California voters have approved a $25 billion homebuyer financing initiative that could create new purchase mortgage opportunities for lenders and brokers, particularly those working with homebuilders.
Proposition 37, which passed with more than 60% of the vote in the Nov. 3 election, authorizes the California Housing Finance Agency (CalHFA) to issue up to $25 billion in revenue bonds to fund fixed-rate second mortgages covering as much as 17% of the purchase price of qualifying newly constructed homes.
Combined with a traditional first mortgage, the program could allow eligible buyers to purchase a home with as little as 3% of their own money down.
But the assistance comes with an important distinction: It's a loan, not a grant. Borrowers must repay the second mortgage, and the cost of that additional debt will help determine how many buyers can qualify.
How The Program Works
Under the official ballot measure, eligible borrowers must be California residents, intend to occupy the property as their primary residence, and have household incomes no greater than 200% of the area's median income.
The program is not limited to first-time homebuyers, although the property must be newly constructed or a qualifying residential conversion. Existing resale homes are excluded.
Purchase-price limits also apply, generally restricting eligible properties to homes priced below approximately $1 million to $1.5 million, depending on location.
On a $900,000 home, for example, a buyer could contribute $27,000, or 3%, while a $153,000 second mortgage covers another 17%. A traditional first mortgage would finance the remaining $720,000.
That structure could reduce the cash needed at closing while keeping the first mortgage at 80% loan-to-value, potentially eliminating the need for conventional private mortgage insurance.
That introduces another financing option for buyers who have sufficient income to support homeownership but struggle to accumulate a substantial down payment.
The Affordability Question
California's down payment problem is well documented.
As NMP previously reported, a July affordability analysis found that California households needed more than twice the state's median household income to afford a typical home. Saving a traditional 20% down payment could take the typical household more than 14 years.
Proposition 37 addresses that upfront hurdle, but it doesn't eliminate the monthly affordability challenge.
An August analysis by the California Budget & Policy Center found that the cost of repaying a second mortgage could offset some of the savings from avoiding mortgage insurance.
The financing structure also depends on private investors purchasing the bonds. Because second mortgages carry greater repayment risk than first liens, investor expectations could influence the interest rates ultimately offered to borrowers.
According to CalMatters, Proposition 37 proponent Robert Hertzberg has approached potential investors about purchasing the bonds at below-market rates, an effort that could help reduce borrowing costs if investors participate.
The state's Legislative Analyst's Office has identified investor demand and the cost of the loans compared with existing assistance programs as key factors affecting the measure's impact.
A New Opportunity for Purchase Lenders
Unlike many down payment assistance programs, Proposition 37 is tied specifically to newly constructed homes and qualifying conversions.
That puts homebuilders and their mortgage lending partners in a potentially advantageous position.
Builders with eligible properties could reach buyers previously sidelined by down payment requirements. Lenders already active in new construction financing may also be well positioned to incorporate the assistance into their purchase offerings.
Independent brokers could benefit as well, particularly those with builder relationships and access to participating wholesale lenders.
The measure also includes a separate provision allowing builders that meet specified labor standards to operate under modified construction-defect rules. Participation in that arrangement is voluntary and is not required for a builder's homes to qualify for the financing program.
How Many Buyers Could Benefit?
The California Association of Realtors (CAR), a leading supporter of the measure, estimates the program could eventually provide homeownership opportunities for approximately 926,000 households.
"The CALIFORNIA ASSOCIATION OF REALTORS® is proud to have been a leading supporter of Proposition 37, which will bring the dream of homeownership within reach for more middle-class Californians," said 2026 C.A.R. President Tamara Suminski.
The association says the program could be particularly beneficial to teachers, nurses, firefighters, and other middle-income workers struggling to purchase homes in the communities where they work.
The projected number of beneficiaries depends on how the bond proceeds are deployed and recycled as borrowers repay their loans.
Independent research has also highlighted the gap between meeting the program's income limits and being able to afford a qualifying home. The Public Policy Institute of California found that while many renters could meet the income requirements, fewer would have sufficient earnings to afford a newly built home.
What Comes Next for Lenders
The $25 billion represents borrowing authority, not funding already available for mortgages.
CalHFA must establish the program and determine how much debt to issue, along with the loan terms and procedures for delivering the financing.
For California lenders and brokers, the details that matter most will be the cost of the second mortgage, compatibility with existing first-mortgage products, and access for participating originators.
The initiative could provide another way to serve buyers who can afford a mortgage but haven't accumulated enough cash to purchase a home.
Its impact on California's purchase market will depend on how competitively those loans are priced and how many eligible buyers can qualify.
