I would google furnished leasing companies in the Charlotte area. There are a ton of property management companies out there that have fully furnished units in their inventory. I would also check with the luxury apartment rentals, I think that they have options for furnished leases(can get quite pricey however). I work with a professional in the area by the name of Jarrod Clay with CORT, thier website might be a good place to start! http://www.cort.com/relocation
If me or my team can be of any assistance do not hesitate to reach out! Happy shopping!
