First-Time Homebuyer Programs in San Diego

Key takeaways

• CalHFA (the state housing finance agency) offers two things: first-mortgage products (CalPLUS FHA and CalPLUS Conventional) and down-payment/closing-cost assistance layered on top (MyHome Assistance Program, the Zero Interest Program). Verify current rates and assistance caps at calhfa.ca.gov before assuming a figure you saw elsewhere still applies.
• Dream For All, CalHFA's shared-appreciation down-payment program, does not run continuously — it opens for a limited application window when funded, then closes once that round's money is allocated. As of this research (July 2026), the most recent registration window ran February 24 through March 16, 2026, and CalHFA has not announced a new open window since. Confirm live status at calhfa.ca.gov/dream before telling a client or yourself it is available.
• The Mortgage Credit Certificate (MCC) is not a grant or a loan — it is a federal tax credit that lets a qualifying buyer claim a percentage of the mortgage interest paid each year as a direct credit against federal income tax, for as long as they hold the loan and live in the home. It is administered locally (in San Diego, through SDHC and jurisdiction-specific programs), and the credit rate and program availability are set by the administering agency, not fixed nationally.
• San Diego Housing Commission (SDHC) runs first-time buyer assistance for both the City of San Diego and, under a separate agreement, for the County of San Diego and several other cities. Income tier, assistance structure, and even whether a given tier currently has funding all vary — SDHC's own materials note that some tiers can run out of allocated funds while others remain open. Check sdhc.org/housing-opportunities/first-time-homebuyers for the current funding status of each tier.
• The County of San Diego's Downpayment and Closing Cost Assistance (DCCA) Program — sometimes referenced by its older name, HDCCAP — is county-funded but SDHC-administered, aimed at low- and moderate-income first-time buyers in the unincorporated county and participating cities. Structure (percentage of purchase price, interest terms) is published by the county and by SDHC; confirm current numbers directly rather than from a third-party summary.
• GSFA Platinum and similar privately marketed down-payment-assistance programs are real and statewide, not San Diego-specific, and they frequently run limited-time promotional structures (expanded eligibility, grant vs. repayable-loan mix) that expire on a stated date. Verify at gsfahome.org which structure is currently active.
• USDA Rural Development loans have limited relevance in San Diego County: eligibility is address-specific and generally confined to the unincorporated, lower-density fringe (parts of the backcountry and foothills), not the incorporated cities where most buyers are shopping. Check any specific address against the USDA's own eligibility tool rather than assuming a neighborhood qualifies.
• Nearly every program here shares two structural requirements: a first-time-buyer definition (generally no ownership interest in a primary residence in the prior three years, though the exact rule is set by each program) and a HUD- or CalHFA-approved homebuyer-education course. Income limits are set by AMI, which HUD and the state update at least annually, so an income limit you read six months ago may already be out of date.

CalHFA: first mortgages and down-payment assistance

CalHFA is the state's affordable-housing lender, and its role is best understood as two separate layers that snap together.

The first mortgage. CalHFA's government-loan first mortgage (CalPLUS FHA, and its variant CalPLUS Access FHA) is an FHA-insured 30-year fixed loan, typically priced at a modestly higher rate than a standard FHA loan in exchange for the ability to pair it with CalHFA's own assistance products. CalHFA Conventional (and CalPLUS Conventional) is the equivalent structure for a conventional first mortgage with private mortgage insurance. These are underwritten like any FHA or conventional loan — same property eligibility, same core qualifying rules — with CalHFA as the funding source and a CalHFA-approved lender originating the file.

The assistance layer. The MyHome Assistance Program is a deferred-payment, silent-second loan used for down payment and/or closing costs, sized as a percentage of the purchase price or appraised value (the government-loan and conventional versions have historically carried different caps). It accrues simple interest and is not due until the borrower sells, refinances, or pays off the first mortgage — there are no monthly payments on the MyHome loan itself. The Zero Interest Program (ZIP) is a separate deferred second, usable only with a CalPLUS first mortgage, dedicated specifically to closing costs, and — as its name states — carries no interest.

Both the percentage caps and the ZIP structure are program parameters CalHFA can and does revise. Do not rely on a percentage figure from a blog post or a prior version of this guide — pull the current MyHome and ZIP terms straight from calhfa.ca.gov/homebuyer/programs/myhome.htm before quoting a number to a buyer.

Dream For All: shared appreciation, not a standing program

Dream For All is CalHFA's shared-appreciation down-payment loan for first-generation, first-time homebuyers, paired with a CalHFA Conventional first mortgage. The mechanism: CalHFA funds a portion of the down payment (structured as a percentage of the purchase price or appraised value, up to a stated program cap), and when the home is later sold, refinanced, or transferred, the borrower repays the original assistance plus a share of any appreciation in the home's value. If the home has appreciated, CalHFA's share grows with it; if it hasn't, the repayment obligation does not exceed what current program rules specify. That structure — assistance tied to a future share of upside — is what distinguishes it from a standard deferred second like MyHome.

