If you anticipate rates to drop before your ARM rate resets, securing an ARM now, and after that refinancing to a lower rate at the correct time could conserve you a significant amount of money. Bear in mind, however, that if you refinance during the intro rate duration, your lending institution may charge a fee to do so.


- You're starting your profession. Borrowers soon to leave school or early in their professions who know they'll make considerably more with time might also gain from the initial savings with an ARM. Ideally, your increasing earnings would offset any payment boosts.


- You're comfy with the risk.

"A borrower may perceive that the month-to-month savings in between the ARM and fixed rates deserves the danger of a future boost in rate," says Pete Boomer, head of home mortgage at Regions Bank in Birmingham, Alabama.
