Jumbo Mortgage Options in San Francisco: What Buyers Should Know in 2026

If you're buying an expensive home in San Francisco, you may need a jumbo mortgage — but probably not as quickly as you think.

For 2026, the conforming loan limit for a one-unit property in San Francisco County is $1,249,125.

That means there are really three financing ranges San Francisco buyers should understand:

1. Conforming financing up to the national baseline limit.

2. High-balance conforming financing above the national baseline but within San Francisco County's higher limit.

3. Jumbo financing when the loan amount exceeds the applicable conforming limit.

For a one-unit San Francisco property in 2026, a loan above $1,249,125 generally moves into true jumbo territory.

And that's where choosing the right mortgage strategy becomes especially important.

Jumbo lenders can differ substantially in how they evaluate income, reserves, stock compensation, self-employment, property type, debt-to-income ratios and down payment.

The best jumbo mortgage isn't necessarily the lender advertising the lowest rate. It's the loan that fits your financial profile and the San Francisco property you're actually buying.

## What Is a Jumbo Mortgage?

A jumbo mortgage is a home loan with a balance above the applicable conforming loan limit established by the Federal Housing Finance Agency.

Conforming loans can be purchased by Fannie Mae and Freddie Mac.

Jumbo mortgages fall outside those conforming loan limits.

Because of that, jumbo underwriting isn't standardized in exactly the same way.

Individual lenders and investors can establish different requirements.

That's extremely important for San Francisco buyers.

One jumbo lender might approve a scenario that another lender doesn't like at all.

## What Is the 2026 Jumbo Loan Limit in San Francisco?

Technically, there isn't a "jumbo loan limit."

There's a conforming loan limit.

Once the mortgage exceeds that applicable limit, it's generally considered jumbo.

For 2026, the one-unit conforming loan limits are:

National baseline: $832,750

San Francisco County: $1,249,125

San Francisco receives the higher limit because it qualifies as a high-cost housing area.

For 2026, San Francisco County's conforming limits are:

| Property Type | 2026 San Francisco County Limit |

| ------------- | ------------------------------: |

| 1 Unit        |                      $1,249,125 |

| 2 Units       |                      $1,599,375 |

| 3 Units       |                      $1,933,200 |

| 4 Units       |                      $2,402,625 |

That distinction can have a major impact on your financing.

## Is a $1 Million Mortgage a Jumbo Loan in San Francisco?

No — not necessarily.

This is one of the biggest misconceptions I see with Bay Area financing.

Suppose you're purchasing a San Francisco home for:

$1,250,000

and putting:

20% down

Your loan amount would be:

$1,000,000

Although that's significantly above the national conforming baseline, it's still below San Francisco County's 2026 one-unit conforming ceiling of $1,249,125.

That means you may potentially have access to high-balance conforming financing rather than needing a true jumbo loan.

Now consider a different purchase.

Purchase price:

$1,700,000

20% down:

$340,000

Loan amount:

$1,360,000

That loan amount exceeds San Francisco County's 2026 one-unit conforming limit.

Now we're generally looking at jumbo financing.

That's why I want to know both the purchase price and expected down payment before telling someone they need a jumbo mortgage.

## High-Balance Conforming vs. Jumbo in San Francisco

These terms get mixed together constantly.

### High-Balance Conforming

A high-balance conforming mortgage exceeds the national baseline conforming limit but stays within the higher limit permitted for a high-cost county like San Francisco.

### Jumbo

A jumbo mortgage exceeds the applicable conforming loan limit.

For a one-unit San Francisco property in 2026:

$900,000 loan: potentially high-balance conforming.

$1,150,000 loan: potentially high-balance conforming.

$1,249,125 loan: at the current one-unit San Francisco conforming ceiling.

$1,300,000 loan: generally jumbo.

Why does this matter?

Because conforming and jumbo financing can differ in:

* Interest rates

* Down-payment requirements

* Reserve requirements

* Credit requirements

* Income documentation

* Appraisal requirements

* Debt-to-income flexibility

* Property eligibility

Before assuming jumbo is better or worse, compare both whenever you're close enough to the dividing line.

## Should You Put More Down to Avoid a Jumbo Loan?

Sometimes.

But absolutely not automatically.

Imagine you're purchasing a one-unit property for:

$1,600,000

With 20% down:

$320,000

Loan:

$1,280,000

That puts the loan slightly above the 2026 San Francisco County conforming ceiling.

You could potentially put additional money down to bring the mortgage to:

$1,249,125

and explore high-balance conforming financing.

Should you?

Maybe.

