Choosing the right mortgage is about more than just today’s interest rate. One of the most important decisions homebuyers and homeowners face is whether to choose a fixed-rate mortgage or an adjustable-rate mortgage (ARM). Each option has advantages, and the right choice depends on your financial goals, timeline, and risk tolerance.
Understanding how these loan types work can help you make a confident, informed decision.
