Multifamily Investing California: 2-4 Unit Financing Guide

2-4 unit California properties are attractive investments: live in one unit, rent others.

Financing them has specific rules you need to understand.

What is multifamily

2-4 unit properties: Duplex, triplex, fourplex (owner-occupied or investment)

Owner-occupying 1 unit: Qualifies as "primary residence" with restrictions
All units for rent: Qualifies as investment property

Owner-occupancy advantage

Owner lives in 1 unit, rents other 1-3 units:

Better rates than pure investment (slightly lower)
Better down payment options (sometimes 5-10% vs 25%)
Owner-occupancy loan products available

Example: Buy $600K fourplex, live in unit 1, rent units 2-4

Financing options for 2-4 units

Option 1: Conventional (owner-occupied)

Live in one unit, rent others.

Down: 5-10% (sometimes 3.5%)
Rate: 6.0-6.75% (better than investment)
Qualification: Based on owner income + 75% of rental income
Best for: Owner wanting to live in property, rent other units

Option 2: Conventional (investment)

Pure investment (no owner occupancy).

Down: 25%
Rate: 6.75-7.25%
Qualification: Based on owner income + 75% rental income
Max properties: 10 total

Option 3: DSCR

Qualify purely on property cash flow.

Down: 20-25%
Rate: 7.5-9.5%
Qualification: DSCR ratio only
Properties: Unlimited

Rates comparison

$500K fourplex, owner-occupied:

• Conventional: 6.5% = $3,161/month
• DSCR: 8.0% = $3,441/month
• Difference: $280/month

$600K fourplex, pure investment:

• Conventional: 7.0% = $3,996/month
• DSCR: 8.5% = $4,511/month
• Difference: $515/month

Qualification example: Owner-occupied fourplex

Scenario:

• Property: $500K fourplex
• Owner lives in unit 1
• Units 2-4 rent for $2,000 each = $6,000/month

Qualification:

• Market rent for unit 1: $2,000
• Total market rent: $8,000/month ($96K annually)
• Conventional uses: 75% of $96K = $72,000/year rental income
• Owner income: $100,000/year
• Total qualifying income: ~$106,000
• New loan: $450K at 6.5% = $2,859/month
• DTI with existing debt: Usually acceptable

Key: Owner-occupancy allows you to count rental income + your income.

DSCR for fourplex

Same scenario with DSCR:

DSCR = $8,000/month rent ÷ $2,859 P&I = 2.80x

Easily qualifies (DSCR above 1.2x is strong).

With DSCR, property's cash flow is what matters, not your income.

Common strategy: House-hack fourplex

Buy fourplex:

• Live in unit 1
• Rent units 2-4 for $2,000 each
• Mortgage: $2,800/month
• Rent collected: $6,000/month
• Gross cash flow: $3,200/month (before expenses)

This is why fourplexes are popular—owner occupancy lowers qualification requirements.

California specific: Prop 13 benefit

California's Prop 13 (property tax cap) applies when you occupy the property as primary residence.

Buying fourplex as owner-occupied = lower property taxes than investor buying same property.

That's $3K-5K/year tax savings.

FHA multifamily option

FHA loans on 2-4 unit properties:

• Down payment: 3.5% (owner-occupied)
• Credit: 580+
• Rates: FHA rates + MIP

Can be cheaper than conventional for owner-occupied if credit is low.

Investment property 2-4 units

If you're NOT living in one unit:

All 4 units are rented:

• Down: 25%
• Rate: 7.0%+ (investment rates)
• Qualification: Harder (counts full against DTI)
• DSCR: May be better option

How many multifamily properties can you own?

Conventional: 10 total properties max (including primary residence)

DSCR: Unlimited

On 3rd-4th multifamily property, DSCR usually becomes better option to avoid DTI limits.

Expenses reduce cash flow

Remember to factor:

• Property taxes: 1-1.3% annually
• Insurance: $150-300/month per unit (high in CA)
• Vacancy: Assume 5-10% vacancy rate
• Maintenance: 1% annually
• Management: 8-10% of rents if professionally managed

$8,000 rent - $2,500 expenses = $5,500 net cash flow (roughly).

California market opportunity

2-4 unit California properties:

• Cheaper than 5+ unit (no commercial lender requirement)
• Better cash flow than single-family (multiple units)
• Owner-occupancy advantage (lower rates/down)
• Popular in Bay Area, LA, San Diego

Often priced better than single-family because fewer owner-occupancy buyers.

Bottom line

California 2-4 unit investing works especially well when:

• You live in one unit (better rates + lower down)
• Property generates positive cash flow
• You use DSCR if buying multiples (avoid DTI limits)
• You understand California tax/insurance costs

Owner-occupancy fourplex: Your personal residence + $3K/month cash flow.

That's the dream.
