A mortgage breach letter, also called a demand letter or notice of intent to accelerate, warns that you are in default. It tells you how much to pay and the deadline to fix it, often at least 30 days out. If you do not cure by then, the lender may demand the full balance and start foreclosure.

A letter that talks about "acceleration" and "breach" can feel like the end. It is actually a warning with a deadline, and that deadline is a chance to act.
A breach letter is a formal notice that you have broken, or "breached," a promise in your mortgage, almost always by missing payments. It is usually one of the first legal steps toward foreclosure, and it is required by most standard mortgages before the lender can move ahead.
You may see it called a breach letter, demand letter, notice of default and intent to accelerate, or acceleration warning. The name varies, but the message is the same: pay the past-due amount by a certain date, or the lender may call the whole loan due.
For loans owned by Fannie Mae, servicers generally must send this letter no later than the 75th day of delinquency. So if you have one, you are likely two to three months behind. See how many missed payments before foreclosure.
"Acceleration" means the lender demands the entire loan balance at once, not just the missed payments. It is the step that lets the lender foreclose.
The standard Fannie Mae/Freddie Mac uniform mortgage used for decades spells this out in Section 22, "Acceleration; Remedies." It says the lender must first give you notice that states:
Newer versions of these forms, required for Fannie Mae loans with note dates on or after January 1, 2023, put a similar clause in Section 26. Check your own mortgage or deed of trust for the exact wording and cure period. FHA, VA, and private loans may have different rules.
If you do not cure by the deadline, the lender can accelerate the loan and refer it to foreclosure. That does not happen overnight. Federal rules add a floor: under Regulation X (12 C.F.R. §1024.41(f)), a servicer generally cannot make the first foreclosure notice or filing until you are more than 120 days behind.
| Stage | Typical timing | What you can still do |
|---|---|---|
| Breach letter | Around 60–75 days late | Pay the past-due amount, set up a plan, apply for help |
| Cure deadline passes | Often 30+ days after the letter | Reinstate, apply for loss mitigation, sell |
| First foreclosure filing | Generally after 120 days late | Reinstate, modification, sale, attorney review |
| Sale | Months later, based on state law | Options shrink quickly as the date nears |
What the first filing looks like depends on your state. It may be a notice of default, a notice of sale, or a lawsuit. Our foreclosure timeline covers the full path.
Often, yes. Acceleration does not usually mean you must pay the whole balance to save the home. Many mortgages, including the standard uniform instrument, give you a right to reinstate, meaning you can bring the loan current by paying what is past due plus allowed fees and costs, up to a point before the sale. Some states also set their own reinstatement rules.
You can also ask for loss mitigation, such as a repayment plan, forbearance, or a loan modification. A complete application sent early gives you the most protection under federal rules.
Read the letter slowly and check it. A proper breach letter under a standard mortgage generally includes the default, the amount or action needed to cure, the cure date, and the consequences. Fannie Mae's servicing guide also says the letter must explain the nature of the breach, what is needed to cure it, and the cure date.
Look for mistakes: the wrong amount, a missing cure date, a date shorter than your mortgage requires, or a letter sent to the wrong address. Keep the envelope. In some cases, a defective breach letter can be a defense later in a foreclosure, so show it to a foreclosure attorney if something looks off.

Acceleration is when the lender declares the whole loan balance due right away because of a default. Most mortgages allow it only after a written notice and a cure period. It is the step that opens the door to foreclosure.
Not exactly. A breach letter is a warning that comes before foreclosure starts. It gives you a deadline to cure. A foreclosure notice, like a notice of default, notice of sale, or court summons, comes later if the default is not fixed.
The letter will list a cure date. Under the standard Fannie Mae/Freddie Mac uniform mortgage, it must be at least 30 days from the notice. Federal rules also generally bar a first foreclosure filing until you are more than 120 days behind.
Under the standard uniform mortgage, the notice must state the default, what you must do to cure it, a cure date at least 30 days out, that failing to cure may lead to acceleration and sale, and your right to reinstate and raise defenses. Your own loan documents and state law control the exact rules.
It is risky. Once the cure date passes, the lender can accelerate and add fees, and foreclosure can start after the 120-day mark. Contacting your servicer and a housing counselor right away keeps more options open.
