When a consumer is preapproved for a line of credit and can use this line freely, making repeat transactions, what is this an example of?

The scenario described is an example of revolving debt. This type of credit allows consumers to borrow from a line of credit up to a certain limit and pay it back over time while having the option to borrow again within the same limit. The key characteristic of revolving debt is that the borrower can make repeat transactions, which is highlighted by the ability to use the line of credit freely and continuously as they pay down the balance.

Revolving credit accounts, such as credit cards or lines of credit, do not have a fixed number of payments. Instead, the borrower can make minimum payments, pay off the balance in full, or draw more funds as they need, making it a flexible financial option. In contrast, the other terms like subordinate lien, reverse mortgage, and mortgage have specific and distinct meanings associated with real estate and structured repayment plans, which do not apply to the ability to freely manage credit through repeat borrowing.
