Terminology Guide for Borrowers
Not sure what these terms mean? Here’s a mini glossary of loan limit terminology:
Conforming: A California “conforming” home loan is one that falls within the maximum size limits used by Fannie Mae and Freddie Mac. These caps are established by the Federal Housing Finance Agency (FHFA). In short, if a California home loan falls within these conforming limits, it can be sold to Freddie and Fannie via the secondary mortgage market. Anything larger is considered a jumbo loan and cannot be sold into the secondary market. These limits vary by county, as shown in the table above.
Conventional: The term “conventional” is used to describe mortgage products that are not insured by the government. This distinguishes them from FHA and VA loans, which are insured or guaranteed by the federal government. California conventional home loans are originated (and sometimes insured) within the private sector, with no government backing.
Loan limit: This is the maximum borrowing amount within a certain mortgage loan category. For instance, the maximum amount for a conforming single-family home loan in San Diego County is $649,750. There are caps for other products as well, including FHA and VA mortgage programs. They also vary by county and are based on median home prices.
Rising Prices Bring Higher Limits in 2018
At the end of 2017, federal housing officials increased the conforming loan limits for California, in response to rising home prices across the state (and elsewhere in the U.S.).
In a November 28 press release, the Federal Housing Finance Agency stated:
“The Federal Housing Finance Agency (FHFA) today announced the maximum conforming loan limits for mortgages to be acquired by Fannie Mae and Freddie Mac in 2018. In most of the U.S., the 2018 maximum conforming loan limit for one-unit properties will be $453,100, an increase from $424,100 in 2017 … The new ceiling loan limit for one-unit properties in most high-cost areas will be $679,650.”
