When sponsors compare long-term commercial real estate loans, the conversation usually starts with rate, proceeds, amortization and term.

But one of the most important economic provisions may not matter until years later: how the loan can be prepaid.

Defeasance and yield maintenance are both designed to protect the lender's expected return if a borrower exits early. For sponsors, however, they create different risks around sale timing, refinancing, transaction costs and execution.

The better question is not simply which one is cheaper. It is which structure creates more risk for the sponsor's expected exit.

How Yield Maintenance Affects the Exit

Yield maintenance generally requires the borrower to compensate the lender for the economic loss created by early repayment.

The exact calculation depends on the loan documents, but it typically considers factors such as the remaining loan balance, contractual interest rate, remaining term and an applicable Treasury or other benchmark rate.

This makes yield maintenance highly sensitive to the rate environment.

If market rates decline materially below the existing loan coupon, the penalty can become expensive because the lender is giving up an above-market stream of interest payments.

If market rates increase, the economic penalty may decline.

For sponsors, this can create an unusual situation: a refinance may look attractive because new debt is cheaper, but the cost of exiting the existing loan can eliminate much of the expected savings.

That is why refinancing decisions should be based on total economics rather than the new coupon alone.

Considering a refinance? Before approaching the market, Lever can help determine whether the interest savings actually outweigh your existing loan's exit costs.

Defeasance Creates a Different Type of Risk

Defeasance does not typically operate as a simple prepayment penalty.

Instead, qualifying securities are purchased and pledged to generate the cash flows required to satisfy the remaining scheduled debt payments. Once the process is completed, the real estate collateral can generally be released.

The economic cost still depends heavily on interest rates and the remaining loan term, but defeasance also introduces execution complexity.

A transaction may involve:

That additional coordination can matter when a property is under contract and the buyer expects a specific closing date.

A sponsor that discovers the defeasance requirement late in the sale process may face more than an unexpected cost. It may also face timing risk.

Which One Costs More?

There is no universal answer.

The cost of either structure depends on:

Yield maintenance may sometimes be easier to estimate and execute, while defeasance may involve more third-party expenses.

But comparing only the headline penalty misses the larger issue.

The real comparison should include:

For a sponsor expecting to sell in three years, these terms may be far more important than they are for an investor intending to hold through maturity.

Sale Timing Can Change the Analysis

Prepayment structure becomes particularly important when the property's business plan depends on a defined exit window.

Suppose a sponsor intends to stabilize an asset and sell once NOI reaches a target level. If that occurs several years before loan maturity, a large prepayment obligation could materially reduce the expected equity return.

Defeasance may create additional coordination around the sale closing.

Yield maintenance may create a significant cash charge.

Either structure can affect whether selling at that moment still makes economic sense.

Sponsors should therefore model multiple exit dates when evaluating permanent debt, not simply assume the property will be held for the full loan term.

If a sale or recapitalization is already on the horizon, waiting until the asset is under contract to evaluate the debt can limit your options. Lever can review the existing structure before the exit timeline becomes fixed.

Assumption Can Provide Another Option

Prepayment is not always the only path.

If the loan is assumable, a buyer may be able to take over the existing financing rather than requiring the seller to defease or pay yield maintenance.

That can be especially valuable when the existing debt carries a below-market rate.

An attractive assumable loan may:

However, assumption usually requires lender approval, buyer qualification and additional fees. The existing loan amount may also be too small relative to the buyer's desired leverage.

Sponsors should understand the assumption provisions at origination rather than discovering them during a sale.

Open Periods Matter More Than They Appear

Many loans provide a period near maturity when repayment can occur with reduced or no prepayment penalty.

The exact timing matters.

A sponsor facing a costly exit six months before the open period may decide to delay a sale or refinance. That decision can affect pricing, investor distributions and exposure to changing market conditions.

Sponsors should know precisely when the open period starts and what restrictions still apply.

Underwrite the Exit Before Closing the Loan

Before accepting defeasance or yield maintenance, sponsors should evaluate:

A loan with slightly better pricing today may ultimately be more expensive if its prepayment structure prevents the sponsor from executing the business plan efficiently.

Comparing permanent loan options now? The lowest coupon is not always the lowest-cost capital. Lever can compare lender proposals based on both today's economics and the flexibility they leave at exit.

How Lever Capital Partners Can Help

Lever Capital Partners helps sponsors compare financing based on the full economics of the loan, not just the initial interest rate.

That includes evaluating prepayment provisions, assumption rights, open periods and expected hold periods across competing lenders.

Lever can also help sponsors assess whether a proposed refinance or sale remains economically attractive after defeasance, yield maintenance and transaction costs are considered.

The objective is to align the debt structure with the investment strategy.

Defeasance and yield maintenance can both create meaningful exit costs. The better structure depends on when the sponsor expects to sell, refinance and return capital.

For experienced sponsors, exit flexibility should be underwritten at the same time as the loan itself.
