Guarantor home loans in WA: how parents actually help

The honest version of going guarantor

Somewhere in Perth right now, a parent is offering to "go guarantor" for their kid, and neither of them could tell you exactly what that means. Most of what is written about guarantor home loans is either a sales pitch or a horror story. This article is neither. It is a plain explanation of what a family guarantee actually is, what the guarantor is really signing up for, and the questions worth asking around the kitchen table first.

One thing before we start. This is general information, not advice about your situation. A guarantee involves two households, not one, and the guarantor should always get their own independent legal and financial advice before committing. We are not a substitute for that. What we do is structure the lending side properly and work alongside your family's own advisers so that everyone signs with their eyes open.

What a guarantor home loan actually is

Strip away the jargon and the mechanism is simple. The buyer takes out the home loan in their own name and makes every repayment themselves. The parents (or another close family member, depending on the lender's policy) allow the lender to take some of the equity in their own property as additional security for that loan.

That is the whole trick. The parents do not hand over cash, do not go on the loan, and do not make repayments. They pledge part of the value of their home as a backstop, so the lender is looking at two properties standing behind one loan instead of one. With that extra security, the lender can write the loan with a smaller deposit than it would otherwise want, and in many cases without charging lenders mortgage insurance, the premium lenders normally apply when a deposit is on the small side.

For the buyer, the practical effect is speed: years of saving compressed into a settlement date. For the parents, the practical effect is that a slice of their home's equity is now spoken for until the guarantee is released. Both halves of that sentence matter equally.

This is not the First Home Guarantee. They are different things

The naming here is genuinely unhelpful, so let us deal with it head on.

A guarantor home loan (also called a family guarantee or family pledge) is what this article is about: your parents put up part of their own property as security.

The First Home Guarantee is a federal government scheme where the government, not your family, provides a guarantee to the lender so eligible first home buyers can purchase with a small deposit and no lenders mortgage insurance. No family property is on the line. It has its own eligibility rules and price caps, covered properly in our First Home Guarantee WA guide.

If you have a small deposit, the government scheme is usually the first thing to check, because it can deliver a similar outcome without anyone in your family taking on risk. A family guarantee earns its place when that scheme does not fit: the property is over the price cap, the eligibility rules rule you out, or the deposit gap is bigger than the scheme can bridge. Working out which lane you are in is a one-conversation question.

Who can actually be a guarantor?

Shorter list than most families expect. Lenders generally want an immediate family member, and in practice that usually means parents. Some lenders will consider step-parents, grandparents or siblings, but policies differ and the further you move from "mum and dad", the fewer options you have.

Beyond the relationship, the guarantor needs to bring three things. Enough equity in an Australian property to cover the guarantee, with room to spare. A clean credit position of their own. And genuine willingness, evidenced the way lenders expect: independent legal advice before signing, so nobody can later say they did not understand it.

Guarantors close to or in retirement get extra scrutiny, and rightly so. A lender asking hard questions about how a 68 year old would cope if the guarantee were called is doing its job. If the answer is "they would have to sell the house", the structure needs rethinking, not a more relaxed lender.

What the guarantor actually risks

This is the part that gets skated over, so here it is without varnish.

If the buyer stops repaying and the situation cannot be rescued, the lender's first recourse is the property that was purchased. If selling it does not cover what is owed, the lender can call on the guarantee, and the guarantor is liable for the guaranteed amount. Depending on their finances, that could mean paying from savings, borrowing against their home, or in the worst case selling it. That worst case is rare and sits at the end of a long chain of things going wrong, but it is real, and a guarantor who has not understood it has not truly consented.

There are quieter costs too. While the guarantee is in place, the pledged equity is not available for the parents' own plans: topping up their loan, helping another child, downsizing, or borrowing in retirement. A guarantee given cheerfully at 58 can feel very different at 63 when the caravan or the renovation is on the table.

This is why lenders typically require, or at minimum strongly push, guarantors to get independent legal advice before signing, and why we think independent financial advice is worth adding even when it is not demanded. Good structuring reduces these risks. It does not delete them.

Limited guarantees: capping what is at stake

Here is the piece of good news that most families do not know exists. A guarantee does not have to cover the whole loan.

Modern family guarantees are usually limited guarantees: the guarantor's liability is capped at a specific dollar amount, generally just enough to bridge the gap between the deposit the buyer has saved and the level of security the lender needs. The parents are never on the hook for the full loan, only for that defined slice, and the number is written into the guarantee documents before anyone signs.

