Create an amortization schedule, and graph the components over time: interest, principal, and balance.
Loan Value = ($1120/$8.84)*1000 = $126,697 And the total payment (as 3% down payment is made)= $126,697/(1-0.03) = $130,615 / Loan Value = ($400/$8.84)*1000 = $45249 And the total payment (as 10% down payment is made) = $45,249/(1-0.1) = $50,277?
