Truthfully, there are a myriad number of ways for you to get a reasonable idea of your home's value, especially today. Possibly the easiest way is to get the recent neighborhood sales information directly from your county recorder's office or any other government sponsored public site. To properly use the info you gather, simply compare and contrast a home or two of similar size, number of bedrooms and baths and almost identical features to your own. Be careful not to look at homes that sold have sold more than 6 months prior (the more recent the better- as the current market in most areas is still downward trending). Obviously, regardless of what price or value you set for your home, your home is truly only worth what a buyer is willing to pay. There are a number of other sites that gather this same information, but most do so for a fee.
Certainly your best and most accurate source is through a local realtor or two. Some people are afraid of a "sales pitch," from a real estate sales person, but let's face it, we all feel some sense of trepidation or fear when we go see our doctor, dentist or attorney, but we go to them anyway, because they are the professionals in their field. They are expected to know more than you do because that is their field of expertise. AND, Just like no two medical cases are exactly the same, no two homes are exactltly the same in every way. A professional Realtor can help you much better than you can help yourself. You certainly do not have to hire any of the Realtors you interview, but while you are on your computer , take a look at the statistics that show just how much money you may stand to lose by selling you home by owner instead of by Realtor. Best of luc...especially in this market.
