For Spartanburg, Zillow’s current ZHVI puts the typical city home value at $236,519.95, while ZORI puts typical observed market rent at $1,375.44 per month. That pairing implies a 6.98% gross yield before maintenance, management, vacancy, insurance, taxes, utilities, capital work and financing. As affordability screens, the Zillow value is 4.55x ACS median household income, and annual Zillow rent equals 31.76% of that income; these cross-source ratios do not describe any specific buyer or tenant.
The city has 17,458 housing units, with an ACS vacancy rate of 8.79%; renters occupy 46.14% of occupied units. ACS reports a $203,700 median home value and $1,099 median gross rent for surveyed occupied housing, with gross rent including selected utilities. Those ACS medians differ in concept and period from Zillow’s typical home value and observed market rent, so they should remain separate rather than be averaged or treated as matching transaction and lease quotes.
City ACS depth shows 54.63% of renter households are rent-burdened. The housing stock is 66.46% single-family and 7.96% large multifamily, while units vacant for rent represent 14.47% of all vacant units. Population is 38,910, and the change between overlapping ACS five-year vintages was 3.97%; this is not annualized and could reflect boundary changes. Median household income is $51,964, with poverty at 23.81% and unemployment at 7.45%. These demand constraints are descriptive, not causal; stock and vacancy-reason shares neither identify purchasable inventory nor prove a particular rental will lease quickly.
At the county scope, Spartanburg County listings had a median 54 days on market and a 20.01% price-reduced share, indicating that property-specific negotiation may matter but not measuring city liquidity. In the broader Spartanburg, SC metro, housing supply was 3.8 months and metro jobs grew 0.73% annually; neither figure is city-specific. The national Freddie Mac 30-year mortgage rate was 6.58%, serving only as a national financing benchmark rather than a borrower quote.
The central underwriting gap is property-level net income: gross yield omits operating costs, turnover, concessions, repairs and debt service, while citywide tenure and vacancy cannot establish achievable rent or occupancy for one asset. Before deciding, verify the address’s condition, unit count, legal use, title, taxes, insurance and hazard exposure; obtain current lease and rent-roll evidence; inspect major systems; price immediate and recurring capital needs; compare truly similar local sale and rental listings; and test financing terms, reserves and cash flow under slower leasing and higher-cost scenarios.
