Acceleration clause
An acceleration clause lets a lender declare the entire outstanding balance immediately due when the borrower defaults.
It is a short provision with enormous consequences, and it explains the single most confusing thing about mortgage default: why missing four payments produces a demand for two hundred thousand dollars.
Without it#
A lender could pursue only what was actually missed. Four payments, plus fees.
Foreclosure would be a remedy for the arrears, and the property would secure a claim of a few thousand dollars.
With it#
The whole loan becomes due at once. The foreclosure is for the entire debt, and the amount claimed in the notice of foreclosure sale is the full balance rather than the arrears.
That is what makes a payoff figure so far removed from what the borrower fell behind by.
How it usually operates#
The loan documents set the conditions, and the ordinary sequence is:
Default occurs. The servicer sends a breach letter identifying the default and giving an opportunity to cure by a stated date. If the default is not cured, the lender accelerates and refers the matter to foreclosure counsel.
The breach letter is therefore the last easy exit, and it arrives with a deadline on it.
Reinstatement undoes it#
The counterweight, and the reason acceleration is less final than it sounds.
Minn. Stat. 580.30 permits reinstatement at any time before the sheriff's sale, in both foreclosure by advertisement and foreclosure by action. Paying the amount actually due plus permitted costs restores the loan to its original schedule.
So acceleration makes the whole balance due, and reinstatement re-decelerates it. The right survives right up to the sale, and the statute caps the attorney's fee component so the figure cannot inflate without limit.
Two numbers, two questions#
This is the practical takeaway.
The payoff answers "what does it cost to end this loan" — the accelerated balance plus interest and costs.
The reinstatement figure answers "what does it cost to get current" — the arrears plus permitted costs.
A borrower who asks the first question hears an impossible number and frequently stops trying. The second question is the one that determines whether the house can be kept, and it has to be asked specifically.
After the sale#
Acceleration and reinstatement both become irrelevant.
Once the sheriff's sale has happened, the number is the redemption amount — the sale price plus interest and advances — and neither the arrears nor the loan balance is the relevant figure any longer.
