Conventional Loan Guide for First-Time Buyers in California

Reviewed by the HomeMath editorial team Updated 2026-08-04

Key takeaways

Conventional loans require as little as 3% down for first-time buyers, though 20% is the threshold to eliminate private mortgage insurance (PMI).
California utilizes escrow companies for closings rather than attorneys, meaning your primary point of contact for the legal transfer of property is your escrow officer.
Lenders typically cap your total debt-to-income (DTI) ratio at 45% to 50%, including your new housing payment and existing debt obligations.
The California Housing Finance Agency (CalHFA) offers down payment assistance programs that can be layered with conventional financing to bridge the affordability gap.

A conventional loan is a mortgage that is not insured or guaranteed by the federal government, unlike FHA or VA loans. Because these loans are held by private lenders and often sold to government-sponsored enterprises like Fannie Mae or Freddie Mac, they follow standardized underwriting guidelines. For first-time buyers in California, these loans offer a path to homeownership that balances competitive interest rates with flexible down payment requirements.

The Down Payment and Private Mortgage Insurance

While many believe a 20% down payment is mandatory, first-time buyers can qualify for conventional loans with as little as 3% down. When you put down less than 20%, the lender views the loan as higher risk and requires Private Mortgage Insurance (PMI). This monthly fee protects the lender if you default on the loan. PMI is not a permanent fixture; once your loan-to-value ratio reaches 80% through principal payments or property appreciation, you can request to have this insurance removed.

Debt-to-Income (DTI) Ratios

Lenders evaluate your ability to repay by calculating your DTI ratio. This is the sum of your monthly debt payments—including student loans, credit cards, and car payments—divided by your gross monthly income. For conventional loans, lenders typically look for a DTI ratio below 45% or 50%. This threshold exists to ensure that your housing costs do not compromise your ability to cover basic living expenses, especially in high-cost California markets.

California-Specific Closing Practices

Unlike many East Coast states that require real estate attorneys to oversee the closing process, California utilizes a neutral third-party escrow company. Your escrow officer acts as the clearinghouse for funds and documents. They collect the buyer’s down payment, the lender’s loan proceeds, and the seller’s deed. They ensure all conditions of the purchase contract are met, record the deed with the county, and distribute funds. Understanding this process is vital because it means your escrow officer, rather than a lawyer, is the primary entity ensuring the legal transfer of title is handled correctly.

Leveraging State Assistance Programs

California is home to some of the most robust down payment assistance programs in the nation, managed primarily by the California Housing Finance Agency (CalHFA). These programs, such as the MyHome Assistance Program, provide deferred-payment junior loans to help with down payments and closing costs. These are often layered on top of a first-lien conventional mortgage. Because these programs have specific eligibility requirements, such as homebuyer education course completion and income limits, you should discuss these options with your loan officer early in the process.

FAQ

How does California being a community property state affect my mortgage application?

In California, assets and debts acquired during a marriage are generally considered community property. Even if only one spouse is on the mortgage loan, the lender may still be required to pull the credit report and consider the debt obligations of the non-borrowing spouse.

Can I use gift funds for my down payment on a conventional loan?

Yes, conventional loans allow for down payment gifts from family members. You must provide a gift letter stating the funds do not need to be repaid, and the lender will require a paper trail showing the transfer of funds from the donor’s account to your account or escrow.

What is the difference between conforming and non-conforming conventional loans?

Conforming loans meet the size and underwriting standards set by Fannie Mae and Freddie Mac. If the loan amount exceeds these limits, it is considered a jumbo loan, which typically requires a larger down payment and stricter credit score requirements.

Do I need to take a homebuyer education course?

If you are a first-time buyer using a low-down-payment conventional loan (such as 3% down), you are generally required to complete an approved homebuyer education course. This course covers the basics of the mortgage process, budgeting, and home maintenance responsibilities.
