After not being able to save before, Ari calculates that his new job will enable him to start putting aside some money. He wants to buy a flat five years from now, knowing that he will need a deposit of at least 15,000 in order to do so. He has just received 2500 in his late grandmother's will. 2.1 If he saves the 2500 lump sum plus 150 per month, what rate of return will Ari need to reach his target of 15,000 after 5 years? 2.2 Ari has seen that shares (equities) in a particular company have given a 9 per cent return over the past five years. Give two reasons why, to get a similar return over the next 5 years, it might not be a good idea to put all his savings for the deposit into buying this company's shares. 2.3 Ari can get a higher rate of return on his savings, enough to reach his target deposit, if he commits to a savings plan that runs for 10 years (rather than 5) with no scope for early withdrawals. Identify two financial disadvantages of waiting an extra 5 years before offering the deposit to buy a first home. 2.4 How will Ari's efforts to save for a deposit be affected if there is a sharp rise in interest rates which causes a fall in house prices
