  • The federal government says that your servicer can't start the foreclosure process until you haven't made a payment in more than 120 days.
  • Before they speed up the process, most lenders will send you a breach letter. This gives you about 30 days to fix the problem.
  • You can avoid acceleration by keeping in touch with your servicer and looking into options like loan modification or refinancing.
  • Even though both an acceleration clause and a due-on-sale clause make your full balance due, they are not the same thing.

What Is an Acceleration Clause?

You know there is a lot of fine print if you've ever looked through a stack of mortgage papers at a closing table. There is an acceleration clause in that stack of papers. Most people don't think about it when they sign, but it can make a big difference later on if your loan goes bad.

Most mortgage contracts have an acceleration clause in them. If you break certain terms of your agreement, the lender has the legal right to demand full repayment of the remaining loan balance, plus any interest that has accrued. The name comes from the idea that the lender will make you pay back the loan faster. The whole amount is due right away, instead of over 15 or 30 years. Most lenders will want the money all at once.
Think about how that looks in real life. Let's say you bought a house for $350,000 and have been paying for it for five years. Your mortgage is still about $310,000. If the lender uses the acceleration clause, you would have to pay the whole $310,000, not just the payments you missed. This isn't just a few thousand dollars. You mean the whole remaining balance of your loan, and you need to pay it all right away.

I have talked to people who bought homes and didn't know this clause was in their paperwork. The Cornell Law Institute says that in Ford Motor Credit Company v. Milhollin, the U.S. Supreme Court said that the Truth in Lending Act does not require lenders to show an acceleration clause on the front of a credit agreement. You might not even notice it in your loan documents. This is why it's important to read your mortgage papers. You don't have to be a lawyer, but you should know the basics of what you're agreeing to. Your lender isn't trying to fool you. It's a normal way for them to protect themselves, and knowing it's there can help you protect yourself too..

What Triggers an Acceleration Clause?

Breaking a key promise you made in your mortgage agreement is one of the main things that can trigger an acceleration clause. The details are different for each loan. You should know about these common triggers.

Missed Mortgage Payments

This is the trigger that gets most people. Your lender can use the acceleration clause if you don't pay your monthly bills on time. Most servicers won't take action after just one missed payment, though. They usually wait until you're three months behind before they send you a formal notice. During that time, the money you owe keeps adding up, so it's best to deal with it as soon as possible.

The Consumer Financial Protection Bureau, a federal agency, says that your servicer can't start the foreclosure process until your mortgage is more than 120 days late. The 120-day window is there so you can look into your options, apply for help with your mortgage, and try to get back on track. If you use that window wisely, it will make a big difference.

Canceled or Lapsed Homeowners Insurance

You must keep homeowners insurance on the property for the whole time you have the loan, as stated in your mortgage agreement. The acceleration clause can kick in if you cancel your policy or let it run out. The reason is simple: the loan is backed by your home, and if something happens to it without insurance, the lender's money is at risk. In real life, a lot of lenders buy a policy for you and add the cost to the amount of money you owe. Force-placed insurance is what that's called, and it's usually more expensive than what you would pay on your own.

Unpaid Property Taxes

Even if things are tough, you still have to pay property taxes. Your local government puts a tax lien on your home if you don't pay them. That lien can be more important than your mortgage, which means that your lender's claim on the property is no longer the most important one. Lenders don't want that, and it could give them a reason to speed up your loan. A lot of mortgage setups have an escrow account that takes care of your property taxes for you. But if your loan doesn't have escrow or if there isn't enough money in it, you have to make sure those taxes get paid. If you miss them, you might get an acceleration letter.

When Are You Looking To Buy A Home

Unauthorized Property Transfer

Selling or transferring your property without your lender's knowledge can trip the acceleration clause. Your lender approved your mortgage based on your credit, income, and financial profile. Handing the property over to someone else without going through the proper channels gives the lender the right to demand the full balance. AmeriSave's loan team walks every borrower through these obligations at closing so there are no surprises down the road.

Bankruptcy Filing

Filing for bankruptcy can also activate an acceleration clause. Bankruptcy affects how creditors collect on debts, and your mortgage lender may see it as a threat to their ability to recover what you owe. Bankruptcy proceedings come with their own set of protections for homeowners, though, so this is an area where you'd want to talk to a qualified attorney.

