When you make a full monthly mortgage payment to your loan servicer, it uses part of the payment to reduce the principal balance and some of it to pay interest. If your loan is escrowed for taxes and insurance, part of the payment goes into an escrow account.
If you overpay or underpay, though, those funds will most likely go into a suspense account, which is a catch-all account used to hold funds temporarily. As the name suggests, a "suspense account" is an account that the servicer sets up to keep a borrower's funds in a suspended state until it decides how to allocate them. A suspense account is used primarily when the borrower makes a partial or incomplete payment, or overpays.
The most common use for a suspense account is for partial payments. If you pay only part of what you owe for a particular installment, the suspense account will hold your payment in suspense until a full payment is available.
For example, let's say you split your mortgage payments up and pay two payments per month rather than once a month. The servicer most likely will place the first payment in a suspense account until the second payment is received. Once the suspense account has enough funds to make a full payment, the servicer will remove the funds from suspense and apply them to the account.
Your mortgage lender may also use a suspense account for overpayments. For example, if you always round up when you write out your check to pay the mortgage payment, the servicer might put those funds in a suspense account.
If you dispute any of the amounts that your servicer claims that you owe, don't reduce your payment amount to remove the disputed amount. The servicer might consider your payment a partial payment and place it in suspense until it receives the full payment. Your servicer could then charge you late fees and claim you've defaulted on the mortgage, which can lead to a foreclosure.
The Consumer Financial Protection Bureau (CFPB) issued mortgage servicing rules that went into effect as of January 10, 2014. Among other things, these rules generally require that loan servicers promptly credit a consumer's account on the day a payment is received, subject to a few exceptions.
The rules also state that if a servicer receives a partial payment from the borrower, the payment may be held in a suspense account. When the amount in the suspense account is sufficient to cover a full payment, the servicer must credit the borrower's account.
Sometimes, the servicer makes a mistake and places payments into a suspense account without proper justification.
Example. Say you send in your October payment of $1,100 to your servicer, but the servicer incorrectly records the payment as $100. Because this payment is not a full payment in the eyes of the servicer, it places this amount in a suspense account, and nothing is applied to the loan. The servicer now considers you one month behind in payments. Even if you make November's payment of $1,100 on time and in full, you'll still be considered behind because the servicer will take $1,000 from the November payment, add it to the $100 in suspense and apply that to October's payment. That leaves $100 of the money you sent for November. But because this amount isn't enough to cover the November payment, it will go into suspense, and the cycle will continue.
If you think your loan servicer made a mistake by placing funds into suspense, contact the servicer. If your servicer isn't helpful, consider talking to a lawyer to learn about your legal options.
