Many home owners face this exact situation. Giving up on looking at homes in Clinton, TN is easy. However, we both know that's not the route to take. If you're having difficulty selling your home, then I would suggesting getting creative and getting someone to take over those payments. You can do this through a lease purchase or rent to own situation. Not only does this allow you to have someone take on those monthly payments and allow you to purchase a home in Clinton, it also puts a plan in place for you to potentially get your home sold in one of the worst real estate markets in history.