But first I'd compare:

### Scenario A: Larger Down Payment + High-Balance Conforming

More cash invested into the property.

### Scenario B: 20% Down + Jumbo

More cash remains liquid.

Then compare:

* Interest rate

* APR

* Monthly payment

* Closing costs

* Reserve requirements

* Cash remaining after closing

* Long-term interest

* Investment opportunity cost

Putting another $30,000 into a house solely to say you avoided a jumbo loan doesn't automatically make financial sense.

Run the numbers.

## How Much Down Do You Need for a Jumbo Loan in San Francisco?

There is no single universal jumbo down-payment requirement.

That's another reason jumbo mortgage shopping can get confusing.

The required down payment can depend on:

* Loan amount

* Credit profile

* Property type

* Occupancy

* Income

* Assets

* Reserves

* Loan structure

* Lender or investor guidelines

Twenty percent down is common in jumbo conversations, but it should not be treated as a universal rule.

Some qualifying scenarios may permit less.

Other scenarios — especially larger loan amounts or more complicated properties — may require more.

The right question isn't:

"How much do jumbo loans require?"

It's:

"How much does the best available jumbo option require for my specific scenario?"

## Do Jumbo Loans Require Excellent Credit?

Jumbo lenders often place significant emphasis on credit.

But again, there isn't one universal jumbo minimum.

A lender may evaluate:

* Credit score

* Credit history

* Mortgage history

* Revolving debt

* Installment debt

* Recent inquiries

* Major derogatory credit events

* Overall financial strength

Because jumbo programs vary, a borrower who doesn't fit one lender's credit requirements may potentially fit another program.

That doesn't mean every credit profile can get a jumbo loan.

It means you shouldn't confuse one lender's rule with a universal jumbo rule.

## Why Reserves Matter With Jumbo Mortgages

Reserves are funds remaining after closing.

For example, suppose your total housing payment is:

$10,000 per month

and a particular jumbo program wants 12 months of qualifying reserves.

That would mean documenting:

$120,000

of eligible post-closing reserves.

Different programs may require more or less.

And not every asset is necessarily treated identically.

Potential reserve assets might include qualifying:

* Checking

* Savings

* Brokerage accounts

* Retirement accounts

* Other eligible liquid or vested assets

The exact treatment depends on the program.

This is particularly important in San Francisco because many borrowers have substantial net worth but don't necessarily keep enormous balances sitting in cash.

## Can Stocks and Investment Accounts Be Used for Jumbo Reserves?

Potentially.

This is common with Bay Area borrowers.

You may have:

* Brokerage accounts

* Company stock

* RSUs

* Retirement assets

* Money-market accounts

* Other investments

but relatively little sitting in a checking account.

That doesn't automatically mean you're short on reserves.

The lender needs to determine:

1. Whether the asset is eligible.

2. What percentage of its value can be counted.

3. Whether the funds are vested.

4. Whether liquidation is required.

5. Whether using the asset for closing affects the remaining reserve calculation.

This should be reviewed before you make an offer.

## How Do Jumbo Lenders Treat RSU Income?

This is a major Bay Area issue.

Many technology and corporate employees don't receive compensation through salary alone.

Their income may include:

* Base salary

* Bonus

* Commission

* Restricted stock units

* Equity compensation

That can create a mismatch between:

What you actually earn

and

What a mortgage underwriter can document as qualifying income.

Depending on the program and your history, certain RSU income may potentially be considered.

But treatment can vary.

A lender may examine factors such as:

* Vesting history

* Continuance

* Employer

* Award documentation

* Distribution history

* Current value

* Frequency

If a meaningful portion of your compensation comes from equity, don't wait until you're in escrow to ask whether it counts.

## What About Bonus Income?

Bonus income can also be important.

Someone might have:

$200,000 base salary

plus

$100,000 annual bonus

On paper, that's $300,000 in compensation.

But mortgage underwriting has to determine what portion can be considered stable qualifying income.

The lender may review historical earnings and likelihood of continuance.

This can be especially important when qualifying for a large mortgage.

## Jumbo Loans for Self-Employed San Francisco Buyers

Self-employed borrowers often have a different problem.

Their business may generate substantial cash flow, but their personal tax returns may show significantly less taxable income after legitimate business deductions.

Traditional jumbo underwriting may analyze:

* Personal tax returns

* Business tax returns

* K-1s

* Profit-and-loss statements

* Balance sheets

* Business ownership

* Business liquidity

* Income trends

For some self-employed borrowers, traditional full-documentation jumbo financing works perfectly well.

For others, it doesn't reflect their actual financial strength.

