Peninsula buyers navigating Northern California real estate received two major policy shifts at the ballot box this November. California voters approved a pair of housing measures designed to lower upfront financial barriers for prospective homeowners: Californians vote a resounding 'yes' on housing affordability propositions. The two measures, Proposition 1 and Proposition 37, attack housing affordability through distinct financial mechanisms. For residents targeting Daly City, South San Francisco, and the broader San Mateo County corridor, the new programs offer substantial down payment relief, but they also introduce distinct borrowing rules that require careful preparation before lenders open their applications.
How Prop 37 structures second mortgages for newly built homes
Proposition 37 establishes a state-administered financing initiative managed by the California Housing Finance Agency (CalHFA). Rather than offering outright grants or traditional shared-equity pools, the program provides qualifying buyers with a fixed-rate second mortgage covering up to 17% of the purchase price on newly constructed homes. When paired with a borrower down payment of just 3%, the combined equity reaches 20%. This 20% equity threshold immediately eliminates the need for private mortgage insurance (PMI), which typically adds hundreds of dollars to monthly carrying costs for high-balance loans.The financial parameters of Prop 37 reflect the high baseline valuations found across the Peninsula. In San Mateo County, homes priced up to roughly $1.56 million qualify for the program, with household income eligibility capped at around $400,000 for a family of four. A key structural benefit is that participation does not require first-time homebuyer status. Repeat buyers relocating from older properties or expanding into larger footprints can access the loan, provided they meet income caps and purchase qualifying new residential construction.Consider how this plays out on the ground in Daly City. A newly built three-bedroom townhome near John Daly Boulevard or along the Mission Street transit corridor priced at $1.4 million traditionally requires a 20% down payment of $280,000 to bypass private mortgage insurance. Under Prop 37, an eligible household provides a 3% cash contribution of $42,000, while CalHFA provides a 17% junior loan of $238,000. That structure lowers the initial liquid cash barrier by $238,000. However, the junior lien is not deferred debt or a forgiveable grant: it carries its own monthly principal and interest payment that your primary lender will evaluate against your gross monthly income.Where Prop 1 directs $11.25 billion across affordable resale housing
While Proposition 37 focuses exclusively on expanding consumer purchasing power for brand-new housing stock, Proposition 1 targets the broader inventory framework by authorizing $11.25 billion in state general obligation bonds for affordable housing creation and preservation. A significant portion of this bond allocation funds targeted down payment assistance programs aimed directly at low- and moderate-income purchasers. Unlike Prop 37, these funds are reported to assist buyers purchasing existing resale homes, including older condominium units that make up an essential segment of starter-home supply across northern San Mateo County.Resale inventory represents the vast majority of transactions in established neighborhoods like Westlake, St. Francis Heights, and Serramonte. Condominiums off Gellert Boulevard or garden-style complexes along Hickey Boulevard offer entry pricing substantially below new construction townhomes, often trading between $600,000 and $850,000. Prop 1 assistance enables buyers who cannot afford new-construction pricing to secure down payment support on these established properties, making entry into the Peninsula market viable without competing against developer spec pricing.Which details first-generation homebuyers should watch
For first-generation homebuyers who lack family equity transfers or generational wealth to draw upon, the mechanics behind these state programs demand rigorous scrutiny. The prospect of buying a Daly City home with 3% out of pocket is appealing, but stacked debt instruments carry specific risks that must be factored into your financial planning before you submit an offer.Underwriting standards for a two-loan structure differ significantly from single-lien conventional financing. First-generation purchasers should monitor four critical technical elements before committing their savings:- Total debt-to-income (DTI) calculations: Lenders must factor the monthly payment of the 17% CalHFA second mortgage into your back-end DTI ratio alongside your primary mortgage, property taxes, homeowner association dues, and hazard insurance.
- Homeowner Association (HOA) budget health: Most newly constructed developments in Daly City operate under an HOA, with monthly dues often running between $350 and $600. Lenders will decline your loan if the association reserves fall short of Fannie Mae or CalHFA standards, regardless of your personal credit score.
- Supplemental property tax bills: In San Mateo County, the base 1% ad valorem tax rate combines with voter-approved local bond measures to reach roughly 1.15% to 1.25% of the purchase price. A newly assessed $1.4 million home yields an annual tax bill topping $16,000, requiring significant monthly escrow reserves.
- Subordination restrictions during future refinances: Second liens held by public agencies frequently carry strict subordination clauses. If interest rates drop in two or three years and you seek to refinance your primary mortgage, CalHFA must formally approve keeping their second mortgage in junior position.
