With interest only mortgages only the interest is actually paid off with each mortgage payment. The borrower also takes out at the same time, an alternative 'repayment vehicle' (method of paying off the mortgage) such as an ISA, pension plan or an endowment policy.
The monthly repayments do not
repay any of the outstanding capital balance. So it
is important that the repayment vehicle payments are
maintained, otherwise it will not be possible to pay
off the mortgage at the end of the term.
Endowment Policies - This is the most common type of
interest only mortgage which also provides life
assurance cover and a fixed payment for investment.
The fixed payments are based on the amount of the
loan together with the mortgage term and are
designed so that, at maturity, the amount invested
and earnings are enough to pay off the mortgage.
However - there is no guarantee that, when the
endowment matures and 'pays out', the balance will
be sufficient to repay the mortgage, the funds
success depends on the interest rates.
