The short answer: Proposition 37, on California's November 3, 2026 ballot, would let the California Housing Finance Agency (CalHFA) sell up to $25 billion in revenue bonds and lend middle-income buyers up to 17% of the price of a newly built home, with the buyer putting down at least 3%. Buyers would repay that loan monthly, and those payments repay the bonds, so the Legislative Analyst's Office estimates no direct state or local cost. Household income could be up to twice the area's typical income. The interest rate and loan term would be set by CalHFA later, so they are not known before the vote.
As of October 19, 2026. This article explains the measure; it does not recommend a vote.
What would Prop 37 actually do?
According to the Legislative Analyst's Office (LAO), Prop 37 would create a down payment program called the "middle-class homeownership loan." Here is how the pieces fit:
- Who runs it: CalHFA, the state's housing finance agency.
- Where the money comes from: CalHFA could sell up to $25 billion in revenue bonds. It decides how much to issue, and when. Revenue bonds are repaid from the program's own payments, not from the state's general fund.
- How big the loan is: up to 17% of the home price.
- What the buyer brings: a down payment of at least 3% of the price.
- How it's repaid: homeowners make monthly payments that repay the bond investors and cover administrative costs. The measure tells CalHFA to keep borrowers' interest costs as low as possible.
Together, 3% from the buyer plus up to 17% from the state reaches 20% down, which on a conventional loan generally means no private mortgage insurance. The rest would be a regular first mortgage from a private lender.
How a purchase could be structured under Prop 37 (share of price)
A hypothetical, for scale: on an $800,000 newly built home, the 3% minimum would be $24,000 (CalMatters' example). Under the measure's limits, the state loan could be up to $136,000 (17%). These are illustrations of the measure's percentages, not loan terms.
Who would qualify for a Prop 37 loan?
Based on the LAO analysis and CalMatters' guide:
- California residents who will live in the home.
- Household income up to twice the area's typical (median) income. That varies a lot by county. The California Budget & Policy Center gives two examples for a family of four: up to $166,800 in Madera County, and up to $375,800 in Santa Clara County.
- You must be the home's first buyer. Only newly built homes and condos qualify (the Budget Center notes units newly created by converting nonresidential buildings also count). Resale homes don't.
- Price limits apply. CalMatters describes the cap as about $1.5 million; the Budget Center says roughly $1 million to $1.5 million depending on county. Exact limits would be set under the program.
- You don't have to be a first-time buyer, and the state would not take a share of your home's appreciation, per the Budget Center.
Would this purchase fit Prop 37's basic rules?
| Eligible? | |
|---|---|
| New-construction home, first buyer, income under 2x area median | Yes if under the price limit |
| Resale home (someone lived there before) | No |
| Move-up buyer who already owns a home | Yes first-time status not required |
| Household income above 2x area median | No |
| Investor or second home | No must live in the home |
| Buyer moving to California from another state | Must be a California resident; program rules would define how |
How is this different from CalHFA's current down payment help?
CalHFA already offers down payment assistance, and the LAO notes those programs are loans that must be repaid. The key difference the California Budget & Policy Center highlights: CalHFA's existing programs are typically deferred "silent seconds," with no monthly payment until you sell or refinance. Prop 37's loan would likely be a fixed-rate second mortgage with monthly payments, which means it counts in your debt-to-income ratio when you qualify. The Budget Center also notes a borrower could ask for a temporary hardship deferral of interest payments.
What else would change for builders?
Any developer could build eligible homes. Builders could also opt into a "qualified builder" path that requires higher labor standards, such as workers with certain training. In exchange, those builders would be under different construction-defect rules that, per the LAO, "generally give developers more flexibility." If you buy a new home from a qualified builder, ask how defect claims and warranties would work before you sign.
Where does Prop 1, the housing bond, fit in?
Prop 1 is a separate measure. It would authorize $11.25 billion in state general obligation bonds for multifamily rental housing, mortgages for veterans, supportive housing, preserving existing affordable housing, and down payment assistance. Unlike Prop 37, it would be repaid from the state budget: the official estimate is $500 million to $600 million a year for about 25 years. No argument against Prop 1 was submitted for the voter guide. The two measures don't depend on each other; either, both or neither could pass.
What do supporters and critics say about Prop 37?
Supporters (including the California Association of Realtors, carpenters' unions, SEIU and the California Democratic Party, per CalMatters; former Assembly Speaker Robert Hertzberg is the primary sponsor) say a 20% down payment is out of reach for most families in a state where even a fixer-upper can cost $700,000, and that the program would put homeownership within reach "at no cost to taxpayers." They add that if a buyer defaults, private lenders, not taxpayers, would absorb the loss.
Opponents (including Reform California and the League of Women Voters, per CalMatters) argue the state shouldn't be in the mortgage business, that the measure doesn't address why California homes cost so much, and that it helps buyers mainly by adding more debt. The California Budget & Policy Center, which takes no position, raises other concerns: monthly payments on the second loan could eat into the benefit; the second loan's rate could be higher than the first mortgage's; limiting aid to new homes could push building farther from jobs; and new homes more often come with HOA dues, Mello-Roos assessments and harder-to-get insurance in wildfire areas.
For context on borrowing costs right now: Freddie Mac's national average for a 30-year fixed mortgage was 7.40% for the week of October 15, 2026, unchanged from the week before and up from 6.27% a year earlier. That is a national average for borrowers with 20% down and excellent credit, not a quote, but it shows why the eventual rate on the Prop 37 loan would matter so much.
If I'm planning to buy, what should I do before and after November 3?
- Don't hold off on a good home just for the vote. Even if it passes, CalHFA would still need to issue bonds and set rates, terms and price limits before loans are available, and the LAO lists investor interest in the bonds as an uncertainty.
- Compare the total monthly picture, not just the down payment. A smaller first mortgage plus a second loan with its own payment can come out ahead or behind a single loan with mortgage insurance; it depends on rates that aren't set yet.
- Family help is still an option. If parents want to help instead, I explain gifts, co-signing and co-borrowing in Helping Your Adult Child Buy a Home.
Outside California? Prop 37 only applies to California homes and California residents. If you're relocating, or helping a child buy here, talk with a California lender early about how residency would be shown once program rules exist.
Derek\'s take
After 20 years and more than 1,200 loans in California, I know the down payment is where most good buyers get stuck, so any program aimed at that gets my attention. How you vote on Prop 37 is your call, and I won't tell you which way to go. What I can tell you is that the details that decide whether a program like this helps a particular family (the rate, the term, the monthly payment on the second loan) would come later from CalHFA, and they'd be worth a careful side-by-side comparison. If you're thinking about buying in the next year and want to map out your options either way, book a call with me. Thirty minutes, no credit pull, no obligation.
Frequently asked questions
When is the vote on Prop 37?
Tuesday, November 3, 2026, in California's statewide general election. As a statute, it passes with a simple majority.
Would Prop 37 cost taxpayers money?
The Legislative Analyst's Office estimates no direct state or local costs, because borrowers' payments repay the bond investors. It notes uncertainty about investor demand for the bonds and how attractive the loans would be compared with other options.
Can I use Prop 37 to buy a resale home?
No. It applies only to newly built homes (and certain newly converted units) where you are the first buyer.
What interest rate would the Prop 37 loan have?
It isn't known. CalHFA would set the rate and terms after the vote, and the measure directs it to keep borrowers' interest costs as low as possible.
Is Prop 37 the same as Prop 1?
No. Prop 1 is an $11.25 billion general obligation bond for several housing programs, repaid from the state budget. Prop 37 is a self-funded loan program for buyers of new homes. They are separate votes.
