Final answer:
Most lenders require applicants to disclose at least two years of employment history on a mortgage loan application.
Step-by-step explanation:
On a mortgage loan application, the number of years of employment that are required to be disclosed can vary depending on the lender's requirements and the type of loan being applied for.
However, as a general rule, most lenders require applicants to disclose at least two years of employment history. This helps the lender assess the borrower's stability and ability to make mortgage payments consistently.
