Which of the following is a typical requirement to qualify for a mortgage?

To qualify for a mortgage, a stable employment history is a crucial requirement. Lenders want to see that borrowers have a reliable source of income and a consistent work background, as this demonstrates financial stability and the ability to make regular mortgage payments. A stable employment history indicates that the borrower is likely to continue earning an income that can be used to pay back the loan over time.

In contrast, while a zero debt-to-income ratio might be ideal, it is impractical since most people will have some level of debt. Additionally, home equity is relevant primarily after a mortgage has been obtained, as it measures the value of the homeowner's interest in the property compared to the amount owed on the mortgage. Lastly, payment history with previous landlords could provide insight into a borrower's reliability, but it is not a standard requirement for mortgage qualification like stable employment is. Thus, having a stable job history is a fundamental criterion that lenders assess when determining a borrower's eligibility for a mortgage.
