Proposition 37 would authorize up to $25 billion in bonds to support fixed-rate mortgages covering up to 17% of the purchase price of qualifying new homes. Eligibility includes California residency, owner occupancy, income below 200% of area median income, and at least a 3% down payment. Qualifying homes generally must be new construction or qualifying conversions and fall below county-dependent price limits. The proposal says homeowner mortgage payments, rather than ordinary state revenues, would repay the bonds. The debate is whether subsidizing purchasing power will expand ownership or mainly increase demand in an already supply-constrained market. A family can earn too much for traditional housing aid and still have no realistic path to a California down payment. Buyer assistance helps only if it expands access to homes instead of simply giving buyers more money to compete over too few houses.
