Generally, the option ARM mortgage has a considerably lower interest rate for the initial few months.
Initially, you might be paying one or two percent on the loan before the interest rate starts to adjust according to the market.
The monthly payment paid by the borrower for the first year depends on the initial rate of the loan.
If the borrower chooses the limited payment option, the unpaid interest gets added to the loan balance which increases the total loan amount you owe to the lender.
This process is also known as negative amortization. This means that your loan balance keeps increasing even after you make the minimum payments as these payments are insufficient to cover the interest amount.
Due to the negative amortization, the property could end up being underwater, which means that you owe more than what your property is worth.
Generally, there is a cap for your payment increase every year in this type of mortgage.
Your mortgage payments are recalibrated every five years depending on the years left on your original loan term.
