House Appreciation and Mortgage Payments | ||||||||
Say that you purchase a house for $400,000 by getting a mortgage for $320,000 and paying a $80,000 down payment. | ||||||||
A. If you get a 20-year mortgage with a 4 percent interest rate, what are the monthly payments? | ||||||||
B. What would the loan balance be in ten years? | ||||||||
C. If the house appreciates at 6 percent per year, what will be the value of the house in ten years? | ||||||||
D. How much equity do you have in the house after ten years? | ||||||||
E. How much is the house worth after twenty years, when the mortgage is paid off? | ||||||||
A
PVOrdinary Annuity = C*[(1-(1+i/(f*100))^(-n*f))/(i/(f*100))] |
C = Cash flow per period |
i = interest rate |
n = number of payments I f = frequency of payment |
320000= Cash Flow*((1-(1+ 4/1200)^(-20*12))/(4/1200)) |
Cash Flow = 1939.14 |
Using Calculator: press buttons "2ND"+"FV" then assign |
PV =-320000 |
I/Y =4/12 |
N =20*12 |
FV = 0 |
CPT PMT |
Using Excel |
=PMT(rate,nper,pv,fv,type) |
=PMT(4/(12*100),12*20,,320000,) |

FV = 0 |
CPT PV |
Using Excel |
=PV(rate,nper,pmt,FV,type) |
=PV(4/(12*100),12*10,,PV,) |
C
Future value = present value*(1+ rate)^time |
Future value = 400000*(1+0.04)^10 |
Future value = 592097.71 |
Using Calculator: press buttons "2ND"+"FV" then assign |

PMT = 0 |
CPT FV |
Using Excel |
=FV(rate,nper,pmt,pv,type) |
=FV(0.04,10,,-400000,) |
D
Equity = FV-loan outstanding = 592097.71-191529.2
=
400568.51 |
E
Future value = present value*(1+ rate)^time |
Future value = 400000*(1+0.06)^20 |
Future value = 1282854.19 |
Using Calculator: press buttons "2ND"+"FV" then assign |