Acceleration Clause vs. Due-on-Sale Clause

I understand why people get these two mixed up all the time. They both can make your whole mortgage payment due, but they work in different situations. When you sell or give away the property, a due-on-sale clause takes effect. If you sell your home while you still owe money on it, the due-on-sale clause says you have to pay off the rest of the mortgage at closing. People sometimes call this clause a "alienation clause." The Cornell Law Institute says that some due-on-sale clauses only let the lender speed up the process if the sale or transfer would hurt the lender's security interest or if the borrower didn't get the lender's permission first.

An acceleration clause covers breaking the loan terms that have nothing to do with selling. Missed payments, insurance that has run out, and property taxes that haven't been paid are all things that fall under the acceleration clause. What you did that triggers your full balance depends on which clause applies to you.

There are some property transfers that are not subject to these rules. A due-on-sale clause may not apply if your home goes to an heir after you die or if you get a divorce and the ownership changes. There aren't many exceptions to the rule that you can speed up payments if you miss them. Usually, it's clear that the lender can call in the full balance after you've missed a payment.

What Happens After Your Loan Gets Accelerated

Once your lender decides to speed up your loan, things will go through a fairly set process. You can respond quickly if you know what to expect.

The lender usually sends you a breach letter first. This is your official notice that you have broken the terms of your loan. Usually, the breach letter gives you 30 days to fix the problem. If you can fix the default during that time, the lender may lose the right to speed up at all. Don't let this deadline pass. It's one of the most important ones you'll have as a homeowner. The lender sends an acceleration letter when you don't fix the problem in time. This letter tells you how much money you owe in total, including the principal, interest that has built up, and any fees. It also says when the payment is due.

You owe $280,000 on your mortgage and haven't made three payments of $1,800 each. Your lender wants more than just the $5,400 you missed. They want the full $280,000, plus any interest that has accrued and any late fees. That's how the acceleration works. If you can't pay, the next step is usually foreclosure. The rules of the Consumer Financial Protection Bureau say that servicers must look into loss mitigation options for you before going through with a foreclosure sale. Even at this point, you can still find a way out.

How to Avoid Triggering an Acceleration Clause

Keeping your mortgage payments up to date is the best way to avoid having to deal with an acceleration clause. In a perfect world, that would be easy. But things happen in life that cost money. This is what you can do to stay ahead of it. Pay your bills on time. If your budget is tight, see where you can save money before you miss a mortgage payment. You should stop paying your mortgage last, not first. Every payment you miss brings you closer to the trigger that will speed things up.

Ready To Get Approved?

Keep your insurance on your home. Don't let your policy run out, even for a short time. Make sure that the new policy starts before the old one ends when you switch carriers. This way, there will be no gap in coverage. You should also keep up with your property taxes. If your mortgage doesn't have an escrow account for taxes, make a savings plan so you have the money when the tax bills come. Some counties let you pay in installments, which can help you keep track of your money.

Talk to your servicer as soon as you can. If you know you're going to have trouble making a payment, call before you miss one. Most servicers have programs to help you, and they'd rather work with you than start the process of speeding things up. I've helped buyers who were scared to call their servicer. That phone call can open doors they didn't know were there. AmeriSave has tools and resources that can help you keep track of your mortgage and look into your options before small problems become big ones.

What to Do If You Get an Acceleration Letter

Getting an acceleration letter is stressful, no question about it. It doesn't mean you're automatically going to lose your home, though. You have options, and you have time to use them.

Request a Reinstatement

A reinstatement means you pay all the past-due amounts, plus any fees and costs, to bring your loan current. Once you do that, the acceleration goes away and your regular payment schedule picks back up. Some lenders will even set up a repayment plan to spread those catch-up payments over several months instead of requiring all the money at once in one big lump sum.

Look Into Refinancing

When your monthly payment is the root problem, refinancing can help. A new loan with a longer term or a lower interest rate might bring your payment down to something manageable. AmeriSave's team can walk borrowers through refinancing options and show what a new payment could look like. This is one of those situations where running the numbers early saves you a lot of headaches later.

Consider a Loan Modification

A loan modification changes the terms of your existing mortgage without requiring you to refinance into a new one. Your lender might agree to lower your interest rate, extend your loan term, or even reduce the principal balance in some cases. Not every borrower qualifies, but it's worth asking about, especially if you can demonstrate that your financial hardship is temporary.

Work With a HUD-Approved Housing Counselor

The U.S. Department of Housing and Urban Development pays for free housing counseling services all over the country. A HUD-approved counselor can help you understand your choices, look over your finances, and even talk to your servicer for you. You can get in touch with a counselor by calling the HOPE Hotline or going to the CFPB's website. You don't have to pay for this service, and it can really help you figure out what to do next. Fannie Mae and Freddie Mac also have tools that can help you find out who owns your loan. This is important when you're looking for help programs that might work for you.

