Kathy,
You didn't identify why you might want the comparable values. If you are looking to see if your tax assessment is in line with others the process may be slightly different from getting an idea of your current market value. There have been previous Trulia discussions on the topic that you can investigate.
I'm going to assume you might be considering a refinance or possbile sale for your purposes. At best I can only provide you a partial 'how to' procedure. These days, most real estate websites of local brokerages allow you to look up sold listings. You simply have to target the area within a reasonable distance of your home. Be careful that you don't cross a 'neighborhood boundary' that implies a more or less desireable location if possible. You also want to limit your historical references to the past 6 months at most. If the sample is not large enough then extend the time period but beware that the market was an entirely different animal pre-August 2007.
Your second step is weeding through the search results to see how the homes compare with regards to amenities, size, age and other details. Beyond that comes the knowledge of the interior condition of each comparable home. Is the kitchen updated? How large are the closets? I'm sure you get the idea. These finer elements are hard to determine from any available on-line photos or text versus first-hand viewing. Pictures can be deceiving both positively or negatively.
If your need for a market valuation is not immediate, you might want to plan attending future open houses of homes in your area. Then you can assess what their listing prices are and monitor how well the homes hold their prices when sold. One thing you may never know is any concessions made like closing cost credits or work orders that go undetected to the general public. These are very commonplace in the current market. Therefore, your correct valuation may vary up to 6% from the number you achieve. (SIx percent is largest amount a buyer can receive for closing costs if they have mustered a 20% down. If the down is any lower than the cap is 3%.) And that's assuming you've done a good job in an objective fashion.
You of course have the option to involve a realtor familiar with your neighborhood. Or you could use any of the on-line services for valuation though I'm not a fan and don't believe you'll get the accuracy you want. Since price is the most critical element of a successful sale and your home is a highly valuable asset, think hard before you go it alone.
Hope that helps!
