Linda, you know this is Trulia right? This is what I tell all of my clients, and I will tell you too because it sounds like you put a little too much stock in this website:
Please don't pay any attention to the values you see here, or on other sites like Zillow or Realtor.com.
These numbers are automatically calculated through special algorithms that really have no bearing on actual "fair market value". Whether you are buying or selling, the ONLY way to find out a home's value is to have a REALTOR do a FREE comparative market analysis (CMA).
Also...are you actually looking at the "For Sale" listing or just the public records info? Seems like you may be confused by the difference. If you are the listing agent you can manually edit your "For Sale" listing (not the public records info). However, it looks you aren't set up as an agent, but just a consumer. You may need to go back and register as an agent, and make sure your listings from your MLS syndicate here.
Good luck to you and your listing!
