Hello Donna...the value of your home is determined by it's age, condition, size in square feet, amount of land included and the local market for property. Your best bet for getting an accurate market value is from a local Realtor who is familiar with your community. They will look up some information on recent sales of homes in your area and compare your home's features to the other homes that have been sold.
There are 55 houses listed for sale in Eight Mile, Al on www.Realtor.com and some of them are on Old Citronelle Hwy. If they are near where you live, their price might give you an idea about the value of your home. Let me know if you have any other questions...Dan
