Jumbo vs Conforming Loans in California: Which Do You Need?

In most of California, the line between conforming and jumbo is $832,750.

Borrow $832,750? Conforming.
Borrow $832,751? Jumbo.

That $1 can cost you 0.5% in interest rate and stricter qualification.

I'm Bill McCoy (CA DRE #01212512). I place both conforming and jumbo loans daily. Here's what you need to know.

What Is a Conforming Loan?

Conforming loan = meets Fannie Mae and Freddie Mac guidelines, including loan limits.

2026 Loan Limits:

• Standard counties: $832,750
• High-cost counties: $1,249,125

High-cost California counties include:

• Los Angeles, Orange, San Diego
• San Francisco, San Mateo, Santa Clara, Alameda, Marin
• Ventura, Santa Barbara, Santa Cruz, Napa
• Full list: FHFA.gov

What Is a Jumbo Loan?

Jumbo loan = exceeds conforming loan limits.

In California:

• Standard counties: Over $832,750
• High-cost counties: Over $1,249,125

Jumbo loans are NOT backed by Fannie/Freddie. Lenders hold the risk, so they have stricter requirements.

Conforming vs. Jumbo Comparison

Feature	Conforming	Jumbo
Loan limit	Up to $832,750 or $1,249,125	No limit
Interest rate	6.00-6.50% (2026)	6.25-7.00%
Credit score	620 minimum	700+ typically
Down payment	3-20%	10-20%
DTI max	43-50%	38-43%
Reserves	2-6 months	6-12 months
PMI	Required if <20% down	Sometimes required
Underwriting	Standard	Stricter

Jumbo Loan Requirements (Stricter)

Credit Score

Conforming: 620 minimum, 740+ for best rates
Jumbo: 700 minimum, 740+ for best rates

Below 700? You'll struggle to find jumbo lenders.

Down Payment

Conforming: 3% (first-time buyers), 5% (repeat buyers), 20% (no PMI)
Jumbo: 10-20% typically (some lenders allow 10%, most want 20%)

Debt-to-Income Ratio

Conforming: Up to 50% with strong compensating factors
Jumbo: Usually maxes at 43%, some lenders cap at 38%

Example:

• Income: $200,000/year = $16,667/month
• Max DTI (43%): $7,167/month
• Existing debts: $1,500/month
• Available for housing: $5,667/month
• Max home (jumbo): ~$1M (at 6.75%, including taxes/insurance)

Reserves

Conforming: 2-6 months of mortgage payments in savings
Jumbo: 6-12 months (sometimes 12+ months for loans over $2M)

Example:

• Jumbo loan: $1.5M
• Monthly payment: $10,000
• Required reserves: $60,000-$120,000 in the bank after closing

That's a lot of cash you can't touch.

Income Documentation

Conforming: W-2s + paystubs OR tax returns (self-employed)
Jumbo: Same, but stricter scrutiny. Lenders may require CPA letters, audited financials, or proof of business stability.

See self-employed mortgage requirements

Property Restrictions

Condos:

• Conforming: Most FHA/Fannie-approved condos OK
• Jumbo: Stricter. Some lenders avoid condos entirely or require 25% down.

Investment properties:

• Conforming: 15-25% down
• Jumbo: 25-30% down + higher reserves

Rate Differences

Jumbo rates are typically 0.25-0.5% HIGHER than conforming.

2026 Example (California):

• Conforming ($832K): 6.25%
• Jumbo ($1.2M): 6.75%

Why? Jumbo loans are riskier for lenders (no Fannie/Freddie backing).

Monthly payment difference (on $832K):

• At 6.25%: $5,123
• At 6.75%: $5,397
• Extra cost: $274/month = $98,640 over 30 years

High-Balance Conforming (The Sweet Spot)

In high-cost counties, conforming loans go up to $1,249,125.

This is huge.

Example:

• Buy a $1,200,000 home in LA County
• Put 20% down ($240K)
• Loan: $960,000
• Conforming loan (because LA is high-cost)
• Rate: 6.25% (conforming rates)

vs. if LA weren't high-cost:

• Same loan = jumbo
• Rate: 6.75%
• You save 0.5% just because of county limits

Broker's Tip: If you're buying in a high-cost county and borrowing under $1,249,125, you get conforming rates on loans that would be jumbo elsewhere. This is a massive advantage.

When Jumbo Makes Sense

1. You're buying a high-value home
California median in coastal areas = $1M+. You need jumbo.

2. You have excellent credit and income
Jumbo requirements aren't a problem.

3. You want a large loan with minimal down
Some jumbo programs allow 10% down on $2M+ homes.

4. You're refinancing a large mortgage
Cash-out or rate-and-term refi on jumbo balance.

When to Avoid Jumbo (If Possible)

1. Your credit is under 720
You'll pay a premium or get denied.

2. You're self-employed with fluctuating income
Jumbo underwriting is brutal on inconsistent income.

3. You're stretching to afford the payment
Jumbo lenders want to see breathing room (low DTI, high reserves).

4. You can stay under conforming limits
Put 10% more down and get a conforming loan instead.

Example:

• Home price: $900,000
• 10% down: $90K → loan $810K (conforming) ✓
• 5% down: $45K → loan $855K (jumbo) ✗

Extra $45K down saves you 0.5% rate = $50K+ over 30 years.

Super Jumbo Loans ($2M+)

Loans over $2M = super jumbo.

Requirements:

• 20-30% down
• 740+ credit
• Very low DTI (under 38%)
• 12+ months reserves
• Significant liquid assets
• Strong income history

These are portfolio loans (lender holds them). Each bank has its own rules.

Jumbo Refinance

Refinancing a jumbo loan:

• Same strict requirements as purchase
• Must have 20%+ equity
• 700+ credit
• Strong income and reserves

Cash-out refinance:

• Max 75-80% LTV
• Higher rates
• More scrutiny

See investment property refinancing

Strategies to Avoid Jumbo

1. Put More Down

Example:

• Home: $900,000
• 5% down ($45K) → $855K loan (jumbo)
• 10% down ($90K) → $810K loan (conforming)

Save 0.5% rate by putting an extra $45K down.

Is it worth it?

• Rate savings: ~$300/month = $108K over 30 years
• Opportunity cost of $45K (could invest instead)

Usually worth it if staying 10+ years.

2. Use a Piggyback Loan

80-10-10 structure:

• 10% down payment
• 80% first mortgage (conforming)
• 10% second mortgage (HELOC or home equity loan)

Example:

• Home: $1,000,000
• Down: $100K (10%)
• First: $800K (conforming, 6.25%)
• Second: $100K (HELOC, 8.5%)

Blended rate is lower than straight jumbo at 6.75%.

Pros: Avoid jumbo, lower overall rate
Cons: Two loans, HELOC rate is variable

3. Buy in a High-Cost County

If you're flexible on location, buying in LA/OC/SD/SF gets you conforming rates up to $1,249,125.

Ventura County (high-cost) vs. Kern County (standard):

• Same $900K loan
• Ventura: Conforming (6.25%)
• Kern: Jumbo (6.75%)
