Given:
- Annual salary of the President = $400,000
- Property tax = $50,000 annually
- Home insurance = $15,000 annually
- Down payment = $35,000
First, let's calculate the total monthly housing expenses:
Total Monthly Housing Expenses = Monthly Mortgage Payment + (Property Tax / 12) + (Home Insurance / 12)
Total Monthly Housing Expenses = Monthly Mortgage Payment + ($50,000 / 12) + ($15,000 / 12)
Total Monthly Housing Expenses = Monthly Mortgage Payment + $4,166.67 + $1,250
Total Monthly Housing Expenses = Monthly Mortgage Payment + $5,416.67
Now, let's calculate the Monthly Gross Income:
Monthly Gross Income = Annual Salary / 12
Monthly Gross Income = $400,000 / 12
Monthly Gross Income = $33,333.33
Now, using the Total Expense Ratio (TER) of 28%, we'll find the Monthly Mortgage Payment:
Monthly Mortgage Payment = TER * Monthly Gross Income - $5,416.67
Monthly Mortgage Payment = 0.28 * $33,333.33 - $5,416.67
Monthly Mortgage Payment = $9,333.3324 - $5,416.67
Monthly Mortgage Payment ≈ $3,916.66
So, the president's family can afford a monthly mortgage payment of approximately $3,916.66.
