I can send you a quick search for rentals in that area if you would like. I am not in the rental business but I would be happy to help you out. Here are 2 popular rental agencies as well.
I would also check Craigs list. If you would like me to send you what is in the MLS, just send me your email address directly. Be happy to help you out.
1. Search the MLS for condos/townhomes for rent. There are currently 5 for lease in Matthews/Mint Hill ranging from $890-$2295
2. Have you identify an area or complex where you want to live and see if there is an investor who would purchase a condo based on a long term lease for you.
