A real, structural affordability advantage for fixed-income retirees

Summerville's meaningfully lower housing costs ($344,000-$425,000 median across sources) and rent ($1,666/month average) than Mount Pleasant's own figures in this dataset represent a real, structural affordability advantage for retirees on a fixed income, alongside a genuinely lower homeowners-insurance cost given the town's more inland position.

South Carolina's real tax treatment for retirees

South Carolina fully exempts Social Security income from state tax, and residents 65+ get real, coordinated (not simply additive) deductions capped at $15,000 combined for a single filer -- the same statewide structure that applies in Summerville as elsewhere in this dataset.

Weigh the real crime picture directly

Summerville's D/C- crime grading (depending on source) is a real, disclosed factor retirees prioritizing the lowest-crime option should weigh directly -- Mount Pleasant's A+ grade or Bluffton's A- grade (both built elsewhere in this dataset) may be a better fit for a retiree whose top priority is the lowest available absolute crime statistics, even though Summerville offers real affordability and hazard advantages in exchange.
