Bullet Loan

Any loan that requires a balloon payment at the end of the term and anticipates that the loan will be refinanced in order to meet the balloon payment obligation.

Investopedia Says:
These loans are riskier because the homeowner's equity in the property doesn't increase over time.

Loan that has a one-time payment of principal and interest at its termination. A bullet loan is similar to a Balloon Maturity loan, with the important difference that a bullet loan, unlike a balloon loan, has no obvious source of repayment. To pay off the bullet loan the borrower may have to refinance at the current rate, liquidate assets, or sell collateral.

Typically a loan with a 5- to 10-year Term and no Amortization. At the end of the term the full amount is due.
Example: Barry borrows $1 million for 5 years at 10% interest to buy commercial Real Estate. If he can't repay the loan or Refinance it when due, he will lose the Property.