Dream For All is not continuously open. It has run in discrete rounds since its 2023 launch: each round opens a registration window, demand has consistently exceeded available funding, CalHFA has used randomized selection among registrants, and the window closes once allocated funding is spoken for. The most recent round registered applicants from February 24 through March 16, 2026. Whether and when a new round opens depends on new state funding being appropriated and CalHFA scheduling another window — information that changes without much lead time. Before telling anyone Dream For All is “available,” check the live status page at calhfa.ca.gov/dream — it will show whether registration is open, closed, or upcoming, and link the current program handbook for the assistance percentage and cap actually in force.

Mortgage Credit Certificate (MCC): a tax credit, not a loan

An MCC is fundamentally different from every other program in this guide: it does not put money toward the purchase or closing. It converts a slice of the mortgage interest a qualifying buyer already pays into a direct, dollar-for-dollar federal income tax credit, claimed annually for as long as the buyer holds that mortgage and occupies the home as a primary residence (the remaining mortgage interest not converted to a credit is still deductible as an itemized deduction, subject to normal tax rules). The credit rate — the percentage of annual mortgage interest converted to a credit — is set by the issuing agency and its bond authority, not by federal statute directly, and can vary by jurisdiction and by program vintage.

In San Diego County, MCC programs have historically been administered locally — through SDHC for the City of San Diego, and through separate arrangements covering other incorporated cities and the unincorporated county — rather than run as one countywide program with one rate. Because MCC allocations are tied to mortgage-revenue-bond authority that can be exhausted and reissued, the honest state of play is: confirm with SDHC or your lender whether an MCC is currently being issued in the specific jurisdiction where you're buying, and at what credit rate, rather than assuming a rate quoted here or anywhere else still holds. A homebuyer generally cannot combine an MCC with certain other CalHFA subsidized-rate first mortgages in the same transaction — check compatibility with your loan officer before assuming you can stack it with everything else in this guide.

San Diego Housing Commission (SDHC) first-time buyer programs

SDHC is the closest thing San Diego has to a one-stop shop for local down-payment assistance, because it administers programs on behalf of both the City of San Diego and, under a separate agreement, the County of San Diego and other participating jurisdictions. The mechanics are broadly consistent across tiers — a deferred-payment second loan for down payment, sized as a percentage of purchase price, plus a separate closing-cost grant, gated by an area-median-income tier — but the specific percentages, dollar caps, interest rates, and deferral terms differ by tier and have changed over time as SDHC has adjusted the program to available funding.

Two things matter more than any single number here. First, not every tier is funded at the same time — SDHC's own program materials have, at points, shown a lower-income tier fully allocated (no new applications being accepted) while a moderate-income tier remains open, or vice versa. Second, every tier requires working through an SDHC-approved participating lender and completing a HUD- or SDHC-approved homebuyer-education course before closing — this is not optional paperwork, it's a qualifying condition. Confirm which tiers are currently funded, their income limits (which move with each year's AMI update), and their current assistance structure at sdhc.org/housing-opportunities/first-time-homebuyers, or by calling SDHC's homeownership line directly.

County of San Diego: Downpayment and Closing Cost Assistance (DCCA / HDCCAP)

The County of San Diego funds its own first-time-buyer assistance program, administered on the county's behalf by SDHC, aimed at low- and moderate-income buyers purchasing in the unincorporated county and participating cities. Structurally it mirrors SDHC's city-side programs: a deferred-payment, low-interest second loan for down payment sized as a percentage of the purchase price, plus a separate closing-cost assistance component, with the loan not due until the borrower sells, refinances, or stops occupying the home. The county has, at points, run separate income tiers (a lower-income tier and a newer moderate-income tier added as of 2026), each with its own percentage cap and interest terms — and those tiers have been revised as the county reallocates funding.

The requirements that carry across nearly every version of this program: the buyer contributes a minimum share of the purchase price from their own funds (assistance is not typically structured as 100% financing), household income must fall under the applicable AMI limit for the tier, the buyer must not have owned a home in the prior three years, and a HUD/CalHome-approved homebuyer-education class is required. Because this is a county-appropriated, SDHC-administered program with two tiers that don't always move in sync, verify current eligibility percentages and funding status directly with the county or SDHC rather than from a secondary summary — sources below link both the county's program page and SDHC's published guidelines, but treat both as a starting point for a phone call, not a final number.

