As it happens, CNN Money just launched a Best Places to Retire feature with listing data powered by Trulia! Here's a direct link to their Memphis page. Hopefully that'll get you started.
My husband and I personally live in (and build) a beautiful NEW home (NOT a MCMansion on a postage stamp) on acreage, in Hampton Roads Estates, which is something you will not find closer to the big cities. While it is not mountainous, we have nice hills and trees. We are considered to be in the "Valley". I have been here 20 years and only recall 2 really "significant" snowfalls.
If I can help any more, let me know! Our neighborhood has a website. I will try and insert it.
