You do not automatically need 20% down to buy a Bay Area home, but the minimum available to you depends on the loan program, loan amount, property and your qualifications. Some eligible conventional borrowers can use low-down-payment programs; that does not mean a 3% option is available for every Bay Area purchase. The practical question is how much cash you need for the down payment, closing costs and reserves while keeping the monthly payment comfortable.
Research reviewed September 15, 2026. Dollar examples are hypothetical planning calculations, not listings, rate quotes or loan approvals. Cover image is illustrative.
Start with three separate cash amounts
- Down payment: the portion of the purchase price you pay rather than finance with the main mortgage.
- Cash to close: the remaining amount due to complete the transaction after accounting for the loan, closing costs, deposits and permitted credits.
- Money retained after closing: emergency savings, moving expenses, repairs and any lender-required reserves.
A buyer with $200,000 saved cannot necessarily use all $200,000 as a down payment. The CFPB’s down-payment planning guidance recommends setting aside money for other needs and an emergency cushion before deciding what is available for closing. Keep retirement and other long-term goals in the calculation.
What 5%, 10% and 20% look like at Bay Area price points
| Hypothetical home price | 5% down | 10% down | 20% down |
|---|---|---|---|
| $1,000,000 | $50,000 | $100,000 | $200,000 |
| $1,500,000 | $75,000 | $150,000 | $300,000 |
| $2,000,000 | $100,000 | $200,000 | $400,000 |
These amounts exclude closing costs and reserves. A lender must confirm the permitted loan-to-value ratio, loan size, occupancy, property eligibility, credit, income and asset requirements. Do not treat the smallest percentage in a table as a mortgage offer.
Why the 2026 county loan limit can change the decision
The FHFA’s 2026 county loan-limit list sets the one-unit conforming limit at $1,249,125 for Santa Clara, Alameda, Contra Costa, San Francisco and San Mateo counties. This is a mortgage-balance limit, not a home-price ceiling. Other counties and multi-unit properties can have different limits.
At a hypothetical $1.5 million price:
- 10% down leaves a $1,350,000 mortgage, above that one-unit limit.
- 20% down leaves a $1,200,000 mortgage, below that limit.
- Subtracting $1,249,125 from $1,500,000 gives $250,875, or about 16.73% of the price. That is the arithmetic needed to bring this example’s mortgage to the limit—not a statement that the borrower or loan qualifies.
A loan above the applicable conforming limit generally falls into jumbo financing, where lender requirements and pricing vary. A loan below the limit still has to meet underwriting requirements. Also, high-balance conforming loans and standard low-down-payment products are not interchangeable: Fannie Mae applies specific high-balance eligibility rules. Ask your lender to compare the actual options on both sides of the loan-size threshold.
For a $2 million home, even 20% down leaves a $1.6 million mortgage—still above the five counties’ one-unit limit. “Twenty percent down” does not by itself mean “conforming loan.”
Is putting less than 20% down a mistake?
Not necessarily. A smaller down payment may preserve cash, while a larger one reduces the amount borrowed. The tradeoff includes payment, interest rate, mortgage insurance, closing costs and your remaining liquidity—not just the percentage.
The CFPB explains that mortgage insurance typically applies when putting less than 20% down and protects the lender. Its cost and structure depend on the loan. Compare a written loan scenario with 10% down against one with 20% down using the same property and date. Ask how mortgage insurance may end for the specific product; do not assume all loan types follow the same cancellation rules.
Eligible veterans and service members may have a different route. VA purchase loans can offer no down payment and no monthly mortgage insurance, subject to eligibility, appraisal and lender requirements. A funding fee may apply unless exempt, and closing costs still need a plan. No down payment does not mean no cash needed.
A cash-to-close example that avoids double-counting the deposit
Suppose a buyer agrees to a $1 million purchase with 10% down. Assume $20,000 in closing costs and prepaids, a $30,000 deposit already paid, and a permitted $5,000 seller credit toward eligible costs:
- Down payment: $100,000.
- Plus costs and prepaids: $20,000.
- Less deposit already paid: $30,000.
- Less permitted credit: $5,000.
- Illustrative remaining cash to close: $85,000.
The deposit is part of the buyer’s contribution, not another down payment on top. Total buyer cash paid in this example is $115,000, including the earlier deposit. If the buyer wants $40,000 left after closing, the planning target would be $155,000 before paying that deposit, excluding any additional moving or repair expenses. These costs and reserve amounts are examples, not recommended minimums or local fee estimates.
Credits have program limits and permitted uses; do not assume a seller credit can replace the required down payment. Confirm the final figures on the lender’s disclosures and settlement documents. Our California closing-cost guide explains the different categories.
Can assistance reduce the cash you need?
Possibly, but assistance is not automatically a grant or available to every buyer. CalHFA’s MyHome program is a deferred-payment junior loan with borrower, property and first-mortgage requirements. Confirm current eligibility, funding availability, education requirements and repayment terms with an approved lender. A program’s existence does not establish that you qualify or that funds are reserved for your purchase.
For gifts or other sources of funds, ask the lender what documentation and restrictions apply before moving money. Keep an understandable paper trail and distinguish a genuine gift from money you must repay. Do not build an offer around unapproved assistance or an unverified future payment.
Use this lender-comparison checklist
- Choose a target property price and county, plus the occupancy and property type.
- Request two or three down-payment scenarios that are actually available to you.
- Compare the total payment, mortgage insurance, points, lender fees and cash to close.
- Identify the loan category and any reserve or appraisal requirements.
- Check how much accessible cash remains after closing.
- Stress-test taxes, insurance, HOA costs and near-term repairs.
Use our mortgage calculator to explore down-payment scenarios, replacing defaults with current lender and property estimates. Read the Bay Area preapproval guide before requesting financing terms. A calculator cannot determine eligibility or guarantee a rate.
Frequently asked questions
Can I buy a Bay Area home with 3% down?
Some eligible buyers and properties qualify for low-down-payment conventional programs. Eligibility depends on the specific product and loan amount; a general 3% advertisement should not be applied automatically to a high-balance or jumbo purchase.
Do I need 20% down to avoid a jumbo loan?
Not always. Compare the resulting mortgage amount with the applicable county and property-unit limit. The $1.5 million and $2 million examples above show why price changes the answer.
Is my earnest-money deposit additional to my down payment?
It is generally credited toward the transaction at closing. Review the actual settlement accounting and contract; do not count the same deposit twice in your cash plan.
What should I prepare before a consultation?
Bring your price range, target cities, available cash and desired reserve cushion. Vikas Shah can help coordinate the property search with your financing plan. For the complete sequence, see the California home-buying process guide.
