You are a retiree. What are the tax implications of moving from South Carolina to North Carolina? The two states treat retirees differently, so you could find yourself with significant changes in taxable income. That is research you need to do for yourself based on where your income comes from.
Do you live primarily off of Social Security benefits? A private pension? A government pension? 401k income? Roth IRA income? Traditional IRA income? Do you keep most of your money in cash? A savings account? Bonds?
As a 30 year old, I find North Carolina treats the working man a lot better than South Carolina does. NC drastically overhauled their entire tax structure a few years ago. SC's income tax is brutal while NC is moving to a much more fair use-based tax situation. Retirees may be a totally different situation. You could be significantly changing your taxable income situation, and only you can determine that.
I strongly suggest you do A LOT of research. SC is generally regarded as much friendlier toward retirees, so you could be taking a big hit by moving North and starting off in the hole. Unless...you are structured uniquely, which most retirees don't take the time to structure their assets in a tax-advantaged way, unfortunately.

Then there is the fact that you're moving from a location that "has it all" to a location that has considerably less of the "big chains." How important is trendiness to you versus a slower pace of life?
What about property values? Demographics? Road quality? Population density?
All of these things only you can determine.
