The Prop 37 home loan, explained plainly
California voters approved a state loan that can cover up to 17 percent of a newly built home, so a buyer can put down as little as 3 percent. Here's who it's for, what it could cost and what nobody knows yet.
- 3% your own money, the minimum
- Up to 17% Prop 37 second mortgage
- The rest on a regular first mortgage
What the Prop 37 home loan is
Proposition 37 is a California ballot measure called the California Middle-Class Homeownership and Family Home Construction Act of 2026. It was on the November 3, 2026 ballot. CBS News projected it would pass, and early returns showed about 61 percent in favor. The Secretary of State still has to certify the count.
The measure lets the California Housing Finance Agency, known as CalHFA, sell up to $25 billion in revenue bonds and use the money for a new program called the "middle-class homeownership loan." According to the Legislative Analyst's Office, each loan can cover up to 17 percent of the home price.
In one sentence: it's a state second mortgage on a newly built home that replaces most of a 20 percent down payment, and you pay it back.
It is a loan, not a grant. The official argument for the measure says it plainly: buyers must "make monthly payments, and fully repay their loans." That repayment is what pays back the bond investors, which is why the Legislative Analyst found no direct cost to state or local government.
How the loan works
A buyer would use three pieces of money. You put in at least 3 percent yourself. The Prop 37 loan covers up to 17 percent as a second mortgage. A regular first mortgage from a lender covers the rest, which is usually 80 percent.
That adds up to 20 percent in front of the first mortgage. The California Budget & Policy Center notes this avoids private mortgage insurance. On an $800,000 home, CalMatters calculated the cash down payment falls from about $160,000 to about $24,000.
The measure's text sets some protections. The loan must be fixed-rate, there's no penalty for paying it off early, and lender origination fees are capped. Read the full breakdown of how the loan works →
Who it's for
The name says middle-class, but the income ceiling is high. To qualify under the measure's text, a buyer must:
- Have lived in California for at least one year before applying
- Move in as a primary residence within 60 days of closing
- Have family income of no more than 200 percent of area median income
- Pay at least 3 percent of the price from a source other than a grant or borrowed money
- Be the home's first purchaser
You don't have to be a first-time buyer. SPUR's analysis counts that as a weakness of the measure, since it isn't limited to people who've never owned. Lenders will still need to approve you for the first mortgage. See the full eligibility guide →
Which homes count
This is the biggest limit in the program: it only works on new homes. A "qualified new home" must be newly built, or a nonresidential building converted to housing, and the borrower must be the first purchaser. An existing home on the resale market doesn't count.
The home can be a detached house, townhome, row house, condominium or manufactured home. The price can't exceed 125 percent of the federal conforming loan limit for the county. With FHFA's 2026 limits, that works out to about $1.04 million in most of California and about $1.56 million in the most expensive counties.
What it could cost each month
No one can quote a real payment yet, because CalHFA hasn't set the interest rate or the term. The measure only requires that terms be "practical and favorable" to the applicant while still covering the bonds.
The range matters a lot. CalMatters reports that at a 7 percent example rate, the loan could add about $1,000 a month. The Budget Center warns the rate could end up above a typical first mortgage. The measure's chief backer hopes philanthropic bond buyers could bring it as low as 3 percent. Try the numbers yourself in the monthly cost calculator.
What we don't know yet
Voters set the framework. CalHFA fills in the details, and its rules don't go through the state's normal rulemaking process. Some of the most important questions have no answer today. We'd rather say that than guess.
| Question | Status |
|---|---|
| Can the loan cover up to 17 percent of the price? | Yes, in the measure |
| Is the rate fixed? | Yes, in the measure |
| What's the interest rate? | Not set |
| How long is the loan term? | Not set |
| When can people apply? | Not announced |
| Which lenders will offer it? | Not announced |
| Will investors buy the bonds? | Unknown, flagged by the LAO |
Be careful with anyone offering a Prop 37 loan today. As of November 4, 2026, we found no CalHFA guidance on launch dates, lenders or program rules. If a website or ad quotes you a rate or asks you to apply, ask where that comes from.
How we got here, and what's next
Voters decide
Prop 37 appears on the statewide ballot. Media project passage on election night.
Law takes effect
Initiatives take effect on the fifth day after the Secretary of State files the statement of the vote, under the California Constitution.
CalHFA deadline
The measure requires the program to be implemented no later than one year after the effective date.
Applications open
This depends on CalHFA's rules, bond sales and lender sign-ups.
What you can do now
You can't get this loan today, but a buyer who's ready when it opens will be ahead. Here's useful groundwork:
- Save the 3 percent. The measure says it can't come from a grant or borrowed money. On a $700,000 home, that's $21,000.
- Look up your county's limits in our county table.
- Run the monthly numbers. The down payment gets smaller, but the monthly debt gets bigger. Use the calculator at a few rates.
- Talk to a CalHFA-approved lender about programs open now, and compare the options. Don't wait for Prop 37 if another program fits.
- Get notified. Leave your name and email below, and we'll tell you when applications open.
Prop 37 home loan questions
Did Prop 37 pass?
CBS News projected passage on election night, and early returns showed about 61 percent in favor. Final results come when the Secretary of State certifies the election.
Can I apply for a Prop 37 loan now?
No. CalHFA still has to set rules, sell bonds and sign up lenders. The measure gives it up to one year after the effective date to implement the program.
Is Prop 37 free money?
No. It's a second mortgage that must be repaid. The rate and term haven't been set, but the measure refers to monthly interest payments.
Can I use Prop 37 on an existing home?
No. The home must be newly built, or a converted nonresidential building, and you must be the first purchaser.
Do I have to be a first-time buyer?
The measure's text doesn't require it. You must be a California resident for at least one year, live in the home and meet the income limit.
Is this site run by CalHFA or a lender?
No. This is an independent educational guide. It isn't affiliated with CalHFA or the State of California, it isn't a lender, and nothing here is financial or legal advice.
