Fullerton Conforming Loan Limit 2026
Fullerton features upscale residential neighborhoods such as Sunny Hills and Amerige Heights, along with top-rated school districts. Because of this, the Federal Housing Finance Agency (FHFA) designates the area as a High-Cost Area.
As a result, the 2026 conforming loan limits for Fullerton (Orange County) are significantly higher than those in standard-priced regions.
If your loan amount is within the limit, you may qualify for a Conforming Loan, which typically offers lower interest rates and more flexible underwriting standards.
If your loan amount exceeds the limit, it will be classified as a Jumbo Loan, requiring higher credit scores and stronger asset documentation.
