Conventional Owner-Occupied

Conventional mortgages on 1-4 family owner-occupied properties require 5-20% down but offer more flexibility, faster approval, and no mandatory occupancy enforcement compared to FHA and VA loans.

Key takeaways

• Conventional mortgages are available on duplexes, triplexes, and quadplexes for owner-occupants with 5-20% down
• Interest rates are competitive (often lower than FHA if you put 15-20% down) and mortgage insurance (PMI) is removable at 80% LTV
• Occupancy requirement is looser: lenders define "primary residence" more broadly, allowing some flexibility
• Approval is faster (20-30 days typical) and underwriting is often simpler than FHA or VA
• Higher down payment requirement makes conventional less accessible to capital-constrained first-time investors, but more flexible overall

What conventional mortgages cover

Conventional mortgages are originated by banks and mortgage brokers, backed by Fannie Mae and Freddie Mac (government-sponsored enterprises, not government-backed insurance like FHA/VA). They're available on owner-occupied 1-4 family properties and have fewer regulatory constraints than FHA or VA products.

Key characteristics:

• Down payment: 5-20% (5% is high-risk tier; 10% is standard; 20% is zero-mortgage-insurance tier)
• Loan term: 15, 20, or 30 years (30 is standard)
• Property types: Single-family, duplex, triplex, quadplex (owner-occupied)
• Occupancy requirement: Primary residence (defined as where you intend to live most of the year; enforcement is minimal)
• Debt-to-income ratio: Typically under 43% (can stretch to 50% with strong compensating factors)
• Credit score: Minimum 620 (most lenders prefer 640+)
• Mortgage insurance: Removable at 80% LTV (unlike FHA)
• Interest rate: Competitive; often lower than FHA or VA if down payment is 15%+

The mortgage insurance (PMI) is the key differentiator from FHA. If you put down 10%, you pay mortgage insurance until you reach 80% LTV (loan-to-value). At that point, PMI drops off (you must request removal). FHA insurance is permanent unless you refinance, so conventional PMI is more favorable if you're building equity or if the property appreciates.

Down payment and PMI structure

If you put down 10% on a $450,000 duplex, the loan is $405,000. PMI is typically 0.5-1.5% annually depending on credit score and LTV. At 0.8%, annual PMI is $3,240, or $270/month.

When your loan balance reaches $360,000 (80% of $450,000 original value), you can request PMI removal. This happens through a combination of principal paydown and appreciation. If you pay down $45,000 in principal and the property appreciates 10% to $495,000, you reach 80% LTV after approximately 5-7 years (depending on rate of paydown).

Once PMI is removed, your payment drops by $270/month instantly. This is a powerful moment: you've built equity through occupancy and principal paydown, and your payment reward reflects that.

Compare this to FHA: you pay mortgage insurance for 30 years on the same loan, costing roughly $40,000-60,000 cumulatively. Conventional PMI costs $20,000-30,000 over the same period (declining as you pay down principal and request removal). The conventional advantage accelerates over time.

Occupancy requirements and enforcement

Conventional lenders define "primary residence" as the property where you intend to live and spend most of the year. This is looser than FHA's strict 12-month requirement. In practice, conventional lenders don't verify occupancy post-closing with the rigor of FHA. Some enforce it; others have minimal oversight.

This creates a gray area: you could theoretically close on a conventional mortgage, claim it as your primary residence, and move out within a few months without legal repercussion (though the loan document still requires owner-occupancy, and violation could theoretically trigger acceleration). Enforcement depends on the individual lender and servicer.

That said, relying on lax enforcement is risky. If a lender suspects fraud (occupancy statement on application, but no intent to occupy), they can accelerate the loan or demand refinance to investment terms. It's better to treat the occupancy requirement seriously and plan for 12-month owner-occupancy even on conventional loans.

Interest rates and approval speed

Conventional rates are typically 0.25-0.75% lower than FHA if your down payment is 15%+, because the lender's risk is lower (higher equity cushion). On a $405,000 loan (10% down), rates might be:

• FHA 6.8%
• Conventional 6.6%
• Difference: 0.2% per year, or about $810/year on the payment

At 20% down ($360,000 loan), the rate advantage grows: conventional might be 6.3% vs. FHA 6.8%, or 0.5% difference, saving roughly $1,800/year.

Approval timelines are faster on conventional (20-30 days typical vs. 30-45 days for FHA) because underwriting is less stringent. No appraisal for safety hazards, no funding fee, no mortgage insurance underwriting. Just standard credit, income, and asset review.

