The current reading and the resale scale create the central tension in 29464. At the latest June observation, Zillow’s ZIP-level ZORI is $2,372 per month, 1.56% above a year earlier. ZORI is a typical observed asking-rent index blended across rental types, not a lease comp, a concession-adjusted quote, or the rent for one home. It describes an asking-rent market, whereas the resale evidence later in this report describes for-sale transactions. A modest current rent change therefore cannot be treated as a conclusion about one property’s economics. The five-digit label functions both as a Zillow ZIP market identifier and as a Census ZCTA match, but the relevant evidence universes remain separate.
Backward-looking ZORI history shows exact same-month annualized changes of 1.56% over 1 year, 2.65% over 3 years, and 6.89% over 5 years through June 2026. The positive recent direction confirms the longer upward path, but it breaks from that path’s faster pace rather than signaling acceleration. Coverage is 100%, so the history does not have a data-gap qualification. Annualized monthly-return variability is 3.13%, while maximum drawdown is 2.20%. Those measured movements mean a current rent snapshot merits moderate rather than absolute confidence: it is a point within a changing series. Transparent national discovery ranks are 1,476 for momentum, 1,818 for stability, and 1,797 for the balanced score. They measure historical placement among history-eligible ZIPs, not a forecast or investment recommendation.
Zillow’s asking index cannot be substituted for the ACS five-year survey. The matched ZCTA reports $2,081 median gross rent among occupied renter homes, and gross rent includes selected utilities. A ZCTA is a statistical area; even where it matches this Zillow market label, it is not identical to a USPS delivery ZIP. ACS is a retrospective survey of occupied renter homes, whereas ZORI reflects typical observed asking rent across rental types. The ZCTA rent estimate also has a published margin of error, underscoring that it is an estimate rather than a current advertised-price census. These measures answer different questions and should not be presented as competing observations of the same leases.
The bedroom ladder supplies a separate, modelled view. These are modelled estimates, never measured bedroom rents: $2,063 for a studio, $2,166 for one bedroom, $2,372 for two bedrooms, $2,953 for three bedrooms, and $3,403 for four bedrooms. Each estimate scales ZIP ZORI with the local HUD ladder. HUD FMR/SAFMR is an administrative bedroom-specific standard, not asking rent; its two-bedroom local standard is $2,530. Accordingly, the ladder is useful for a consistent bedroom pattern but does not establish a unit’s advertised rent, utilities, condition, availability, or program treatment. It also does not convert the blended ZORI into observed rents for each bedroom class.
Income and burden generate a second tension. The ZCTA median household income is $111,907, and annualized current ZORI equals 25.4% of that amount. The $94,880 required-income figure from the 30% screen is arithmetic, not advice and not an applicant qualification rule. Separately, 49.3% of surveyed renter households reported spending at least that income share on gross rent. That ACS burden measure is retrospective and population-level, with gross rent including selected utilities; it neither establishes affordability for a particular household nor proves the burden attached to a particular unit. The income screen and burden survey should consequently be read together, without treating either as a leasing decision.
The ACS stock profile supplies scale, not live availability. Of 27,269 housing units in the ZCTA, 3,306 were vacant, a 12.1% vacancy rate. The structure mix includes 18,585 single-family units and large multifamily structures, while 1,293 vacancies were classified for rent. These are survey-based category counts rather than a current availability feed, and they do not tell whether vacant-for-rent homes were priced near ZORI or suitable for a given household. Vacancy also includes different uses and timing; no vacancy statistic proves that any named property, unit type, or advertised unit is available.
Place context reinforces that this ZIP is not interchangeable with its wider geographies. In wider-context asking-rent data—not ZIP comparables—Mount Pleasant city is $2,425, Charleston County is $2,156, and the Charleston–North Charleston, SC metro is $2,066. The ZIP index thus sits below the city context yet above the county and metro contexts. These are geographic benchmarks with their own rental mixes, boundaries, and source aggregation, so they should not be used as citywide, countywide, or metrowide evidence about a ZIP unit. The comparison is descriptive: it identifies relative positioning, not a reason for the position or a prediction that the gaps will close.
Redfin’s direct rolling-three-month ZIP resale observation, rather than rental transactions, provides the liquidity counterpoint. Its median sold price was $999,774, 1.24% higher year over year, across 293 homes sold; median marketing time was 60 days. Resale inventory was 352 homes, up 20.0%, with 3.6 months of supply. The average sale-to-list ratio was 97.61%, and 10.89% of sales were above list. Those figures remain entirely in the for-sale universe. Both the modestly positive sale-price change and the positive ZORI change align in direction, yet growing inventory, time on market, and below-list average sales challenge any simple claim of uniformly tight conditions. Because sale price and monthly rent use different units and market universes, the rent-only income screen cannot be read as for-sale affordability. Annualized ZIP ZORI divided by median sold price is 2.85%, a cross-source screening ratio only—not a cap rate, net return, expected return, or property yield. Relevant property-level checks include active asking rent, bedroom count, utilities, lease term, concessions, availability, condition, and direct sale or rent comparables. Does the actual unit’s documented information fit the appropriate source universe?
