Zero Interest Down Payment Assistance Programs are an important part of CalHFA Loan Programs, designed to help first-time and low- to moderate-income homebuyers reduce the upfront cost of purchasing a home. These programs offer down payment and, in some cases, closing cost assistance with no monthly interest charges, helping keep mortgage payments affordable. Typically structured as deferred or low-balance junior loans and paired with eligible CalHFA first mortgage options, zero interest assistance programs make homeownership more attainable by easing cash requirements at closing while supporting long-term financial stability.
For many aspiring homeowners in California, the largest hurdle to purchasing a home is not the monthly mortgage payment, but the upfront liquidity required to close the deal. While saving for a down payment is a known challenge, many first-time buyers are blindsided by ‘closing costs’—the fees for title, escrow, taxes, and insurance—which can add thousands of dollars to the transaction.
To address this, the California Housing Finance Agency (CalHFA) offers the Zero Interest Program, commonly known as ZIP. This program is a specialized subordinate loan designed to cover closing costs, thereby reducing the amount of cash a borrower needs to bring to the closing table.
This report details the workings of the ZIP loan from a borrower’s perspective, explaining how it functions, which loans it pairs with, and the strict rules regarding repayment and refinancing.
The Zero Interest Program (ZIP) is a deferred-payment junior loan. It is important to clarify a common misconception: while ZIP is often categorized broadly under “down payment assistance,” it is strictly limited to covering closing costs and prepaid items. It cannot be used to fund the down payment itself or to pay off borrower debt.
The “Zero Interest” Feature
As the name implies, the defining feature of this loan is its interest rate. The ZIP loan carries a 0.00% interest rate. This means that if you borrow $10,000 to pay your closing costs, the balance will remain $10,000 for the life of the loan. It does not accrue interest over time, unlike the MyHome Assistance Program or MyAccess Program., which typically charge 1.00% simple interest.
Deferred Payments
From a cash-flow perspective, the ZIP loan is designed to be invisible to your monthly budget. Payments on the ZIP loan are deferred for the life of the first mortgage. You do not make monthly installments on this debt. Instead, the loan sits silently in a subordinate lien position until a specific event triggers the need for repayment.
The amount of assistance you can receive through ZIP is determined by the size of your first mortgage.
Borrowing Options
Borrowers can generally choose between two options based on their needs and the daily rate sheet pricing:
Strict Usage Rules
Because ZIP is funded differently than other assistance programs, its usage is strictly regulated.
You cannot add a ZIP loan to just any mortgage. The Zero Interest Program is exclusively available when paired with specific “CalPLUS” first mortgage products. It cannot be used with standard CalHFA loans or the Dream For All program.
To utilize ZIP, you must select one of the following first mortgages:
A. CalPLUS Conventional
This package combines a Fannie Mae HFA Preferred first mortgage with the ZIP loan.
• Structure: The CalPLUS Conventional first mortgage features a fixed interest rate. Because it includes the ZIP assistance, the interest rate on the first mortgage is typically slightly higher than the standard “CalHFA Conventional” loan to offset the cost of the 0% assistance.
B. CalPLUS FHA
This package combines an FHA-insured first mortgage with the ZIP loan.
• Structure: Similar to the conventional version, this allows FHA borrowers to access 0% funds for closing costs.
“Stacking” with MyHome
A major advantage of the CalPLUS/ZIP structure is the ability to “stack” assistance. Since ZIP covers closing costs but not the down payment, borrowers often combine it with the MyHome Assistance Program to cover the down payment.
In a stacked scenario, your financing would look like this:
1. 1st Lien: CalPLUS Conventional or FHA First Mortgage.
2. 2nd Lien: MyHome Assistance (covering the down payment).
3. 3rd Lien: ZIP Assistance (covering closing costs).
This layering strategy allows a borrower to enter a home with virtually zero funds from their own pocket, covering both the required down payment (via MyHome) and the closing fees (via ZIP).
A common question among homebuyers is whether this assistance is a grant that disappears over time. The answer is no.
The Zero Interest Program is not forgivable. It is a debt that you are legally obligated to repay. While the 0% interest rate makes it very affordable, the principal balance remains a lien against your home until it is paid in full.
Since payments are deferred, you generally will not pay back the ZIP loan until you exit the home or the mortgage. Repayment of the principal balance is due in full upon the earliest of the following “Trigger Events”:
1. Transfer of Title: If you sell the home or transfer ownership to someone else.
2. Refinance of the First Loan: If you decide to refinance your CalPLUS first mortgage to get a lower interest rate or different term.
3. Payoff of the First Loan: If you pay off your 30-year mortgage in full (e.g., reaching the end of the 30-year term).
4. Default: If you fail to make payments on your first mortgage and a Notice of Default is formally filed and recorded.
Because the interest rate is 0%, the amount you owe at the end is exactly the same as the amount you borrowed at the beginning. If you borrowed $8,000 for closing costs, you will owe CalHFA $8,000 when you sell the house, regardless of whether that sale happens in 5 years or 25 years.
One of the most critical restrictions of the ZIP loan involves subordination. Subordination is the process of asking a second or third mortgage holder to stay in the back seat while a new first mortgage takes the driver’s seat during a refinance. Check current CalHFA Income Limits before proceeding to ensure eligibility limits match your area.
Can ZIP be subordinated? Generally, No.
