A balloon mortgage loan is a mortgage often based on a 30 years amortization schedule with the unpaid balance payment at the end of a specific period of time which could be anywhere between 5-7 years.
The balloon loan mortgage may contain an option to reset the interest rate to the current market and extend the due date if certain conditions are met. Basically, you have low, or no payment for a certain amount of time.
This could be ideal for someone who is either living in the home for a short period or someone who is banking on increasing their income over the next few years. However, if the market is declining this mortgage could be very dangerous.
For example, if you got a mortgage for $200,000 with a 5-year term, this means for the first 5 years your mortgage payments would be amortized according to 30 years mortgage and by the end of 5th year whatever the balance amount is reaming you are expected to pay that in a lump sum.
Some balloon mortgage loans have a reset option which takes effect at the end of the loan.
When the borrower requests for a reset, which meant he wants the lender to automatically recalculate the mortgage at the current interest rate.
However, when no such option has been provided, it could mean that the borrower would either sell the property or refinance the home mortgage before the end of the term.
