At June 2026, Zillow’s ZIP-level asking-rent index for 38401 is $1,582 per month, a 0.26% year-over-year increase. The five-digit label is both Zillow’s ZIP market identifier and a matching Census ZCTA; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. The central tension is a current rent reading that is almost unchanged from a year earlier despite a stronger longer-run record. This is Zillow’s typical observed asking-rent index, blended across rental types, not a lease-specific quote or a count of every available listing. Against wider context only, the ZIP reading is near $1,580 in the Columbia city context, below $1,688 in the Maury County context, and below $1,810 in the Nashville-Davidson--Murfreesboro--Franklin, TN metro context. Those city, county, and metro figures describe wider geographies rather than this ZIP.
Same-month history through the stated endpoint shows annualized changes of 0.26% over 1 year, 0.81% over 3 years, and 4.29% over 5 years. The latest near-flat direction therefore breaks from, rather than confirms, the stronger upward path evident over longer windows; neither pattern is a forecast. Annualized monthly-return variability was 2.99%, maximum drawdown was -3.62%, and coverage was 98.86%. Those backward-looking measurements combine substantial coverage with some variation and a realized pullback, so a single current reading deserves less confidence than a multi-month pattern. Transparent national discovery ranks among history-eligible ZIPs were 2,249 for momentum, 1,616 for stability, and 2,321 for balanced performance, where a lower rank places higher. These discovery ranks organize past observations only and are not investment recommendations.
The matched Census ZCTA tells a separate, slower-moving story. Its ACS 2024 five-year survey estimates median gross rent of $1,187. This survey covers occupied renter homes and defines gross rent to include selected utilities; it is not a current asking-rent series and is not limited to homes being marketed. The Zillow index exceeds that survey median by $395, or 33.3%. That difference is a comparison of timing, coverage, and rent concepts, not proof that rents for any specific home rose by that amount. Keeping those universes separate is especially important when using the gap to frame a listing or a household budget.
Bedroom sizing adds a further model rather than a direct observation. These are modelled monthly estimates that scale the ZIP asking-rent index using the local FY2026 HUD bedroom ladder: $1,378 for a studio, $1,402 for one bedroom, $1,582 for two bedrooms, $1,989 for three bedrooms, and $2,421 for four bedrooms. HUD FMR/SAFMR is a bedroom-specific administrative standard, not asking rent, and the scaled figures are never measured bedroom rents. The ladder gives a consistent way to size the ZIP index, but it cannot identify actual asking rents for a property’s configuration, condition, utilities, lease terms, or availability.
One arithmetic screen underscores why the two rent concepts should not be blended. Holding the current monthly asking-rent index to 30% of gross income produces a $63,280 annual required-income screen, while the matched ZCTA’s ACS median household income is $68,475. The result is arithmetic, not advice and not an applicant qualification rule; all-household median income is also not the same universe as renter income. In the ACS renter survey, 45.3% of renter households pay 30% or more of income toward rent. That aggregate burden share is below 50.0% in the Columbia city context and 46.2% in the Maury County context, but it cannot establish affordability, income, or costs for a particular renter or unit.
The matched ZCTA’s housing stock has 29,161 housing units, including 22,178 single-family units. Its overall vacancy rate is 9.0%, and 820 units are classified as vacant for rent. These figures describe the survey’s stock and vacancy classifications, not a live inventory of currently tourable homes, and the rent-vacant count does not show price, bedroom size, condition, landlord terms, or whether a particular unit can be leased. Stock composition and vacancy can therefore supply market context, but neither proves that any specific listing is available or suitable.
Limits matter most where a reader moves from area measures to a property decision. Confirm the live advertised rent, whether the home remains available, the stated bedroom configuration and rental type, lease length, utility treatment, deposits, recurring fees, and all move-in charges. Match those facts to the source being used: Zillow is a blended asking-rent index, ACS is a five-year survey measure of occupied renter homes, and HUD is an administrative bedroom standard. Also verify how income is defined for the intended screen rather than treating a ZIP median or burden rate as a household result. With the recent index nearly flat but the longer record firmer, does the specific property’s live quote and terms fit the source-specific benchmark being considered?
