How the Charleston cap rate is calculated
Cap rate is net operating income divided by price, where NOI is annual rent minus operating expenses and ignores the mortgage entirely. On theCharleston medians, NOI at a 40% expense load is:
NOI = $25,200 − $10,080 = $15,120
Cap rate = $15,120 ÷ $470,000 = 3.2%
A 40% expense load sits between the conservative 45% and the optimistic 35% used in the range above, which is why a single city number is always a band, not a point.
What the Charleston cap rate pays at different prices
The rent is the numerator and the price is the denominator, so a 10% move in price moves the yield in the opposite direction. Same median rent, three prices:
| Price point | Price | Gross yield | Est. cap rate |
|---|---|---|---|
| 10% below median | $423,000 | 6.0% | 3.3%–3.9% |
| At median | $470,000 | 5.4% | 2.9%–3.5% |
| 10% above median | $517,000 | 4.9% | 2.7%–3.2% |
Each row holds the rent fixed at the Charleston median, so the only variable is what you pay. That is the fastest way to see where a specific listing sits against its market.
