You might be hard pressed to find some good rentals in southeast charlotte for $900.00 a month. Not that they are not out there but scarce. I would say you are probably safely looking around $1000.00 to $1500.00 depending on where and the amenities and size of the house.
Depends on the neighborhood, honestly. You may need to increase your budget for Southeast Charlotte, in general. If you're still interested I can give you the contact info for a good property management firm in Charlotte. Shoot me an email at VictorAhdieh@yahoo.com. Best wishes, Victor
