2026 Market Update: Charleston
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 $1,385/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 $-903/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 4.8% vacancy rate position Charleston as a growth-dependent market. With annual appreciation at 4%, total returns (cash flow + equity growth) run approximately 7.9% before financing leverage.

Is Charleston a Good Place to Invest in Rental Property?
Charleston, SC has a population of 156,110 and has been growing at 2.2% annually — well above the national average, signaling strong housing demand from population inflows. The median home price of $430,000 paired with median rents of $1,970/mo produces an estimated cap rate of 3.86%.
Property taxes at 0.57% are well below the national average of ~1.1%, providing a meaningful cash flow advantage many investors overlook. The vacancy rate of 4.8% is impressively low, indicating tight rental supply and strong tenant demand — favorable for landlords.
At a price-to-income ratio of 6.3x, homes cost about 6.3 times the local median income of $68,400. This elevated ratio means homeownership is stretched, supporting rental demand but limiting buyer pools. Home values have appreciated at roughly 4% 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, 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.
