ZIP 29212 has a decision tension between its rental index and resale direction. In Redfin’s direct rolling-three-month ZIP resale observation ending June 2026, the median sold price was $276,687, 5.08% below the prior-year reading. Zillow’s June ZIP ZORI, in contrast, was $1,620 per month. Annualizing the index and dividing it by that sold-price median produces a 7.03% cross-source screening ratio. It is not a cap rate, net return, expected return, property yield, or a statement of any home’s economics. The two series may coexist because one is an asking-rent index and the other describes for-sale transactions; the observed contrast is a signal to test, not a conclusion about any address.
Over the longer series, the rent index remains positive but its pace has slowed. Exact same-month ZORI changes annualize to 0.93% over one year, 2.14% over three years, and 5.20% over five years. Recent direction therefore confirms a positive longer path while breaking from the faster pace recorded over the longer windows. The backward-looking record has complete coverage over 113 monthly observations. Across the recorded monthly returns, variation annualizes to 3.56%; separately, the maximum peak-to-trough decline was 4.88%. This high-variability history reduces the confidence that belongs in one current rent snapshot. Transparent national discovery ranks are 1,760 for momentum, 2,285 for stability, and 2,341 for the balanced measure among history-eligible ZIPs, where lower ranks indicate higher relative results. They are descriptive ranks, not forecasts or investment recommendations.
Definitions control the rent comparison. The five-digit label is both the Zillow ZIP market identifier and a Census ZCTA match; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. Zillow ZORI is a typical observed asking-rent index blended across rental types. In the matched ACS 2024 five-year survey, median gross rent was $1,452 and includes selected utilities for occupied renter homes. The current asking-rent index is 11.6% higher, but that gap does not establish a quality difference, a lease quote, or a utility-adjusted price change. ACS is a five-year survey of occupied renter homes, while ZORI is an asking-rent index, so their timing, populations, and included costs differ.
The bedroom view is a modelled scale rather than a set of observed apartment rents. Scaling ZIP ZORI with the local HUD ladder produces modelled estimates of $1,310 for a studio, $1,478 for one bedroom, $1,620 for two bedrooms, $2,061 for three bedrooms, and $2,426 for four bedrooms. These are modelled estimates, never measured bedroom rents. The FY2026 local HUD two-bedroom FMR/SAFMR standard is $1,276, and the all-type ZORI is 127% of that standard. HUD FMR/SAFMR is an administrative, bedroom-specific standard rather than asking rent. Its role here is to supply a proportional bedroom ladder, not to verify the advertised rent, physical layout, or utility treatment of a specific dwelling.
Affordability has two distinct arithmetic screens. The matched ZCTA’s ACS median household income is $77,142. Applying a 30% rent-to-income screen to the current ZORI produces a required annual household income of $64,800; annualized ZORI equals 25.2% of the ZCTA median household income. This is arithmetic, not advice, a tenant budget, underwriting, or an applicant qualification rule, and the all-household income median is not a measure of prospective renter income. Within the ACS occupied-renter survey estimate, 1,807 of 4,062 renter households, or 44.5%, paid gross rent at or above 30% of income. Published ACS survey margins of error warrant caution, and the burden statistic cannot prove that any particular unit is affordable or unaffordable.
Housing stock provides scale, not an availability guarantee. The ACS ZCTA count includes 13,520 housing units, with 12,643 occupied and 877 vacant, for a 6.5% vacancy rate. Renters account for 32.1% of occupied households. The stock includes 9,754 single-family units and 1,109 units in large multifamily structures, indicating that the ZCTA’s reported housing base spans several structure types rather than a single rental format. Vacancy totals include different vacant-use categories, including units for rent, for sale, and seasonal use. Consequently, the overall vacancy figure does not show whether a given unit is currently offered, what its asking rent is, or whether its owner will accept a particular lease arrangement.
Wider-area levels provide scale context but must remain outside the ZIP conclusion: Columbia city scope had a contextual rent of about $1,478, Lexington County scope had $1,679, and Columbia, SC metro scope had $1,555. The ZIP’s current all-type asking-rent index is above the city and metro context figures but below the county context figure. These city, county, and metro values are wider-geography context only, not ZIP rental comparables or replacements for the matched ZCTA survey. They also cannot reconcile the source-universe differences between Zillow asking rents, ACS gross rents, and HUD administrative standards. The comparisons simply show where the ZIP’s index sits relative to the named surrounding scopes.
Read resale liquidity strictly within Redfin’s direct ZIP for-sale universe. The rolling observation reports 154 homes sold, a median 38 days on market, an inventory reading of 119 homes, and 2.3 months of supply. Average sale-to-list was 98.65%, while 18.68% of sales closed above list. These are resale signals, not rental transactions, and they do not establish tenant demand, collected rents, or operating costs. The lower year-over-year sold-price median and slightly below-list average challenge a simple reading of the positive rent history or the rent-price screen, but neither invalidates the other source. Property-level review can check the documented asking rent, bedroom configuration, utility responsibility, lease terms, availability, condition, and directly comparable recent sale and listing records. Does the specific address support the cross-source screen after those facts are verified?
