Guarantor Structure & Protecting Parents' Equity

Property lawyer Kathleen Chu had just laid out the legal traps; broker Julianne Zammit came on to translate them into lending reality — because the fine print and the bank's rules are two halves of the same decision. Her focus: getting first-home buyers in without putting their parents' world on the line.
A family guarantee can clear the deposit hurdle and skip costly lenders insurance — but it's a security guarantee, not an income one, so you still have to afford the whole loan. Done right it's capped (usually 20% against the parents' home) and released the moment your property reaches an 80% loan. Get a finance clause too: an auction runs with none, and the bank still has to value the place.
From there it's all structure — keeping each property on its own loan and offset so nothing's tangled, knowing when interest-only beats principal-and-interest, and understanding that the setup you choose at the start decides how much freedom you have later. It isn't glamorous. It's the difference between a portfolio that moves and one that's stuck.

Gold Nuggets From The Episode
Gold Nugget 1: A guarantee is your parents' security, not their income
"Lenders take a roughly 20% security guarantee against the parents' home."
You still have to afford the full loan yourself — the guarantee only covers the deposit gap.
Families fear they're on the hook forever; in fact it's released as soon as your property hits an 80% loan.
Gold Nugget 2: Hardly any major bank does SMSF loans anymore
"Self-managed super fund lending has moved to second-tier lenders."
Residential is about 80% and can't be owner-occupied; commercial is around 70% and can be leased to your own business.
Some lenders quietly restrict SMSF loans by postcode, especially in regional areas.
How a $120k cap protected the parents' home
Real-World Case StudyA young Sydney couple wanted to buy a $600k apartment but had only $15k saved — not enough to avoid LMI.
A bank advisor suggested a standard guarantee that put the parents' $1.5M home on the hook for the full $585k loan.
Instead, the guarantee was capped at $120k (20%). The parents' exposure was limited to that, and the apartment itself covered the rest.
Bought with no LMI, the parents' risk capped at $120k — and released after two years.
