ZIP 78727 presents a cross-market cooling tension rather than a single rent conclusion. The latest Zillow ZORI is $1,514 per month, a ZIP-level typical observed asking-rent index blended across rental types. That current asking-rent signal belongs to rentals, while the for-sale evidence described later is a separate resale observation. The central reading is therefore not that one series values the other, but that both should be tested for consistency: a softer current rent snapshot can coexist with a slower or repriced sale market. The annualized ZORI-to-price figure is only a screening ratio, not an operating result.
Same-month rent history supports a cooling interpretation. ZORI declined 2.0% over one year and fell at a 3.4% annualized rate over three years, while the five-year annualized change remained positive at 0.8%. Recent direction therefore confirms the intermediate decline but breaks from the modest longer-run gain. Annualized monthly-return variability measured 3.1%, indicating that month-to-month changes have not been exceptionally erratic, yet the historical maximum drawdown reached 11.9%, which limits confidence in treating one current rent reading as a durable level. The record contains 126 observations with 100% coverage. Among history-eligible ZIPs, transparent national discovery ranks were 2,831 for momentum, 1,837 for stability, and 2,746 for the balanced measure; lower ranks indicate higher placement. These are backward-looking measurements, not forecasts or investment recommendations.
The five-digit label 78727 is both a Zillow ZIP market identifier and the matched Census ZCTA; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. The ACS 2024 five-year survey reports a median gross rent of $1,882 with a $45 margin of error. That survey covers occupied renter homes and includes selected utilities, so it is not interchangeable with Zillow asking rent. The local HUD FY 2026 two-bedroom FMR/SAFMR standard is $1,852; HUD is an administrative, bedroom-specific standard rather than asking rent. In wider context, the Austin city context asking-rent figure is $1,615, the Travis County context figure is $1,649, and the Austin-Round Rock-Georgetown, TX metro context figure is $1,653. Those are wider-geography comparisons only, not substitutes for ZIP evidence.
Bedroom sizing should be read as a modelling exercise rather than as a set of observed listings. Scaling the ZIP ZORI through the local HUD bedroom ladder produces modelled monthly estimates of $1,205 for a studio, $1,277 for one bedroom, $1,514 for two bedrooms, $1,919 for three bedrooms, and $2,256 for four bedrooms. These are modelled estimates, never measured bedroom rents. Their purpose is to translate the ZIP-wide blended asking-rent index into a consistent bedroom ladder while retaining the local HUD relative structure. They cannot establish what a particular building, lease term, condition level, or utility arrangement will command.
The income screen is comparatively favorable at the area-wide level but does not erase household-level burden. The ZCTA-wide median household income is $110,379. At the current ZORI, the arithmetic income required for annual rent to equal 30% of gross income is $60,560, and annualized asking rent equals 16.5% of that area-wide median income. This 30% screen is arithmetic, not advice and not an applicant qualification rule. ACS identifies 2,963 renter households paying at least 30% of income toward rent, equal to 36.1% of the surveyed renter population. That burden result is a survey measure across occupied renter homes; it is not proof that any particular unit is affordable or unaffordable.
Housing composition supplies useful context for that burden and rent reading without showing present-day availability. The matched ZCTA has 15,077 housing units, including 8,210 renter-occupied homes, for a renter share of 57.8%. Its overall vacancy rate is 5.8%, and 545 vacant homes were classified as for rent in the ACS tabulation. The stock includes both single-family and large multifamily structures, so a ZIP-wide index blends potentially different rental settings. Neither the vacancy rate nor the vacant-for-rent count demonstrates that a specific home is actively marketed, habitable, competitively priced, or available on a reader's move date.
The direct rolling three-month ZIP resale observation shows a separate form of cooling. Median sold price was $449,898, down 13.0% from a year earlier. There were 76 homes sold, median marketing time was 43 days, active listings totaled 178, reported inventory was 100 homes, and months of supply stood at 4.0. The average sale-to-list ratio was 98.1%; 18.9% of sales closed above list, while 41.4% of listings went off market within two weeks. These are for-sale market signals, not rental transactions or rental comparables. Annualized ZIP ZORI divided by median sold price equals 4.0%, a cross-source screening ratio only. The price decline broadly confirms the rent history's cooling direction, while the sale-to-list and marketing signals caution against reducing resale conditions to that ratio alone.
Important limits remain. ZORI is an index rather than a property-specific lease quote; ACS is a multi-year survey; HUD is an administrative standard; and Redfin records resale activity rather than rental economics. No series here establishes utilities, concessions, square footage, condition, tenant turnover, financing, taxes, insurance, repairs, or actual operating income. A property-level review should compare live same-bedroom asking rents, lease concessions and utility responsibility, recent signed-rent evidence where available, days marketed, renewal exposure, physical condition, and direct sale comparables with matching property type. The useful final question is whether those checks support the current ZIP-level signals, rather than whether any single source can answer every rent or resale question.
