A couple are buying a house and have taken out a special ‘First-time buyer’ mortgage,
which allows for lower payments in the earlier years.
The mortgage, of £300,000, has a term of 30 years. For the first 6 months, no
repayments are made, although interest still accrues on the loan. Interest-only
repayments are due from this point until the end of the third year. After the end of the
third year, and up to the end of the term, level repayments are due, set at a level such
that the mortgage will be repaid in full at the end of the 30-year term.
All repayments are made monthly in arrears. Interest is charged at an effective rate of
4.5% p.a.
(i) Calculate the amount of each monthly repayment, without using a scenario
solving tool such as Goal Seek or Solver.
(ii) Construct the loan schedule for the mortgage.
The conditions of the loan permit borrowers to make additional payments in order to
reduce the term of the mortgage. These additional payments can be made once each
year, excluding the first year, subject to a maximum of 10% of the outstanding capital
amount, as determined at the beginning of each year of payment. The original
repayments, including the repayments in the first 3 years, will not change but the term
of the mortgage will reduce.
The original repayment schedule will remain unchanged except for the term.
The couple decide to make additional payments to reduce the term of the mortgage as
much as possible.
(iii) Determine the shortest possible term that can be achieved in this way.
Are additional payments deducted before calculating interest? or I missed some condition?
