OUR INTERPRETATION

San Francisco Real Estate Company Perspective

Our analytical view · Not a valuation or forecast

Local context checked . Market figures use the report period above. Local sources do not measure an amenity’s effect on prices or rents.

Castro’s thin cohort is a prompt to inspect the sales mix.

Local evidence: The Redfin transaction median is up 77.1% year over year. Price per square foot is up 17.3% year over year. The snapshot reports 14 median days on market. The sale-to-list ratio is 116.6%. These are All Home Types figures; the competition score has its own window.

Our view: The large change in the transaction median should not set the budget for an individual flat. We would separate houses, condos and TICs and review comparable condition, legal area and parking before making an offer. The price-per-foot change is much smaller than the median-price change, another reason to investigate which homes closed. Hold repair and appraisal-gap reserves outside the down payment rather than equate a strong market with guaranteed loan support.

Castro Station access begins at the building entrance.

Local evidence: SFMTA publishes the Castro Station stop page, while the library lists Eureka Valley/Harvey Milk Memorial at 1 Jose Sarria Court. These are destinations to test from the property, not measured commute or rental-premium data.

Our view: A direct route to the correct station entrance can matter more than a short map distance. Test grades, crossings and the return at the times you travel, then compare that routine with the cost of a garage. For a rental, verify achieved rents for similar apartments rather than assume that subway access alone pays for additional acquisition debt.

Price the Castro ownership documents before the neighborhood premium.

Local evidence: Frances lists 3870 17th Street and The Detour lists 2200 Market Street. Duboce Park is a nearby Duboce Triangle destination, not evidence that a property includes private open space.

Our view: We would distinguish enjoyment of the commercial corridor and nearby park from the building’s financial obligations. Request HOA or TIC records, insurance, planned roof and exterior work, and the legal parking and storage allocation. For an income property, compare current leases and net operating income after vacancy, management and a realistic capital reserve; test a flat-price exit after sale costs.

A SECOND LENS

Closed sales and modeled values tell different stories.

Zillow Castro typical home value (ZHVI)
$1,766,281

+20.4% year over year

Zillow data through September 2026. Its modeled value index differs from a median of homes that sold. Neighborhood boundaries, property coverage, and methods also differ. We do not average the two sources or treat their difference as a discount.

Build a Castro tour around the station, not just the listing.

Castro Station, 17th Street dining and the nearby Duboce Park offer different daily destinations. Walk the route from each candidate property rather than treating the neighborhood name as a commute time. Observe the entrance, stairs, grade and interior sound during the hours you expect to be home.

Separate the flat, the condo and the whole building.

A period facade does not reveal ownership or operating cost. Compare a condominium with its HOA budget, a TIC with its agreement and financing, and a whole building with its leases and capital needs. Treat outdoor space, parking and storage as rights to verify rather than features implied by a photograph.

A small sales cohort needs narrower comparables.

The Redfin page displays only five September sales and a large median-price change. That is a reason to inspect the mix of transactions, not assume every Castro home gained the same percentage. Match closed sales by legal size, ownership, condition and access before choosing an offer ceiling.

Research the neighborhood from the source.

WEATHER & EVERYDAY LIVING

San Francisco weather context.

Put Castro visits in context with city rainfall and regional sky conditions. Check the actual home in morning and afternoon light.

Rainfall and temperatures come from NOAA’s San Francisco Downtown station. Fog and sky conditions come from SFO and are regional context only. Neither station measures the featured neighborhood’s block-by-block microclimate; airport fog days are not neighborhood fog days.

Sources, definitions and limits +
  • Rainfall and temperature source: NOAA NCEI San Francisco Downtown, USW00023272 ↗, at 37.7705, −122.4269. These are city station readings, not measurements at an individual home. We sum the daily precipitation records and count days with at least 0.01 inches. The precipitation variable includes any liquid-equivalent frozen precipitation.
  • Daily values retain NOAA’s station observation dates. An observation day can end at a station’s reporting time; we do not relabel it as a midnight-to-midnight Pacific measurement. Trace precipitation is marked “Trace.” Missing or quality-flagged precipitation rejects a monthly update; incomplete temperatures remain unavailable.
  • Fog and sky source: National Weather Service CLMSFO, archived by Iowa Environmental Mesonet ↗. The source’s fog, fair, partly cloudy and cloudy counts are kept as reported. Fog can occur during part of a fair-weather day, so fog is not an additional mutually exclusive sky category. We do not convert fair days to measured sunshine hours or add them to fog counts.
  • These are free public weather records. Our summary and chart are independent of NOAA and Iowa State University. No affiliation or endorsement is implied. NOAA usage information ↗ · IEM usage information ↗.
  • Weather periods and source timestamps are separate from the rolling Redfin market window. Monthly updates retain the previous verified month if either source is delayed. These stations cannot establish a specific home’s sunlight, fog, moisture condition or investment return.

Sources, timing, and what to watch.

Redfin neighborhood metrics use rolling three-month windows. Adjacent periods overlap. Small samples and the mix of properties sold can move medians sharply. All home types is not a condo-only or multifamily investment series. The competition score uses its own stated window.

Refresh policy: the day after Redfin’s monthly Housing Market Tracker release, once a newer neighborhood period is verified. Source delays retain the previous report. An unavailable release timestamp is left blank; the calendar is not evidence that a neighborhood has updated.

Initial trend comparisons use the reported year-over-year change to derive approximate prior-year endpoints, not a downloaded monthly history. Verified monthly snapshots accumulate over time. Source revisions can change a previously reported figure.
