You are considering a 5 1 ARM What does the 5 represent?

In a 5/1 ARM (Adjustable Rate Mortgage), the "5" represents the initial fixed interest rate period, which lasts for five years. During this time, your interest rate remains constant and is typically lower than a fixed-rate mortgage. After the initial five years, the rate adjusts annually based on a specified index and margin, which can lead to changes in your monthly payments.
