Trulia give very easy access to this information. Go to http://www.trulia.com, and search for your city, or even better your ZIP. Then, just check the box under the map that says "recently sold homes" and you have a map with both the for sale and sold properties in the area. From there, it can be helpful to zoom in the map onto your neighborhood so you don't have to wade through all the other stuff in your city.
In some communities prices are public record. Call your county records office and ask them if sales prices are public information. They can usually help guide you to ways to look at the records. This may be the best way if your community is new or still being built out with lots of sales directly from builder to buyer. You might also want to ask a Realtor first, especially if you are in a resale community where most homes are sold by Realtors. We normally will have good information on sales prices, trends and can help you determine the value of your home. Let me know if I can get you connected to a great Realtor in your area.
