Best In South Carolina Real Estate™: Charleston

53.6% of all seasonal homes in the Charleston tri-county are located in just three ZIP codes—ZIP 29455, 29438, and 29451. This isn’t just a trend; it’s a structural reordering of the region’s real estate landscape. According to ALEX Intelligence’s new analysis of 2024 Census data, the concentration of second homes in these ZIPs reflects a deepening spatial divide, where access to the seasonal core determines long-term value. This clustering isn’t random—it’s a feedback loop where more seasonal buyers attract more amenities, which attract more buyers. For investors and homeowners, this means location is no longer just about where you are, but whether you’re inside or outside the core. How does this dynamic affect your strategy?
