Calculate the total value of monthly instalments for Option 1, and the monthly interest rate for Option 1.

The term agreement for Option 1 is 10 years.

The term agreement in months for bond payment option one is $\boxed{\text{120 months}}$.

2.2.2

The annual interest rate is $10.75\%$.

The interest rate per month, rounded to one decimal place, is $\boxed{0.9\%}$.

2.2.3

Monthly instalment (Option 1) = R68 033
Once-off costs (Option 1) = R1 600 015

The term in months for Option 1 is 120 months (from 2.2.1).

The total cost of the house if Mpho uses bond payment option one is $\boxed{\text{R}9\,763\,975}$.

2.2.4

Purchase Price = R5 990 000

Mpho will be paying approximately $\boxed{63.00\%}$ more than the purchase price.

2.2.5 & 2.2.6

Principal ($P$) = R350 000
Interest rate ($r$) = 17% = 0.17
Time ($t$) = 3 years

The amount R528 500 is already rounded to the nearest one hundred rand.
The amount Mpho pays back, rounded to the nearest one hundred rand, is $\boxed{\text{R}528\,500}$.

2.2.7

Term agreement (Option 2) = 15 years = $15 \times 12 = 180$ months.
Monthly instalment (Option 2) = R55 935.

Term agreement (Option 3) = 20 years = $20 \times 12 = 240$ months.
Monthly instalment (Option 3) = R50 659.

Mpho stated that the difference is less than R2 000 000.
Our calculated difference is R2 089 860.
Since R2 089 860 is not less than R2 000 000 (it is greater), Mpho's statement is invalid.
Mpho's statement is $\boxed{\text{invalid}}$.
