ZIP 33604 presents a current-rent versus income tension before any property-specific conclusion is drawn. Zillow ZORI was $1,588 in 2026-06; it is a typical observed asking-rent index blended across rental types, not a lease quote for a particular home. Wider context only: Tampa city’s context rent was $1,999, Hillsborough County’s context rent was $2,025, and the Tampa-St. Petersburg-Clearwater metro context rent was $2,020. The ZIP’s asking-rent-to-median-income screen was 32.4%. At a 30% rent-to-income arithmetic screen, that asking rent implies $63,520 of annual income, above the local median household income of $58,766. This is arithmetic rather than advice, and it is not an applicant qualification rule.
The recent rent direction breaks from the longer backward-looking path. Exact same-month ZORI change was -0.1% over one year, versus annualized gains of 1.6% over three years and 6.0% over five years. The history has complete 100% coverage across 138 observations, supporting the continuity of the measurement rather than a forecast. Annualized monthly-return variability was 3.2%, so a single current index reading deserves measured confidence rather than being treated as a fixed rent level. The maximum drawdown was 1.9%, indicating the largest peak-to-trough decline observed in this record. Transparent national discovery ranks among history-eligible ZIPs were 2,171 for momentum, 1,897 for stability, and 2,420 for the balanced measure, where lower ranks are stronger. These are descriptive discovery tools, not investment recommendations.
The five-digit label is both a Zillow ZIP market identifier and a match to a Census ZCTA. A ZCTA is a Census statistical area and is not identical to a USPS delivery ZIP. In the ACS 2024 five-year survey, occupied renter homes in the matched ZCTA had median gross rent of $1,412, with an $82 margin of error; this measure includes selected utilities and is not a current asking-rent measure. ZIP ZORI was 12.5% above that gross-rent median. The difference is informative about distinct evidence universes, including timing, occupied homes versus advertised supply, and utility treatment, rather than proof that any given unit is priced above or below its market.
Bedroom figures should be used as a modelled allocation of the ZIP index, not as measured bedroom rents. Scaling ZIP ZORI through the local HUD ladder produces modelled monthly estimates of $1,280 for a studio, $1,364 for one bedroom, $1,588 for two bedrooms, $2,029 for three bedrooms, and $2,469 for four bedrooms. The local HUD FMR/SAFMR two-bedroom standard is $1,910. HUD FMR/SAFMR is an administrative, bedroom-specific standard and not asking rent; it provides the ladder used in the model, not observed lease comparables. Actual advertised rents can differ with unit condition, included utilities, concessions, lease term, and property-specific features.
The matched ZCTA had 40,055 residents, 17,409 housing units, and 1,570 vacant units, a 9.0% vacancy rate. Renter occupancy totaled 6,969 households, representing a 44.0% renter share. Among those renter households, 4,269 were recorded as spending at least thirty percent of income on rent, or 61.3%. These ACS estimates describe surveyed occupied households over a multi-year period; they do not establish current availability, vacancy at a particular building, or the rent burden of a prospective tenant. Still, the burden share and the current income screen both make affordability an important counterweight to the ZIP’s longer rent-growth history.
The direct rolling-three-month Redfin ZIP resale observation is a separate for-sale-market record, not rental transaction evidence. Median sold price was $379,414, up 0.5% year over year, with 183 homes sold and a median 49 days on market. Reported inventory was 180 homes alongside 393 active listings, and months of supply stood at 3.0. Sale-to-list signals were less than full-price on average: the average sale-to-list ratio was 97.9%, while 13.5% of sales closed above list. This resale evidence modestly challenges a simple rent-strength reading: sales pricing edged upward while the latest asking-rent index was slightly lower year over year. Annualized ZIP ZORI divided by median sold price was 5.0%, a cross-source screening ratio only, not a cap rate, property yield, net return, or expected return.
Viewed together, the evidence does not form one unified housing-market measurement. Zillow measures a blended asking-rent index; ACS measures occupied renter households and gross rent with selected utilities; HUD sets administrative bedroom standards; and Redfin records ZIP resale outcomes. The city, county, and metro values are wider context, not substitutes for ZIP observations. The central tension is therefore clear but bounded: current asking-rent pressure against local income and reported renter burden sits beside a long historical expansion that has recently cooled, while resale pricing shows only a small positive annual change. None of these relationships identifies a cause or determines an outcome for a specific property.
Before applying these screens to a home, verify the address geography, the actual bedroom count, advertised rent, included utilities, concessions, lease duration, and whether the unit is presently available. Compare the property’s condition and asking terms with current directly relevant listings rather than treating the modelled bedroom ladder as a quote. For a resale candidate, review property-specific sale history, list-price changes, inspection-related condition, and carrying costs separately from the ZIP screening ratio. For a rental decision, confirm income definitions and tenant-specific expenses rather than inferring affordability from area medians. Which property-level documents would most materially change the interpretation of this ZIP-level evidence?
