Answer:

1. The amount of the house that was financed is;

= 300,000 * ( 1 - 20%)

= $240,000

The amount that will be paid per month is an annuity with the present value being $240,000.

Period = 30 years * 12 months = 360 months

Interest = 4%/12

240,000 = Annuity * (1 - ( 1 + r) ^-n)/r

240,000 = Annuity * ( 1 - ( 1 + 4%/12) ^-n) / r

Annuity = 240,000/209.46

Annuity = $1,145.80

2. Interest Portion;

= Amount Owed * Interest rate

= 240,000 * 4%/12

= $800

3. Principal portion = Monthly payment - Interest

= 1,145.80 - 800

= $345.80

4. Balance after first payment

= Principal - Principal repayment

= 240,000 - 345.80

= $‭239,654.2‬0
