If you want to live for free (or close to it) in San Francisco while building wealth — buying a multi-unit property might be the smartest move you can make.
Here’s how to buy a 2–4 unit building in SF, what it really costs, and why it’s one of the most powerful wealth-building moves in 2025.
🧱 What Qualifies as a Multi-Unit?
- Duplex: 2 units
- Triplex: 3 units
- Fourplex: 4 units
→ Anything 5+ units is commercial and has different loan rules
💰 Why Multi-Units Are Powerful in SF
- Live in one unit, rent the rest = offset your mortgage
- Leverage SF’s high rents for passive income
- Often come with under-market tenants = upside
- Unique chance to own income property and a primary residence
💸 Cost of a Multi-Unit in 2025
| Area | Typical Price (2–4 Unit) | 25% Down |
|---|---|---|
| Inner Richmond | $1.6M–$2.1M | $400K–$525K |
| Sunset | $1.4M–$1.9M | $350K–$475K |
| Bayview | $1.0M–$1.3M | $250K–$325K |
Rates for 2–4 units = ~6.75% (slightly higher than SFR/condo loans)
🧠 Christopher’s Strategy Tip:
“My first investment was a 4-plex in Inner Richmond. I live in one unit and the rent from the other 3 covers most of my mortgage. In a high-cost city like SF, it’s the smartest way to build equity while reducing your monthly burn.”
🔑 How to Buy a Multi-Unit in SF (Step-by-Step)
- Get Pre-Approved for multi-unit financing (Conventional or DSCR)
- Know Rent Control Rules — SF has strict laws on multi-units
- Target 2–4 Unit Inventory in neighborhoods w/ upside
- Analyze Rent Roll + Expenses
- Write Strategic Offers — consider seller credits + repair leverage
🧮 House Hack Example (Triplex in Outer Sunset)
- Purchase Price: $1.6M
- Down Payment (25%): $400K
- Monthly Rent (2 units): $6,000
- Monthly Mortgage (PITI): ~$8,800
- You live in 3rd unit = cost to live: ~$2,800/mo
→ Compare that to renting a similar unit in SF for $3,600+
