I live in Murfreesboro, TN which is about 30 miles from Nashville, How are values going for homes in my area?

I have a house that I have placed on the market which is 1305 sq. ft. I have done a lot of upgrades i.e. granite counter tops, tile flooring, new carpet and new paint. The front of the house is brick and the remainder is vinyl siding. It is on a corner lot with my 2 car garage coming in from the side. I have almost an acre (.44) of land with lots of landscaping. Any ideas about the value of my home?
