Wayne is right. Given the specs of your home and its proximity to the bridge, there are definitely buyers out there right now. If you have not done so already, your home needs to be on the market no later than early September.
A word to the wise, be prepared for people to ask for closing costs and possibly haggle with price. On the flip side, you may be able to do the same thing while you are buying. Just remember to price your home fairly. A well priced house will sell faster and get you moving up to your next home.
I also work in Gloucester. You can check out some of my Gloucester listings at: http://www.HomeSearchVirginia.com.
Have a great one!
