Mortgage Payment Features That Can Hide Future Risk

A low required payment does not always mean a loan balance is shrinking. Some mortgage features postpone principal, allow unpaid interest to build, or leave a large amount due later. Read the repayment structure as carefully as the interest rate. The important question is what your obligation becomes after the first stretch of affordable payments.

The questions below use selected Consumer Financial Protection Bureau guidance, adapted and organized by Fynoptic. Source links and the dates displayed by those sources are provided at the end.

What is negative amortization?

Amortization means paying off a loan with regular payments, so that the amount you owe goes down with each payment. Negative amortization means that even when you pay, the amount you owe will still go up because you are not paying enough to cover the interest.

Your lender may offer you the choice to make a minimum payment that doesn’t cover the interest you owe. The unpaid interest gets added to the amount you borrowed, and the amount you owe increases.

Usually, after a period of time, you will have to start making payments to cover principal and interest. These payments will be higher. A negative amortization loan can be risky because you can end up owing more on your mortgage than your home is worth. That makes it harder to sell your house because the sales price won’t be enough to pay what you owe. This can put you at risk of foreclosure if you run into trouble making your mortgage payments.

Tip

Try to avoid paying interest on interest.

Certain loans have payment options that let you pay only a portion of the amount of interest you owe each month. If you only pay some of the interest, the amount that you do not pay may get added to your principal balance. Then you end up paying not only interest on the money you borrowed, but interest on the interest you are being charged for the money you borrowed. This dramatically increases the amount of debt you have and the cost of the loan. To keep your debt from growing, try to pay down all of the interest and at least some of the principal you owe.

What is an option or payment-option ARM?

An option or payment-option ARM is an adjustable rate mortgage with several possible payment choices.

Some of the payment choices do not cover the full amount needed to pay down the loan. The payment “options” usually include:

  • Paying an amount that covers both your principal and interest. This is the only way you can reduce the amount you owe on your mortgage loan with each payment.
  • Paying an amount that covers only your interest. Interest-only payments do not pay down your principal, or the amount you borrowed.
  • Paying a minimum (or limited) amount that does not even cover the interest. The interest you do not pay will be added to your principal loan balance. This increases the amount of debt you owe.

Tip

If you have an option ARM or a payment-option ARM, always try to pay all of the interest and some of the principal when making your mortgage payment.

Your mortgage payment includes at least two parts – principal and interest. Principal is what you borrowed from the lender. Interest is what the lender charges you for the use of the money you borrowed. Your payment may also include the cost of taxes and insurance if you have an escrow account. If you don’t repay the principal, you are not making any progress in paying back the debt. If you are not paying all the interest, it will get added to what you owe.

If you have a payment-option ARM and you’re regularly skipping your principal or full interest payments to make ends meet, you may be heading for trouble.

What is an "interest-only" loan?

An interest-only mortgage is a loan with scheduled payments that require you to pay only the interest for a specified amount of time.

Tip

Don't assume you’ll be able to sell your home or refinance your loan if your payment increases. The value of your property could decline or your financial condition could change. If you can’t afford the higher payments on today’s income, consider another loan.

The amount that you owe on the loan does not go down with each payment. Once the interest-only period ends, you may have several options:

  • Paying off the loan balance all at once
  • Refinancing the mortgage loan, if refinancing is available
  • Beginning to pay off the balance in monthly payments, which are higher than the interest-only payments

What is a balloon payment? When is one allowed?

A balloon payment on a mortgage is a large, one-time payment at the end of the loan term. If you have a mortgage with a balloon payment, your payments may be lower in the years before the balloon payment is due, but you could owe a big amount at the end of your loan.

Loans with balloon payments generally have shorter terms than traditional mortgages, ranging between 5 and 10 years, compared to 15-30 years. They are designed to have lower monthly payments that do not fully pay off the loan over the term, and then a large last payment, called the balloon. A balloon payment is generally more than two times the loan’s average monthly payment and can often be a significant portion of your entire loan amount. A mortgage with a balloon payment can be risky because you’ll owe a larger payment at the end of the loan.

If you’re considering a balloon loan, you need to think about whether and how you can make the balloon payment when it comes due. If you are unable to make this payment, you could lose your home.

Tip:

Before the end of your loan term when your balloon payment is due, you may be able to refinance your loan to avoid the balloon payment. However, if the value of your property falls, or if your financial condition declines, you might not be able to do so. If you cannot pay the balloon mortgage, even if it’s on the last payment, you could face foreclosure.

Note, balloon payments are not allowed in loans deemed a “Qualified Mortgage”, with some limited exceptions.

What is a demand feature? What does it mean if the demand feature is checked off on my Closing Disclosure?

The Closing Disclosure has a statement that reads "Your loan has a demand feature," which is checked "yes" or "no." A demand feature permits the lender to require early repayment of the loan.

If the demand feature is checked "yes," the lender can require that you immediately pay the entire loan balance (principal and interest) at or after the date set forth in the loan documents. The lender can make this demand on you for any reason or for no reason. Be sure to check your Closing Disclosure and promissory note for any demand features. Think carefully about whether you want to agree to a demand feature, ask for it to be removed, or seek out another mortgage lender. Most mortgage loans do not have a demand feature.

Note: You will not receive a Loan Estimate or Closing Disclosure if you are shopping for:

For these kinds of loans, you should receive Truth-in-Lending disclosures. If you are shopping for a reverse mortgage, you will also receive a Good Faith Estimate (GFE) and a HUD-1 Settlement Statement.

Familiarize yourself with some of the key documents you will be signing so that you know what to look for when you get them.

If you have a problem with your mortgage, you should talk with your lender immediately. You can also submit a complaint to the CFPB online or by calling (855) 411-CFPB (2372).
