How do you make a balloon payment on a commercial loan?

[Matt Morand]

I have no real prior knowledge to commercial real estate financing, so I apologize if this is a newbie question, but through what methods is a balloon payment made on a commercial loan? If I buy a multifamily apartment building with 15 year balloon debt, am I expected to refinance to pay the loan? Sell the property? Get a new loan to pay off the old one?
