Fourplex Investing.
Generational wealth is created through physical assets. In the Bay Area, multi-unit properties allow you to offset expensive living costs, build tenant equity, and establish passive income streams.
Multi-Unit Residence • California Investing Options
Live in one unit. Rent the others.
House hacking is the practice of purchasing a 2-4 unit property, moving into one of the units as your primary owner-occupant residence, and renting out the remaining units to tenants. Read the full guide on house hacking.
This approach unlocks 1-to-4 unit residential finance benefits — allowing you to acquire a cash-flowing asset using FHA loans with as little as 3.5% down, rather than the hefty 20-25% down required for non-owner-occupied investments.
Use rental income from the other units to qualify with lenders!
What is house hacking and how does it work?
House hacking is purchasing a multi-unit property (2–4 units), living in one unit as your primary residence, and renting out the others. Because you occupy the property, FHA and conventional residential financing apply — meaning you can acquire an income-producing asset with as little as 3.5% down. The rent from your tenants offsets your mortgage, helping you build equity while someone else helps pay down your loan.
Can I buy a triplex or fourplex with an FHA loan?
Yes. FHA financing covers any residential property with up to four units, as long as you occupy one as your primary residence. The same 3.5% down payment requirement applies whether you are buying a duplex, triplex, or fourplex. Lenders will also consider projected rental income from the non-occupied units when calculating your qualifying ratios, which can significantly increase your purchasing power.
How do I calculate the return on a rental property?
The most common metric is capitalization rate (cap rate) — your net operating income divided by the purchase price. A 5% to 7.5% cap rate is generally considered healthy in East Bay markets like Richmond and San Pablo. Another useful metric is cash-on-cash return, which measures your annual pre-tax cash flow against the total cash you invested. Learn more about cap rates in the Bay Area. We walk you through every number so you can compare properties with confidence.

How We Analyze Investment Assets
Capitalization Rate
Net Operating Income (NOI) divided by the purchase price. We target 5% to 7.5% net yields in stable East Bay corridors.
Gross Rent Multiplier
Purchase price divided by gross annual rent. A simple gauge to compare sub-market values rapidly across Richmond & San Pablo.
Debt Service Coverage
Ensures monthly rental revenue exceeds the principal and interest debt payment. Vital for commercial & private investor lending templates.
CapEx & Vacancy Safety
Setting aside 5-10% of monthly rent for physical maintenance, tenant vacancies, and roofing reserves to guarantee stable cash flow.
Multi-Unit Purchasing Rules
1. Duplexes (2 Units)
The lowest risk multi-family startup. Often structured with separate meters for electric/gas, allowing tenants to pay their own utilities directly. Easy to refinance. Buying an Owner-Occupied Duplex.
2. Triplexes & Fourplexes (3-4 Units)
Provides greater cashflow insulation: If one tenant departs, you still have multiple remaining units covering the building expenses. Governed under residential rules (any building above 4 units requires commercial financing).
3. Local Tenant Safeguards & Rent Control
Cities like Richmond and San Pablo have strict local rent control policies and eviction protections. Eduardo’s 30+ years of legal regulatory understanding ensures you navigate local tenant laws and leases safely.
