Family Guarantee is a specific type of loan where a family member (usually parents) uses their property equity as additional security to help you borrow more or avoid Lenders Mortgage Insurance. It's designed for first home buyers with insufficient deposit but strong repayment capacity.
How Family Guarantees Work
Your parents (or other eligible family members) pledge a portion of their property equity—typically 10-20% of your purchase price—as additional security for your loan.
Structure:
- You buy property: $700,000
- Your deposit: $70,000 (10%)
- Your loan: $630,000 (90% LVR normally requires LMI)
- Guarantor provides: $70,000-$140,000 security from their property
- Combined security: Your $700K property + guarantor's $70K-$140K = 110-120% total
- LMI: $0 (lender has sufficient security)
Key difference from standard guarantor:
- Limited guarantee: Only 10-20% of your property value (not unlimited)
- Specific product: "Family Guarantee Home Loan" offered by major banks
- Automatic release: Once you reach 80% LVR (typically 2-5 years)

Standard Guarantor Loan
Features:

How Much Can You Borrow?
Maximum LVR
With family guarantee:
- Typically up to 105% (includes small costs)
- Some lenders: 102-103%
Without family guarantee:
- Maximum 95% (with LMI)
- Often 90% practically
Example:
- Property: $720,000
- Deposit: $35,000 (4.9%)
- Stamp duty: $28,000
- Loan: $685,000 + $28,000 stamp duty = $713,000
- LVR: 99% (property $720K)
- With family guarantee: Approved
- Without: Declined (too high LVR)
Borrowing Capacity
Based on your income alone (guarantor's income not usually counted).
Example:
- Your income: $110,000
- Borrowing capacity: ~$550,000-$600,000
- With family guarantee: Can borrow up to capacity + avoid LMI
- Guarantee doesn't increase how much you can borrow (just avoids LMI)
Exception: Some lenders consider guarantor's income if they're co-borrowers (different structure).
Benefits of Family Guarantee
1. Avoid Lenders Mortgage Insurance
Save $10,000-$30,000 upfront.
Example:
- Property: $700,000
- Deposit: $70,000 (10%)
- Loan: $630,000 (90% LVR)
Without family guarantee:
- LMI: $22,000
- Total upfront: $92,000
With family guarantee:
- LMI: $0
- Total upfront: $70,000
- Savings: $22,000
2. Buy Sooner with Smaller Deposit
Enter market years earlier.
Example:
- Target property: $680,000
- Savings rate: $2,000/month
- 20% deposit needed: $136,000
- Time to save: 68 months (5.7 years)
With family guarantee:
- 5% deposit needed: $34,000
- Time to save: 17 months (1.4 years)
- Enter market 4.3 years earlier
Property appreciation during wait:
- 5% p.a. growth over 4.3 years = $160,000 increase
- Property now: $840,000 (unaffordable)
- Family guarantee enables purchase before price growth
3. Better Interest Rates
Higher LVR usually means higher rates—family guarantee avoids this.
Example:
- 95% LVR (with LMI): 6.5% p.a.
- 80% LVR equivalent (with guarantee): 6.0% p.a.
On $630,000 loan:
- @6.5%: $3,972/month
- @6.0%: $3,773/month
- Save: $199/month = $71,640 over 30 years
4. Lower Overall Costs
LMI + higher rates compound costs.
Example over 5 years:
Without family guarantee (90% LVR):
- LMI: $22,000 (added to loan)
- Loan: $652,000 @ 6.4%
- Total interest (5 years): $201,000
- Total cost: $223,000
With family guarantee:
- LMI: $0
- Loan: $630,000 @ 6.0%
- Total interest (5 years): $184,000
- Total cost: $184,000
- Savings: $39,000 over 5 years
Risks for Guarantors
1. Property at Risk
If you default, lender can claim guarantor's property.
Scenario:
- You lose job, default on loan
- Property sold: $690,000
- Your loan: $620,000
- Selling costs: $20,000
- Shortfall: $0 (no shortfall in this case)
But if property value fell:
- Property sold: $610,000
- Loan: $620,000
- Selling costs: $20,000
- Shortfall: $30,000
- Lender claims $30,000 from guarantor's property
Guarantor's maximum risk: Usually capped at guarantee amount ($130,000 in 20% guarantee scenario).
2. Reduced Equity Access
While guarantee is active, guarantor can't access guaranteed portion.
Example:
- Guarantor's property: $900,000
- Existing mortgage: $300,000
- Available equity (80% LVR): $720,000 - $300,000 = $420,000
- Guarantee provided: $140,000
- Remaining available equity: $280,000
Impact:
- Can't renovate using $140,000 of equity
- Can't invest using that equity
- Locked for 2-5 years until released
3. Credit Score Impact if You Default
Your default affects guarantor's credit file.
Scenario:
- You miss 3 repayments (default)
- Default listed on your credit file
- Also listed on guarantor's credit file
- Guarantor applies for loan: May be declined
Credit score impact:
- Guarantor's score drops 150-250 points
- Remains on file for 5 years
4. Relationship Strain
Family guarantees can create tension.
Common conflicts:
- Guarantor wants to downsize/sell (can't until guarantee released)
- You make financial decisions guarantor disapproves of
- You fall behind on repayments (guarantor stressed)
- Guarantor needs equity for emergency (can't access it)
Example:
- Parents guarantee your $650,000 loan
- Year 2: Parents want to retire, downsize, travel
- Can't sell home (guarantee still active)
- Need to wait until your LVR reaches 80%
- Resentment builds
Guarantee Release Process
When Is Guarantee Released?
Automatically when you reach 80% LVR.
Example:
- Original: $700,000 property, $630,000 loan (90% LVR)
- Guarantee: $140,000
3 years later:
- Property value: $800,000 (growth 4.5% p.a.)
- Loan paid down: $595,000
- LVR: 74.4% ($595K ÷ $800K)
- Guarantee released automatically
Guarantor's obligation ends.
How to Accelerate Release
1. Make extra repayments
- Pay extra $500/month
- Reach 80% LVR 2-3 years faster
Example:
- Minimum repayments: Reach 80% in 5 years
- Extra $800/month: Reach 80% in 3 years
- Guarantee released 2 years earlier
2. Property value increase + refinance
- Property appreciates 15%
- Request revaluation
- Refinance based on new value
- 80% of new value > current loan
- Guarantee released
Example:
- Original property: $700,000, loan $630,000 (90%)
- 2 years later: Property $805,000 (15% growth)
- Loan: $610,000 (paid down slightly)
- New LVR: 75.8%
- Request release (under 80% LVR)
3. Lump sum payment
- Inheritance, bonus, savings
- Pay down to below 80% LVR immediately
Example:
- Current LVR: 87%
- Receive $50,000 inheritance
- Pay down loan
- New LVR: 77%
- Guarantee released immediately
Release Costs
One-time fees:
- Discharge fee (remove guarantee from title): $300-$600
- Valuation (if required): $200-$600
- Total: $500-$1,200

