643 38th St
Sold in April 1978 for $45,500 and never listed since — at 48 years, the second-longest recorded off-market stretch in this collection, a year behind 919 33rd St. Its Prop 13 assessment ($103,899 in 2025) keeps the tax bill at $2,833, while July 2026 valuation models cluster between $476K and $551K. Permit records show steady upkeep behind the scenes: a new roof and windows in 2014, and a new sewer lateral in 2017.

House notes
- Off market since April 1978 — the second-oldest recorded last sale in the collection, a year behind 919 33rd St (April 1977)
- Public records show two sales two months apart in 1978: $112,000 in February, then $45,500 in April — the February figure is far above what the neighborhood commanded in the 1970s and is likely a recording error
- The most recent recorded deed (March 2015) has no accompanying sale — a non-sale transfer, such as into a trust or between family members
- A Prop 13 time capsule: the 2025 assessed value of $103,899 is roughly a fifth of what valuation models put the house at, holding the annual tax bill to $2,833
- Recorded as Lot 26, Block 40 of the Spaulding/Richmond Pullman townsite
- Never listed on the modern MLS — no listing photos of it exist on any site; the only available exterior image is Street View
