Answer: 8%
Step-by-step explanation:
Fair value = $708,769
Down payment will be made so only the amount net of the down payment will be paid periodically.
= 708,769 - 172,000
= $536,769
Present value of Annuity interest factor for payment = 536,769/66,179
= 8.11087
No. of periods = 2 * 5years = 10 semi annums
Look at the Present value of interest factor of Annuity (PVIFA) table and find the interest rate that corresponds to 10 periods and gives an interest factor of 8.11087.
That interest rate is ⇒ 4%
As this is a semi-annual rate, the annual rate is;
= 4% * 2
= 8%
