Home Loans for Grandparents Helping Family in Logan, QLD, The Guarantor Guide
Your grandchildren are ready to buy, but the deposit is the problem. It's one of the most common situations we see in Logan, QLD right now, and for grandparents who have owned their home for years and built up real equity, there's a way to help that doesn't mean handing over cash or going on the title.
A limited guarantor mortgage lets you use a portion of your home's equity to bridge your family member's deposit gap, without selling anything or touching your own savings. The lender takes a capped second mortgage over your property, the buyer gets into the market sooner, and once their equity reaches the required level, your property is released. Whether your grandchild is buying their first home near Woodridge or stretching toward something in Springwood, the structure is the same.
Our team helps families across Logan, QLD work through these arrangements carefully, comparing the conditions across 60+ lenders. The home loan structure you choose matters as much as the rate, and a guarantor arrangement is one where the details really do change the outcome.
Key takeaways
- The guarantee is capped, usually covering only the deposit gap, not the whole loan.
- No money changes hands at settlement between guarantor and buyer.
- Your property is released once the buyer's loan-to-value ratio falls below 80%.
Can grandparents act as guarantors on a home loan in Logan, QLD?
Yes, grandparents can act as guarantors in Australia, though lender eligibility varies more than it does for parents. Most lenders accept immediate family members, and many extend that to grandparents, but the approval depends heavily on your age at the point the loan matures, your own equity position, and whether your property is in a location and condition the lender will accept as security. A broker's job is to find the lenders on the panel whose policies actually fit your situation.
How does a guarantor home loan actually work for a grandparent?
The lender takes two separate securities: the property being bought and a limited mortgage over your property. That limited mortgage covers only the gap between the buyer's deposit and a 20% deposit, not the whole loan amount. So if your grandchild has a 5% deposit on an $800,000 purchase, the guarantee typically covers around 15%, and your property secures that portion only.
No money changes hands. You're not lending them cash, co-signing for the full debt, or appearing on the title. You're providing security, and that security is released once the buyer's equity reaches the required level, typically within three to seven years. The buyer services the loan entirely from their own income.
The guarantee is almost always capped at the gap between the buyer's deposit and 20% of the purchase price. Most lenders won't let a single guarantee exceed 50% of the guarantor's property value, so you need enough equity in your home to cover the gap while your own property stays comfortably below 80% LVR after the guarantee is added.
What surprises grandparents most is that they don't lose access to their own home or their savings. The guarantee is a legal commitment over a capped portion of equity, not a transfer of assets, and that distinction matters enormously when families are weighing it up.

What do lenders check before accepting a grandparent guarantor?
Lenders assess the guarantee the same way they assess any lending decision: they want to know the security is solid and the risk is manageable. For grandparents specifically, the assessment covers several things that don't arise when a parent guarantees.
What lenders check on a grandparent guarantee:
- › Age at loan maturity: most lenders assess the guarantor's age when the loan term ends, not at application. The common ceiling is 65 to 70 years at maturity, which means a 72-year-old guaranteeing a 30-year loan will face a narrower panel than a 60-year-old.
- › Property equity: the guarantee can't exceed 50% of your property's value at most lenders, and your own LVR must stay comfortably below 80% after the guarantee is secured against it.
- › Property location and condition: the guarantor's property must be in a location the lender accepts as security. Most Logan suburbs qualify, though rural or outer acreage properties can narrow the panel.
- › Independent legal advice: this is mandatory under most lender policies, not optional. The lender needs confirmation that you've received independent legal advice before the guarantee is executed.
- › Income is not assessed: as the guarantor, you're not servicing the loan. Your income is generally not part of the assessment unless the lender also wants you as a co-borrower, which is a different structure entirely.

How much can a grandchild borrow in Logan, QLD with a guarantor behind them?
The guarantor structure doesn't increase how much the buyer can borrow. What it does is remove the LMI cost that would otherwise apply when borrowing above 80% LVR, and it lets the buyer enter the market with a smaller deposit than they'd need on their own. CoreLogic data shows Logan house medians ranging from around $720,000 in Logan Central to $835,000 in Loganholme, and units sitting below both in most suburbs.
On an $800,000 purchase, a buyer with a 5% deposit would ordinarily face LMI of approximately $27,000 added to their loan. With a guarantor covering the 15% gap, LMI is avoided entirely. The buyer still needs to demonstrate they can service the loan from their own income, at an assessment rate of approximately 9% under the APRA buffer requirement.
Several Logan suburbs sit below the $1,000,000 First Home Guarantee price cap, so a first-home buyer might be able to combine the guarantor structure with the 5% Deposit Scheme for a 5% deposit with no LMI and no guarantee required. It's worth a conversation about which path suits the buyer's actual situation.

