There are two related questions in this mortgage problem. Must
respond to both. Suppose you are buying a house that costs
$400,000. You put 25% as down payment and the rest you get 15-year
mortgage at 4.6% with your 35th Bank.
i. What is your ending balance at the end of year
two.
ii. Suppose you are planning to pay off the remaining debt
as “balloon payment at the end of year 10 with 1.5% prepayment
penalty. How much money do you need to pay to
35th Bank to own your
house completely at the end of year 10?
Answer (i):
Cost of house = $400,000
Down payment = 400000 * 25% = $100,000
Loan amount = PV = 400000 - 100000 = $300,000
NPER in months = 15 * 12 = 180 months
Monthly interest = RATE = 4.6%/12
Monthly payment = PMT (rate, nper, pv, fv, type)
= PMT (4.6%/12, 180, -300000, 0, 0)
= $2310.34178
Ending balance at the end of year two = PV of remaining monthly installments
Remaining NPER = 180 - 2*12 = 156
PV of remaining monthly installments = PV(rate, nper, pmt, fv, type)
= PV(4.6%/12, 156, -2310.34178, 0, 0)
= $270,888.94
Ending balance at the end of year two = $270,888.94
Answer (ii):
Ending balance at the end of year 10 = PV of remaining monthly installments
Remaining NPER = 180 - 10*12 = 60
PV of remaining monthly installments = PV(rate, nper, pmt, fv, type)
= PV(4.6%/12, 60, -2310.34178, 0, 0)
= $123623.55
Ending balance at the end of year 10 = $123,623.55
Prepayment penalty = 1.5%
Money do you need to pay to bank = 123623.55 +123623.55 *1.5% = $125,477.90
Money do you need to pay to bank at the end of Year 10 = $125,477.90
