As others have mentioned, consider renting it out. It may depend on the financials, and how that would work out in your situation, but at least give it consideration and run the numbers.
Also, you may want to consider trying to do a HARP refinance on it. If you are eligible, this may save you money, lower your interest rate, and/or lock in your interest rate (if it's not already). You can read more about it here: http://richardschulman.com/2011/10/25/exciting-changes-to-the-harp-refinance-program/ and contact your lender for more information too.
