I can't speak to the entire state, Charlotte is my turf. One big reason Charlotte is so popular right now is that from a lot of different angles, it is a sturdy, diverse economy that is rapidly growing. More people are moving here every day than we are building homes for so the price of homes, especially in the affordable price range, is going up. Our year over year appreciation for the Charlotte region is over 8% on average and some zip codes have seen a 30%+ increase year over year which is INSANE! With prices where they are and rents also increasing, you can still stand to cash flow as well, although there are certainly other areas of the country that have better cash flow. This market is a happy medium between appreciation and cash flow.
As previously mentioned, we have been known as a banking city and of course that is still strongly rooted here. There are also more and more diverse industries moving headquarters to Charlotte or companies that have been here a long time (Lance) that are growing.

As also previously mentioned, NC weather is very mild compared to other areas of the country. Charlotte was actually ranked in the top 10 cities in the world for quality of life, alongside Raleigh, in a recent study from the user-contributed database website Numbeo.

Just a few things about our area. Hope that helps!