The size of that slice depends on the purchase price, the deposit, and the lender's policy, so we will not quote a formula here. The principle is what matters: a properly structured guarantee is as small as it can be, clearly capped, and designed from day one to be released. If a proposed guarantee is unlimited, or nobody can tell you the exact figure, stop and ask why.

How much can you borrow with a guarantee?

The honest general answer: depending on the lender's policy, a properly structured family guarantee can support borrowing up to the full purchase price, and in some cases the purchase costs such as stamp duty on top. That is how buyers with strong incomes but small deposits get in years earlier, and it is also why the servicing question matters so much: the guarantee removes the deposit hurdle, not the repayments.

A rough illustration of the shape, not a quote and not advice. Suppose a $500,000 purchase with $25,000 saved. Without support, most lenders would want a much bigger deposit or would add lenders mortgage insurance. With a limited family guarantee bridging the security gap, the loan can be written for the full amount needed, and the parents' exposure is capped at the bridge amount, not the whole loan. The exact figures depend on the price, the lender and the structure, which is precisely the conversation we have before anyone commits to anything.

If you want to sanity-check your own numbers first, our borrowing capacity calculator and repayment calculator give you a starting point. The guarantee structure is what a broker adds on top.

The other figure to pin down early is transfer duty, since whether the guarantee needs to cover purchase costs depends on it. Our WA stamp duty calculator shows the current number for your target price, with the first home buyer concessions applied where eligible.

How the guarantor gets released

A family guarantee is meant to be temporary scaffolding, not a permanent fixture. It can come off once the loan stands securely on the purchased property alone. That point arrives from two directions, usually both at once: the buyer pays the loan down, and the property's value rises. When the numbers work, the buyer applies to the lender for a release, the lender orders a valuation and reassesses the loan, and if it is satisfied, the guarantee is discharged and the parents' title is unencumbered again.

The catch is that release is almost never automatic. Lenders do not ring you up to offer it. Someone has to run the numbers, judge the timing, and make the application. When we set up a guarantor loan we treat the release as part of the plan, not an afterthought, and start the conversation as soon as the position supports it. Parents deserve a defined exit, not an open-ended favour.

The family conversation nobody has

Most guarantee arrangements are agreed in a single warm conversation and never discussed again. That is a mistake. Before anything is signed, answer the awkward questions while everyone still likes each other:

• What happens if the repayments stop? Job loss, illness and separation happen to good people. Who says what to whom, and how quickly?
• What are the parents' plans for the next five to ten years? Downsizing, retiring, renovating, helping a sibling. A guarantee can quietly block all of them.
• Is this fair across the family? Resentment compounds faster than interest.
• When exactly does the guarantee come off? Agree the intention up front and put a review date on it.
• Does anyone feel obliged? A guarantee given out of pressure rather than genuine willingness is the biggest red flag there is.

None of this is pleasant to raise. All of it is easier now than after settlement.

When not to do it

An honest guide has to include this section, so here is ours. A guarantor loan is the wrong tool when:

• The repayments are the real problem. A guarantee solves a deposit gap, not a servicing gap. If the buyer's income does not comfortably support the loan, adding the parents' home to the security pool makes the eventual failure bigger, not less likely.
• The parents need their equity soon. Close to retirement, planning to downsize, or carrying their own debt, the pledged equity may be needed for their own life. Their security comes first.
• Anyone is being pressured. If the enthusiasm flows only one way, stop.
• The relationship could not survive a bad outcome. Fragile family dynamics and contingent liabilities are a poor mix.
• A government scheme does the job without family risk. Between the federal scheme covered in our First Home Guarantee WA guide, the WA First Home Owner Grant, and the state's first home buyer duty concessions (our stamp duty WA guide covers the current thresholds), many WA buyers can get there without anyone guaranteeing anything. Exhaust those first.

Sometimes the right answer is a smaller purchase, a cash gift instead of a guarantee, or another year of saving. If that is the honest answer for your family, that is the answer we will give you.

Where this fits in the WA first home buyer picture

A family guarantee is one tool on a crowded bench alongside the federal First Home Guarantee, the WA First Home Owner Grant, stamp duty concessions and low deposit lending, and the right combination depends on the buyer, the property and the family behind them. We wrote a free guide, The WA First Home Buyer Stack, that walks through how the schemes fit together and the deposit maths most people never run. Request it below and we will email it to you personally, usually the same business day.

When you are ready to talk specifics, guarantor lending sits inside our residential finance work: two ex-bank credit people who have seen these structures from the lender's side of the desk, working alongside your family's own advisers. One conversation will tell you whether a guarantee is the right tool, what it should be limited to, and what the exit looks like.
