East Bay Down Payment Assistance Programs for 2026 Buyers

Most East Bay buyers who tell me they cannot afford a home are wrong about which number is stopping them. They can carry the payment. What they cannot do is produce two hundred thousand dollars in cash on a Tuesday. That is a down payment problem, not an affordability problem, and California has built more machinery to solve it than almost any state in the country — a county second mortgage worth up to $210,000, a two-county program that will cover up to 40% of the purchase price, a state agency junior loan, and a federal tax credit that pays you back every April for thirty years. I am Karan Singh, a licensed REALTOR® and Broker with eXp Realty serving Castro Valley, Hayward, Fremont, Dublin, Pleasanton and Livermore, and I have watched buyers walk away from these programs because nobody sat them down and explained which ones stack, which ones are closed right now, and which ones will quietly disqualify their offer if they bring them to the wrong listing. Here is the full map for 2026.

How Much Down Payment You Actually Need in Alameda and Contra Costa Counties

How much do I need for a down payment to buy a house in the East Bay?
There is no fixed answer, because the two counties price very differently. Redfin reported an Alameda County median sale price near $1.2 million for the three months ending May 2026, up 5.4% year over year, against roughly $837,000 in Contra Costa County, up 2.1%. Conventional financing starts at 3% down for qualified first-time buyers and FHA at 3.5%, so your true floor is far lower than the 20% most people assume.

The 20% figure is folklore that refuses to die, and it is costing people years. The National Association of REALTORS® 2025 Profile of Home Buyers and Sellers put the median down payment for first-time buyers at 10% — a record high since 1989, and still only half of what the average person at a dinner party will tell you is required. Repeat buyers put down a median of 23%, but they are recycling equity from a home they already owned for a record eleven years. Those are two completely different financial situations reported as one statistic, and conflating them is how a first-time buyer talks themselves out of the market.

What actually determines your number is the intersection of three things: the price band you are shopping, the loan product you qualify for, and how competitive the property is. In practice that is why the same buyer might need 3.5% in one part of the East Bay and 20% in another. A $700,000 townhome in Hayward or a condo in San Leandro is a different capital problem than a $1.4 million single-family home in Dublin. The same NAR study found that first-time buyers now make up just 21% of the national market, the lowest share since tracking began in 1981, and the median first-time buyer age has risen to 40. The down payment barrier is the single largest reason for both numbers.

Rates matter here too. Freddie Mac's Primary Mortgage Market Survey, published through the Federal Reserve Bank of St. Louis on FRED, put the 30-year fixed average at 6.69% as of August 6, 2026. At that level every dollar of assistance does double duty — it lowers the loan balance and eases mortgage insurance pressure at the margin.

AC Boost: Alameda County's $210,000 Second Mortgage

What is AC Boost and who qualifies?
AC Boost is Alameda County's down payment assistance program, funded by voter-approved Measure A1, administered by the Alameda County Housing and Community Development Department and managed by the nonprofit Hello Housing. It provides shared-appreciation loans up to $210,000 for households under 100% of Area Median Income and up to $160,000 for households between 100% and 120% AMI, with no interest and no monthly payment.

This is the largest county-level down payment program in the region and the one East Bay buyers most consistently do not know exists. The structure matters: it is a silent second mortgage. You make no monthly payment on it while you own the home. Repayment is triggered when the home sells, when you take cash out in a refinance, when you stop occupying it as your primary residence, or when the 30-year term ends. Because it is a shared-appreciation loan, you repay the principal plus a share of the home's appreciation rather than accrued interest.

Eligibility centers on connection to the county, not just residence. Alameda County has structured AC Boost for first-time buyers who currently live in the county, work in the county, or were displaced from the county within the last ten years. That displacement clause is deliberate and it is underused — if you were priced out of Oakland or Hayward within the last decade and have been renting in the Central Valley since, you may still qualify to come back. The county has also built in limited preferences for educators and first responders.

