Teaser loans are loans that offer a lower interest rate for an initial period, usually to attract borrowers. After this introductory period, the interest rate increases to a higher or market rate. For instance, a borrower may enjoy a rate of 6% for the first few years, and after that, the rate could rise to 8% or higher for the remainder of the loan term. These loans are often used for home loans and are common in products like adjustable-rate mortgages (ARMs)
