Your reserve balance will amortize down over the term of the loan as well. It is necessary to be NCA compliant for the bank. Otherwise you could be, say, R1m in advance the day before the loan matures and withdraw the entire R1m and then you would owe it back the next day which would breach the "max instalment of 30% of gross income" rule. So effectively your reserve balance will be equal to the theoretical amortized value/outstanding balance at this point in time (i.e. assuming you've made no additional payments) minus your actual outstanding balance.Thanks, yeah I gather that's what happens when it's fully paid off. The monthly fee is to keep the facility open.
Dumping this lumpsum in there brings it down from 16 years to just over 6 years. But technically it would be paid off in 4.5 years when the reserve balance = loan balance.

What tripped me up was my reserve balance decreasing without drawing anything from it...
Practically, what I've seen happen is that the available balance will decrease by the full instalment on the payment date but increase back up to the correctly amortised value a few days later. e.g. will drop from R1m to R980k then will go back up to R998k a few days later.