- Combined guarantee: $192,000 (sufficient)
Structure:

- Father guarantees: $58,000 (only need $170K total)
- Both properties provide security
Release:
- Once borrower reaches 80% LVR
- Both guarantees released simultaneously
Example 3: Guarantee + Cashout (Higher Risk)
Borrower:

Family guarantee structure:
- Property: $680,000
- Stamp duty: $27,000
- Costs: $8,000
- Total needed: $715,000
- Deposit: $20,000
- Loan: $695,000 (102% of property value)
- Parents guarantee: $136,000 (20%)
Risk:
- Very high LVR (102%)
- If property drops 5%: $646,000
- Loan: $695,000
- Negative equity: -$49,000
- Parents' guarantee at risk
Outcome:
- Risky strategy
- Better to save more deposit first

Final Thoughts
Family Guarantee loans are powerful tools for first home buyers with strong income but insufficient deposit—they save $10,000-$30,000 in LMI and enable earlier market entry.
When family guarantees make sense:
- Stable, high income ($80K-$150K+)
- Small deposit (5-10%) but can afford repayments
- Parents have significant equity and are willing
- Planning to build equity quickly (extra repayments)
- Strong family relationships with open financial discussions
When to avoid:
- Income is unstable or marginal
- Family relationships are strained
- Parents need their equity soon (retirement, downsizing)
- Borrowing at absolute maximum (no buffer)
- Better to wait 12-18 months and save larger deposit
Key principles:
- Keep guarantee as small as possible (aim for 10-15%, not 20%)
- Make extra repayments to release guarantee ASAP (target 2-3 years)
- Have honest conversations with guarantors about risks
- Plan for release (track LVR quarterly)
- Consider government guarantee first (if eligible)
Typical success scenario:
- Property: $720,000, loan $648,000 with family guarantee
- Parents guarantee: $144,000 (20%)
- Make minimum + $1,000/month extra repayments
- Property grows 5%/year
- Year 3: LVR reaches 78%
- Guarantee released, saved $24,000 LMI, own home 4 years earlier
