The decision question in ZIP 28027 is not simply whether a quoted rent is high or low; it is which evidence universe can validly benchmark a current listing when bedroom size and included charges are not yet known. In June 2026, Zillow’s ZORI for this ZIP is $1,766 per month, up 1.28% year over year. ZORI is a typical observed asking-rent index blended across rental types, so it is a current ZIP-level pricing signal rather than a count of vacant units or a measure of any particular home. The label 28027 is both a Zillow ZIP market identifier and a Census ZCTA match. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP; that boundary distinction matters before attaching this benchmark to an address.
Source separation changes the reading of that figure. The matched ZCTA’s ACS 2024 five-year median gross rent is $1,561, with a $74 margin of error. It is $205, or 13.1%, below ZORI, but it does not establish that Zillow is over- or under-stating current listings. ACS is a five-year survey of occupied renter homes and its gross-rent measure includes selected utilities; it therefore describes a different population and cost concept from an asking-rent index. The FY2026 local HUD FMR/SAFMR ladder sets $1,660 for a two-bedroom. HUD is an administrative, bedroom-specific standard—not asking rent—and ZORI sits 6.4% above this rung only as a scale comparison, not as a market equivalence.
The bedroom view is useful only as an explicit model. The monthly ZIP estimates are $1,543 for a studio, $1,606 for one bedroom, $1,766 for two bedrooms, $2,170 for three bedrooms, and $2,766 for four bedrooms. They scale ZIP ZORI by the local HUD ladder relative to the local HUD two-bedroom point. That ladder runs from $1,450 for a studio to $2,600 for four bedrooms. Thus, the estimates preserve the local HUD size pattern while keeping the ZORI level; they are modelled estimates, never measured bedroom rents, and they do not show the rent, availability, or condition of a particular configuration.
Supply evidence adds a separate constraint to interpretation. The ZCTA has 32,419 housing units, comprising 29,238 occupied units and 3,181 vacant units, a reported 9.8% overall vacancy rate. The vacant total is heterogeneous: 821 units are classified for rent, 93 for sale, and 364 seasonal. It should not be read as a tally of units available today at the ZIP index or at a given bedroom model. The stock is also weighted toward 22,837 single-family units, compared with 2,579 units in large multifamily buildings. Those structure counts describe housing inventory, not rental listings, and provide no evidence about lease-ready status, turnover timing, or the price of an individual unit.
Household and burden data add an affordability screen but not a qualification test. The matched ACS ZCTA reports median household income of $92,219, with a $4,146 margin of error. Applying a 30% rent-to-income screen to the current monthly ZORI yields required annual income of $70,640; this is arithmetic, not advice or an applicant qualification rule. The annualized ZORI equals 23.0% of the broad household median, a comparison that cannot reveal the resources of a renter household or the costs attached to a specific lease. Renter households occupy 10,540 homes, representing 36.0% of occupied units. Within the ACS renter sample, 5,193 households reported gross-rent burden at or above that threshold, or 49.3%; the burden-count margin of error is 748 households. This is observed survey burden, not proof that a particular vacant unit is affordable or burdensome.
Broader geography provides context, not a substitute dataset. At the city scope, Concord’s current rent context is about $1,805; at the county scope, Cabarrus County’s current rent context is $1,829; and at the metro scope, Charlotte-Concord-Gastonia, NC-SC has a current rent context of $1,750. The ZIP index is lower than the city- and county-scope readings and higher than the metro-scope reading. Differences in boundaries, rental mixes, and source concepts mean that these wider city, county, and metro values cannot replace the ZIP ZORI, ZIP modelled bedroom estimates, or matched-ZCTA ACS observations.
Several limitations remain decisive at property level. ZORI is blended across rental types, the ACS ZCTA survey covers occupied renter homes over a multi-year period and includes selected utilities, and the local HUD ladder is a standard that may be ZIP SAFMR or county-derived; none identifies an actual listing’s rent. Before using these benchmarks, check the property’s exact address against the relevant ZIP and ZCTA boundary, current advertised rent and availability status, bedroom count, lease term, concessions, deposits and recurring fees, and which utilities are included. Also confirm the applicable HUD geography and bedroom rung. These checks prevent a vacancy category, survey burden rate, or modelled estimate from being misrepresented as a property-specific observation. The packet contains no forecast, causal explanation, or evidence of a particular unit’s condition or tenant outcome.