While the ZIP loan has no interest, it does come with a small administrative cost.
To qualify for a ZIP loan, you must be a first-time homebuyer for the CalPLUS first mortgage program it is attached to.
The Zero Interest Program (ZIP) is a powerful tool for buyers who have the income to support a mortgage but lack the liquidity to pay for closing costs. By providing 2% to 3% of the loan amount at 0% interest with deferred payments, it removes a significant barrier to entry.
However, borrowers must recognize that ZIP is a repayable loan, not a gift. It is strictly for closing costs (not down payments), and it creates a financial obligation that must be satisfied if you choose to refinance or sell your home in the future. The inability to subordinate the loan means borrowers should view the CalPLUS/ZIP package as a commitment that may require significant equity growth before a refinance is viable.
Both ZIP and Dream For All loans become due upon the occurrence of a “trigger event.” The most common triggers are:
1. Selling the property.
2. Transferring the title to someone else.
3. Refinancing the first mortgage (with the one-time exception for Dream For All).
4. Paying off the first mortgage in full (e.g., after 30 years).
5. Formal filing of a Notice of Default (foreclosure initiation). Because payments are deferred for the entire loan term, borrowers must plan for this eventual balloon payment when they decide to sell or alter their financing.
No, you cannot “stack” the Dream For All Shared Appreciation Loan with the Zero Interest Program (ZIP) or the MyHome Assistance Program. You must choose one path: either the high-equity Dream For All loan (up to 20% assistance) OR the CalPLUS path which combines MyHome (down payment) and ZIP (closing costs). However, Dream For All can be layered with other non-CalHFA subordinate loans, such as community grants or city-specific assistance, provided those loans meet Fannie Mae Community Second guidelines.
For the Zero Interest Program (ZIP), refinancing your first mortgage generally triggers an immediate repayment requirement. CalHFA typically does not subordinate ZIP loans to a new first mortgage, meaning you must pay off the ZIP balance in full when you refinance. However, for the Dream For All program, CalHFA allows a one-time limited cash-out refinance of the first mortgage without requiring immediate repayment of the shared appreciation loan, provided you meet specific resubordination guidelines at the time of the transaction.
Although the Dream For All loan has a 0% interest rate, you compensate the program by sharing your home’s equity. If your income is within standard limits, you generally repay the principal plus 20% of the home’s appreciation upon sale. If you are a lower-income borrower (≤80% AMI), the share is reduced to 15% of the appreciation. This “shared appreciation” model replaces traditional interest. The total amount you repay (principal + appreciation) is capped at 2.5 times the original loan amount to protect you in rapidly rising markets.
No, neither the Zero Interest Program (ZIP) nor the Dream For All Shared Appreciation Loan are forgivable grants. They are deferred-payment loans that result in a lien being recorded against your property. You are legally obligated to repay the funds. For ZIP, you repay the original principal amount. For Dream For All, you repay the principal plus the program’s share of the appreciation. The only exception in CalHFA’s portfolio is the ADU Grant Program, which is a true grant for Accessory Dwelling Units and does not require repayment.
The loan amount for ZIP is calculated as a percentage of your first mortgage amount, not the sales price. Borrowers can typically choose between a ZIP loan of 2.00% or 3.00% of the first mortgage balance. For example, on a $400,000 mortgage, a 3% ZIP loan would provide $12,000 in assistance for closing costs. Because the interest rate on the CalPLUS first mortgage may vary based on the ZIP amount chosen (2% vs 3%), borrowers should review pricing options with their lender to decide which level of assistance is most beneficial.
Not necessarily. To qualify for ZIP, you must be a First-Time Homebuyer and meet CalHFA’s income limits for your county. Additionally, ZIP is not a standalone product; it must be paired exclusively with a CalPLUS first mortgage (CalPLUS Conventional or CalPLUS FHA). This means if you choose a standard “CalHFA Conventional” or “CalHFA FHA” loan, you are not eligible for ZIP. You must specifically select the CalPLUS loan product, which may have a slightly higher interest rate on the first mortgage to offset the benefit of the zero-interest assistance.
The Dream For All Shared Appreciation Loan is a distinct zero-interest program aimed at first-generation homebuyers. It provides a loan for up to 20% of the home’s value (capped at $150,000) for down payment and closing costs. While the interest rate is listed as 0.00%, the cost of borrowing is determined by the home’s growth in value. Instead of paying interest, you repay the original principal plus a share of the home’s appreciation (equity growth) when you eventually sell, transfer, or refinance the property.
No, ZIP funds are strictly limited to closing costs and prepaid items. You generally cannot use ZIP proceeds to satisfy the minimum down payment requirement for your loan. If you need assistance with the down payment, you must combine ZIP with another program, such as the MyHome Assistance Program. MyHome can be used for the down payment, while ZIP covers the closing costs, allowing for a “stacked” assistance structure where MyHome is in the second lien position and ZIP is in the third lien position.
The Zero Interest Program (ZIP) is a subordinate loan designed to help homebuyers cover closing costs and prepaid items (like taxes and insurance). As the name implies, it carries a 0.00% interest rate for the life of the loan. It is a deferred-payment loan, meaning you do not make monthly payments on it. The principal balance remains constant because no interest accrues. You are only required to repay the exact amount you borrowed when a specific “trigger event” occurs, such as selling the home, refinancing, or paying off your first mortgage.
