For those who are considering renting as an option when you are moving to another location, my rule of thumb is "Its strictly a math problem. If I can't get enough rent to cover my costs, I sell. Why pay for others to live out of your wallet? While there may be some appreciation and the theory that someone else is paying your mortgage, you have to factor in, what if they lose a job and can't pay you? What if something needs repair or the tenant messes up the place. All of this costs. It's simply a math problem!
