In Apex, ZIP 27502 presents a split screen: Zillow’s typical observed asking-rent index, blended across rental types, was $2,126 in June 2026, up 0.5% from a year earlier. Yet Redfin’s direct rolling-three-month ZIP resale observation shows a $599,864 median sold price, down 1.7% year over year, alongside inventory of 228 homes, up 36.5%. Rent movement is still positive while resale pricing and available for-sale inventory point to a less taut sales backdrop. That is a cross-market tension, not evidence that rental transactions and home sales are moving together or that either series predicts the other.
The Zillow history supports stable growth rather than a recent break from the longer path. Exact same-month annualized ZORI change was 0.5% over one year, 0.8% over three years, and 3.8% over five years: the current pace is slower, but still directionally consistent with the longer positive record. Monthly rent changes produced 2.6% annualized variability, so a single current rent reading warrants moderate rather than absolute confidence. The deepest historical decline from a prior peak was 2.6%, a limited retreat in the observed record. Coverage was 99.3%; transparent national discovery ranks among history-eligible ZIPs were 2,176 for momentum, 901 for stability, and 1,805 for the balanced measure, where lower ranks are higher.
These sources answer different questions. Zillow ZORI is a ZIP-level asking-rent index, whereas the matched Census ZCTA’s ACS five-year survey reports a $1,909 median gross rent for occupied renter homes and includes selected utilities; the asking index is therefore 11.4% above that survey median. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP. HUD’s FY2026 two-bedroom FMR/SAFMR standard is $2,140, putting the ZIP asking-rent index close to that administrative benchmark. HUD FMR/SAFMR is bedroom-specific program administration, not observed asking rent, and ACS gross rent is not a current asking-rent quote.
The bedroom view is a modelled estimate, created by scaling ZIP ZORI with the local HUD ladder; it is never a measurement of bedroom-specific rents. The resulting monthly estimates are $1,848 for a studio, $1,937 for one bedroom, $2,126 for two bedrooms, $2,672 for three bedrooms, and $3,567 for four bedrooms. This ladder is useful for comparing relative bedroom sizing within the ZIP’s index framework, but it does not capture the particular building, lease term, utilities, concessions, condition, or availability behind any advertised unit. Its alignment to HUD scaling does not turn the estimates into market observations.
At a 30% rent-to-income screen, annualizing the current ZIP asking-rent index produces required income of $85,040. That arithmetic threshold is below the matched ZCTA’s $143,922 median household income, and the index equals 17.7% of that area-level income measure. It is not advice, an applicant qualification rule, or evidence of what any household can pay. The ACS burden result introduces an important distributional counterpoint: among 3,204 renter households surveyed, 1,456, or 45.4%, paid 30% or more of income toward gross rent. That burden measure includes occupied renter homes and cannot establish affordability for a particular unit or renter.
The matched ZCTA’s housing profile also argues against treating a headline rent figure as a complete availability signal. Of 18,190 housing units, 17,368 were occupied, producing a 4.5% vacancy rate; 479 vacant units were classified as for rent. Renter households represented 18.4% of occupied homes. The stock was weighted toward 16,096 single-family units, while 780 units were in larger multifamily structures. These ACS five-year counts describe the surveyed housing base rather than live listings. In particular, vacant-for-rent units do not prove that a given property is currently rentable, offered at the index level, or suitable for a specific household.
Wider-area comparisons place the ZIP’s asking-rent index above the Apex city context rent of $2,017, the Wake County context rent of $1,676, and the Raleigh-Cary, NC metro context rent of $1,689; city, county, and metro figures are context only, not substitutes for ZIP evidence. The ZIP resale record adds direct liquidity detail: 262 homes sold with a median 28 days on market and 2.6 months of supply. Average sale-to-list was 99.14%, 21.2% of sales closed above list, and 46.4% went off market within two weeks. Those sales signals show ongoing transaction activity despite softer median price and higher inventory, challenging any simple conclusion drawn solely from the steadier rent history or the income screen.
The practical limits are substantial. ZORI is a blended asking-rent index, ACS is a lagged five-year survey with sampling uncertainty, HUD is an administrative standard, and Redfin measures for-sale resales rather than rental economics. Annualized ZIP ZORI divided by median sold price is only a cross-source screening ratio; it is not a cap rate, net return, expected return, or property yield. Property-level applicability depends on checks of the actual bedroom count, advertised rent, lease length, included utilities, concessions, occupancy status, condition, days available, sale comparability, and the distinction between an active listing and a completed sale. Those checks determine whether the broad ZIP evidence fits a specific property.