Two practical notes I give every client considering AC Boost. First, the pre-application is not the application; Alameda County runs a pre-application intake through acboost.org and by phone at (510) 500-8840, and the timing of intake windows governs everything downstream. Second, an AC Boost buyer needs a listing agent who understands the program, because a shared-appreciation second lien adds documentation and coordination to escrow. If you are shopping in Hayward or Castro Valley — both squarely within the program's geography — that coordination is something your buyer's agent should be handling before you write, not after.

The Home Access Program: Up to $200,000 Across Both Counties

Can I get down payment help in Contra Costa County too?
Yes. The Home Access Program, administered by Housing Trust Silicon Valley, provides down payment assistance of up to 40% of the purchase price, capped at $200,000, for first-time buyers purchasing in either Alameda or Contra Costa County. It is structured as a 30-year deferred loan with no monthly payments, and household income must not exceed 80% of Area Median Income for the county where the property sits.

Home Access is the newer entrant and the one that changes the math most dramatically at the lower end of the market, because it is expressed as a percentage of purchase price rather than a flat dollar cap. On an $800,000 purchase, 40% is $320,000 — above the cap, so you receive the $200,000 maximum. On a $450,000 condo, 40% is $180,000, and the percentage governs. Either way, a buyer who can qualify for the payment but has been saving for six years just had the timeline collapse.

The tradeoff is the income ceiling. At 80% of Area Median Income, Home Access sits meaningfully below AC Boost's 120% AMI threshold, which means the two programs serve overlapping but distinct households. A dual-income tech household in Dublin will usually clear AC Boost and fail Home Access. A single-income household, a household on a public-sector salary, or a household where one earner recently lost a job may qualify for Home Access and receive substantially more. Housing Trust Silicon Valley has confirmed the program covers single-family homes, townhomes and condominiums in both counties.

The county distinction here is not cosmetic. Because Home Access is capped as a percentage of price and Contra Costa County's median sale price runs roughly $360,000 below Alameda County's, the same assistance dollars reach considerably further west-to-east across the county line. That is one of several reasons I tell buyers to look at both counties before deciding where to focus a search.

CalHFA MyHome and Dream For All: What Is Open and What Is Not

Is the California Dream For All program still accepting applications?
Not right now. The California Housing Finance Agency ran the 2026 Dream For All application window from February 24 through March 16, 2026, with $150 million to $200 million allocated and recipients selected by random drawing rather than first-come-first-served. That window has closed. CalHFA's MyHome Assistance Program, by contrast, is an ongoing program with no application lottery.

These two CalHFA programs get confused constantly, and the confusion has real cost. Dream For All is the headline program — a shared-appreciation loan offering qualified first-generation buyers up to 20% of the purchase price or appraised value, capped at $150,000. Recipients repay the original assistance plus 20% of the home's appreciation at sale or cash-out refinance, and those repayments recycle into future rounds. Governor Newsom directed that at least 10% of funding go to applicants in Qualified Census Tracts. It is genuinely transformative money, and it is also a lottery you can only enter during a two-and-a-half-week window each year.

MyHome is the workhorse. CalHFA's MyHome Assistance Program provides a deferred-payment junior loan of up to 3.5% of the purchase price or appraised value, whichever is less, usable for down payment or closing costs. It requires first-time buyer status, at least one borrower to complete a homebuyer education course and receive a certificate, and qualifying income under the county limit — which for Alameda County stands at $253,000 for 2026. That ceiling is high enough that a substantial share of East Bay households clear it, which surprises nearly everyone I mention it to.

Contra Costa County buyers have two additional avenues worth naming. Contra Costa County administers a Mortgage Credit Certificate program, authorized federally under the Tax Reform Act of 1984, which converts a portion of annual mortgage interest into a dollar-for-dollar federal tax credit for the life of the loan. And the Community Housing Development Corporation holds a State CalHome allocation providing 30-year deferred-payment second mortgages to qualified Contra Costa buyers. Neither is a down payment grant, but an MCC in particular improves your qualifying picture in a way that compounds every year you hold the home.

