South Carolina 4plexes: House Hacking in South Carolina

Why Consider a 4plex in South Carolina?

• Ongoing rental demand in Charleston, Columbia, and Greenville, with university, military, and manufacturing employers
• Ability to use FHA and other low-down-payment loans when owner-occupying
• Potential to significantly reduce or eliminate your personal housing cost
• A growing Southeast market with long-term ownership appeal

Local Advantages

With about 5.6 million residents (U.S. Census Bureau estimates), South Carolina has grown steadily as newcomers arrive along the I-85 corridor and the coast. Charleston's port and tourism economy, Columbia's role as state capital and university city, and Greenville's manufacturing growth each support year-round renters. A well-chosen 4plex can generate meaningful income from the rental units while you live in the fourth.

South Carolina has no statewide rent control, and landlord-tenant relations are governed by the state's Residential Landlord and Tenant Act, so owners should review its current notice and deposit rules. On the cost side, coastal hurricane exposure and flood zones make wind and flood insurance a major underwriting item for four-unit properties near the coast, and flood-zone status should be checked for any property under consideration.

Financing a South Carolina 4plex

If you plan to live in one unit, you may qualify for residential loan programs (including FHA) with lower down payments than commercial financing requires. FHA is a federal program, and FHA loan limits are set at the county level, not the state level, so the limit that applies depends on the county where the property sits. Down-payment assistance programs vary: buyers should check their state housing finance agency, because whether a given program allows four-unit properties varies by program. A lender familiar with four-unit properties in the area can walk through the owner-occupancy rules and the paperwork involved.

Loan and Down Payment Programs in South Carolina

SC Housing, the South Carolina State Housing Finance and Development Authority, offers a Home Loan: a 30-year, fixed-rate mortgage available statewide through approved lenders, which must be insured or guaranteed by FHA, VA, or USDA, or meet Fannie Mae HFA Preferred or Freddie Mac HFA Advantage guidelines. Its Down Payment Assistance is a secondary loan that is fully forgiven if the borrower stays in the property for 15 years. One program to skip for now: Palmetto Heroes, the reduced-rate program for teachers, nurses, first responders, military members, and veterans, is currently closed for 2026. 4plex fit: third-party summaries of SC Housing eligibility list stick-built single-family dwellings, off-frame modular homes, patio and townhomes, and approved condominiums — no four-unit property type is listed — so do not count on SC Housing assistance layering onto a four-unit purchase; confirm with SC Housing or a participating lender.

The national programs are where a four-unit purchase usually finds its financing. FHA permits a down payment as low as 3.5% of the purchase price on 1-4 unit properties and applies a self-sufficiency test to three- and four-unit purchases. VA-backed purchase loans need no down payment when the sale price is at or below the appraised value, require no private mortgage insurance, and can finance a home with up to four units for a borrower who lives in one. Standard conventional loans cover owner-occupied four-unit properties with a larger down payment than a one-unit purchase. Fannie Mae's HomeReady and Freddie Mac's Home Possible both advertise down payments as low as 3% with income capped at 80% of area median income, but both write that 3% figure for one-unit homes — plan on a larger down payment for four units and confirm with a lender.

How Many Cities Are in South Carolina?

South Carolina has 271 incorporated cities and towns, as counted by the Municipal Association of South Carolina, which represents all of them. The figure counts incorporated municipalities only; unincorporated communities, however large, are not cities in this count. Source: Municipal Association of South Carolina, History.

How Many Counties Are in South Carolina?

South Carolina has 46 counties, and the South Carolina Association of Counties counts all 46 among its members. Counties operate under four forms of government — council, council-supervisor, council-administrator, and council-manager — and every county operates on a July 1 to June 30 fiscal year.

Fire Insurance Costs in South Carolina

South Carolina's average annual homeowners premium was $3,092 at the end of 2025, per Insurify's 2026 price projections, with a further rise projected for the end of 2026. The statewide average hides a sharp coastal-inland split: hurricane wind and storm surge exposure drives the highest premiums in Lowcountry and Grand Strand communities, while inland areas around Columbia and Greenville price materially lower. One gap to budget for separately: a standard homeowners policy does not cover flood damage, so a coastal or low-lying four-unit property will usually need separate flood coverage on top of the homeowners premium. Insurify's average reflects a typical single-family home's dwelling coverage; a four-unit property's premium will differ, so get a property-specific quote.
