Sabrina has decided to invest her savings in real estate. 20 months ago, she purchased a duplex for $800,000. She could afford to make a down-payment of $50,000. The bank gave her a 30-year mortgage with constant monthly payments at a quoted APR of 12% with semi-annual compounding. Today, (after making her last monthly payment to the bank) Sabrina was able to resell her property for $815,000. With the money she has left after paying the bank for the remaining mortgage, Sabrina will make a down-payment on a new property. What is the down-payment she can make on this new property? Hint: First find the monthly payments she must make.
a. $73,922.57
b. $60,718.76
c. $45,320.68
d. $70,026.35
e. $58,026.36
Answer : d. $70,026.35
Complete calculations below :
Loan Amount = Property value - Down Payment = 800,000 - 50,000 = $750,000
Life of loan = 30 years
Rate of interest = APR 12% compounded semi annually
Calculations :
Interest per month = $7,547.91
Therefore, total payment in 20 months = 7,547.91*20 = 150,958.20
Balance at the end of 20 months :

Amount required to pay off the loan in full = 744973.65 (assuming no other cost)
Amount from sale = 815,000
Balance= 815,000 - 7,44,973.65 = 70,026.35
