North Charleston, SC Cap Rate 3.82%
North Charleston is the structural industrial-and-suburban alternative to Charleston SC — anchored by Boeing's 787 final assembly plant, Joint Base Charleston, and the broader Port of Charleston logistics economy. Meaningfully cheaper than Charleston proper. The 3.82% cap rate at a $430,000 median price keeps the 0.46% rent-to-price ratio closer to functional than Charleston proper. Population growth at 1.8%/yr is strong, helped by both Boeing supplier-cluster employment and Charleston-metro spillover.
Employment is anchored by Boeing South Carolina (the 787 Dreamliner final assembly line — the only Boeing widebody assembly facility outside Washington state; with the broader supplier ecosystem; a major engineering and skilled-trades employer for the metro), Joint Base Charleston (the merged Air Force and Navy installation — Charleston Air Force Base hosts C-17 Globemaster operations and the Naval Weapons Station Charleston hosts submarine and special-operations training), the broader Port of Charleston / Wando Welch Terminal logistics economy, Trident Medical Center, the broader Charleston County government, Container terminal operations, the broader Charleston metro spillover for retail and services. Submarkets stratify cleanly: the Park Circle area is gentrifying walkable urban-historic with strong appreciation; the broader North Charleston / Hanahan suburbs draw Boeing-supplier professional family rentals; the broader Goose Creek and Summerville areas extend the metro with newer construction; the central and parts of west North Charleston offer deeper-value workforce inventory.
South Carolina property tax at 0.58% is moderate at the metro level, but the 4% (owner-occupied) vs 6% (non-owner-occupied) assessment-ratio gap is meaningful — non-occupant investors pay materially more than the headline rate suggests. SC state income tax is graduated with a top rate near 6.5%, with a phase-down underway. Insurance is the dominant operational variable for waterfront and flood-zone properties — North Charleston has hurricane exposure (Hurricane Hugo in 1989 is the catastrophic reference; broader Charleston-area insurance has tightened post-2020). Get a binder quote per address. The structural advantages: Boeing's long-term commitment to South Carolina appears durable (the 787 program continues, and Boeing has continued investing in SC operations); Joint Base Charleston's mission concentration makes it relatively durable against BRAC; cost basis is materially below Charleston proper; sustained Charleston-metro growth provides demand. The structural risks: Boeing concentration matters (any major 787 program shift would affect supplier employment); hurricane and flood exposure are real. For investors who want Charleston-metro exposure at cash-flow math closer to functional, North Charleston is the most defensible Charleston-metro alternative.

2026 Market Update: North Charleston
North Charleston's 0.5% rent-to-price ratio is well below the 1% rule. At median prices of $430,000, the $1,970/mo rent produces only $1,367/mo in NOI. Investors here need to target below-median properties or pursue value-add strategies to make the numbers work.
At current rates, a 20% down conventional loan ($86K at 7%) would result in approximately $-921/mo cash flow — negative at median prices. Larger down payments, seller financing, or buying 15–25% below median are strategies to turn the numbers positive.
The 18.2x gross rent multiplier and 5.5% vacancy rate position North Charleston as a growth-dependent market. With annual appreciation at 3.6%, total returns (cash flow + equity growth) run approximately 7.4% before financing leverage.
Deal Modeling & Scenarios for North Charleston
All figures below are computed from North Charleston's real market medians. Use them as a baseline; override with property-specific numbers in the calculators.
Property Tax Bill in Real Dollars
At 0.58% effective rate on the $430,000 median price, the annual tax bill is $2,494 — that's very low (bottom 15% of US markets) (-45% vs the national average of ~1.06%). Verify the actual assessed value before purchase; sale-triggered reassessments can push the bill higher than the seller's current statement.
5-Year Cap Rate Trajectory
If North Charleston continues appreciating at 3.6%/yr while rents grow at a conservative 3%/yr, cap rate compresses as price growth outpaces rent. Year-by-year projection at the median:
| Year | Est. Price | Est. Rent/Mo | Cap Rate |
|---|---|---|---|
| Today | $430K | $1,970 | 3.8% |
| Year 1 | $445K | $2,029 | 3.8% |
| Year 2 | $462K | $2,090 | 3.8% |
| Year 3 | $478K | $2,153 | 3.8% |
| Year 4 | $495K | $2,217 | 3.7% |
| Year 5 | $513K | $2,284 | 3.7% |
Three Financing Scenarios
Same median-priced North Charleston property — different capital structures. All-cash maximizes cap rate. Leverage trades cash flow for higher cash-on-cash return when the spread between cap rate and borrowing cost is positive.
| Scenario | Cash Invested | Monthly Cash Flow | Annual CF | Cash-on-Cash |
|---|---|---|---|---|
| All cash | $430K | $1,367 | $16,406 | 3.8% |
| 20% down conventional @ 7% | $99K | $-920 | $-11,045 | -11.2% |
| 25% down DSCR @ 8.5% | $125K | $-1,113 | $-13,355 | -10.7% |
Three Price Tiers: Below, At, and Above the Median
Properties don't always trade at the median. Lower-priced units typically offer higher cap rates but harder operations; higher-priced properties tend to compress cap rates while attracting better tenants. All-cash assumptions below:
| Tier | Price | Rent/Mo | NOI/Yr | Cap Rate | Monthly CF |
|---|---|---|---|---|---|
| Below median (~75% price) | $323K | $1,675 | $12,618 | 3.9% | $1,052 |
| At median | $430K | $1,970 | $14,343 | 3.3% | $1,195 |
| Above median (~125% price) | $538K | $2,266 | $16,078 | 3.0% | $1,340 |
Total Return Over a 5-Year Hold
Cap rate is just one piece. Real estate returns come from four sources: cash flow, appreciation, principal paydown, and tax benefits. Assuming 20% down conventional financing at 7% and a 5-year hold at North Charleston's historical appreciation rate of 3.6%:
On a $86K down payment, that's a 62.5% total ROI over 5 years (not annualized). Tax benefits from depreciation are additional and depend on your personal tax bracket.

Is North Charleston a Good Place to Invest in Rental Property?
North Charleston, SC has a population of 118,000 and has been growing at 1.8% annually — above the national average, suggesting steady demand pressure on housing. The median home price of $430,000 paired with median rents of $1,970/mo produces an estimated cap rate of 3.82%.
Property taxes at 0.58% are well below the national average of ~1.1%, providing a meaningful cash flow advantage many investors overlook. The vacancy rate of 5.5% is moderate and within normal parameters for a healthy rental market.
At a price-to-income ratio of 8.8x, homes cost about 8.8 times the local median income of $48,600. This elevated ratio means homeownership is stretched, supporting rental demand but limiting buyer pools. Home values have appreciated at roughly 3.6% annually. Above-average appreciation adds an equity component to total returns, though deals should still pencil on cash flow alone.
Bottom line: At current median prices, North Charleston is challenging for pure cash flow investing. Consider BRRRR strategies with below-market purchases, or look at neighboring metros with stronger price-to-rent ratios.
