While I would love to solicit you to be your REALTOR in Clay county RIGHT NOW, I think it's important that you investigate the two areas you are considering and then visit both of them, if you like both areas after some research. They are very different. I am in Clay county so I have direct knowledge of it, but not Calhoun county. Clay county - Brasstown, Warne, Hayesville - are in the mountains with Lake Chatuge, rivers, creeks, and higher elevation. Brasstown is also very close to Cherokee county, NC so I have included that as an option for your review as well.
You can see some really good stats on all three counties at the links below... you may have to cut and paste them into your browser bar on internet explorer if the link doesn't connect from here...

If you want a neutral place to search for property in any location, go to www.realtor.com and you can see all properties, as our MLS (Multiple Listing Services) overflow to this site and would cover all areas. Then, if you need a REALTOR and if you want to purchase property in Clay county, and you really do need a REALTOR as most properties are listed with REALTORS anyway - you can see that REALTORS in this area are more than willing to be available for you. You need a REALTOR who is working for your best interest as a Buyers Agent. It doesn't cost you anything, but if a REALTOR isn't working for you, they are working for the Seller.
I'm sure you can find just the right place with the help of a sincere professional. Best of luck to you and if you have any more questions, we're here for you in Clay & Cherokee counties! I am licensed in Georgia as well which is just over the line (Young Harris and Hiawassee, GA). You may want to research those areas as well as there are differences that can benefit you depending on your personal needs.
