5 Ways Parents Can Help You Buy a House (Compared Properly)

Two Families, Two Right Answers

One father summed up a decision we help families make every week. After weighing the guarantor paperwork, the liability and the multi-year commitment, he chose to simply give his daughter $50–60K toward her deposit instead — “call it early inheritance.”

Another family ran the same comparison and landed the opposite way: the guarantee cost nothing upfront and their equity did the work, no cash needed.

Both were right. The mistake isn’t picking the “wrong” structure — it’s not knowing there are five, each with different risk, cost, tax and lending consequences. Banks won’t lay them out side by side for you (most only sell one or two of them), so here’s the comparison we walk families through, with real numbers from real files. (Part of our complete guarantor guide.)

The Five Structures at a Glance

1. The Gift — Simple, Powerful, Underrated

A cash gift is the structure most families never properly price, and it’s often the winner. On one of our files, a $40,000 gift did one job brilliantly: it cut the LMI premium from $32,000 to $13,000 — the gift effectively paid for itself in insurance saved before it touched the purchase.

The mechanics matter: lenders want a signed gift letter confirming the money is non-repayable, and gifted funds usually need to sit in your account for around three months to count as genuine savings— or you need a lender that doesn’t require seasoning (what genuine savings means). For pension-age parents, Centrelink’s gifting rules can affect entitlements — worth a Services Australia check before large gifts.

Why parents choose it: it’s clean. No ongoing liability, no bank paperwork on their property, no exit strategy required. Why they don’t: it takes actual cash, and not every family has $40K liquid even when they’re equity-rich — which is exactly what the guarantee solves.

2. The Guarantor — Equity Does the Work

The guarantee may turn parents’ equity into additional security without a cash contribution: some lenders may fund the purchase price plus eligible costs, and a suitable structure may reduce or avoid LMI. Liability and release timing depend on the lender and guarantee contract. We’ve covered what it does and doesn’t do, who qualifies and the risks, written for your parents in detail.

The one-line decision rule from those guides: a guarantor solves a deposit problem, never a servicing problem — and if you qualify for the 5% Deposit Scheme under your price cap, run that comparison first, because it may deliver the same result with zero family risk.

3. The Co-Borrower — When the Problem Is Servicing

If your income can’t support the loan, pledged equity won’t help — but a parent joining the loan as co-borrower adds their income to the assessment. This is the structure that fixes servicing shortfalls, and it’s also the one with the most strings attached: the parent is fully liable for the whole loan (not a capped guarantee), the debt affects their own borrowing power and retirement planning, and lenders will want an exit strategy if the parent is near retirement — we’ve sat with families mapping exactly that: downsizing plans, super payouts, timed refinances to remove the parent later.

Ownership structure needs care too: a co-borrower usually goes on the title, which can trigger stamp duty on their share and affect your first-home concessions. Some lenders offer property-share loan structures that keep the borrowing and ownership cleanly split — which brings us to option four.

4. Property Share — Buying Together, Cleanly

Some families don’t want to help buy a home — they want to buy one together: a dual-living property, a house with a granny flat, an investment held across generations. A couple of lenders offer property-share structures that make this clean, and the structuring detail matters more than the product name. On one of our files the split worked like this: everyone on the title, but the loan solely in the kids’ names — the parents’ half came in as cash, the kids financed their half, and neither generation’s borrowing was tangled in the other’s.

Get this structure wrong and you get the opposite: parents on a loan they didn’t need to be on, borrowing power damaged on both sides, and messy exits. We’ve also advised families to keep parents off the title entirely where the goal was simplicity — contribution as a gift or loan instead. The right answer depends on what the family is actually trying to own, and it’s worth an hour of structuring before anyone signs a contract. If you’re weighing genuine co-ownership, our guide to buying a house with your parents goes deeper on the joint-purchase path.

5. Shared Equity and the Family Sale

The fifth structure is the family home itself: parents selling to their kids at a family price, gifting equity in a property, or staying on as part-owners while the next generation buys in. This is where lending, tax and duty interact most sharply — stamp duty is generally assessed on market value regardless of the family price, the “gift of equity” can serve as your deposit with the right lender, and scheme eligibility has extra rules when buying from family. We’ve covered the mechanics in detail in our guide to transferring property within families, including the traps we’ve hit in real family purchases — like lenders capping the loan at the contract price rather than the valuation.

One more variant from our files: the parent who sells an investment property to fund help for multiple children at once — one sale, several deposits, mapped per child so the help lands evenly. Structure, again, is everything.

How Families Actually Decide

Three questions sort almost every family into the right structure:

1. Is the problem deposit or servicing? Deposit → gift, guarantor or the 5% scheme. Servicing → co-borrower or property share. (The myth that confuses this.)
2. Cash-rich or equity-rich? Cash → gift (price the LMI saving; it’s often spectacular). Equity → guarantor.
3. Helping, or owning together? Helping → keep it simple, keep parents off the title. Owning → property share, structured deliberately.

Then stress-test the choice against the ugly scenarios — job loss, rate rises, a relationship ending, a parent needing aged care — because the structures behave very differently under stress. That’s the conversation to have before contracts, with independent legal and financial advice for the parents (non-negotiable for guarantees, wise for everything else).

This guide is general information, not credit, legal or tax advice — tax and duty outcomes in particular need advice on your circumstances. Lender policies differ and change without notice; as at July 2026.

Every option on this page works — for the right family, in the right situation, stress-tested honestly. Our job is the comparison: we’ll price the gift against the guarantee against the scheme for your actual numbers, show both generations what they’re signing up for, and structure whichever wins so it doesn’t blow up anyone’s borrowing power. The assessment is free, and your parents are welcome on the call — we find the whole thing goes better when everyone hears the same numbers.
