Frankly, Let's be honest: South Carolina isn't cheap. But within that premium market, there are cities where your dollar stretches meaningfully further. Charleston proves it with a cost index of 121, the lowest in South Carolina, and we've ranked all 3 contenders to help you find the best deal in an expensive landscape. Quietly competitive.
Here's Charleston by the numbers — and there's a lot to like. Cost index: 121. Rent: $2,127/month. Income: $90,038/year. Home price: $581,145. Population: 155,369.

The ranking uses a composite of 2026 data from Census Bureau population/income surveys, Zillow rent and home price indices, BLS salary benchmarks, and Tax Foundation tax rates.

Each city profile below links to the full detail page with 12-month trends, salary breakdowns, and cost category comparisons. Can we talk about how broken the conversation around affordability is? A city gets labeled 'cheap' and suddenly everyone assumes there's a catch — bad schools, no jobs, nothing to do. But look at the income numbers here. Look at the cost categories. This isn't a budget consolation prize. It's a genuine alternative to the coastal rat race, and the data makes that case more convincingly than any think piece.
There's more to the story, though. The 3 cities we track in South Carolina paint a clearly affordable picture. Average cost index: 105. Median rent: $1,752/month — we had to double-check this one — . Household income: $69,493. South Carolina is known for Lowcountry charm and migration-driven growth — and the data backs that reputation convincingly.
Bottom line: Charleston leads this ranking for clear, data-backed reasons — but the "best" city depends on your priorities. It lines up with what you'd expect.
