California voters weigh Proposition 37, which would authorize the California Housing Finance Agency to issue up to $25 billion in revenue bonds for second mortgages covering as much as 17 percent of the purchase price on qualifying new homes for buyers earning at or below 200 percent of area median income. The closely balanced 54 percent Yes implied probability reflects modest early polling support near 53 percent alongside historical patterns where citizen initiatives often face rejection, with stronger backing among renters and potential homeowners offset by lower enthusiasm from existing homeowners who turn out at higher rates. Recent voter guides and labor union endorsements have sustained momentum, while limited organized opposition and the self-repaying bond structure keep the contest tight. Final campaign spending, turnout differentials, and any late shifts in housing market sentiment could decide passage before the November 3 election.
