Since you're not underwater or anything, you do have some options, thankfully. However, given quite how much selling and/or moving costs, you might be better served staying and getting a security system. It's not especially mustachian, but I believe some insurance companies give discounts on homeowner's insurance if you have them which could offset some of the cost (since they often also send alerts to the fire department if there's a problem) and it would provide peace of mind. It certainly did for me when I was first living without roommates in a fairly crime-ridden city.
Just a thought - a bit of a third option to simply staying or moving. Alternatively, robbers hate small dogs. Maybe you should get one of those? :)