That's when alternative programs may be worth reviewing.

## Can You Get a Jumbo Bank-Statement Loan?

Potentially.

Bank-statement programs are generally part of the Non-QM market rather than traditional conforming financing.

Instead of relying solely on tax-return income, an eligible program may evaluate qualifying deposits over a specified period.

This can be useful for certain:

* Business owners

* Consultants

* Entrepreneurs

* Independent contractors

* Self-employed professionals

But bank-statement loans shouldn't automatically be the first choice just because you're self-employed.

I would first determine whether you qualify conventionally.

If you do, compare that option.

If you don't, then evaluate alternative documentation.

## Jumbo Loans for High-Net-Worth Borrowers

Some San Francisco buyers have a substantial balance sheet but relatively unusual taxable income.

For example:

$4 million in investments

but income that doesn't fit traditional underwriting neatly.

Depending on the scenario, there may be jumbo or Non-QM programs designed around:

* Asset utilization

* Asset depletion

* Alternative income documentation

* Significant liquid assets

* Other qualifying structures

These aren't one-size-fits-all products.

But they're important because a traditional tax-return analysis isn't always the only way a financially strong borrower can qualify.

## Can You Get a Jumbo Loan on a San Francisco Condo?

Yes, potentially.

But with a condo, we need to qualify two things:

1. The borrower.

2. The condominium project.

That's especially important in San Francisco.

The lender may review issues involving:

* HOA financial condition

* Insurance

* Litigation

* Commercial space

* Delinquencies

* Owner occupancy

* Structural concerns

* Project characteristics

* Single-entity ownership

A borrower can be extraordinarily well qualified and still encounter a financing problem because of the building.

So condo review shouldn't be an afterthought.

## What if the Condo Is Non-Warrantable?

A condo may be considered non-warrantable when it doesn't satisfy certain conventional project requirements.

That doesn't necessarily mean:

The property can't be financed.

It may mean:

We need a different financing channel.

Potential solutions can include:

* Portfolio lending

* Non-QM financing

* Specialized non-warrantable condo programs

* Certain jumbo investors

The exact solution depends on why the project doesn't qualify conventionally.

This is one of the reasons I don't want San Francisco condo buyers shopping based only on an advertised interest rate.

We need to understand the building.

## Can You Use Jumbo Financing for a TIC in San Francisco?

A tenancy-in-common property is a completely different financing conversation.

San Francisco has a well-established TIC market, but TIC interests aren't financed the same way as a standard condominium.

Traditional Fannie Mae, Freddie Mac and conventional jumbo structures generally aren't the starting point for fractional TIC financing.

Instead, TIC financing typically requires lenders or programs specifically comfortable with fractional TIC ownership.

If you're considering a TIC, tell me immediately.

Don't get preapproved for a generic jumbo loan and assume that approval transfers to a TIC interest.

Property structure matters.

## Condo vs. TIC: Why the Distinction Matters

Imagine two properties listed at:

$1,400,000

One is a condominium.

One is a fractional TIC interest.

Same price.

Same borrower.

Same neighborhood.

Completely different financing possibilities.

This is why San Francisco mortgage planning requires more than asking:

"What's your jumbo rate?"

The legal and ownership structure of the property can determine which lending options are available.

## What About a Two- to Four-Unit Property?

San Francisco County's conforming loan limits increase for multi-unit properties.

For 2026:

2 units: $1,599,375

3 units: $1,933,200

4 units: $2,402,625

That can create a surprising result.

A loan amount that would be jumbo on a single-family home may potentially still fall within conforming limits when financing an eligible multi-unit property.

For example:

A $1.5 million loan on a one-unit property exceeds San Francisco County's one-unit conforming ceiling.

But the 2026 two-unit conforming limit is $1,599,375.

Property type changes the analysis.

## Can Rental Income From Another Unit Help You Qualify?

Potentially.

If you're buying an eligible multi-unit property and occupying one unit as your primary residence, qualifying rental income from the other units may potentially be considered under applicable underwriting rules.

That can be extremely relevant in San Francisco.

A duplex might be expensive.

But it may also produce substantial rent from the second unit.

The lender needs to evaluate:

* Lease information when applicable

* Market rent

* Appraisal documentation

* Your experience and occupancy

* Applicable program requirements

Don't simply subtract the expected rent from the mortgage payment yourself.

Mortgage underwriting has specific rules for how rental income is calculated.

## What About ADU Income?

Accessory dwelling units are another increasingly important part of California housing.

If the property includes an ADU, potential rental income treatment depends on the loan program, property configuration and underwriting guidelines.

