Prepayment

Prepayment is the act of paying off all or part of a mortgage loan before its scheduled maturity date. A borrower who makes a lump-sum payment to satisfy the remaining balance, refinances with a new lender, or makes extra principal payments beyond the contractual amount is prepaying the loan. In mortgage note investing, prepayment is generally a positive event — it returns capital to the investor faster than the original amortization schedule anticipated, enabling redeployment into new investments.

Types of Prepayment

Prepayment can take several forms, each with different implications for the note investor:

For note investors holding non-performing loans, the most common prepayment scenarios are discounted payoffs and full payoffs following a loan modification. Both are considered successful resolutions.

Why Note Investors Welcome Prepayment

In traditional mortgage lending, prepayment is viewed as a risk — the lender loses a stream of expected interest income when the borrower pays off early. In mortgage note investing, especially in the non-performing space, the dynamic is reversed:

• Faster capital recovery — the investor bought the note at a discount to UPB. A full payoff at or near face value produces immediate profit and frees capital for the next deal.
• Higher annualized returns — a 100% ROI earned in six months is far more valuable than the same ROI earned over four years. Prepayment compresses the hold period, driving up the internal rate of return (IRR).
• Reduced holding costs — every month a loan sits in the portfolio generates servicing fees, legal costs, and opportunity cost. Prepayment eliminates those ongoing expenses.
• Velocity of money — rapid capital recovery and redeployment is the engine of a note investing business. Prepayment accelerates velocity of money.

This is why experienced note investors structure loan modifications without prepayment penalties. Removing the penalty encourages borrowers to refinance as soon as they qualify, which produces the full payoff the investor wants.

Prepayment Penalties

A prepayment penalty is a clause in the original mortgage that charges the borrower a fee for paying off the loan early. Prepayment penalties were common in subprime lending but are now restricted under federal regulations for most residential mortgages originated after 2014.

For note investors acquiring legacy loans, prepayment penalty clauses may still exist in the original loan documents. The standard best practice is to waive any prepayment penalty when offering a modification:

• Borrowers who complete 6–12 months of payments on a modification are often in a position to refinance with a traditional lender
• Removing the penalty makes that refinance more likely, not less
• A full payoff from a refinance is the investor's best outcome — penalizing it is counterproductive

Prepayment Risk for Performing Note Investors

For investors holding performing loans or re-performing loans purchased at a premium to market value, prepayment does carry downside risk. If an investor pays 80% of UPB for a performing first lien expecting five years of monthly payments, and the borrower refinances after 12 months, the investor may not have recovered enough in interest payments to achieve their target cash-on-cash return.

Modeling Prepayment in Pricing

When pricing a note, sophisticated investors model multiple scenarios that include different prepayment assumptions:

• Base case — borrower pays as scheduled through maturity
• Early payoff — borrower prepays in 12, 24, or 36 months
• Re-default — borrower stops paying and the loan returns to non-performing status

By running these scenarios, the investor determines whether the deal works even under the least favorable prepayment timing. This discipline ensures that the purchase price accounts for prepayment risk rather than being surprised by it.
