Let's be honest: South Carolina isn't cheap. But within that premium market, there are cities where your dollar stretches meaningfully further. Columbia proves it with a cost index of 85, the lowest in South Carolina, and we've ranked all 3 contenders to help you find the best deal in an expensive landscape.
At $1,459/month for rent and a cost index of 85, Columbia is pretty much what you'd expect from a mid-size city in this part of the country. Take it or leave it — the data is what it is. Income is $55,653. That alone makes it worth considering.
Rent data is sourced from Zillow's Observed Rent Index (ZORI), which tracks the median rent across all active listings — not just new leases. This gives a more representative and stable signal than asking prices alone. Columbia: $1,459/mo, North Charleston: $1,670/mo, Charleston: $2,127/mo. The cheapest city here is $436 under the national median — that's $5,232/year in savings on rent alone.
The counter-argument is worth hearing: Here's the state-level backdrop: South Carolina averages a 102 cost index, $1,752/mo rent, and $69,493 income across 3 cities. That's $143 less than the national rent average. Lowcountry charm and migration-driven growth — and that context shapes every city in this ranking.