Be careful of foreclosure rescue scams, though. If someone calls you and says they can stop your foreclosure for a fee, it's a red flag. You can get real help for free from HUD-approved organizations. Don't pay someone for something you can get for free.

The Bottom Line

Almost every mortgage has an acceleration clause. You didn't think much about it when you signed it, and you can't change it. You now know what it is and what makes it happen. Read the papers for your loan. Keep up with your property taxes, insurance, and payments. Before you fall behind, talk to your servicer if things get tight. The people at AmeriSave can help you figure out what to do next. Not doing anything is the worst thing you can do.

Frequently Asked Questions

Most mortgage contracts let the lender speed up the process after any default, even if it's just one missed payment. But in real life, lenders almost never do this after just one month. They usually send a breach letter after you've been late for about 90 days. The Consumer Financial Protection Bureau (CFPB) also says that your servicer can't start foreclosure until you're more than 120 days behind on your payments. If you miss a payment, get in touch with your servicer right away. AmeriSave's prequalification tool can also help you see if refinancing into a more affordable payment makes sense.

No. If you break the terms of your loan, such as by missing payments or letting your insurance lapse, an acceleration clause lets the lender demand full repayment right away. A due-on-sale clause, also known as an alienation clause, says that the full balance is due when you sell or give away the property. Both can make you owe the whole remaining balance at once, but they apply to different situations. Your mortgage probably has both. You can find educational guides on mortgage terms in AmeriSave's Resource Center.

Not always. The Truth in Lending Act doesn't require lenders to put an acceleration clause on the front of a credit agreement, according to the U.S. Supreme Court. You can still find the clause in your loan documents if you read through the mortgage or deed of trust carefully. When you buy a house, ask your real estate lawyer to go over the most important parts with you. AmeriSave's Resource Center also has helpful breakdowns.

Don't ignore it. Read the letter carefully and pay attention to the date it gives you. Then get in touch with your servicer right away to talk about your choices. You might be able to get a reinstatement, a loan modification, or a repayment plan. You can also get free help from a HUD-approved housing counselor. The CFPB's counselor finder is a good place to start. You can see if refinancing could lower your payment on AmeriSave's current rates page.

Yes, in many cases. If you cure the default before the lender starts the foreclosure process, it can often stop the acceleration. This usually means paying off all of your debts, including back payments, late fees, and any legal fees. Some states also give borrowers a legal right to reinstatement, which means that the law gives them a set amount of time to fix the problem. You need to act quickly because time is important. Check out AmeriSave's prequalification page to see if refinancing will help you get back on track.

The Consumer Financial Protection Bureau (CFPB) says that your servicer can't file the first notice or document to start a foreclosure until your loan is more than 120 days late. After that, the time frame depends on the laws in your state about foreclosures. Some states require a court process that can take months or even years. Some states let people foreclose without going to court, which usually happens faster. The Resource Center at AmeriSave has guides that explain what to expect.

Across the country, mortgage contracts often have acceleration clauses that are legal. However, local laws can change how and when a lender enforces one. Some states offer borrowers extra protections, such as required mediation programs or longer cure periods. If you're not sure what the laws are in your state, talk to the real estate lawyer who helped you close. If you need a payment that is easier to handle, AmeriSave can help you look into refinancing options.

The acceleration clause is a standard part of most home loans that can't be changed. Lenders include it to protect their money, and they don't often take it away. Sometimes you can negotiate how your lender will act when something that could trigger a problem happens. For instance, some servicers will agree to a forbearance plan instead of speeding up the process, especially if you call them before you miss a payment. When you work with a knowledgeable loan team, like the one at AmeriSave, you'll know what your options are from the start.

When you file for bankruptcy, an automatic stay goes into effect. This stops most collection actions, including foreclosure, for a short time. But this doesn't get rid of the acceleration. After the bankruptcy case is over, the lender can usually pick up where they left off. If you file for Chapter 13 bankruptcy, you can make a repayment plan that lets you catch up on missed mortgage payments over time while still keeping your home. If you need help with your bankruptcy case, talk to a lawyer. For more information, go to the HUD foreclosure prevention page. For mortgage education guides, go to AmeriSave's Resource Center.

The U.S. Department of Housing and Urban Development pays for housing counseling agencies that are free or low-cost all over the country.
