The distinctive question in 78660 is how to use a current blended asking-rent signal without mistaking it for a lease quote or a household-cost measure. In June 2026, the ZIP-level Zillow Observed Rent Index (ZORI) is $1,679 per month, down 2.39% year over year. It is a typical observed asking-rent index blended across rental types, so it offers a market-level reference rather than a bedroom-specific listing sample. The practical issue is whether source gaps reflect definitions and timing rather than a signal assignable to one property. The five-digit label 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, which matters when an address or property boundary is being checked.
The Zillow index should not be merged with either survey rent or a public standard. The matched Census ZCTA’s ACS 2024 five-year median gross rent is $1,863, a measure of occupied renter homes that includes selected utilities; the current index is 9.9% lower. ACS is a survey result, whereas ZORI is asking-rent evidence, and neither supplies the other’s unit mix or utility treatment. Separately, the FY 2026 HUD two-bedroom FMR/SAFMR is $1,852, placing the ZIP index 9.3% below that benchmark. HUD FMR/SAFMR is an administrative, bedroom-specific standard, not asking rent, so its proximity to either rent figure does not establish a quoted rent. The comparison is useful as separate reference points, but it is not a conversion between data sets.
Bedroom comparisons are best treated as an explicit model rather than as observations. The local HUD ladder scales the ZIP ZORI from its two-bedroom anchor, producing modelled monthly ZIP estimates of $1,336 for a studio, $1,416 for one bedroom, $1,679 for two bedrooms, $2,128 for three bedrooms, and $2,502 for four bedrooms. Each amount applies the relevant local HUD bedroom-to-two-bedroom ratio to the ZIP index. These are modelled estimates, never measured bedroom rents: they do not report advertised-unit samples, rent dispersion, utility inclusion, condition, availability, or the terms of any individual property. It shows relative bedroom sizing under the model, not a lease-level outcome.
The income and burden evidence addresses household context, but it does not make the ZIP index an affordability finding. The ACS ZCTA median household income is $113,205, and comparing annualized ZORI with that household median yields a 17.8% asking-rent-to-income ratio. The $67,160 income associated with paying $1,679 monthly at 30% of gross income is arithmetic only, not advice or an applicant qualification rule. Renter households number 15,462 and represent a 33.9% renter share. ACS also records 7,401 renter households reporting gross rent at or above 30% of income, or 47.9% of its renter burden denominator. That observed burden is a survey-wide household measure, not proof of the cost or finances of a particular unit or tenant. It also does not identify the income distribution among renters.
The matched ZCTA’s ACS housing inventory contains 47,531 units: 45,630 are occupied and 1,901 are vacant, for a 4.0% all-housing vacancy rate. Within the reported vacant inventory, 473 units are for rent, 451 are for sale, and 82 are seasonal; those named statuses are components, not a current count of marketable rental listings. Single-family structures account for 34,991 units, while large multifamily structures account for 4,704 units, describing stock categories rather than tenure or lease availability. The timing and classification of a vacancy cannot demonstrate that any particular dwelling is available, rentable, similarly priced, or suitable for a given household.
Wider geography is context only, not a substitute for ZIP or ZCTA evidence. The city of Pflugerville context reports rent of about $1,699; the Travis County context reports rent of $1,649 and a 47.9% renter share; and the Austin-Round Rock-Georgetown, TX metro context reports rent of $1,653, a 19.75% rent-to-income measure, and 9.53% apartment vacancy. The ZIP’s current $1,679 index therefore sits between the county and city context rent figures and slightly above the metro context rent figure. Differences in geographic scope and metric construction are material before treating small gaps as a market conclusion. The metro vacancy measure applies to apartments, unlike the ZIP’s all-housing vacancy rate, so those rates should not be read as the same evidence universe.
Important limits remain: the index, survey, and HUD standard have different collection rules, reference periods, and intended uses; ACS values also carry survey uncertainty. None reports a property’s exact asking price, bedroom layout, utility bill, lease term, concessions, fees, condition, or present availability. A property-level review should therefore confirm the address’s ZIP/ZCTA treatment, the current advertised base rent, bedroom count, lease length, included utilities, recurring and move-in charges, concessions, available date, and the property’s stated application requirements. Those checks preserve the distinction between a market index, gross-rent survey evidence, and an administrative standard while avoiding a conclusion about a specific listing.
