Explanation:
#1
Original price of the house = $125,000
Balance after the 20% down payment = $125,000 -(0.20*125,000) = $100,000
Loan amount borrowed = $100,000
Use the loan amount as the present value to solve for monthly payments. On a financial calculator, input the following;
PV = -100,000
Monthly interest rate ; I = 6%/12 = 0.5%
Duration of loan(in months) ; N = 20*12 = 240
Future value ; FV = 0
then compute monthly payment ; CPT PMT = $716.43
Total amount paid back altogether = 716.43*240 = $171,943.20
Total interest paid back = $171,943.20 - $100,000 = $71,943.20
#2
Total price of the house = $210,000
Balance after the 30% down payment = $210,000 -(0.30*210,000) = $147,000
Loan amount borrowed = $147,000
Use the loan amount as the present value to solve for monthly payments. On a financial calculator, input the following;
PV = -147,000
Monthly interest rate ; I = 5%/12 = 0.4167%
Duration of loan(in months) ; N = 30*12 = 360
Future value ; FV = 0
then compute monthly payment ; CPT PMT = 789.16
Total amount paid back altogether = 789.16*360 = $284,097.60
Total interest paid back = $284,097.60 - $147,000 = $137,097.60
#3
Original price of the house = $85,000
Balance after the 25% down payment = $85,000 -(0.25*85,000) = $63,750
Loan amount borrowed = $63,750
Use the loan amount as the present value to solve for monthly payments. On a financial calculator, input the following;
PV = -63,750
Monthly interest rate ; I = 6.5%/12 = 0.5417%
Duration of loan(in months) ; N = 15*12 = 180
Future value ; FV = 0
then compute monthly payment ; CPT PMT = $555.35
Total amount paid back altogether = 555.35*180 = $99,963
Total interest paid back = $99,963 - $63,750 = $36,213
#4
Original price of the house = $135,000
Balance after the 40% down payment = $135,000 -(0.40*135,000) = $81,000
Loan amount borrowed = $81,000
Use the loan amount as the present value to solve for monthly payments. On a financial calculator, input the following;
PV = -81,000
Monthly interest rate ; I = 6.5%/12 = 0.5417%
Duration of loan(in months) ; N = 30*12 = 360
Future value ; FV = 0
then compute monthly payment ; CPT PMT = $512
Total amount paid back altogether = 512*360 = $184,320
Total interest paid back = $184,320 - $81,000 = $103,320
