Frequently Asked Questions

What is an ARM loan?

An Adjustable-Rate Mortgage (ARM) has an interest rate that changes periodically based on market conditions. Most ARMs have a fixed rate for an initial period (e.g., 5, 7, or 10 years), then adjust annually.

When does an ARM make sense?

ARMs work well if you plan to sell or refinance before the rate adjusts, want lower initial payments, or expect your income to increase significantly.

How much can my ARM rate increase?

ARMs have rate caps that limit how much the rate can increase per adjustment period and over the life of the loan. Common caps are 2/2/5 (2% per adjustment, 5% lifetime).

Is a fixed-rate mortgage safer?

Fixed-rate mortgages provide payment stability and protection against rising rates, making them safer for long-term homeownership.
