Refinancing may be undertaken to reduce interest
costs (by refinancing at a lower rate), to pay off other debts,
to reduce one's periodic payment obligations (sometimes by taking
a longer-term loan), to reduce risk (such as by refinancing from
a variable-rate to a fixed-rate loan), and/or to liquidate some
or all of the equity that has accumulated in real property during
the tenure of ownership.
In essence, refinancing a mortgage or other type
of loan can lower the monthly payments owed on the loan either
by changing the loan to a lower interest rate, or by extending
the period of loan, so as to spread the re-payment out over a
long period of time. The money saved can be used to pay down the
principal of the loan, thus further reducing payments. Alternately,
refinancing can be used to transform available equity in one's
house into ready cash, available for other purposes or expenses.
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 prime rates used to calculate them. By refinancing
an adjustable-rate mortgage or so-called "Balloon" mortgage
into a fixed-rate one, the risk of interest rates increasing dramatically
is removed, thus ensuring a steady interest rate over time.
Finally, refinancing a loan or a series of debts
can assist in paying off high-interest debt such as credit card
debt, with lower-interest debt such as that of a fixed-rate home
mortgage. The net savings between the two interest rates can then
be applied either towards further paying down the debt, or other
purposes In addition, non-tax deductable debt, such as credit
card or car loan debt, can be transformed into tax-deductable
debt such as home mortgage debt, potentially lowering one's taxes
or shifting one into a more advantageous tax bracket.