GSFA Platinum and similar privately marketed DPA programs

GSFA Platinum (Golden State Finance Authority) is a statewide — not San Diego-specific — down-payment and closing-cost assistance program that a participating lender can layer onto an FHA, VA, USDA, or conventional first mortgage. Unlike the public-agency programs above, it is marketed aggressively through loan officers and mortgage-content sites, which is exactly why it deserves the same “verify before quoting” treatment: GSFA has run limited-time promotional structures — for example, a period where assistance was offered partly as a non-repayable grant rather than purely as a repayable second mortgage, available to a broader pool of buyers than the standard occupation-restricted version — with a stated expiration date after which the terms revert. Whether a promotional structure is currently active, and what the standard fallback terms are, needs to be confirmed at gsfahome.org/programs/dpa/platinum.shtml or with a participating lender, not assumed from an article dated even a few months back.

Other privately administered DPA programs (various nonprofit and lender-sponsored grant products) exist alongside GSFA and rotate in and out of the local market; the same rule applies to all of them — confirm the current issuing entity, funding status, and whether the assistance is a grant, a deferred loan, or a repayable second before counting on it.

USDA rural loans: real, but narrow in San Diego County

USDA Rural Development's guaranteed loan program (0% down, income-limited, available for owner-occupied purchases in USDA-designated rural areas) technically operates in San Diego County, but its footprint here is genuinely limited. USDA eligibility is drawn on a property-by-property map that generally excludes the incorporated cities and their denser surrounding areas — meaning most of the county's population centers, where most first-time buyers are shopping, fall outside eligible territory. The areas that do qualify tend to be the county's less-populated backcountry and foothill communities.

Because eligibility is address-specific and the map itself gets periodically redrawn, the only reliable check is the USDA's own property eligibility lookup at eligibility.sc.egov.usda.gov — enter the specific address rather than assuming a general area of the county is or isn't eligible.

How these stack with your first mortgage

None of the down-payment and closing-cost programs above are first mortgages on their own — they're layered on top of an FHA, VA, or conventional first mortgage, and (with the partial exception of USDA, which is its own loan type) they exist specifically to reduce what a buyer needs in cash at closing. A few rules of thumb apply across nearly all of them:

• The first-time-buyer definition is not universal, but it is common. Most of the programs above define “first-time buyer” as not having held ownership interest in a primary residence in the prior three years — which is why a buyer who owned a home a decade ago but hasn't since can often still qualify. Confirm the exact definition with each specific program, since a few carve out exceptions (e.g., displaced homemakers, buyers in federally designated target areas).
• Income limits are set by AMI and change at least annually. HUD and the state publish updated area median income figures on a regular cycle, and every income-gated program above resets its qualifying limits when that happens. A limit that was accurate when a guide was written can be stale within months.
• Homebuyer education is a near-universal requirement, not a suggestion — CalHFA, SDHC, and the County program all require a HUD- or CalHFA-approved course before closing.
• Assistance can reduce cash to close without changing the underlying loan program's qualifying math — a MyHome or SDHC second loan still requires the buyer to qualify for the first mortgage on its own terms (debt-to-income ratio, credit, reserves), and the assistance loan's payment (if any) can itself count against DTI depending on the program's deferral structure. Run the math on the actual combination with your lender rather than assuming assistance is “free” headroom.
• Programs are not always stackable with each other. An MCC, for instance, can be incompatible with certain CalHFA subsidized first-mortgage products in the same transaction. Confirm compatibility for your specific combination before assuming you can layer every program in this guide onto one purchase.

For the underlying financing math these programs sit on top of — how FHA, VA, and conventional first mortgages actually compare on payment and cash-to-close in San Diego County — see the income-to-buy-a-$1M-home guide, the FHA loans in San Diego guide, the VA loans in San Diego guide, and the closing costs in San Diego guide.

Common questions

Is Dream For All available right now?

Not continuously. It opens for a defined registration window when CalHFA has new funding, and closes once that round is allocated. The most recent window ran February 24 through March 16, 2026; check calhfa.ca.gov/dream for the current status before assuming it's open.

Do I have to be a first-generation homebuyer to use any San Diego program?

No — that requirement is specific to Dream For All. CalHFA's MyHome, SDHC's programs, and the County's DCCA program use a standard first-time-buyer definition (generally no ownership in the prior three years), not a first-generation test.

Can I combine SDHC assistance with an MCC?

Potentially, but compatibility depends on the specific first-mortgage product and current program rules — some CalHFA subsidized-rate loans are not MCC-compatible. Confirm with your lender before assuming a combination works.

Does USDA financing work anywhere in San Diego County?

In limited areas only — mostly unincorporated backcountry and foothill communities outside the incorporated cities. Eligibility is address-specific; check the exact property against the USDA's eligibility map rather than assuming by region.

Why won't this guide just tell me the current down-payment assistance percentage?

Because these percentages, income limits, and funding windows change — sometimes within the same year — and a stale figure printed as fact is more likely to mislead a buyer than a pointer to the live source. Every program section above links the page to check.