Program Comparison at a Glance

The Loan Limits That Quietly Decide Which Programs You Can Use

Does the price of the home affect which assistance programs I can use?
Yes, and more than most buyers expect. The Federal Housing Finance Agency set the 2026 baseline conforming loan limit at $832,750, with a high-cost ceiling of $1,249,125 that applies to Alameda County and the broader San Francisco–Oakland–Berkeley metro. Crossing from baseline into high-balance, or from high-balance into jumbo, changes your rate, your guidelines, and which assistance programs your first mortgage can pair with.

Here is the mechanical detail nobody explains. Most assistance programs are junior liens sitting behind a first mortgage, and they impose requirements on what that first mortgage can be. Past $832,750 you are in high-balance territory — slightly higher rates, tighter guidelines. Past $1,249,125 you are in jumbo territory, which sits outside the agency framework most assistance programs are built around.

The practical consequence for East Bay buyers is that a program stack which works beautifully at $750,000 may be unavailable at $1.3 million. That is not a reason to shop below your means. It is a reason to build the financing architecture before you build the search, because discovering the constraint after you have fallen in love with a house in Pleasanton is a bad afternoon. When I take on a buyer, sequencing the lender conversation ahead of the property tour is not a formality — it is the whole game.

One more line item that belongs in your cash-to-close calculation, and it is newer than most buyers realize. Following the National Association of REALTORS® settlement that took effect in August 2024, sellers are no longer required to offer buyer-agent compensation through the MLS. Buyer-agent compensation is now negotiated separately, and buyers must sign a written buyer representation agreement before touring homes with an agent. The California Department of Real Estate has long held that broker fees and commissions are fully negotiable and not set by law, and that principle now governs the buyer side explicitly. In practice, compensation is frequently still addressed as a term in the purchase offer — but it is a negotiated term, and if it is not covered by the seller, it becomes cash you need at closing. Any honest down payment plan in 2026 accounts for it.

How to Stack These Programs Without Losing the House

Can I combine multiple down payment assistance programs?
Often yes — a CalHFA first mortgage paired with MyHome, layered with a county program, is a common structure. But each program sets its own rules about subordinate financing, occupancy, and total assistance, and those rules govern. Stacking must be verified with your lender and each program administrator before you write an offer, never after.

Here is what I tell every buyer working with assistance money, because the failure mode is almost never eligibility — it is timing and presentation.

• Start with the program, not the property. Assistance programs run on their own calendars. Dream For All is an annual lottery. AC Boost operates on intake windows. If you find the house first, you have already lost access to whatever is not currently open.
• Get the homebuyer education certificate early. CalHFA requires at least one borrower to complete a homebuyer education course. It is a small step that becomes a two-week delay if you leave it until you are in contract.
• Use a lender who has actually closed these loans. Not one who says they can. Assistance programs have their own underwriting overlays and document sets, and a lender learning the program on your transaction is a genuine risk to your escrow timeline.
• Expect the listing side to ask questions. A seller comparing two offers will weigh certainty. An offer with a junior assistance lien invites scrutiny about closing timeline. That scrutiny is answerable — with a lender letter that names the program, a realistic timeline, and a listing agent who has been briefed before the offer arrives.
• Do not assume assistance makes you uncompetitive. In the current market, with rates near 6.7% and inventory conditions varying sharply between the Tri-Valley and the inner East Bay, a well-documented assisted offer competes. I have seen assisted buyers beat higher offers on certainty.

The uncomfortable truth is that these programs reward preparation and punish improvisation. The money is real, it is substantial, and it is sitting there — Alameda County voters approved Measure A1 specifically to put it into the hands of working households. But the buyers who capture it are the ones who built their financing plan in January for a house they bought in September.

