A guarantor home loan allows you to buy property with a family member (usually a parent) guaranteeing part or all of your loan. This enables you to borrow more, avoid LMI, and buy sooner. This guide explains how guarantor loans work, the benefits, and the risks.
What is a Guarantor Home Loan?
A family member (guarantor) uses their property equity to secure your home loan:
How it works:
- You want to buy a home but lack deposit
- Parent/family member offers to guarantee
- Guarantor uses equity in their home as additional security
- You can borrow more (up to 105%)
- Avoid paying LMI
- Guarantor released once you have 20% equity
Who can be a guarantor: ✅ Parents (most common) ✅ Siblings ✅ Spouse/partner (if not co-borrower) ✅ Sometimes extended family
Cannot be guarantor: Friends Business partners Third parties with financial interest
How Guarantor Loans Work
Types of Guarantees
1. Security Guarantee (Most Common)
Guarantor pledges property as security:
- Doesn't guarantee the debt
- Just provides extra security
- Lender has mortgage over guarantor's home
- Limited to specific amount (usually 20-30%)
Example:
- You borrow: $500,000
- Property value: $500,000 (100% LVR)
- Guarantor guarantees: $100,000 (20%)
- If default: Lender can claim $100k from guarantor's property
2. Full Guarantee
Guarantor guarantees entire loan:
- Liable for full amount
- Less common (higher risk)
- Lender can pursue entire debt
3. Limited Guarantee
Guarantor liable only for specific amount:
- Cap at agreed figure
- Common: 20-30% of loan
- Protects guarantor from full exposure
Loan Structure Example
Typical structure:
You want to buy:
- Property: $600,000
- Have saved: $30,000 (5%)
- Need to borrow: $570,000 (95%)
- LMI would be: $23,000+
Without guarantor:
- Need 20% deposit: $120,000
- Can't proceed
With guarantor:
- Parents' home: Worth $700,000, loan $200,000
- Parents' equity: $500,000
- Parents guarantee: $120,000 (20% of your purchase)
Split loans:
- Loan 1: $480,000 (80% of property)
- Secured by your property only
- No guarantor needed
- Loan 2: $120,000 (20% of property)
- Secured by your property + guarantor's property
- Guarantor provides security for this portion
Result: ✅ No LMI paid (saved $23,000+) ✅ You buy with only $30k deposit ✅ Guarantor liability limited to $120k ✅ Parents retain access to $380k equity
Benefits of Guarantor Loans
1. Buy Sooner (Less Deposit Needed)
Enter market years earlier:
Without guarantor:
- Save $120k deposit
- At $1,500/month savings
- Takes 80 months (6.7 years)
With guarantor:
- Need only $30k (5%)
- At $1,500/month savings
- Takes 20 months (1.7 years)
- Buy 5 years sooner!
Benefits of early entry:
- Property appreciates while you own it
- Build equity sooner
- Avoid rent increases
- Start wealth building earlier
2. Avoid LMI
Save thousands in insurance:
LMI costs:
- $500k loan, 95% LVR: ~$23,000
- $600k loan, 95% LVR: ~$28,000
- $700k loan, 90% LVR: ~$20,000
With guarantor:
- Effective 100% loan
- No LMI required
- Save $20-30k
Why no LMI:
- Lender has security from two properties
- Risk reduced (two properties vs one)
- Effective LVR under 80%
3. Borrow More
Increase borrowing capacity:
Example:
- Income: $80,000/year
- Can borrow: $480,000 (normal)
- With guarantor: Can borrow $600,000+
Why:
- Two incomes assessed (sometimes)
- Lower effective LVR = lower risk
- Better serviceability assessment
4. Better Interest Rates
Access standard rates despite high LVR:
Without guarantor:
- 95% LVR loan: 6.5% + LMI
With guarantor:
- Effective 100% loan: 6.0%
- No LMI premium
- Standard variable rates
5. Build Equity Faster
Start with more leverage:
Example 5 years:
- Property: $600,000 → $750,000
- Loan: $570,000 → $520,000
- Equity: $30,000 → $230,000
- Gained $200k equity
Then:
- Refinance to remove guarantor
- Release parents
- Own property independently
Risks for Guarantor
Critical to understand before guaranteeing:
1. Financial Liability
If borrower defaults:
- Lender can claim from guarantor's property
- May force sale of guarantor's home
- Debt recoverable from guarantor
- Can affect guarantor's retirement
Example worst case:
- You default owing $500k
- Your property sold: Recovers $450k
- Shortfall: $50k
- Lender claims from guarantor
- Guarantor must pay $50k
2. Reduced Borrowing Capacity
Guarantor's equity tied up:
- Can't access guaranteed portion
- Limits guarantor's borrowing
- May prevent downsizing
- Affects financial flexibility
Example:
- Guarantor's home: $700k value, $200k loan
- Usable equity normally: $360k (80% - loan)
- Guaranteed amount: $120k
- Available equity: $240k (reduced)
3. Relationship Risk
Family dynamics:
- Strain on relationship if issues
- Difficult conversations about finances
- Potential resentment
- Christmas dinner awkwardness
4. Long-Term Commitment
Not short-term:
- Average guarantee: 5-7 years
- Until you have 20% equity
- Market dependent
- Can't just "change mind"
5. Impact on Guarantor's Plans
May affect:
- Retirement plans
- Downsizing options
- Investment opportunities
- Lending capacity
- Estate planning
Risks for Borrower
1. Over-Borrowing
Easy to borrow too much:
- Can borrow more than you can afford
- Serviceability still applies
- Interest rate rises hurt more
- Repayment shock if rates increase
Example:
- Borrowed $600k with guarantor
- Could only afford $500k normally
- Extra $100k = $632/month extra
- If rates rise 2%: Pain doubles
2. Negative Equity Risk
If property market falls:
- Borrowed $600k (100%)
- Property falls to $540k (10% drop)
- Underwater: -$60k
- Can't refinance to release guarantor
- Guarantor stuck for years
3. Delayed Independence
Financially linked to parents:
- Can't release until 20% equity
- May take 5-10 years
- Affects relationship dynamics
- Delays financial independence
4. Pressure to Succeed
Emotional burden:
- Can't let parents down
- Stress if financial difficulty
- Fear of default consequences
- Mental health impact
