Balloons and refinancing risk on commercial property

By Klark Sparks  ·  September 14, 2026  ·  6 min read

The short answer

Many conventional commercial mortgages amortise over a long period but mature far sooner, leaving a balloon payment. That schedules a refinance you will have to complete under whatever conditions exist at the time. Know your maturity date, diary it years ahead, and understand that SBA 504 largely removes this risk.

A commercial mortgage can look like a residential one and behave completely differently, and the difference is usually buried in the maturity date.

Amortisation is not term

A loan can amortise over twenty-five years — meaning the payment is calculated as though it will take that long to repay — while maturing in seven. At maturity the remaining balance falls due in one lump.

The payment feels like a long-term mortgage. The obligation is a seven-year loan with a very large final payment.

Ask two separate questions of any commercial mortgage offer: over what period is the payment calculated, and when does the loan mature? If those numbers differ, you have a balloon, and you should know its size.

What you are committing to

A refinance, on a date fixed now, under conditions nobody can forecast. At that point four things will matter and none is fully within your control: prevailing rates, the property’s value, your business’s financial condition, and lender appetite for your sector.

Most of the time it is fine. The businesses that get hurt are the ones where several of those move the wrong way at once — a softer market, a weaker trading year, and a lender that has stepped back from the sector.

Planning for it properly

  1. Diary the maturity date the day you close, with a reminder eighteen to twenty-four months ahead.
  2. Start the refinancing conversation at that reminder, not at twelve months and certainly not at six.
  3. Keep the property maintained. Deferred maintenance shows up in the appraisal at exactly the wrong moment.
  4. Keep the books clean throughout. A refinance is underwritten on recent performance, so the two years before maturity matter more than the five before them.
  5. Build equity deliberately. Paying down principal reduces what has to be refinanced and improves how the request looks.

The 504 alternative

The development company portion of an SBA 504 typically carries a long fixed term, which means a substantial share of the debt has no balloon and no rate reset for decades. The bank portion has its own terms and may still mature sooner, so it is not a complete elimination of the risk — but it materially reduces it.

For a business that intends to occupy a building for twenty years, removing most of a forced refinance is worth more than a small rate advantage. That is the argument for 504 that gets least attention and probably deserves most.

If maturity is approaching and things are difficult

Talk to your existing lender early. Extensions and modifications are more available to a borrower who raises it eighteen months out than to one who appears three weeks before maturity with a problem.

And explore alternatives in parallel rather than sequentially. Assuming your current lender will simply roll it over is a common and occasionally expensive assumption — their appetite for your sector may have changed for reasons that have nothing to do with you.

Common questions

Why do commercial lenders use balloons?
They limit how far ahead the lender commits, on rate and on exposure to a single borrower and sector. It is a risk management tool for them, and it transfers refinancing risk to you.
Can I get a commercial mortgage with no balloon?
SBA 504 removes most of it through the long fixed development company portion. Fully amortising conventional commercial loans exist but are less common, particularly at smaller loan sizes.
What happens if I cannot refinance at maturity?
You negotiate an extension, sell, or face enforcement. Extensions are frequently available to borrowers who engage early, which is the entire argument for starting the conversation well ahead.
How far ahead should I start?
Eighteen to twenty-four months. That is enough time to improve your position, shop properly, and handle a surprise without being forced into whatever is offered.