Underwriting and compensating factors

Conventional underwriting uses standard guidelines set by Fannie Mae and Freddie Mac. You need credit 620+, debt-to-income under 43%, and sufficient assets (typically 2 months' housing payment in reserves). If you're slightly above DTI or below credit score benchmarks, lenders look for compensating factors: large reserves (6-12 months), significant assets, strong income history, recent credit rebuilding.

The underwriting process is faster than FHA because there's no property inspection component. The lender relies on your appraisal (which is standard residential appraisal, not FHA-specific) and the title search. Minimal additional conditions means faster closing.

Application and pre-approval process

Conventional pre-approval requires:

1. Credit report and authorization
2. Income verification: recent W2s, pay stubs (2 months minimum), and often tax returns (2 years) for self-employed
3. Asset verification: bank statements (2 months), investment statements, retirement account balances
4. Employment verification: possibly a letter from your employer, especially if recent job change
5. Debt-to-income calculation

The entire process takes 3-5 business days with organized documentation. Pre-approval is valid for 60-90 days, after which you may need updated documentation.

Cost comparison: 10% down conventional vs. FHA

On a $450,000 purchase:

Cost Component	FHA (3.5% down)	Conventional (10% down)
Down Payment	$15,750	$45,000
Upfront Insurance/Fee	$7,599 (UFMIP 1.75%)	$0
Interest Rate	6.8%	6.6%
Monthly P&I	$2,910	$2,713
Monthly Mortgage Insurance	$295	$270
Total Monthly Cost (P&I+MI)	$3,205	$2,983
30-Year Total Cost	~$1,153,800	~$1,073,880

The conventional loan costs $79,920 less over 30 years despite higher down payment (you recover that in lower mortgage insurance). However, the conventional down payment is $29,250 more upfront, which may not be available to capital-constrained investors.

When conventional makes sense

Conventional financing is ideal for:

1. Investors with capital: If you have 20% down ($90,000 in this example), conventional eliminates PMI entirely, making it the cheapest option by far.
2. Repeat house hackers: If you've completed one cycle and have built equity, conventional financing on the next property avoids FHA overlap (you can only have one active FHA loan at a time; some lenders enforce this strictly).
3. Higher income: If your income is high enough that FHA DTI limits are constraining, conventional allows more leverage.
4. Fast approval needed: Conventional closing timelines are 5-10 days shorter than FHA on average.
5. Desire to avoid mortgage insurance: If you're planning to hold the property for 5+ years, PMI removal at 80% LTV beats FHA's permanent insurance.

Cash-out refinancing for the next house hack

After 12 months of occupancy on a conventional mortgage, you can do a cash-out refinance to fund your next down payment. If property A has appreciated 5% (to $472,500) and you've paid down $20,000 principal, your equity is $52,500. A cash-out refi could extract $30,000 (leaving 80% LTV), giving you capital for the next purchase.

This works equally well on FHA loans, but FHA requires refinancing into a new FHA loan or conventional loan after the 12-month period, whereas conventional is more flexible throughout.

Occupancy verification and risk

Unlike FHA (which sometimes verifies occupancy with property visits), conventional enforcement is minimal post-closing. Lenders rely on income and occupancy statement at application. However, insurance companies (which are required for all mortgages) may investigate claims or non-occupancy if there's reason to suspect the property is investment, not primary residence.

The risk is small but real: if you close on a conventional loan as primary residence and immediately convert to rental (violating the occupancy intent), an aggressive lender could demand occupancy verification, acceleration, or conversion to investment mortgage terms. More likely, they simply service the loan as-is without investigation. But the legal risk exists.

Playing it straight—occupying the property for 12 months—eliminates the risk entirely.

Comparison: FHA vs. VA vs. Conventional

For an investor with different capital positions:

No capital available: FHA (3.5% down) is only option unless VA-eligible.

$20,000-30,000 capital available: FHA is cheaper than conventional 10% down on total 30-year cost, despite higher down payment on conventional. Choose FHA if you have less capital; conventional if you have $45,000+ and want to avoid mortgage insurance.

$50,000+ capital available: Conventional 20% down is the cheapest option, eliminating mortgage insurance entirely. Most repeat house hackers use conventional for subsequent purchases.

VA-eligible: VA (0% down, no mortgage insurance) beats all options regardless of available capital. If eligible, always prefer VA.

Up to now, we've covered multifamily financing: duplexes, triplexes, and quadplexes. But house hacking isn't limited to buildings with separate units. Accessory dwelling units (ADUs)—garage conversions, backyard cottages, and studio apartments—offer another path. ADUs often generate higher per-square-foot returns and can operate under the same financing rules. We'll explore ADU house hacking next.