Frequently Asked Questions

Do I have to be a first-time buyer to qualify?

For most of these programs, yes — but "first-time buyer" is a term of art, not a literal one. Under the standard federal definition that CalHFA and most county programs follow, you qualify if you have not owned and occupied your own home in the previous three years. That means a former homeowner who sold, divorced, or moved into a rental more than three years ago can requalify. AC Boost, administered by the Alameda County Housing and Community Development Department, applies first-time buyer status alongside its live-in, work-in, or displaced-from-Alameda-County connection requirement. Always confirm the specific definition with the individual program administrator, because a few programs vary it.

Does down payment assistance mean I will lose in a multiple-offer situation?

Not automatically. What loses offers is uncertainty, not the assistance itself. A listing agent evaluating competing offers is weighing the probability that your escrow closes on schedule. An assisted offer that arrives with a lender letter naming the specific program, a documented timeline, and a buyer's agent who has proactively called the listing agent reads as certain. The California Department of Real Estate frames the buyer's agent role around exactly this kind of advocacy. An assisted offer submitted with no explanation and a vague pre-qualification letter reads as risk — and that is what gets set aside.

What happens to a shared-appreciation loan if my home does not go up in value?

You repay the original assistance amount, and the appreciation share is calculated on appreciation that actually occurred. Under the California Housing Finance Agency's Dream For All structure, recipients repay the down payment amount plus 20% of the home's appreciation when they sell or take cash out in a refinance. If there is no appreciation, there is no appreciation share to pay. Note the reverse is also true: in a strongly appreciating market, the appreciation share can exceed what interest on a conventional second would have cost. This is a real tradeoff and worth modeling against your expected holding period with a tax advisor before you commit.

Should I look in Alameda County or Contra Costa County?

Run the numbers on both — they move differently and the gap is currently wide. Redfin's county data for the three months ending May 2026 showed an Alameda County median sale price near $1.2 million, up 5.4% year over year, against roughly $837,000 in Contra Costa County, up 2.1%. Because Home Access is capped at 40% of purchase price, the same program reaches proportionally further in Contra Costa. AC Boost, however, is Alameda-only. Local inventory and days-on-market data from the Bay East Association of REALTORS® frequently show the two counties diverging within the same month, so the right answer depends on your program stack and your price band, not on a general preference.

Can I use assistance money for closing costs instead of the down payment?

Sometimes, and it is worth asking specifically. CalHFA's MyHome Assistance Program is explicitly usable for down payment or closing costs, up to 3.5% of the purchase price or appraised value, whichever is less. Other programs restrict funds to the down payment only. This distinction matters more than it sounds, because in California — a non-attorney, escrow-closing state — buyer closing costs include escrow fees, title, recording, and prorated property taxes through the Alameda County or Contra Costa County Treasurer-Tax Collector, and those add up well beyond what buyers budget for.

How long does the process take with an assistance program?

Plan for longer than a conventional purchase, and build it into the offer. The California Residential Purchase Agreement runs a 17-day default inspection and appraisal contingency and 21 days for loan contingency, but a junior assistance lien adds a second underwriting track and a program administrator who has to sign off. In my experience the added time is manageable when the lender has closed the program before and is disclosed to the listing side up front. What is not manageable is discovering mid-escrow that a program requirement — a missing homebuyer education certificate, an occupancy affidavit — was never satisfied.

What to Do Next

If you are somewhere in this article, the next step is not browsing listings. It is finding out, precisely, which of these programs you qualify for and what your combined stack is actually worth — because that number determines your price band, and your price band determines where you look. That is a one-conversation problem, and I would rather have it with you in January than watch you miss a lottery window in March.

Send me your income picture and where you are looking, and I will map which programs you clear, what the stack is worth, and what the realistic cash-to-close is on a specific property type in a specific city. If you want to start with the basics, the buyer resources page covers the East Bay purchase process end to end, or you can reach out directly and we will start with the financing architecture instead of the house.
