This is known as amortization because the debt is gradually reduced. Negative amortization can occur when the installment payments do not cover all the interest due each month. This unpaid interest is added on to the principal that is owed, resulting in a debt that increases, rather than decreases. Then the size of your debt could increase to the point where it would exceed the equity in your home. Sadly, you could sell your home and not be able to repay what you owe.
Most professionals advise buyers to avoid a negatively amortized loan.
