Using a realtor is a good option if you do not have the time, patience, tools, and ability to market the home yourself. In this market, it's all about exposure and getting the most people to view your home in order to find your buyer. That is really all a realtor is for, in my opinion.....Someone to market your home. I decided to use one recently in selling a property I rehabbed, and wasn't too happy with the experience. I hired her to free up my time to do other things, and found that I had to constantly push her to do anything more than list it on the MLS, and do not feel that she did enough to earn what she made on the deal. I am not so sure I would use one agian. You can sell youself if you keep these things in mind. Finding a real estate agent that truely has your best interest, vs their own, at heart is very difficult, since many are experincing a dramatic decline in income due to market conditions. I would be very careful when screening realtors to find one you can trust if you go that route. There are many tools available these days to sell it yourself.
Good Luck
