Hi Stephanie - I am a long-distance flipper, based on California, working on my second flip in South Carolina.
Specifically, my investments are around the Charleston suburbs, and that area is certainly hot. I initially wanted to BRRRR or what-have-you, but found South Carolina to be difficult for non-owner occupied investments.
As for Mullins, I cannot say. A quick Google tells me that Mullins has no large employers, so you'd have to figure out where they commute to, and what would give them the means to buy a flipped property.
For flipping, my local realtor believes that foreclosures in South Carolina will hit the market in late spring to early summer. Of course, confirm that, make your own conclusions, talk to your attorney, or whatever.
If you move to a new locale, I would also think about establishing your team now...would you be seen as an outsider? Or is there a realtor or wholesaler or someone well connected who could get you on the early side of opportunities. I just think these small towns would be tight-knit.
Best of luck, and feel free to reach out if you wish to discuss further.
Erik
