ZIP 45040 enters the latest June endpoint with Zillow’s ZORI at $2,086 per month. This is a ZIP-level typical observed asking-rent index blended across rental types, so it is a market signal rather than a quoted rent for a particular home. The index was up 1.9% on an exact same-month basis from the prior June. That positive reading establishes that the latest index is still rising, while the rate of increase, assessed against the longer record below, is the central tension. It should not be read as a lease offer, a utility-inclusive total, or evidence that every available property commands the index.
The full history points to cooling rather than a reversal. Exact same-month annualized gains were 1.9% over 1-year, 4.5% over 3-years and 6.1% over 5-years through June 2026; that first reading is therefore the actual June-to-June change, not a forecast. Recent direction confirms rent growth but breaks from the faster longer-run pace. Annualized monthly-return variability was 2.7%, and maximum drawdown was −1.6%; those limited measured movements support some confidence in the broad current index level but not in a particular property’s price. Coverage is 100% across 103 observations and 102 consecutive monthly returns. For transparent national discovery among history-eligible ZIPs, momentum ranks 1,005, stability ranks 974, and balanced rank 682, where lower ranks are higher. These are backward-looking measurements, not an investment recommendation or projection.
Zillow and Census figures describe different universes, which helps explain a sizable level gap. The matched Census ZCTA’s ACS 2024 five-year survey puts median gross rent at $1,811 among occupied renter homes; it includes selected utilities and is not a current asking-rent series. Against that survey measure, the $2,086 ZORI is $275, or 15.2%, higher. The ZCTA is a Census statistical area and is not identical to a USPS delivery ZIP, even though this five-digit label is both the Zillow ZIP market identifier and the Census ZCTA match. Neither series converts the other into a unit-specific rent: timing, sampled occupied homes, utility treatment, and the index’s blended rental types all remain material.
HUD supplies a separate administrative benchmark, not asking rent. Its FY2026 local bedroom-specific FMR ladder provides the scale for the ZORI-based estimates. Scaling the ZIP ZORI by that local HUD ladder produces modelled monthly estimates of $1,480 for a studio, $1,624 for one bedroom, $2,086 for two bedrooms, $2,754 for three bedrooms, and $3,042 for four bedrooms. These are modelled estimates, never measured bedroom rents, and the HUD FMR/SAFMR values are administrative standards rather than observed listings. The alignment of the two-bedroom model with the overall index is a scaling result, not proof that a typical two-bedroom is available at that amount.
An arithmetic 30% screen places annual income needed to cover twelve months of the current index at $83,440. That compares with the ZCTA’s ACS median household income of $133,240, and the index annualized is 18.8% of that median. The calculation is not advice and not an applicant qualification rule: it omits taxes, debts, household composition, utility treatment, deposits, and a property’s actual lease price. Within the ACS renter universe, 1,209 of 4,907 renter households, or 24.6%, report gross-rent burden at or above the threshold. That burden statistic describes surveyed renter households and cannot establish the burden, availability, or suitability of any particular apartment or house.
Supply evidence contextualizes rather than resolves that rent premium. The ZCTA reports 22,719 housing units and 719 vacant units, a 3.2% vacancy rate, including 311 units vacant for rent; renters account for 22.3% of occupied homes, while single-family units make up most of the stock. As wider context only, Mason city context rent is $2,097, Warren County context rent is $1,949, and Cincinnati, OH-KY-IN metro context rent is $1,583. Thus the ZIP index sits essentially at the city context level but above the county and metro context levels; these wider-area figures are comparisons, not substitutes for a ZIP listing measure. Vacancy counts do not identify the quality, bedroom count, rent, or immediate availability of a particular unit.
The remaining uncertainty is property-level and cannot be resolved by these aggregates. A listing review needs the advertised rent and concessions, confirmed bedroom count and square footage, lease term, move-in date, deposit and recurring fees, which utilities are included, and whether the address falls inside the market geography used by the index. It also needs a comparison of the asking price with contemporaneous available properties of similar configuration, rather than with the modelled ladder alone. The ZORI endpoint, ACS survey period, HUD fiscal-year standard, and wider-area contexts use different timing and definitions. Does the specific property’s verified all-in monthly cost and availability support the conclusion suggested by this broad ZIP snapshot?
