4 You want to buy a house worth 4500000 and the a down payme
Solution
(a) House Price = $ 4500000, Down Payment = 30 % or 30 % of $ 4500000.
Down Payment Value = 0.3 x 4500000 = $ 1350000
Loan Amount = 4500000 - 1350000 = $ 3150000
(b) Interest Rate = 3.6 % per annum or 0.3 % per month, Loan Tenure = 30 years or 360 months
Let the monthly repayments be $ K
Therefore, 3150000 = K x (1/0.003) x [1-{1/(1.003)^(360)}]
K = $ 14321.33
K = 29.7 % of Monthly Gross Income
Monthly Gross Income = 14321.33 / 0.297 = $ 48219.97
Annual Income = 48219.97 x 12 = $ 578639.64
(c) Value of the House at the end of Year 2034 = 4500000 x (1.003)^(192) = $ 7998188.839
Mortgage Paid = 14321.33 x 192 = $ 2749695.36
Down Payment = $ 1350000
Total Repayment = 1350000 + 2749695.36 = $ 4099695.36
% of House Owned = 4099695.36 / 7998188.839 = 0.5126 or 51.26 % approximately.