If your ability to qualify depends on ADU income, identify that early.

We need to know whether the selected financing program will recognize it.

## Fixed-Rate vs. ARM Jumbo Mortgages

Jumbo borrowers may have both fixed-rate and adjustable-rate mortgage options.

A fixed-rate mortgage gives you payment stability.

An ARM may offer a different initial rate structure, but the rate can adjust later according to the loan terms.

Which is better depends on factors such as:

* Expected time in the home

* Expected future income

* Liquidity

* Risk tolerance

* Rate difference

* Adjustment structure

* Refinance expectations

Don't choose an ARM solely because its starting rate looks lower.

Understand the entire structure.

## Should You Pay Points on a Jumbo Loan?

Maybe.

But the larger the loan, the more important the math becomes.

Suppose you're borrowing:

$1,500,000

One point equals:

$15,000

That's real money.

If paying $15,000 reduces your monthly payment by $250, the simple break-even period would be:

60 months

or five years.

If you sell or refinance before then, paying that point may not have delivered the expected benefit.

That's why I want to compare:

* Par or low-cost pricing

* Discount-point options

* Monthly savings

* Break-even period

* Expected holding period

The lowest advertised rate isn't necessarily the least expensive mortgage.

## How Much Do Jumbo Rates Differ Between Lenders?

They can differ.

Jumbo mortgages are particularly lender-specific because different banks, mortgage companies and investors can have different appetites at different times.

One institution may be aggressive on:

$1.5 million loans at 70% loan-to-value.

Another may be more competitive at:

$2.5 million with significant reserves.

Another may specialize in:

Self-employed borrowers.

Another may have a strong:

Non-warrantable condo program.

That's why jumbo borrowers can benefit from comparing more than one lending channel.

## Is a Bank Always Better for a Jumbo Loan?

No.

Banks can be very competitive in jumbo lending, particularly when they want a broader banking relationship with the borrower.

But that doesn't mean a bank automatically has the best mortgage.

Compare:

* Rate

* Points

* Fees

* Underwriting

* Reserve requirements

* Income treatment

* Property eligibility

* Appraisal process

* Relationship requirements

* Ability to close the actual transaction

A great rate on a loan that doesn't fit your income or property isn't useful.

## What Are Relationship Discounts?

Some banks may offer pricing incentives when borrowers move or maintain substantial assets with the institution.

For example, a bank may offer a mortgage pricing benefit in exchange for bringing over qualifying investment or deposit assets.

That can be worth considering.

But evaluate the whole relationship.

Ask:

* How much money must be transferred?

* How long must it remain?

* Is the mortgage discount permanent?

* Are there investment-management costs?

* Does moving the assets create tax consequences?

* Is the mortgage still competitive without the relationship?

Don't move a seven-figure investment account to save money on a mortgage without understanding both sides of the equation.

## How Should You Compare San Francisco Jumbo Mortgage Options?

I would compare jumbo financing across at least these categories:

### 1. Loan Structure

Fixed or adjustable?

### 2. Interest Rate

What is the actual note rate?

### 3. Points and Fees

What are you paying to obtain that rate?

### 4. Down Payment

How much cash must you invest?

### 5. Reserves

How much needs to remain after closing?

### 6. Income Treatment

How will salary, bonus, RSUs, self-employment or other income be calculated?

### 7. Property Eligibility

Does the program work for the condo, multi-unit property or other property you're purchasing?

### 8. Prepayment Terms

Are there any applicable restrictions for the particular loan structure?

### 9. Underwriting Strength

Has the lender actually reviewed the difficult parts of your file?

### 10. Total Financial Strategy

How much liquidity remains after closing?

That's a better comparison than:

Lender A: 6.X%

versus

Lender B: 6.Y%

## Why Preapproval Matters More With Jumbo Financing

A basic prequalification isn't enough for many San Francisco jumbo buyers.

If you're preparing to make a $1.5 million, $2 million or $3 million purchase, I'd rather identify the difficult underwriting questions before you find the property.

That can include:

* RSU calculations

* Bonus income

* Business income

* Tax returns

* Large deposits

* Asset eligibility

* Reserve calculations

* Condo issues

* Existing real estate

* Rental income

* Multiple financed properties

The stronger the review before the offer, the fewer surprises we should encounter afterward.

## How I Approach Jumbo Financing in San Francisco

When I work with a San Francisco jumbo buyer, I don't want to immediately force the borrower into one loan category.

First, we determine the actual financing need.

