Prepayment Penalties And What They Protect

A borrower who repays a loan early is usually charged for the privilege. The charge is not a punishment but compensation for income the lender priced into the original agreement.

Why early repayment costs the lender

A lender writing a fixed-rate loan has committed capital at a rate agreed on a particular day. Its own funding is arranged around that expected stream of payments.

If the borrower repays early, the lender receives capital back at a moment when prevailing rates may be lower, and it can only redeploy at whatever the market now offers.

Prepayment provisions transfer that reinvestment risk back to the borrower. Without them, lenders would price the option into the rate itself, and every borrower would pay for it.

Step-down penalties

The simplest structure charges a percentage of the outstanding balance that declines each year of the loan term, eventually reaching zero for the final period.

Because the charge is known in advance and shrinks predictably, a borrower can calculate exactly what an early exit costs in any given year and plan around it.

This structure is common on smaller commercial loans and on some portfolio lending, and it tends to suit borrowers who expect to refinance or sell within a few years.

Yield maintenance

Yield maintenance calculates what the lender loses by reinvesting at current rates and charges the present value of that shortfall. The cost is therefore driven by where rates sit at payoff.

When prevailing rates are well below the loan rate, the charge can be large. When rates have risen above the loan rate, the charge can shrink toward a minimum floor.

The consequence is that the cost of exiting is unknown until the day it happens, which makes planning harder even though the economics are more precisely fair to both sides.

Defeasance

Defeasance does not repay the loan. The borrower buys a portfolio of securities that produces the same payment stream, and that portfolio is substituted as collateral in place of the property.

This structure appears mainly in loans that have been pooled and sold to investors, where those investors are entitled to the payment schedule they bought and cannot simply be repaid.

It involves specialist advisers, securities purchases and transaction costs beyond the economic charge itself, so the process takes time and is worth starting well before a planned sale.

How this shapes borrowing decisions

Prepayment terms determine how expensive it is to change course, which makes them a question about strategy rather than a detail buried in loan documents.

A long fixed-rate loan with a heavy exit charge suits an owner intending to hold. The same loan on a property intended for sale in three years can consume much of the gain.

Open windows near maturity, partial prepayment allowances and assumption rights all soften the constraint, and they are negotiable terms rather than fixed features of the product.
