What will their down payment be?

Down payment = 20% of the purchasing price

= 300,000 * 20%

= $ 60,000

2) What will the cost of insurance be per month?

Cost of insurance = 1/2 * 1% of 300,000

= $ 1,500

Per month = 1500/12

= $ 125

3) What will their taxes be per month?

Taxes = $3.00 per $100 of assessed value

= 75% of 300,000

Addressed value = 300,000 * 75% = $ 225,000

Per $ 100 = 2250 * 3 = $ 6750 per year

Therefore, the monthly tax = 6750/12

= $ 562.5

4) What will their principal and interest be per month?

The loan term = 30 years

If the Principle = 300,000 – 60,000 = $ 240,000

Interest = ARM Interest of Principle Amount

= 4.5%/12 months

= 0.00375

Monthly principle and interest payment = M

M = 240,000 [0.00375 (1+0.00375)^360/(1+0.00375)^360 – 1]

M = $ 1215.97

5) What is their total monthly payment going to be including everything?

Therefore the total monthly payment;

= Principle & Interest + Taxes + Insurance

= 1215.97 + 562.5 + 125

= $ 1903.472
