Let's be honest: South Carolina isn't cheap. But within that premium market, there are cities where your dollar stretches meaningfully further.

Tax burden isn't just income tax. We combine three layers: state income tax (6.4% in Charleston), combined state+local sales tax (7.44%), and effective property tax (0.52%). At 6.4% state income tax, the real differentiator becomes sales and property tax rates. On a $75,000 — for better or worse — salary, the estimated take-home in #1 Charleston is $52,910/year.
Below the radar, but not for long.