That means reviewing:

* Purchase price

* Down payment

* Desired cash remaining after closing

* Income structure

* Credit

* Assets

* Reserves

* Existing real estate

* Property type

* Occupancy

* Expected ownership period

Then we identify the appropriate financing channels.

Depending on the scenario, that might include:

* High-balance conforming

* Traditional jumbo

* Portfolio jumbo

* Bank-statement financing

* Asset-based or alternative-documentation financing

* Non-warrantable condo financing

* Specialized TIC financing

Sometimes the answer is obvious.

Sometimes two completely different structures both work.

That's when we compare the numbers.

## Frequently Asked Questions About Jumbo Loans in San Francisco

### Where can I find jumbo mortgage options in San Francisco?

Jumbo mortgages are available through banks, credit unions, mortgage lenders, brokers and other private lending channels. Because jumbo underwriting and pricing can vary substantially, it can be useful to work with a mortgage professional who can evaluate multiple financing structures rather than assuming one lender fits every high-balance borrower.

### What is the jumbo loan threshold in San Francisco for 2026?

For a one-unit property, San Francisco County's 2026 conforming loan limit is $1,249,125. A loan amount above the applicable conforming limit is generally considered jumbo.

### Is a $1 million mortgage jumbo in San Francisco?

Not necessarily. A $1 million one-unit mortgage is below San Francisco County's 2026 conforming ceiling and may potentially qualify as high-balance conforming financing.

### Is a $1.5 million mortgage jumbo in San Francisco?

For a one-unit property in 2026, yes, a $1.5 million loan exceeds San Francisco County's $1,249,125 conforming limit and would generally require jumbo or another non-conforming financing structure.

### How much down do I need for a jumbo mortgage?

There is no universal jumbo down-payment requirement. The required equity can vary based on loan amount, credit, occupancy, property type, reserves and the selected lender or investor.

### Do jumbo loans require 20% down?

Not universally. Twenty percent is common, but some qualifying programs may permit less while other scenarios may require more.

### Do jumbo loans require more reserves?

Jumbo programs often have meaningful reserve requirements, but the exact requirement varies by lender, loan amount and borrower profile.

### Can RSUs be used to qualify for a jumbo mortgage?

Potentially. Treatment of RSU income varies by program and may depend on vesting history, receipt history, continuance and documentation.

### Can self-employed borrowers get jumbo loans?

Yes. Traditional jumbo financing may use tax-return income, while qualifying borrowers may also have access to alternative programs such as bank-statement or other Non-QM financing.

### Can I use a jumbo loan to buy a condo in San Francisco?

Potentially. Both the borrower and condominium project must satisfy the requirements of the selected loan program.

### Can I finance a non-warrantable condo?

Potentially. Specialized jumbo, portfolio or Non-QM programs may finance certain projects that don't satisfy standard conventional project requirements.

### Can I get a jumbo loan for a San Francisco TIC?

Fractional TIC financing is specialized and generally requires a lender or program that specifically finances TIC interests. Don't assume a standard jumbo preapproval applies to a TIC.

### Are the conforming limits higher for duplexes and multi-unit properties?

Yes. San Francisco County's 2026 limits are $1,599,375 for two units, $1,933,200 for three units and $2,402,625 for four units.

### Is jumbo always more expensive than conforming?

No. Jumbo and conforming pricing changes with market conditions and borrower characteristics. Compare actual available terms rather than assuming one category always has the lower rate.

### Should I put more money down to stay under the conforming limit?

Sometimes, but only after comparing the additional cash required with the pricing and terms of the jumbo alternative.

### Should I choose the jumbo lender with the lowest interest rate?

Not based on rate alone. Compare points, fees, underwriting requirements, reserves, property eligibility, income treatment and total cost.

## The Bottom Line

San Francisco buyers have more mortgage options than the word "jumbo" suggests.

For 2026, the one-unit conforming loan ceiling in San Francisco County is $1,249,125, so many borrowers who think they need jumbo financing may actually fit within high-balance conforming guidelines.

Above that amount, jumbo financing becomes more lender-specific.

That's where details matter.

A borrower earning W-2 salary and bonus may need a different solution than a tech employee receiving substantial RSUs.

A business owner may need a different structure than a salaried executive.

A standard condo may finance differently than a non-warrantable condo.

And a San Francisco TIC is a different financing category altogether.

The goal isn't to find a product labeled "jumbo." The goal is to find the mortgage structure that fits your income, assets, property and long-term financial plan.

If you're buying a higher-priced home, condo, multi-unit property or TIC in San Francisco or elsewhere in the Bay Area, I can help you determine whether high-balance conforming, jumbo or a more specialized financing option makes the most sense before you make an offer.
