Deposit is the upfront cash payment you make when purchasing property or assets. It represents your initial equity stake and reduces the amount you need to borrow.
How Deposits Work
Basic formula:
- Purchase price: $700,000
- Deposit: $140,000 (20%)
- Loan amount: $560,000
- Your equity: $140,000 from day one
Paid at exchange of contracts:
- Initial deposit (usually 5-10% of price) paid when you sign
- Remainder paid at settlement (30-90 days later)
Example timeline:
- Week 1: Offer accepted on $750,000 property
- Week 2: Exchange contracts, pay $37,500 deposit (5%)
- Week 3-12: Loan approval, building inspection, conveyancing
- Week 12: Settlement day, pay remaining $112,500 (15%) + stamp duty + costs
- Total deposit: $150,000 (20%)

Genuine Savings Requirement
Lenders prefer deposits from "genuine savings"—money you've saved over time, not gifts or windfalls.
Genuine savings:
- Salary deposited to savings account over 3-6 months
- Term deposits held 3+ months
- Shares/managed funds held 3+ months
Not genuine savings:
- Gift from parents (recent deposit)
- Tax refund (lump sum)
- Inheritance (just received)
- Selling assets (unless held long-term)
Typical requirement:
- 5% genuine savings (minimum)
- Remaining deposit can be gifts/windfalls
Example: $700,000 property
- Total deposit needed: $140,000 (20%)
- Genuine savings: $35,000 (5% minimum)
- Gift from parents: $105,000
- Lender accepts (meets 5% genuine savings threshold)
Source of Deposit Funds
1. Personal Savings (Best)
Demonstrated by:
- Bank statements showing regular deposits
- Consistent savings pattern (6-12 months)
- Funds held in your name
Example:
- Save $2,500/month for 24 months
- Total saved: $60,000
- Lender sees: Disciplined saver, low risk
- Strong application
2. Gift from Family
Common for first home buyers:
- Parents/family provide $20K-$100K+
- Must be documented as gift, not loan
Required documentation:
- Statutory declaration stating it's a gift
- Bank statements showing funds transfer
- Letter from donor confirming no repayment expected
Example:
- Your savings: $40,000 (genuine savings)
- Parents' gift: $90,000
- Total deposit: $130,000 (20% of $650K property)
- Acceptable (meets genuine savings + gift is documented)
3. Equity from Existing Property
Using equity as deposit:
- Own property worth $600K, owe $300K
- Equity available: $180K (80% LVR - $300K owing)
- Use $120K equity as deposit for $600K new property
Process:
- Refinance existing property to access equity
- Transfer funds to new purchase
- Secure both properties as collateral
4. First Home Buyer Grant
Government grant:
- $10,000-$30,000 (varies by state)
- Paid at settlement
- Reduces loan amount
Example: QLD regional buyer
- Property: $580,000
- Your savings: $58,000 (10%)
- First Home Buyer Grant: $30,000
- Effective deposit: $88,000 (15.2%)
- Loan: $492,000 instead of $522,000
5. Guarantor (No Cash Deposit)
Family guarantor:
- Parents use their property as security
- You provide minimal/no cash deposit
- Avoids LMI
Example:
- Property: $650,000
- Your savings: $30,000 (4.6%)
- Parents guarantee: $100,000 of their home equity
- Total security: $750,000
- Lender sees: 115% security
- LMI: $0
6. Superannuation (Rare)
First Home Super Saver Scheme:
- Save extra into super (up to $15K/year, $50K total)
- Withdraw for first home deposit
- Tax advantages
Limitations:
- Must be first home buyer
- Complex process
- Most use other deposit sources
Deposit vs Other Upfront Costs
Deposit is just one cost—don't forget the others.
Example: $700,000 property purchase in NSW
| Cost | Amount | % of Price | |------|--------|------------| | Deposit (20%) | $140,000 | 20.0% | | Stamp duty | $26,490 | 3.8% | | Conveyancing | $1,800 | 0.3% | | Building inspection | $600 | 0.1% | | Loan application | $400 | 0.1% | | Total upfront | $169,290 | 24.2% |
Cash required beyond deposit:
- Stamp duty: $26,490
- Conveyancing/legal: $1,800
- Inspections: $600-$1,200
- Moving costs: $1,500-$3,000
- Total extra: $30,000-$32,000
Common mistake:
- Save 20% deposit ($140K)
- Forget other costs ($30K)
- Short $30K at settlement (can't proceed)
Solution:
- Save 20% deposit PLUS 4-5% for costs
- Total: 24-25% of purchase price in cash
How Deposit Size Affects Borrowing
Interest Rates by LVR
Rate tiers:
- 60-70% LVR: 5.79% p.a. (lowest)
- 71-80% LVR: 5.99% p.a.
- 81-90% LVR: 6.29% p.a.
- 91-95% LVR: 6.59% p.a.
Example: $600,000 loan
- At 5.79% (30% deposit): $3,510/month
- At 6.59% (5% deposit): $3,820/month
- Difference: $310/month ($111,600 over 30 years)
LMI Costs by LVR
| LVR | LMI Cost (on $650K property) | |-----|------------------------------| | 80% or less | $0 | | 85% | $8,500 | | 90% | $18,500 | | 95% | $28,500 |
Example impact:
- 20% deposit: No LMI
- 10% deposit: $18,500 LMI
- Extra cost: $18,500 upfront (or added to loan = $25,000 over life)

Deposit FAQs

Before you start saving:
