Which loan feature distinguishes a jumbo loan from a conforming loan?

A jumbo loan is specifically characterized by its lending limit, which is the key feature that differentiates it from a conforming loan. Conforming loans must adhere to the standards set by government-sponsored entities, primarily concerning the maximum allowable loan amount, which varies by county and is subject to annual adjustments. In contrast, jumbo loans exceed these limits, making them non-conforming.

The relevance of the lending limit is paramount because it directly impacts eligibility for various secondary market programs, government guarantees, and therefore, the terms and conditions available to borrowers. Since jumbo loans are seen as carrying higher risk for lenders due to the larger amounts and absence of government backing, they often come with stricter underwriting requirements and potentially higher interest rates, but it is the surpassing of the conforming limit that is the defining feature of a jumbo loan.
