I would like claification on the following;
I have a house mortgage, interest is calculated daily and charged to
the loan on the last day of each month. That part I am happy with.
I make regular payments (fortnightly) reducing loan balance, they charge
interest, increasing loan balance.
My question is this:
If I redraw (take out excess payments) they debit my loan (increase) for
amount withdrawn.
They also charge interest on amount withdrawn for balance of days remaining
in the month (ie redraw on day 10 charge interest for balance of days
left in month ie; 20) then debit this interest to the loan (increase by interest
amount).
Scenario 1 Loan amount $200,000
Calculate interest daily and charge to loan monthly
and increase loan by determined amount.
Reduce loan by loan repayments.
Fairly straightforward and normal proceedure.

Scenario 2 As above but redraw an amount of $1000 in the month
only difference loan amount will increase by 1000 and
higher interest amount is calculated for that month.
Scenario 3 My situation;
As above for scenario 1/2 except that on the day of
withdrawal interest is charged on the $1000 for balance of
days owing in the month
loan amount 200.000
Payment day 7 1000 199.000
Payment day 14 1000 198.000
Redraw day 21 1000 199.000
Interest 25 199.025

( End of month)
Interest 1000 200.025
I have been charged interest on day 21 on $1000 ($25)
The $1000 increased loan balance and interest is charged
at end of month ( I have now been charged interest twice
on the $1000) and finally the $25 charged on day 21 is added
to the loan (and increases the loan) and I am charged interest
on the interest.

Do I have a problem. How do I solve this problem.
Your input is welcome
