The main risks of an interest-only mortgage include significant payment shock when the interest-only period ends, no equity buildup during the initial term, and the potential for negative equity if property values decline. Borrowers face higher long-term costs, risks from adjustable interest rates, and the danger of being unable to repay the principal lump sum.
The biggest drawback of an interest only mortgage is that you don't pay off the loan as you go. This means you have to find another way to do this – you can't just forget about it.

One major risk is that your monthly payments could increase significantly at the end of the interest-only period when you are required to start paying both principal and interest. Additionally, if your property's value decreases, you could find yourself underwater on your loan — owing more than the property is worth.
There are also risks involved with getting an interest-only repayment loan. For example, if your home or investment property declines in value during the interest-only period, you could come out with no equity. Meaning, you may end up owing more than the property is worth.
