Adjustable-rate mortgages (ARMs) are loans with interest rates that change. ARMs may start with lower monthly payments than fixed-rate mortgages.
There may be a few things to consider when deciding on an adjustable mortgage rate:
At the time of your initial finance, adjustable rate mortgages are initially lower than a fixed rate mortgage, but will increase over a few years. Adjustable rate mortgages are good if your immediate financial situation requires a lower payment or if your credit needs improvement and your looking to get yourself established in a mortgage.
Once someone establishes a mortgage payment history, and if fixed interest rates have gone down, borrowers usually refinance into a fixed interest rate.
