The sharpest measured tension in this ZIP is between a modest rent move and a much stronger resale-price move. Zillow’s typical observed asking-rent index was $2,147, up 0.77% from a year earlier, while Redfin’s ZIP median sold price was $727,336 after a 10.2% increase. Annualized ZIP ZORI divided by that sold price produces a 3.54% cross-source screening ratio. It is not a property yield, net return, cap rate, or expected return: it simply places an asking-rent index beside a resale median from another data universe. The resale-price increase is therefore not confirmation that rents have risen at a comparable pace or that household affordability has improved.
For June 2026, Zillow ZORI represents a ZIP-level typical observed asking-rent index blended across rental types, rather than a lease quote for a particular home. The matched ACS median gross rent was $1,759, making the current asking-rent index 22.1% higher; ACS is a five-year survey of occupied renter homes and includes selected utilities, so it is not asking-rent evidence. The five-digit label 92105 is both Zillow’s ZIP market identifier and a Census ZCTA match; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. At a 30% income screen, the index implies $85,880 in annual household income versus the ZCTA median household income of $68,563. The resulting 37.6% asking-rent-to-income relationship is arithmetic, not advice or an applicant qualification rule.
Backward-looking Zillow rent history shows a slowing path rather than a fresh acceleration. The exact same-month one-year change was 0.77%, compared with 1.86% annualized over three years and 5.34% annualized over five years. Thus, recent direction breaks from the stronger longer-run growth rate, even though it remains positive. Annualized monthly-return variability was 2.21%, which supports somewhat more confidence in a single current index reading than a highly erratic series would, but does not make that snapshot a lease-level fact. Maximum drawdown was 1.11%, separately indicating that observed declines were limited in this history. Coverage reached 99.1%; transparent national discovery ranks among history-eligible ZIPs were 1,873 for momentum, 299 for stability, and 1,051 for the balanced measure, where lower ranks are stronger. These are historical measurements, not forecasts or investment recommendations.
The bedroom ladder should be read as modelled estimates rather than measured bedroom rents. Scaling ZIP ZORI with the supplied local HUD ladder produces monthly modelled estimates of $1,635 for a studio, $1,758 for one bedroom, $2,147 for two bedrooms, $2,863 for three bedrooms, and $3,463 for four bedrooms. The local HUD FMR/SAFMR two-bedroom standard is $2,430. HUD FMR/SAFMR is an administrative, bedroom-specific standard rather than evidence of current asking rent, and the estimates inherit the broad rental-type mix of ZORI. A bedroom-specific listing can differ because its utilities, condition, furnishings, lease terms, and availability are not represented in the index or the modelled ladder.
The ACS housing profile places the affordability screen in a renter-majority statistical area. The matched ACS 2024 five-year ZCTA estimate shows 71,411 residents and 23,944 housing units, of which 22,910 were occupied and 1,034 were vacant. Renters occupied 67.4% of homes. Among renter households, 58.8%, or 9,073 surveyed renter homes, paid at least 30% of income toward gross rent. The overall vacancy rate was 4.3%, and 536 vacant units were classified as for rent. These figures describe survey-based area composition and vacancy categories, not the vacancy, tenant burden, or achievable rent of a specific building or unit.
Wider-area comparisons reinforce that the ZIP’s lower rent level does not automatically translate into a lighter burden screen. For wider context only, San Diego city’s Zillow asking-rent index was $3,038, San Diego County’s was $2,991, and the San Diego-Chula Vista-Carlsbad, CA metro’s was also $2,991; each is a broader geography than this ZIP. San Diego city’s ACS median gross rent was $2,313 and San Diego County’s was $2,246. The city renter share was 52.7% and the county renter share was 45.4%, both below the ZIP’s renter concentration. The metro’s rent-to-income context was 33.8%, below the ZIP’s arithmetic asking-rent-to-income relationship. These comparisons provide context only and should not be substituted for ZIP observations.
Redfin supplies direct rolling-three-month ZIP resale evidence, not rental transactions or rental comparables. In that for-sale universe, the median sold price and price change cited above came alongside 22 median days on market, 78 homes sold, 159 active listings, and inventory of 81 homes. Inventory was 18.6% higher than a year earlier, while months of supply stood at 3.1. The average sale-to-list ratio was 99.85%, and 51.4% of sales closed above list price. Together, those measures describe resale liquidity, marketing time, inventory, and sale-to-list outcomes. They challenge any simple reading that resale pricing and rents are moving together: the robust resale-price change contrasts with the slower one-year asking-rent result and the elevated burden screen, while not proving why either market moved.
Several limits matter before translating these area measures into a property decision. ZORI is an index rather than a unit quote; ACS results are survey estimates for occupied renter homes; HUD standards are administrative benchmarks; and Redfin tracks for-sale activity. The screening ratio also excludes operating costs, financing, taxes, insurance, maintenance, vacancy experience, and property-specific rent collection. Concrete property-level checks include current lease offerings by bedroom count, which utilities are paid by the tenant, concessions and lease duration, actual available-unit condition, and recent comparable sale and list-to-sale records for the specific property type. Those checks can test whether a listing resembles the broad ZIP measures without treating any area statistic as proof about one unit.
