Should California use $25 billion in bonds to fund down payment loans for new homes?

Proposition 37 appears on California's November ballot and would allow the state's Housing Finance Agency to borrow up to $25 billion to fund low-interest down payment loans. The loans would cover 17% of a home's value for eligible buyers of newly constructed homes.

Why it matters

Supporters say the program could open homeownership to buyers who cannot afford a down payment, while critics argue it will not solve overall home affordability. Proponents expect the funding to stimulate construction, and one economist warns it could push prices higher.

The measure would allow the Housing Finance Agency to borrow up to $25 billion, with loans covering 17% of a home's value so buyers pay about 3% upfront. Eligible buyers can earn no more than twice their area's median income, which in San Luis Obispo means $147,000 per year, and the program is not restricted to first-time buyers.

The details

Proposition 37 would fund low-interest loans through state revenue bonds sold to private investors, which are repaid by assisted homebuyers. The proposition does not raise taxes, and the home must be newly built to qualify.

Market Landscape

Proposition 37 extends California's Housing Finance Agency bond-funded lending model into down payment assistance for newly built homes. Its effect on prices depends on whether added buyer demand outpaces the new construction it is meant to encourage.

Buyers would need to purchase a newly built home and fall under the income limit of twice the area median income, such as $147,000 in San Luis Obispo, to qualify. The program's loans would cover most of the down payment, leaving buyers to pay only 3% upfront if the measure passes in November.

The takeaway

Prospective buyers of new construction in California should check income limits and eligibility before the November vote. Those who might otherwise be shut out by the down payment should watch how the program is implemented.
