House hacking in San José (Berryessa / North SJ / River Oaks).

What's actually happening in 95131

• Existing anchors

  North San José tech corridor in-ZIP: Cisco (a large campus), Broadcom by the River Oaks station, Samsung, and Zoom. A real ZIP-level employment anchor rather than borrowed metro evidence. VTA River Oaks Station

• Operational

  River Oaks VTA light-rail station in-ZIP (Blue and Green lines, First St median), operational, plus the Berryessa/North SJ BART station on the north edge: a one-seat BART ride to Milpitas, Fremont, Oakland, and SF. VTA

• Adopted

  The Berryessa BART Urban Village reaches the ZIP's north edge (5,000+ homes, 25% affordable, ~25,000 riders/day by 2030). City of San José

• In rework

  HERO / North SJ Affordable Housing Overlay (Program P-3): the North SJ Area Development Policy was retired 5/17/2022 and is being reworked toward housing (3,095 units reallocated citywide), re-opening multifamily entitlement in a former jobs-only zone. County General Plan / San José Housing Element

• Existing anchor

  NVIDIA HQ ~4–6 mi northwest, hiring hard: ~42,000 employees Jan 2026, up 16.7% YoY. A renter-demand engine. NVIDIA newsroom

The numbers

Median price

~$1,476,250 (2026)

Market rent

3bd ~$4,300/mo (metro by-bed read, confirm per parcel)

Property tax (Santa Clara County)

1.44% median effective (per-ZIP read, 2026-07-10; verify the TRA per parcel)

Per-bed rent band

$1,250–1,600/mo per bed

ADU rent band

1bd $2,300–2,700, 2bd detached $2,700–3,100/mo

Whole-home rent band

$4,100–4,400/mo whole-home (3bd)

Underwriting vacancy

3.5–4% underwriting vacancy

Appreciation scenarios

3.0 / 4.5 / 6.0 %/yr (conservative / base / upside)

Jobs-anchored and tight; vacancy runs 3.5–4%. Appreciation basis: Operational BART and LRT with in-ZIP jobs; NVIDIA and North SJ demand plus the UV reach carry the base; the HERO overlay and Phase II are upside. Rent bands are city-level medians; confirm the specific parcel before trusting any of them. Run your own scenario in the calculator.

The house-hack angle

SB-9 or ADU on the Berryessa SFH lots, or a River Oaks townhome or condo run with roommates, but verify HOA rental limits first on River Oaks attached product. The renter pool is in-ZIP tech workers who want a walk or bike commute.

What breaks it

• Priciest-tier entry compresses the spread
• River Oaks HOAs may cap rentals or roommates: verify before committing to a by-unit or roommate lane
• Much of the North SJ frontage is industrial; desirability is parcel-specific
