Financial institutions granting home loans use a loan factor table to determine the monthly repayment on a home loan. The monthly repayment may not exceed the person's disposable income. The table below is a loan factor table that shows the monthly repayments per R1000 on a home loan with interest rates ranging from 7% to 8,75% per annum over 15,20,25 or 30 years. For example, if the home loan is R1000000 at an interest rate of 8,25% over 15 years then the monthly repayment is: R100000010009,70=R9700 per month Determine which period, 20 years or 25 years, at 7,75% interest will generate sufficient funds by means of a home loan to allow Anthony to buy the particular property and adhere to the NEC requirements regarding disposable income. 2.4 Anthony is fortunate enough to be granted a home loan for the full remaining amount of the selling price and on 31st July 2022 he makes the first payment on the loan.
