Which of the following items are paid in arrears?

The concept of items being paid in arrears refers to obligations that are paid after the service or usage period has occurred. In real estate, interest and property taxes are typically paid in arrears because they are assessed based on past use or ownership.

Interest on a mortgage is calculated based on the outstanding loan balance as of the due date and is paid at the end of the payment period. For example, if your monthly payment is due on the first of the month, you're paying interest for the previous month. Similarly, property taxes are assessed for the prior year of ownership and are generally paid once they become due, directly reflecting the past period when the property was held.

Understanding this timeframe is vital in real estate transactions, particularly during the closing process or when calculating prorations between buying and selling parties. The distinction of other options, while involving payments, does not align with this definition of being regularly paid after service usage. For instance, rents are typically collected in advance, and insurance can be paid in different periods but is often paid upfront or annually rather than in arrears.
