Charleston’s city decision frame starts with Zillow: a typical home value of $172,278 and typical observed monthly market rent of $1,370. Their pre-cost gross yield is 9.5%, before vacancy, management, maintenance, capital work, taxes, insurance, utilities and financing. ZHVI equals 2.6x ACS median household income, while annual ZORI equals 25.0% of that income. Faster observed rent growth than typical-value growth does not establish achievable rent or appreciation for a property.
The city’s housing stock skews toward owner occupancy: renters represent 36.7% of occupied units, while the citywide housing-unit vacancy rate is 17.3%. These are broad tenure and stock conditions, not immediate rental availability. ACS surveyed occupied housing reports a $203,300 median home value and $908 median gross rent, which includes selected utilities. The ACS measures differ in concept and period from Zillow’s typical value and observed market rent, so they should not be averaged or read as a pricing discrepancy.
Direct city depth is mixed. Among measured renter households, 46.8% spend 30% or more of income on rent. City housing units are 69.8% single-family and 11.1% large multifamily. Of vacant units, 25.6% are classified as for rent, a reason category rather than available investment inventory. Population declined 1.2% between overlapping ACS vintages; boundary changes may contribute, and the figure is not annual. Median household income is $65,812, with poverty at 15.8% and unemployment at 6.5%. These are demand constraints, not causal evidence about lease-up.
At the county scope, Kanawha County had a median listing time of 46 days and a 14.4% price-reduced share, useful for negotiation context but not city transaction timing. At the metro scope, the Charleston metro had 2.1 months of supply while payroll jobs declined 0.7% over the reported period; these metro measures pair listed supply with softer labor demand, not city outcomes. At the national scope, the Freddie Mac 30-year mortgage rate was 6.66%, a financing benchmark rather than Charleston borrower pricing.
Underwriting is limited by aggregate, mixed-period data: city Zillow metrics are not an appraisal, ACS survey shares do not identify rentable inventory, and wider county, metro and national context cannot be assigned to a building. Verify address-level sale and rent comparables, occupancy, lease terms, condition, deferred maintenance and capital needs. Obtain parcel taxes, insurance and hazard quotes, utility responsibility, management and turnover costs, zoning and title status, and lender terms; rebuild cash flow with realistic vacancy, concessions and repair reserves.
