Why would anyone get a loan with a prepayment penalty? Some lenders offer very low (and therefore tempting) interest rates in exchange. Also, some borrowers agree to loans with penalties if they have bad credit and it’s the only way they can get the loan. Mostly, a prepayment penalty is a financial decision. There are situations where accepting a prepayment penalty on a loan can save you thousands of dollars in interest.
Looking back at the flood of foreclosures since the housing crash, it’s clear that many borrowers didn't fully understand the terms of the mortgages they signed. According to one study, 35 percent of ARM borrowers did not know if there was a cap on how much their interest rate could rise [source: Pence]. This is why it’s essential to understand the terms of your mortgage, particularly the pitfalls of “nontraditional” loans.
