The gap between "I want to buy" and "I have enough cash for a down payment" is the single biggest thing keeping Bay Area buyers on the sidelines. What a lot of people don't realize is how much real assistance actually exists, at the state level and right here in San Mateo County, to help close that gap.
Quick note: program details, funding availability, and eligibility rules change, sometimes year to year. This is an overview to help you know what to ask about. Always confirm current terms with a participating lender or housing counselor before making plans around a specific program.
The state-level programs (CalHFA)
The California Housing Finance Agency runs several programs that pair with your first mortgage, rather than replacing it:
- MyHome Assistance Program: a deferred-payment loan (no monthly payments) of up to 3.5% of the purchase price for FHA loans, or 3% for conventional, to help with your down payment or closing costs.
- ZIP (Zero Interest Program): zero-interest help specifically for closing costs, typically 2-3% of the loan amount, paired with MyHome.
- MyAccess: a deferred second loan of up to 2.5%, generally used alongside FHA financing.
- Dream For All: a shared-appreciation loan that can cover up to 20% of the purchase price (capped at $150,000), specifically for first-generation home buyers. This one runs in limited application windows rather than staying open year-round, so timing matters if it interests you.
These deferred loans generally aren't forgiven. You repay them (often along with a share of appreciation, depending on the program) when you sell, refinance, or pay off your first mortgage. Income limits are set by county, and Bay Area counties have higher limits than most of the state given local housing costs.
Local help right here in San Mateo County
This is the part most buyers never hear about. San Mateo County has its own local resources beyond the statewide programs:
- HEART of San Mateo County (Housing Endowment and Regional Trust): a local nonprofit offering below-market down payment assistance loans, often paired with a partner lender. Assistance amounts vary by city and household situation.
- City of San Mateo First-Time Home Buyer Program: offers a range of loan programs, with priority given to applicants who live or work in the City of San Mateo.
- SAMCAR + HEART closing cost partnership: a local collaboration that has offered up to $5,000 in closing cost assistance for first-time buyers in the county.
- County of San Mateo Department of Housing: maintains a current list of first-time homebuyer programs available countywide, worth checking directly since offerings shift over time.
What actually disqualifies most buyers
It's usually not the down payment itself, it's debt-to-income. Assistance programs solve the cash-at-closing problem, not the monthly-payment problem. Even with full assistance covering your down payment, your income still needs to support the mortgage payment itself under the lender's debt-to-income limits.
How to actually use these
Most programs require a HUD-approved homebuyer education course, and you'll need a lender who's specifically approved to originate CalHFA-backed loans, not every lender offers these. Local funds can be limited and move on a first-come basis, so identifying your options and getting pre-qualified with a participating lender early matters more than almost anything else in this process.

I can't give you tax or lending advice, but I can help you understand which of these programs might realistically fit your situation, and connect you with lenders in San Mateo County who work with them regularly.
