A couple relying on two Social Security checks is working with a fixed monthly income, and in South Carolina that money goes furthest in cities where rent, home values, and everyday costs stay manageable.
The five below pair waterfront settings and walkable cores with a state tax rule that helps you save money in retirement, and each one looks different once the numbers land on paper.

Rock Hill, South Carolina
Median rent: $1,421
Average home value: $319,114.35
Rock Hill carries college-town energy from a local college campus, and its waterfront parks along the Catawba River give retirees wooded trails and river access without leaving town. A walkable downtown with shops and dining sits just off the interstate corridor that runs toward nearby Charlotte, so a small-city pace comes with a bigger city in reach.
South Carolina does not tax Social Security benefits, though other income is still subject to the state income tax. A regional hospital and health system serves the area, covering routine and emergency care.
The cost of living score here lands at 100.4, or 0.4% above the national average, so a fixed income faces roughly typical U.S. prices.
Columbia, South Carolina
Median rent: $1,249
Average home value: $222,939.58
As the state capital, Columbia pairs a government and business core downtown with college-town energy from a local college campus. The city sits where the Broad and Saluda rivers join to form the Congaree River, and waterfront parks and paved trails line those waterways close to downtown, good for an easy walk, a bike ride or a paddle.
South Carolina does not tax Social Security benefits, while other income remains subject to the state income tax. Multiple regional hospital systems in and around the city provide general and specialty care.
Columbia's cost of living score of 87.4 puts the total cost of housing, food, transportation, health care, and other necessities about 12.6% below the national average.
Greenville, South Carolina
Median rent: $1,404
Average home value: $318,309.19
Greenville's downtown wraps around a river cutting through the city center, with waterfront parks, trails, waterfalls, and greenways giving the core a walkable, garden-like feel. The river rises in the foothills of the Blue Ridge Mountains northwest of the city, so mountain scenery sits close by, and a nearby college feeds the restaurant and cultural scene.
Social Security benefits are excluded from South Carolina taxable income, though the state still taxes other income. A regional hospital system serves the area, and area hospitals offer emergency and specialty care.
The cost of living score of 91.3 runs about 8.7% below the national average, which gives a fixed income a little more room on everyday expenses.
North Charleston, South Carolina
Median rent: $1,519
Average home value: $303,937.65
Bordered by the Cooper River to the east and the Ashley River to the west, North Charleston has a waterfront setting of its own, plus college-town energy from a local college and a working-port, industrial character tied to nearby Charleston Harbor. It is a way to stay close to the water and to big-city amenities while keeping a foot in a working, unfussy town.
South Carolina fully exempts Social Security benefits from state income tax, though other income is still taxed. A regional hospital system serves the area, with additional major medical facilities nearby in the greater Charleston region.
The cost of living score of 112 sits about 12% above the U.S. average, so a paid-off home does a lot of work in a budget here.
Charleston, South Carolina
Median rent: $1,887
Average home value: $572,367.05
Charleston sits on a peninsula where the Ashley and Cooper Rivers meet to form a large natural harbor opening to the Atlantic. Downtown carries a walkable, history-rich atmosphere with college-town energy from a local college, preserved historic architecture, and waterfront parks and trails along the harbor and marshes.
The state does not tax Social Security benefits, though Charleston residents still owe South Carolina income tax on other income. A regional academic health system based in the area provides hospital and specialty medical services.
A cost of living score of 112, about 12% above the U.S. average, plus home values north of half a million dollars, means Social Security alone stretches thin unless the mortgage is already gone.
Bottom line
South Carolina's appeal for a Social Security budget starts with the tax rule: senior benefits are not taxed at the state level, which leaves more of a monthly check for housing, food, and health care. From there, the picture depends on the city, with cost of living scores in these five ranging from well below the national average to roughly 12% above it.
Before making a move, price out actual listings, get a real property insurance quote, and check what local health care access looks like in the specific town under consideration. The numbers here are a starting point, and neighborhood-level differences can shift the math further.
