Term length is not your amortization
First, a clarification that saves a lot of confusion. Your term is how long your current rate and contract are locked — 3 years, 5 years, etc. Your amortization is how long it takes to pay the mortgage off entirely, usually 25 or 30 years. At the end of each term you renew the remaining balance at whatever rate is available then. So choosing a 3-year vs a 5-year term doesn't change how fast you pay off your home — it only changes how often you revisit your rate. You'll go through several terms over the life of one amortization.
