They are great if your market is appreciating, and can be catastrophic if home values are falling.
If your market is doing well, and not showing any signs of collapsing-save your money & go with an IO.
They are also good for home flippers who are vested in more than one property.
If you're careful & don't end up "upside down"(Owing more than the place is worth), they are absolutely awesome.
