Big Bank will make Duane Miller a mortgage loan if it meets the 28/36 rule. His annual gross income is $45,000. He has a $675 monthly auto payment and the property taxes & homeowners insurance for a new home will cost $3,000 annually. Big Bank will give him a 30-year mortgage with a 7.5 percent fixed rate. Duane will make a 20% down payment.
As per 28/36 rule, an individual can spend a mximum of 28% of his gross income on his housing debt including housing expenses. And a maximum of 36% of his gross income on total debt which includes housing, car and other debt services.
Annual Gross income = $45,000
Annual Auto payment =$675 per month*12
= $8100
Property taxes & homeowners insurance = $3000 annually
Down-payment = 20%
a). Calculating the maximum purchase price for a home can Duane afford:-
Since, Duane is paying auto debt payments he will be covered in 36% rule.
Maximum debt service amount = Annual Gross income*36%
=$45,000*36%
= $16200
Debt payment available for housing loan = $16200 - $8100 - $3000
= $5100
Monthly home loan payment = $ 5100/12
= $425
Using, the monthly payment to calculate the Home loan amount:-
where, P = loan amount
r = Periodic Interest rate =7.5%/12 = 0.625%
n= no of periods =30yrs*12 = 360
EMI = monthly payment = $425
P = $ 60782.49
Loan amount = $ 60782.49
Down-payment = 20%
Maximum purchase price of home = Loan amount/(1-Down-payment)
= $60782.49/(1-0.20)
= $ 75,978.11
So, maximum purchase price for a home can Duane afford is $ 75,978.11
b). Calculating the maximum purchase price for a home can Duane afford:-
Since, Duane pays off his auto loan thereby eliminating the $675 monthly payments and therafter he has only housing debt payment and its related expenses to pay, thus he will be covered in 28% rule.
Maximum debt service amount = Annual Gross income*28%
=$45,000*28%
= $12,600
Debt payment available for housing loan = $12600 - $3000
= $9600
Monthly home loan payment = $9600/12
= $800
Using, the monthly payment to calculate the Home loan amount:-
where, P = loan amount
r = Periodic Interest rate =7.5%/12 = 0.625%
n= no of periods =30yrs*12 = 360
EMI = monthly payment = $800
P = $ 114414.10
Loan amount = $ 114414.10
Down-payment = 20%
Maximum purchase price of home = Loan amount/(1-Down-payment)
= $114414.10/(1-0.20)
= $ 143,017.62
So, maximum purchase price for a home can Duane afford is $ 143,017.62
