Interest-only mortgage: what it means

An interest-only mortgage has scheduled payments that, for a set period, cover only the interest. During that period what you owe does not go down with each payment.

In Spanish it is

Hipoteca de solo intereses

Also written as: interest-only loan · IO loan

The full explanation

According to the CFPB, when the period ends you may pay off the balance all at once, refinance if that is available, or start paying principal with higher monthly payments. The CFPB warns not to assume you will be able to sell or refinance, because the home's value or your finances could change. A Qualified Mortgage (QM) cannot have an interest-only period, and the Loan Estimate labels the feature "Interest Only."

An example

Gerardo is offered low interest-only payments. He asks how much his payment would rise once he starts paying principal, and whether he could afford it on today's income.

You will see it in…

  • The Loan Estimate, page 1, in the product (“Interest Only”)
  • The Loan Estimate, page 2, Adjustable Payment table (“Interest Only Payments?”)
  • Your statement, when the payment rises as the period ends
A man shakes hands with the specialist who helped him with his loan, in the kitchen of his new home.

Still confused by a paper?

A HUD-approved housing counselor can walk you through it. Agencies usually charge little or nothing, many work in Spanish, and they do not sell you anything.
