House hacking in Concord (Central / Monument / downtown BART).
The metro's single largest catalyst, the Concord Naval Weapons Station reuse, fronts an in-ZIP BART station in a $737K market: engineered growth at an entry-level basis.

The numbers
- Median price
- ~$737K (Movoto/HomeLight, May 2026)
- Market rent
- Concord $2,295/mo (flat YoY, Zumper, Jun 2026)
- Property tax (Contra Costa County)
- ~1.29% effective (Concord; JVM new-purchase 1.15–1.30%)
- Per-bed rent band
- $850–1,150/mo per bed
- ADU rent band
- $1,900–2,400/mo
- Whole-home rent band
- 2bd $2,300 / 3bd $2,800 whole-home
- Underwriting vacancy
- 5% underwriting vacancy
- Appreciation scenarios
- 1.5 / 3.0 / 4.5 %/yr (conservative / base / upside)
Contra Costa county median sale $760K, +2.6% YoY, 48-day DOM. Appreciation basis: CNWS counted as long-run tailwind only; 1950s–70s stock at mid capex, with the ADU rebate as an offset. 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
Best S-tier price-to-transit ratio in the metro. SFH-with-ADU and small multifamily near Monument Blvd; room-by-room to BART commuters and John Muir staff. The AFFH and ADU-rebate stack lowers the ADU-add cost.
What breaks it
- CNWS delivers over decades; the near-term thesis is BART plus hospital plus downtown infill, with CNWS as long-run tailwind
- Monument corridor tenant-income sensitivity
- Verify each downtown project's lease-up before crediting the pipeline
