village at lake wylie does shorter term leases too. my parents lived there while there a house in lake wylie was being built. i think they did a 3 month and went month to month. yes, there are some questionable beings around but like you said, they're everywhere
something to think about... there is no light at the entrance/exit of the village apts and turning left on hwy 49 in the morning can be very tricky. not sure what times you would be leaving but i would certainly drive it during the times you would be leaving so you know what to expect.
good luck!
