wat is the difference between a hybrid option arm and an adjustable mortgage?

Hi, I'm an old visitor to this forum. I hope I can give exact answer to your question.

Hybrid Option Arm gives you options for payment, and its fixed for 5 years usually.
1: Minimum Payment (deferred payment goes to principal)
2: Interst only payment
3 30 yea fixed
4 15 year fixed

Adjustable is usually fixed for certain amount of time, 3,5,7,10 years at a certain rate, and after the years are up the rate becomes adjustable, which will change depending on the market.
