Variable Rate Mortgage

What Is a Variable Rate Mortgage?

A variable rate mortgage is a loan with an interest rate that may change periodically based on a benchmark index.

It is commonly structured as:

Index + Margin = Interest Rate

These loans are also known as adjustable-rate mortgages (ARMs).

Why It Matters in a Mortgage

Variable rates may:

  • Offer lower initial payments
  • Increase payment uncertainty
  • Shift based on market conditions

Interest rate changes are influenced by financial benchmarks shaped by institutions like the Federal Reserve.
