California Proposition 37 and Your Next Home

California Proposition 37 could help eligible buyers cover part of a new home’s purchase price through an additional loan. Voters will decide the measure on November 3, 2026. For anyone planning a move, the immediate question is how the proposed financing would fit the home, the budget and the timing. ^[1]

Across Upland, Claremont, the San Gabriel Valley and the Inland Empire, a property decision often reaches beyond the purchase itself. It may involve keeping an existing home, preserving savings or coordinating a sale and a move. A ballot proposal belongs in that discussion, with its limits clearly understood.

What Proposition 37 would do

The measure would authorize the California Housing Finance Agency, or CalHFA, to issue up to $25 billion in revenue bonds for a new homebuyer program. Eligible buyers could receive a fixed-rate second mortgage covering up to 17% of the purchase price and would contribute at least 3% themselves. Borrowers’ repayments would fund repayment of the bonds. The assistance would be debt that must be repaid. ^{[1] [3]}

Who and what could qualify

The proposed law sets these requirements, among others: ^[2]

• California residency for at least one year before applying.
• Occupancy as a primary residence within 60 days of closing.
• Family income at or below 200% of the applicable area median, adjusted for family size.
• A minimum 3% contribution from funds other than a grant or borrowed money.
• The first purchase of a qualifying newly built home or a qualifying residential conversion of a nonresidential building.

The price ceiling would be 125% of the county’s conforming loan limit for a one-unit property. That makes the county and year relevant; the same advertised price would not establish eligibility everywhere. ^[2]

An illustrative home purchase

Assume an $800,000 home qualifies and both loans are approved at the maximum assistance level:

The buyer would still borrow $776,000, or 97% of the price. The practical benefit would be less cash required toward the purchase, accompanied by a second loan obligation. This illustration excludes closing costs and does not quote an interest rate or monthly payment.

A useful lender comparison would show the combined loan payments, taxes, insurance, any HOA charges, cash needed at closing and reserves remaining afterward. The down payment alone cannot tell you whether a home fits your budget.

What this could mean for your property decision

For a buyer, start with the property type. A new townhome and an existing detached house may present very different financing options under this proposal. Ask for a comparison using actual properties and current loan choices, then revisit it if the program becomes available.

For a seller, watch whether nearby new construction becomes a more competitive alternative for your likely buyers. That is a market scenario to evaluate, not a prediction that the measure will raise or lower your sale price. Your own pricing decision still needs recent comparable sales, competing listings and the condition of your property.

For an owner considering a move, compare the entire change in housing costs. Selling, staying or adapting your current home may each deserve a place in the conversation. Preserve flexibility until you have dependable financing and transaction dates.

Timing matters. The proposed law directs CalHFA to implement the program within one year after its effective date. Passage would not mean a loan is ready for your next escrow. ^[2]

There is also a builder provision: an optional arrangement would pair higher labor standards with different construction-defect rules. If considering a participating builder’s home, ask which rules and disclosures would apply. The official analysis identifies uncertainty about investor demand, borrowing costs and the program’s eventual scale. ^[3]

How Proposition 40 is different

Proposition 40 is a separate billionaire wealth-tax proposal. It would impose a one-time tax of up to 5% on covered net worth, with a phase-in for individuals below $1.1 billion and provisions covering certain trusts. Its residency reference date is January 1, 2026; its valuation date is December 31, 2026. Payment would generally be due in 2027. ^{[4] [5]}

The proposed text excludes real estate held directly or through a revocable trust from net worth. Interests held through businesses or other structures require separate analysis. It would not create a general 5% tax on ordinary home sales. Anyone potentially subject to the measure should take ownership and residency questions to a qualified tax adviser. ^[5]

The Legislative Analyst projects a temporary revenue increase and a possible ongoing reduction in income-tax receipts, while emphasizing uncertainty. The official guide also warns that Propositions 41 or 42 could prevent Proposition 40 from taking effect if they receive more yes votes and courts find a conflict. ^[4]

For local real estate, broader economic effects remain a scenario to monitor. They do not establish that a specific Claremont home will lose value or that an Inland Empire buyer should rush into a purchase. Local transaction evidence is the sounder starting point for those decisions.
