Each new year brings many changes, and the mortgage industry is no different. Lending guidelines change frequently, and one of those early-notice changes is the new conforming mortgage loan limits that take effect each year. For 2025, the conforming loan limit for a one-unit, single-family home will be $806,500 in San Bernardino County, up around $40,000 from last year’s limit. This loan limit mirrors most of the country.
However, many more expensive counties in CA like Los Angeles and San Diego have much higher conforming loan limits, in some cases up to $1,209,750. Keep in mind that higher limits will also apply to duplex, triplex and fourplex properties.

What exactly is a conforming loan, and when is it considered a high-cost Jumbo? A conforming loan is one that meets the guidelines issued by Fannie Mae and Freddie Mac. This is important because the more competitive mortgage rates are generally reserved for conforming loans. By far the most popular among residential borrowers, nearly two out of every three mortgage loans made follow these guidelines.
2025 California Conforming Loan Limits:
| Units | Most Counties | High Cost Counties |
| 1 | $806,500 | $1,209,750 |
| 2 | $1,032,650 | $1,548,975 |
| 3 | $1,248,150 | $1,872,225 |
| 4 | $1,551,250 | $2,326,875 |
When Do Buyers Need Jumbo Financing?
Borrowers purchasing more expensive homes in CA will generally take out a jumbo loan. A jumbo loan is one where the loan amount exceeds the conforming loan limits listed above. As stated, a jumbo loan is a loan amount exceeding the prevailing conforming loan limits of $806,500 in most parts of the country. There are also areas where home values and limits are much higher compared to other parts of the country. This means a conforming loan limit can be higher in places such as San Francisco and Los Angeles compared to homes located in Fontana.
Such areas are labeled “high balance” but still fall into the conforming category and are eligible for sale in the secondary markets because they meet guidelines established by either Fannie or Freddie. In these geographic areas, a mortgage will be labeled jumbo if the loan amounts are higher than prevailing conforming limits.
Jumbo loans follow basically the same set of approval guidelines as other mortgage types, but they are slightly more restrictive for approval. Most jumbo loans will require a down payment of at least 10% of the sales price of the home. However, some new options today also permit finance up to 95% for California buyers. Lenders generally provide slightly better terms and flexibility with a 20%+ down payment.
Conforming loans only require a down payment of 3%-5% of the sales price. Of course, when the loan amount is greater than 80% of the value of the home, private mortgage insurance, or PMI, will be required. An additional PMI payment increases the overall monthly mortgage payment for a borrower, but still preserves borrower assets. With a jumbo loan, there is no private mortgage insurance, even for loans exceeding 80% loan to value.
The credit score requirements for jumbo loans can also be higher. Conforming loans only require a minimum credit score as low as 580 whereas a jumbo loan can require a minimum credit score to be 650-680 or even higher.
Note: exact credit scores will depend on down payment and loan amount desired. Please see the complete chart on the Jumbo Purchase page.
Jumbo guidelines set by banks and lenders are typically “verified” which means income, assets, employment and other aspects are verified through third parties. When higher jumbo loan amounts are needed, standard approval guidelines will be followed. This includes debt to income ratio limits, etc.
Jumbo loans can also be refinanced from one loan to a new one. Or, with the new higher loan limits, borrowers with existing jumbo loans may be able to refinance into a conforming loan resulting in a lower loan amount and a slightly better interest rate.
