Population: 129,330. The strongest category is Housing at 85; the most expensive is Healthcare at 97.

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.
A closer look at Columbia: the cost index of 85 breaks down to a Housing index of 85 (strongest category) and a Healthcare index of 97 (weakest). Median rent is $1,459/month — 23% below the national median — while household income sits at $55,653, meaning locals spend about 31% of income on rent. That exceeds the recommended 30% threshold — affordability here depends on earning above the median.
Real talk: the 3.5× rule is a conservative benchmark: lenders often approve up to 4-5× income, but 3.5× keeps monthly payments safely under 28% of gross income at typical rates. On $60K, that means targeting homes under $210,000. Columbia offers a median home at $226,769 — a 3.8× ratio with room to spare.
Bottom line: Columbia leads this ranking for clear, data-backed reasons — but the "best" city depends on your priorities. Fairly typical for a city this size.

We rank cities by their home-price-to-income ratio (median home price ÷ median household income). A lower ratio means homes are more attainable relative to local earnings. The standard benchmark is 3-5×; above 5× is considered stretched. All data is sourced from federal agencies and verified research institutions. Cost of living indices are normalized to 100 (national median) using Zillow rent as the primary signal, with sub-category adjustments derived from regional BLS price data. Rankings are updated monthly as new data is released.
