The five-digit label 29730 is both Zillow's ZIP market identifier and the matched Census ZCTA label, but a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. In June 2026, Zillow's ZIP-level ZORI is $1,508 per month, up 5.3% year over year. The distinctive decision question is not whether every available home commands that amount: it is how this blended asking-rent benchmark should frame a search or pricing comparison when household resources, housing mix, and official standards describe different populations. The index establishes the current ZIP reference point, while later measures test affordability exposure, stock composition, and the meaning of comparisons without treating unlike datasets as interchangeable.
Household capacity gives the next decision lens. The ACS 2024 five-year ZCTA survey reports median household income of $68,543, while the 30% screen applied mechanically to the $1,508 monthly ZORI produces required income of $60,320. This is arithmetic, not advice and not an applicant-qualification rule. Renters occupy 39.7% of occupied homes. Among 9,681 renter households, 4,393, or 45.4%, report gross-rent burdens at or above 30%; the count's 90% ACS margin of error is 623, and the renter total's is 558. These are observed household-level survey conditions, not proof that any particular prospective tenancy is burdened.
Size-sensitive comparisons should use the local ladder carefully. Monthly modelled estimates are $1,308 for a studio, $1,378 for one bedroom, $1,508 for two bedrooms, $1,858 for three bedrooms, and $2,357 for four bedrooms. They are not measured bedroom rents. Instead, each modelled estimate scales the ZIP ZORI using the local FY2026 HUD ladder. HUD FMR/SAFMR is a bedroom-specific administrative standard, not asking rent. The estimates inherit the ladder's relative spacing rather than reporting an observed size-specific transaction or listing. They cannot reveal whether individual listings within the wider ZIP market at the time captured by the index share an identical lease structure, utility treatment, availability date, or condition.
Stock data adds a separate availability lens. The ZCTA contains 26,588 housing units, with 24,375 occupied and 2,213 vacant, yielding an 8.3% overall vacancy rate. Of all units, 17,996 are single-family and 2,510 are in larger multifamily structures. Within the vacant inventory, 538 are classified for rent, 105 for sale, and 60 for seasonal use. Those categories describe recorded vacant-unit status, rather than a real-time count of listings, lease-ready homes, concessions, condition, or price. Consequently, neither the overall rate nor the for-rent count establishes current available supply, availability, or terms for a particular unit. They also do not show how long a vacant unit has been marketed or whether it is currently available.
Source differences are material. Zillow's ZORI is a typical observed asking-rent index, blended across rental types, and its current $1,508 reading is 15.2% above the $1,309 ACS median gross rent. The ACS measure is a five-year survey of occupied renter homes and includes selected utilities, so it is neither a current advertised-rent series nor a unit-type match to ZORI; its median gross-rent margin of error is $58. HUD's FMR/SAFMR serves another purpose: it is an administrative bedroom-specific standard, not asking rent. Reading the three measures side by side can identify different reference frames, but cannot convert them into a single market price.
Broader figures offer context, not substitutes for ZIP evidence. In Rock Hill city context, the rent value is approximately $1,494, slightly below the ZIP index. In York County county context, the rent value is $1,645. In the Charlotte-Concord-Gastonia, NC-SC metro context, the rent value is $1,750. These city-, county-, and metro-scope figures differ in geography, so they establish comparison points rather than replacements for the ZIP index or the ZCTA survey. Scope differences limit direct substitution even when the directional contrast is clear. Neither context figure determines the rent, terms, or availability of any home inside the ZIP.
Limits matter at each step. ZORI summarizes typical observed asking rents rather than a matched inventory of units; ACS estimates are survey results with sampling uncertainty; HUD standards are administrative; and the bedroom series is modelled from the ZIP ZORI-HUD relationship. Geographic alignment also stops at the ZCTA match rather than recreating a USPS delivery boundary. For a specific property, the essential checks are the current advertised monthly rent, bedroom count, lease term, included or separately billed utilities, availability date, property condition, and whether the quoted home is actually offered at the stated terms. These checks preserve the distinction between market reference measures and a property-level transaction.
