House hacking in San Francisco (Excelsior / Outer Mission / Ingleside).
The metro's cleanest transit-oriented affordability play: a large in-ZIP master build at a top-tier BART station, sitting on house-hack-friendly RH stock at a below-median entry price.
Status check: Verified 2026-07-14: Balboa Reservoir Phase 1A construction has been underway since Nov 2025, with Building A on for summer 2026. The synthesis-date WARN on those dates is resolved.
What's actually happening in 94112
- Phase 1A under construction
Balboa Reservoir: 1,100 units (550 BMR) adjacent to Balboa Park BART and City College; Building A (159 affordable units, up to 150 reserved for educators) starts construction summer 2026 for spring 2028 completion; Phase 1A infrastructure started Nov 2025 (dates WARN at synthesis). Balboa Reservoir project overview
- Operational

- Adopted

The numbers
- Median price
- $1,182,000 (Redfin/ATTOM, May 2026)
- Market rent
- ~$3,800/mo neighborhood median; 1-beds under $2,500 (RentCafe)
- Property tax (San Francisco County)
- 1.183% combined effective (SF Treasurer FY2025-26, consolidated city and county); new buyers pay about 1.183% of purchase price in year one, then assessed value rises at the 2%/yr Prop 13 cap until resale
- Per-bed rent band
- $1,200–1,700/mo per room
- ADU rent band
- $2,400–3,000/mo (ADU or in-law)
- Whole-home rent band
- $4,500–5,800/mo whole-home
- Underwriting vacancy
- 3.5–4.0% underwriting vacancy
- Appreciation scenarios
- 3 / 4–5 / 6 %/yr (conservative / base / upside)
More negotiable than the core. Appreciation basis: Balboa Reservoir delivering Building A in 2028 is the base; upside if the fourplex path and the Mission St FZP corridor confirm. 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
RH-1 and RH-2 stock reachable by the citywide fourplex exception (up to 4 units, 6 on corners); classic Excelsior single-family-with-in-law and 2-unit buildings; a City College, downtown-commuter, and immigrant-family tenant base.
What breaks it
- FZP reach into the Mission St and Geneva Ave corridors is unconfirmed (WARN): do not underwrite the upzone
- Older stock carries foundation and soft-story exposure
- Unpermitted in-laws are common here: verify the legalization path before crediting that rent