What government schemes can grandchildren use alongside a guarantor?
The guarantor structure and government schemes can work together, but they occupy different roles. The schemes reduce the deposit required or waive LMI; the guarantee provides the security the lender needs for a low-deposit loan. Not all combinations are available at every lender, so the path depends on which schemes the buyer actually qualifies for.
Schemes worth checking for the buyer:
- › First Home Guarantee (5% Deposit Scheme): a 5% deposit with no LMI and no income test. Logan's price cap is $1,000,000, covering most suburbs. A buyer using this scheme may not need a guarantor at all.
- › Queensland First Home Owner Grant:$30,000 on eligible new homes valued under $750,000. No income test. Can strengthen the buyer's deposit position before a guarantor is even needed.
- › QLD transfer duty concession:$0 duty on new homes (no price cap from 1 May 2025), and $0 on established homes up to $700,000. Citizenship and permanent residency required from 1 August 2026.
- › Help to Buy: federal shared equity, up to 40% for new homes. Income caps apply ($103,000 single, $165,000 joint from 1 July 2026). Cannot be combined with a state shared-equity scheme, but stamp duty concessions and the FHOG remain available alongside it.

When does a grandparent guarantee not make sense?
A guarantee is not always the right answer, even when the equity is there and the intent is generous. If your own retirement plans depend on selling or accessing your property equity in the next five to seven years, securing a second mortgage against it introduces a constraint you may not want. The guarantee can't typically be released until the buyer's LVR drops below 80%, and that timeline isn't always predictable.
It also makes less sense where the buyer's income genuinely can't service the loan. The guarantee resolves the deposit problem, not the serviceability problem. A buyer whose income, after the APRA assessment buffer is applied, won't support the repayments won't be approved regardless of who is guaranteeing. Getting clarity on this early saves everyone a difficult conversation later.
If you're over 75 at the time of application, the panel of willing lenders narrows considerably. That doesn't mean it's impossible, but it does mean the structure needs to be right from the start rather than being worked out after a decline sits on the buyer's credit file.
Where I'd lean: if the buyer has a real income and a genuine deposit shortfall, the guarantor structure is usually cleaner than waiting years to save the gap. But if the grandparent is within a few years of needing that equity themselves, I'd rather find a path that doesn't put their plans at risk. That conversation is worth having before anyone signs anything.

How do mortgage brokers help grandparents set up a guarantee in Logan, QLD?
The lender choice decides the outcome here, not the rate. Three policy differences move the result for grandparent guarantors specifically, and they're not published side by side anywhere.
- › Age ceiling at maturity: some lenders set the cutoff at 65, others at 70. For a grandparent in their late sixties, this single policy difference determines whether they're on the panel at all.
- › Eligible family members: some lenders restrict guarantors to parents; others extend the policy to grandparents. Applying to the wrong one and getting declined puts a credit enquiry on the buyer's file before the right conversation has happened.
- › Guarantee cap and release conditions: the mechanics of how much is guaranteed and what triggers the release differ between lenders. A lower cap and an earlier release threshold protect the grandparent better; knowing which lenders offer that is where comparing across a panel pays off.
Comparing across 60+ lenders finds the combination of terms that works for both sides of the arrangement, not just the buyer.
What approval challenges do grandparents acting as guarantors face?
Hurdles to know before you start:
- › Age at loan maturity: if the loan term runs to a point where the guarantor is past the lender's ceiling, the application won't proceed at that lender regardless of equity. The fix is a lender whose ceiling fits, not a shorter loan term forced on the buyer.
- › Existing mortgage on the guarantor's property: if you still carry a mortgage yourself, the available equity is net of that balance. Lenders calculate the gap between your current LVR and the 80% ceiling; the guarantee must fit within that room.
- › Independent legal advice delays: this step is mandatory and can add a week or two to the timeline if it's not arranged early. Families often underestimate how much time the legal advice requirement adds when settlement is already fixed.
- › Property type or location restrictions: some lenders won't accept rural, acreage or certain older property types as guarantor security. The outer Logan suburbs with larger blocks can occasionally trigger this, depending on the lender's assessment criteria.
Frequently Asked Questions
Can grandparents be guarantors if they still have a mortgage?
Yes, provided there's enough net equity. The lender calculates usable equity as the gap between your property value and 80% LVR after your own mortgage balance is deducted. The guarantee must fit within that remaining room.
Does a grandparent guarantor need to service the loan?
No. The buyer services the loan entirely from their own income. The grandparent's role is security only, so lenders generally don't assess the guarantor's income unless they're being added as a co-borrower.
How long does a grandparent's property stay secured?
Until the buyer's LVR falls below 80%, which typically takes three to seven years depending on repayments, property values and any lump-sum contributions. The release isn't automatic; it's triggered by an application to the lender.
Can a grandchild combine a guarantor with the First Home Owner Grant in Queensland?
Yes. The $30,000 FHOG for eligible new homes is paid to the buyer and doesn't affect the guarantee structure. The FHOG strengthens the buyer's deposit position, which may reduce the guarantee size required.
Is a grandparent guarantee the same as being a co-borrower?
No. A guarantor provides security but doesn't share the debt or appear on the title. A co-borrower is jointly responsible for the loan and is assessed on their income. They are different structures with different legal and financial consequences.
Should grandparents use a mortgage broker or go directly to a bank?
A mortgage broker, every time. Grandparent guarantor eligibility varies significantly between lenders on age ceilings, family-member definitions and guarantee caps. A broker identifies the lenders whose policies actually fit before any application is made.
Your Next Steps
Helping family buy sooner is one of the most meaningful things a grandparent can do with built-up equity, but the structure needs to protect both sides. The right arrangement keeps your retirement plans intact, gives the buyer a clean path to owning the property outright, and uses the lender's own policies rather than working around them.
