Balloon Payment in Commercial Mortgages

A balloon payment is the principal balance still owed on the maturity date of a commercial mortgage. It arises when the amortization schedule runs longer than the loan term, or when some or all of the term is interest only. The borrower retires that balance from a refinancing, a sale or cash on hand, so the loan depends on two things: the income the property earns today and whether a new lender will finance it on the maturity date.

Why a 30-year schedule on a 10-year loan leaves a balance

Two clocks run on every commercial mortgage. The term sets the date the whole debt falls due. The amortization schedule sets how each level payment splits between interest and principal.

A standard conduit structure pairs a fixed rate, a 10-year term and a 30-year amortization schedule. Payments are sized as if the loan would run 30 years, then the note ends after 10. Early payments are mostly interest, so the balance falls slowly, and what remains at the end of year 10 is the balloon.

Interest-only periods push the balloon higher. Scheduled principal is zero during those months, and a loan that is interest only for the full term reaches maturity owing the original amount. A partial interest-only loan starts amortizing later and lands between the two extremes.

Terms vary. Commercial loans run from five years, or even less, up to 20 years, so one amortization schedule can produce very different maturity balances depending on how many payments the term allows.

“The mortgages are typically 10-year, fixed-rate loans with a 30-year amortization schedule and a large balloon payment at maturity, although these mortgages may also have shorter maturities or may be partially or fully interest-only.”

Balloon exposure by capital source

Banks and life insurers are two of the primary capital sources behind outstanding commercial mortgages outside multifamily, and CMBS is another. Their loans do not repay the same way.

Commercial mortgages that a lender holds directly tend to amortize, while CMBS mortgages typically carry balloon payments. The same pattern shows up in life insurer portfolios, where the securitized mortgages also have higher average loan-to-value ratios at origination than the directly held ones. A higher ratio means less equity under the loan on day one.

A commercial mortgage can also be adjustable rate and may require no principal until maturity, which a conventional homeowner loan does not. A borrower comparing quotes from different lender types is comparing repayment obligations as well as rates.

Reading the balloon as a share of the original loan

Commercial loans rarely repay in full during the term, so borrowers often owe a balloon equal to 80 to 90 percent of the original balance.

That range is a share of original principal and says nothing about current property value or income.

The share for a given note depends on the rate, the amortization period and the number of payments made. A longer schedule, a higher rate or an interest-only stretch each raises the share, because less principal is retired before the date arrives.

Because most loans arrive at maturity with most of the principal outstanding, the refinancing market is built around them.

What happens when a takeout loan is not available

The balloon is a contractual amount, and nothing in the note obliges another lender to take it out.

When a borrower has business problems or refinancing alternatives are limited, payments can be delayed or the loan can default. For a loan held in a securitization, that can delay cash flow to bondholders or cause losses.

The balance is known on the first day of the loan. Whether the property can support a new loan of that size is answered only near maturity.

Worked example: a hypothetical $10 million loan with an $8.4 million balloon

This illustration uses round hypothetical numbers. A $10,000,000 loan has a 10-year term and a 30-year amortization schedule. After ten years of payments the illustrative balance is $8,400,000.

Step 1, the balloon share. $8,400,000 divided by $10,000,000 is 84 percent of the original balance. Amortization retired $1,600,000 of principal, which is $10,000,000 minus $8,400,000.

Step 2, sizing the takeout. A hypothetical lender sizes the new loan at a 10 percent debt yield, meaning net operating income divided by loan amount. Closing costs are 1 percent of the new loan. Both cases use the same $8,400,000 payoff.

Base case: net operating income at maturity is $900,000. The new loan is $900,000 divided by 0.10, or $9,000,000. Costs are $9,000,000 multiplied by 0.01, or $90,000, leaving $8,910,000 net. Net proceeds minus the $8,400,000 payoff leaves a $510,000 surplus.

Stressed case: net operating income at maturity is $800,000. The new loan is $800,000 divided by 0.10, or $8,000,000. Costs are $80,000, leaving $7,920,000 net. The $8,400,000 payoff minus $7,920,000 leaves a $480,000 shortfall that equity or other capital must cover.

Income fell by $100,000 between the cases. At a 10 percent debt yield the new loan fell by $1,000,000, and costs fell by only $10,000, so net proceeds fell by $990,000. That is the same $990,000 as the swing from a $510,000 surplus to a $480,000 shortfall.

The balance owed never changed. The sizing test applied to income did.

Balloon analysis mistakes that distort the maturity picture

Treating the original loan amount as the balloon overstates the payoff on an amortizing loan. In the example, $10,000,000 would be the payoff only if the loan were interest only for the full term. The true payoff is $8,400,000.

Applying the 80 to 90 percent range to every loan misreads a statistic. It describes commercial borrowers broadly, and a specific note produces its own percentage from its rate, amortization period and interest-only months.

Confusing the amortization period with the term makes a loan look 30 years long. The note still matures at year 10, and the schedule only determines how much is left on that date.

Comparing gross refinancing proceeds with the payoff skips closing costs. In the base case the new loan is $9,000,000, but only $8,910,000 reaches the payoff.

Reading today’s debt yield as the maturity test overlooks that the new lender sizes on income at maturity. The same payoff produced a surplus at $900,000 of income and a shortfall at $800,000.

Checklist questions for a balloon maturity review

What is the contractual maturity date? Principal becomes due on that day whatever the amortization schedule says.

What amortization period sets scheduled principal? A period longer than the term leaves a balance at maturity.

Does the loan carry an interest-only period, and for how many months? Scheduled principal during that stretch is zero, which raises the final balance.

What is the payoff balance on the maturity date? That figure comes from the payment schedule and is smaller than the original amount on an amortizing loan.

What share of the original balance does the balloon represent? The share can be set beside the broad 80 to 90 percent range as a reasonableness check.

What income will a new lender size on at maturity? Takeout proceeds follow from that income and the sizing test applied to it.

What net proceeds remain after closing costs? The gross loan amount overstates the cash available to retire the old debt.

How would the loan behave if refinancing alternatives were limited? Delayed payments or default can follow, and a securitized loan can pass those effects to bondholders.
