far from Oakwood, that may be able to assist your real estate needs in Texas.
Mary gave some good advice too, that an agent will save you some money by giving you a Comparable Market Analysis, but if you are more comfortable with an apraisal then do what you feel meets your needs. All the best to you..
