The interest rate gets the attention, but the structure of a commercial real estate loan often determines whether an investment succeeds or stalls.
Investors moving from residential rentals into commercial property often bring a 30-year fixed mortgage mindset with them. Commercial real estate debt works differently. Loans are shorter, payments may not fully pay off the balance, personal liability can hinge on a few clauses, and paying off early can cost hundreds of thousands of dollars. The rate on the term sheet matters, but the structure around it frequently matters more.
Two numbers define the shape of a commercial loan, and they are rarely the same. The term is how long the loan lasts before the remaining balance comes due. The amortization is the schedule used to calculate the monthly payment, as if the loan would be repaid over that period.
A typical structure might be a 10-year term on a 25-year amortization. Payments are set as though the borrower has 25 years to repay, which keeps them affordable. But after 10 years, the lender wants the remaining balance back, and that balance is still large.
Some loans also include an interest-only period at the start, during which no principal is repaid. That boosts early cash flow but leaves the full original balance outstanding when amortization begins or the loan matures.
Consider an illustrative $2 million loan at a 6.5% fixed rate with a 10-year term. The table shows how the amortization schedule changes both the payment and the balance due at maturity.
| Amortization | Monthly payment | Annual debt service | Balloon after 10 years |
|---|---|---|---|
| Interest-only | $10,833 | $130,000 | $2,000,000 |
| 30 years | $12,641 | $151,696 | $1,695,523 |
| 25 years | $13,504 | $162,050 | $1,550,227 |
| 20 years | $14,911 | $178,938 | $1,313,230 |
The trade-off is clear. The interest-only structure produces the lowest payment but leaves the entire $2 million to refinance or repay. The 20-year schedule costs nearly $49,000 more per year in debt service but cuts the balloon by close to $690,000.
For a property with $200,000 of net operating income, those choices also move the debt service coverage ratio. Interest-only produces a DSCR of about 1.54, while the 20-year schedule produces about 1.12, which may fall below a lender's minimum.
Almost every commercial loan with a term shorter than its amortization ends in a balloon payment. Few borrowers write a check for it. Instead, they refinance or sell. That makes the balloon a bet on conditions years in the future: interest rates, property values, the property's income and lender appetite all have to cooperate.
When they do not, the consequences can be severe. If rates are higher at maturity, the same income may support a smaller new loan. If values have fallen, the new loan-to-value limit may not cover the old balance. Either way, the owner may need to inject cash, negotiate an extension or sell under pressure.
A balloon payment is not a distant formality. It is the date the market grades your original loan structure.
At acquisition, model the refinance you will need at maturity. Assume a higher rate and a somewhat lower value than today, and check whether the property's income would still support a loan large enough to retire the balloon. If not, consider a longer term, slower interest-only burn-off or lower leverage.
Recourse determines what the lender can pursue if the loan defaults and the property does not cover the debt.
Non-recourse rarely means no personal exposure at all. Nearly every non-recourse loan includes carve-outs, often called bad-boy provisions, backed by a guarantee from the sponsor. Common triggers include fraud, misapplying rents or insurance proceeds, unauthorized transfers of the property, voluntary bankruptcy filings and environmental problems. Some carve-outs create liability only for the lender's losses, while more serious violations can convert the entire loan to full recourse. Read these clauses with an attorney before signing the guarantee.
Commercial lenders price loans expecting to earn interest for the full term. Prepayment provisions protect that expectation, and they vary widely in cost.
The right structure depends on your plan. A value-add investor expecting to sell in three years should avoid heavy yield maintenance, even if it means a slightly higher rate. A long-term holder may happily accept defeasance for better pricing.
Comparing commercial loans on rate alone misses most of the risk. Before signing, line up the term with your business plan, model the balloon under less favorable conditions, understand exactly when personal liability can be triggered and calculate what an early exit would cost. A lender's term sheet is negotiable more often than first-time commercial borrowers assume. Review the final loan documents with an experienced real estate attorney, and ask your CPA how the structure fits your broader tax picture.
