Refinancing refers to the replacement of an existing debt obligation
with a debt obligation bearing different terms. The most common consumer
refinancing is for a home mortgage.
Refinancing may be undertaken to reduce interest costs (by refinancing
at a lower rate), to extend the repayment time, to pay off other debts,
to reduce one's periodic payment obligations (sometimes by taking a
longer-term loan), to reduce or alter risk (such as by refinancing from
a variable-rate to a fixed-rate loan), and/or to raise cash for investment,
consumption, or the payment of a dividend. In essence, refinancing can
alter the monthly payments owed on the loan either by changing the loan's
interest rate, or by altering the term to maturity of the loan. More
favourable lending conditions may reduce overall borrowing costs. Another
use of refinancing is to reduce the risk associated with an existing
loan. Interest rates on adjustable-rate loans and mortgages shift up
and down based on the movements of the various indicies used to calculate
them. By refinancing an adjustable-rate mortgage into a fixed-rate one,
the risk of interest rates increasing dramatically is removed, thus
ensuring a steady interest rate over time. This flexibility comes at
a price as lenders typically charge a risk premium for fixed rate loans.
