How Charleston compares to South Carolina

Across the 2 South Carolina markets we track, the average one-bedroom rent is about $1,400/month and the average vacancy rate is 5.8%. Charleston's $1,700 median is 21% above the South Carolina average of $1,400/month, and its 5.0% vacancy is tighter than the South Carolina norm of 5.8%.

• Gross annual rent (one unit, before vacancy): $20,400
• Vacancy-adjusted annual rent: $19,380
• Charleston rent vs South Carolina average: 21% above

With higher vacancy, Charleston tenants have options — so screening carefully and pricing competitively matters. Know your true cost and cap rate per unit before you set rent.

If your Charleston unit is rented below median and your DSCR is under 1.20, you have room to optimize. Mozongi REMA calculates DSCR, ROI, and cap rate automatically for every property.

Built for South Carolina landlords

Renting out property in Charleston comes with its own rules, and Mozongi REMA helps you stay organized around them:

• South Carolina's landlord-tenant statutes and the South Carolina housing or small claims court govern tenancies in Charleston — keep lease terms, dates, and renewals organized in one place.
• Rent increases — track current rents against the applicable annual guideline so every adjustment is documented and on time.
• Tenant records and documents — store leases, condition reports, and correspondence per unit.
• Every amount is tracked in USD.

Know whether your Charleston rental actually pays

Charleston purchase prices and rents both vary widely, so a property that looks fine on paper can quietly underperform. Mozongi REMA calculates net operating income, cap rate, and cash-on-cash return automatically — so you can see whether a Charleston unit is earning, breaking even, or costing you money, and decide what to do next with real numbers.
