Speak to a tax lawyer.. either donation staggered over a few years or setup a trust(if total value exceeds x million) where parents are the main benefactors but this does come with annual accounting costs. There is no transfer duty cost on a trust and might be good going forward? Though most of the tax benefits and debt risk is reduced due to abuse.
Keep in mind this would mean donating 100k per annum on a loan you take out which might not be the most efficient if you aren’t contributing too to reduce the cost of the loan and carries risk if something happens prior to completion.
The South African Revenue Services (SARS) has issued a clarification note around donations and the taxes that apply.

I’m pretty sure you can receive a max of R100k? Not sure.
People(my parents did so too) usually do this sort of thing as part and parcel of their estate and retirement planning wherein they phase in donations and estate trusts to reduce the inheritance tax payable.
Ps. This is where a TFSA account for a kiddy works phenomenally well.. but the gov control there of is a slight issue.
