STEP 1

1. The buyer's monthly salary is 1,815.<br/>2.Thebuyerhasmonthlybillstotaling1,815.<br />2. The buyer has monthly bills totaling 245.
3. The home costs 89,000.<br/>4.Theloantermis30yearswitha989,000.<br />4. The loan term is 30 years with a 9% interest rate.<br />5. The monthly payment should not exceed 28% of the buyer's gross monthly income.<br />6. The table provides the monthly cost to finance 1,000 at various interest rates and terms.

STEP 2

1. Calculate the maximum affordable monthly mortgage payment.
2. Determine the monthly cost per $1,000 financed using the table.
3. Calculate the total loan amount that can be financed.
4. Calculate the necessary down payment.

STEP 3

Calculate the maximum affordable monthly mortgage payment using 28% of the buyer's gross monthly income:
Maximum Payment=0.28×1,815=508.20\text{Maximum Payment} = 0.28 \times 1,815 = 508.20
Subtract monthly bills from the maximum payment:
Affordable Mortgage Payment=508.20245=263.20\text{Affordable Mortgage Payment} = 508.20 - 245 = 263.20

STEP 4

Using the table, find the monthly cost to finance $1,000 for a 30-year loan at 9% interest:
Monthly Cost per $1,000=8.05\text{Monthly Cost per } \$1,000 = 8.05

STEP 5

Calculate the total loan amount that can be financed based on the affordable mortgage payment:
Loan Amount=263.208.05×1,00032,684.47\text{Loan Amount} = \frac{263.20}{8.05} \times 1,000 \approx 32,684.47

STEP 6

Calculate the necessary down payment:
Down Payment=89,00032,684.47=56,315.53\text{Down Payment} = 89,000 - 32,684.47 = 56,315.53
Round the down payment to the nearest hundred dollars:
Rounded Down Payment=56,300\text{Rounded Down Payment} = 56,300
The amount of the down payment necessary is:
56,300\boxed{56,300}
