In Mississippi landlords do not hesitate to sue in justice court, a/k/a small claims court, and will go to circuit court if they need to.
It is harder for them to sue if you are from out of state. When I was in school half-a-dozen of us rented a large house, with all of us on the lease. Summer came and everyone bailed out. Two of us were from in state, so we’re the ones who got sued.
With that said, they will re-rent the apartment and you may only be out a month’s rent or maybe just your security deposit. Best thing to do is ask, beg, wheedle, and plead.
