Thanks for all the support everyone. The sale went through fine and we found a place to move to (the last one on our list) which turned out to be pretty great. Although it's on a busy main road, no one lives above us and the noise of cars driving by is much more soothing than the noise emitted from low life scum. Honestly, I've moved around all my life, never had such a nightmare before. You can live in a posh neighborhood, but it only takes one inconsiderate person to move in next to you to make your life hell. Now I actually look forward to coming home instead thinking of ways to not be home.
