How can I tell whether I have a fixed-rate or adjustable-rate mortgage?

Short answer

You can ask your servicer, check the Closing Disclosure or Truth-in-Lending disclosure you received, or read the promissory note. If you applied after October 3, 2015, the rate type is at the top of page 1 of the Closing Disclosure. An adjustable-rate note often says the interest rate will change.

Full explanation

The CFPB lists several ways to tell whether the rate is fixed or adjustable.

Call the servicer, the company you pay each month. The phone number may be on the monthly statement or payment coupons.

Check the disclosures from when you got the loan. If you applied after October 3, 2015, look at the Closing Disclosure; the interest-rate type is at the top of page 1. If you applied before that date, or if you have a reverse mortgage, a HELOC, a manufactured-housing loan not secured by real estate, or a loan through certain homebuyer-assistance programs, look at the Truth-in-Lending disclosure for variable-rate language.

You can also read the promissory note signed at closing. An note may be titled as an adjustable-rate note and may say the interest rate will change under a numbered section. Use more than one of these checks if the paperwork is incomplete.
