ZIP 77381’s central reading is a current asking-rent index that stands well above its survey-based renter-housing benchmark. In June 2026, Zillow ZORI was $2,440 per month. This is a typical observed asking-rent index blended across rental types, rather than a recorded lease price for a specified dwelling. The five-digit label is both a Zillow ZIP market identifier and a matched Census ZCTA; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. For wider context only, Spring city-context rent was $1,750, Montgomery County context rent was $1,733, and the Houston-The Woodlands-Sugar Land, TX metro-context rent was $1,648. Those wider geographies are reference points, not replacements for ZIP-level evidence.
The backward rent path remains positive, but its speed has moderated from the longer run. Exact same-month annualized ZORI changes were 3.3% over one year, 3.6% over three years, and 8.0% over five years. Thus, the recent direction confirms the longer positive path but breaks from its faster five-year pace. Monthly ZORI returns annualize to 6.5% variability, meaning month-to-month movements have been material around the trend; separately, the worst peak-to-trough decline reached 7.3%. History coverage was 96.9%, supporting a substantial but not perfect record. Transparent national discovery ranks among history-eligible ZIPs were 785 for momentum, 2,893 for stability, and 1,881 for the balanced measure, where lower ranks are higher. These are backward-looking measurements, not forecasts or investment recommendations, and the high variability warrants less confidence in any single current rent snapshot than a smoother series would.
The source gap requires care before treating the current index as a household-cost measure. The matched ZCTA’s ACS five-year survey reports median gross rent of $1,727 with a $124 margin of error; it describes occupied renter homes and includes selected utilities. That gross-rent figure is 41.3% below Zillow’s current asking-rent index, but the difference is not an apples-to-apples market spread because the surveys and rent concepts differ. HUD FMR/SAFMR is instead an administrative, bedroom-specific standard, not asking rent; its local two-bedroom standard is $2,060. Scaling ZIP ZORI through that local HUD ladder produces modelled monthly estimates of $1,990 for a studio, $2,049 for one bedroom, $2,440 for two bedrooms, $3,281 for three bedrooms, and $4,098 for four bedrooms. These are modelled estimates, never measured bedroom rents.
The income screen is comparatively favorable at the ZIP-wide median, while the burden evidence remains a counterweight. Annualizing the current ZORI produces a $97,600 income requirement under a 30% screen. This is arithmetic only, not advice and not an applicant qualification rule. The matched ZCTA’s median household income was $143,565 with a $10,788 margin of error, placing the index-based asking-rent-to-income screen at 20.4%. Yet 49.7% of surveyed renter households paid at least 30% of income toward rent. That burden share exceeds the 39.1% shown in Spring city context and is slightly above the 47.5% in Montgomery County context. The figures indicate a difference between a ZIP-wide median-income arithmetic screen and the distribution of renter household circumstances; they do not establish affordability for any particular available unit or household.
Housing composition and vacancy add another constraint on broad interpretations. In the matched ZCTA, the vacancy rate was 3.8% and renters represented 21.4% of occupied homes. The structure mix was led by 12,306 single-family units, alongside 793 units in larger multifamily structures. There were 253 vacant homes classified as for rent. These counts and shares describe the area’s surveyed housing stock rather than a live inventory of comparable rentals, and they do not show unit condition, lease terms, concessions, bedroom count, or whether a listed vacancy is immediately available. A modest aggregate vacancy reading also cannot prove scarcity or pricing power for an individual property.
The direct rolling-three-month Redfin ZIP resale observation supplies a separate for-sale market signal. Median sold price was $617,360, up 2.47% year over year; 155 homes sold, with a median 18 days on market. Redfin reported 124 homes of inventory and 2.4 months of supply. The average sale-to-list ratio was 98.41%, while 22.54% of sales closed above list price. These are resale liquidity and pricing indicators, not rental transactions or rental comparables. Annualized ZIP ZORI divided by median sold price equals a 4.74% cross-source screening ratio only, not a property-level operating measure or return estimate. The positive resale price change and relatively short marketing time align directionally with the current positive rent reading, but the high resale-price denominator and renter-burden evidence challenge any simple reading of the area as uniformly affordable.
The most important limitations arise where source universes meet. Zillow is an asking-rent index, ACS is a multiyear survey of occupied renter homes, HUD is an administrative standard, and Redfin is a direct ZIP resale dataset. None substitutes for current unit-level evidence. A property review should verify the actual advertised rent, bedroom count, square footage, lease duration, utility responsibility, deposits, concessions, furnishing status, availability date, and any differences between the home and the rental types represented in the index. For a resale property, separately verify the address-specific condition and transaction terms rather than applying a ZIP median to a particular home. These checks are necessary because neither vacancy, burden, modelled bedroom estimates, nor resale liquidity proves the economics of one unit.
Overall, the evidence shows a ZIP with a high current asking-rent index relative to its ACS gross-rent benchmark, positive but less rapid recent rent history, meaningful historical variability, and a for-sale market whose resale measures remain distinct from rental evidence. Median-income arithmetic is less restrictive than the renter-burden share might suggest, making distributional differences more important than a single ZIP-wide affordability statistic. The useful next question is not whether the area has one definitive rent or value signal, but whether the specific unit’s lease structure and physical characteristics resemble the source universe being used for comparison.
