Your Agent should always show you the homes you are interested in. Your Agent should personally escort you to each home. Do Not rely on the Listing Agent to do your Agents job. You deserve a full time Agent who works just as hard as any other Agent. Make sure to interview your future Agent carefully and watch out for "Testiphonials". All my testimonials are real and I can give you actual references.
If you want full and Ethical Representation then Hire me! I do a full service job at half the commission.

Please interview a few agents if you like, when interviewing other agents, ask how they conduct their business and what services they will provide to you. Here is a list of what a true agent should do. This will give you a good idea of how the process will go and help set your expectations.
