At June 2026, Zillow’s ZIP-level ZORI stood at $1,679 per month, a 4.87% increase from the same month a year earlier. Redfin’s direct rolling-three-month ZIP resale observation reported a $299,932 median sold price, up 12.33% year over year. Annualizing ZORI and dividing it by that sold-price median produces a 6.72% cross-source screening ratio. It is only a limited cross-source screen, not an estimate of property-level financial performance. The resale price gain outpaced the latest asking-rent advance. That confirms upward movement in separate indicators, but challenges any claim that their pace, property sample, or unit economics is shared.
The five-digit label 29201 is both a Zillow ZIP market identifier and a Census ZCTA match. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP, so its boundaries and address use should not be assumed to coincide. Zillow ZORI is a typical observed asking-rent index blended across rental types. In contrast, the ACS 2024 five-year matched-ZCTA estimate is a survey of occupied renter homes: median gross rent was $1,174 and includes selected utilities. The current asking index sits 43.0% above that survey median. This difference reflects source universe, timing, covered homes, and utility treatment—not evidence that identical apartments underwent a change of that size.
History puts the current lift into a slower, still-positive path. Through the stated history endpoint, exact same-month ZORI changes annualized at 4.87% over 1 year, 5.50% over 3 years, and 6.79% over 5 years. Recent direction therefore confirms the longer upward path but not its faster earlier pace. The series has complete coverage. At 3.12%, the annualized dispersion of monthly returns indicates relatively contained index fluctuation. The maximum drawdown was -2.92%, a distinct peak-to-trough measurement rather than another form of volatility. These measures make the historical description more informative than a standalone current snapshot, though they remain backward-looking measurements rather than forecasts or investment recommendations. Transparent national discovery ranks among history-eligible ZIPs were 297 for momentum, 1,811 for stability, and 565 for the balanced measure; a lower rank is higher.
Resale liquidity provides a different tension. In Redfin’s direct rolling-three-month ZIP for-sale observation, 73 homes sold, median marketing time was 27 days, and inventory was 60 homes, with 2.5 months of supply. Average sale-to-list was 98.22%, a signal that belongs only to the for-sale universe. These are not rental transactions, rental comparables, or evidence of a particular owner’s leasing pace. The comparatively firm resale reading is consistent with the reported sale-price rise and positive rent history, yet it cannot resolve the ZCTA’s rent-to-income and vacancy readings. Different property mixes, transaction types, and timing leave the rent/resale screening tension intact.
Wider-area figures reinforce that the ZIP index should be read locally, not by substitution. The City of Columbia rent context, a city-scope value, was $1,478.17; the Richland County rent context, a county-scope value, was $1,502; and the Columbia, SC metro rent context, a metro-scope value, was $1,555. Each is below ZIP ZORI, but each is context rather than an alternative ZIP estimate. The City of Columbia context showed a more moderate rental concentration and vacancy profile than the ZIP survey. County and metro measures should similarly frame scale, not serve as ZIP rental comparables or direct evidence about an available address.
Housing composition amplifies that distinction. The ACS ZCTA survey counted 13,441 housing units, including a majority in large multifamily structures, and showed renter-dominant occupancy. Its 22.6% vacancy rate and vacant-for-rent component represent a stock setting distinct from a single listing. A vacant-for-rent count cannot establish that any particular apartment is immediately available, appropriately configured, competitively priced, or in comparable condition. Still, renter concentration alongside recorded vacant stock challenges a simplistic reading of rising ZORI as proof that every rental segment is uniformly tight.
The bedroom ladder is a scaling exercise, not a set of observed submarket rents. HUD’s FY2026 FMR/SAFMR ladder is an administrative, bedroom-specific standard rather than asking rent; its local two-bedroom standard is $1,276. Scaling the ZIP ZORI by each local HUD ladder rung creates modelled monthly estimates, in order from studio through four bedrooms, of $1,358, $1,532, $1,679, $2,136, and $2,515. These are modelled estimates, never measured bedroom rents. At 30%, the current ZORI implies $67,160 of required annual income; that is arithmetic, not advice or an applicant qualification rule. Against the ZCTA’s $32,297 median household income, it is a broad screen rather than a household outcome. ACS reports 61.8% of renter households as paying at least that threshold toward rent, a burden measure that does not determine any unit’s affordability.
The central limitation is comparability: a current asking-rent index, a five-year ZCTA survey, an administrative HUD standard, and a rolling resale observation answer different questions. The history describes past index behavior; neither it nor the rent-to-price screen predicts a lease outcome, a sale outcome, or investment performance. Address-level validation would require checking the advertised rent for the exact bedroom count, lease term, and included utilities; confirming actual availability, concessions, condition, and fees; and reviewing recent closed sales and listing terms for a resale comparison rather than importing ZIP medians. Which property-specific evidence is sufficient to reconcile advertised terms with this ZIP-level rent index and separate resale screen?
