In June 2026, ZIP 40601’s Zillow Observed Rent Index (ZORI) is $1,151 per month, a typical observed asking-rent index blended across rental types. On an exact same-month basis, the one-year change is +1.9%; it remains positive but is materially slower than the annualized 5.1% three-year and 6.0% five-year changes. Recent direction therefore confirms the longer upward path in sign while breaking from its earlier pace. These are backward-looking measurements, not forecasts or investment recommendations. History has 100% coverage through the endpoint. Annualized monthly-return variability is 3.4%, and the maximum drawdown was a 2.1% decline; this high-variability history makes a current index snapshot less certain than a smoother series. Transparent national discovery ranks among history-eligible ZIPs are 940 for momentum, 2,177 for stability, and 1,543 for balanced performance, with lower ranks higher.
Zillow’s asking-rent index must remain separate from the ACS rent measure. In the matched Census ZCTA, the ACS 2024 five-year median gross rent is $966. The ACS measure is a five-year survey of occupied renter homes and includes selected utilities; it is not a current asking-rent series. By contrast, ZORI is a typical observed asking-rent index blended across rental types. The 19.2% spread is not a premium calculation because the measures use different universes and timing. The five-digit 40601 label is both the Zillow ZIP market identifier and the matched Census ZCTA label. A ZCTA is a Census statistical area and is not identical to a USPS delivery ZIP. The shared label supports this match, but neither series validates a particular listing.
An income screen makes the income-and-burden tension visible without treating area medians as household outcomes. Applying 30% of income to the index produces an annual required income of $46,040. That screen is arithmetic, not advice or an applicant qualification rule. The matched ZCTA’s median household income is $65,732, placing the annualized index amount at 21.0% of that all-household median. It is not renter-income data and cannot determine any applicant’s capacity. ACS counts 8,057 renter-occupied households, of which 3,278, or 40.7%, reported gross rent at or above the threshold. That aggregate burden result does not prove the burden of a particular unit.
As wider-scope context only, the City of Frankfort rental context is $1,151, the Franklin County rental context is also $1,151, and the Frankfort, KY metro rental context is $1,149. Their near alignment with the ZIP index indicates that these rounded area readings currently converge, not that their listings, households, or geographies are interchangeable. City, county, and metro values are wider-scope context only; they are not substitute ZIP-level observations or a basis for assigning a rent to an individual property. The comparison supplies a benchmark for scale, while the ZIP series remains the direct asking-rent evidence.
Bedroom labels require a different caution. Scaling the ZIP ZORI with the local HUD ladder produces modelled monthly estimates, not measured bedroom rents: $845 for a studio, $929 for a one-bedroom, $1,151 for a two-bedroom, $1,499 for a three-bedroom, and $1,785 for a four-bedroom. The HUD FY2026 FMR/SAFMR reference is an administrative, bedroom-specific standard, not asking rent. Its local two-bedroom standard is $1,090, below the corresponding modelled figure because the model preserves HUD ladder relationships while anchoring to ZORI. The ladder is a consistent scenario tool, not evidence that listings transact, ask, or are available at those bedroom values.
Matched ACS stock figures report 24,298 housing units, a 6.0% vacancy rate, and renters accounting for 35.3% of occupied homes. Single-family units outnumber large multifamily units in this stock. These figures describe the ZCTA aggregate rather than a property’s layout or tenure arrangement. A vacancy rate combines several vacancy categories; it cannot establish that a particular home is open, advertised, priced at the index, or suitable for a given household. The stock and vacancy evidence therefore identifies scale and composition, not the availability or condition of a specific rental.
Source limits should govern any property-level reading. Zillow does not provide a specific unit’s advertised rent or utility package; ACS does not describe a current listing; and HUD does not measure asking rent. A property-level check needs the live advertised rent, stated bedroom count, included utilities, lease term, availability date, and confirmation that the address falls within the relevant geographic boundary. It also needs timing aligned to the data comparison. Direct verification keeps each comparison tied to the item being evaluated rather than to an area aggregate. No index, survey, administrative standard, burden statistic, or vacancy statistic establishes the price, availability, terms, or household burden of a particular property.
