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.
Loan amount = Price of Duplex - Down payment = $800,000 - $50,000
= $750,000
Quoted APR = 12% semi-annual compounding
Calculating the APR compounded monthly from semi-annual compounding using EAR formula:-
where, r1 = Interest rate compounded monthly
m1 = no of times compounding in a year = 12
r2 = Interest rate compounded semi-annually = 12%
m2 = no of times compounding in a year = 2
Taking 12-root on both sides,
r1 = 11.710548%
So, APR compounded monthly is 11.710548%
Now, Calculating the Outstanding Loan Balance today after 20 monthly payments:-
Where, P = Loan amount = $750,000
r = Periodic Interest rate = 11.710548%/12 = 0.975879%
n= no of periods = 30 years*12 = 360
m = no of loan payments already made = 20 months
Outstanding Loan Balance Today = $744,973.65
- Sale Value of property = $815,000
Amount left for down-payment of another property after paying off loan = $815,000 - $744,973.65
Amount left for down-payment of another property after paying off loan = $70,026.35
