If you’re living overseas and wondering how much deposit you need for an expat mortgage, you’re not alone. This is one of the most asked questions by Australian expatriates.
Expat home loans don’t follow the same rules as standard Australian mortgages. Deposit requirements can vary significantly depending on where you live, how you earn your income, and which lender you apply with. Many Australians overseas are surprised to learn they can still buy or refinance property back home — but often with higher deposit requirements than onshore borrowers.
How Much Deposit Do I Need for an Expat Mortgage?
For most Australian expats, the minimum deposit required for an expat mortgage is 20% of the property value.
That means:
- Buying a $800,000 property typically requires a $160,000 deposit
- Buying a $1,000,000 property usually requires a $200,000 deposit
However, this is not a fixed rule. Some expats can buy with as little as 10%, while others may need 25–30% or more, depending on their circumstances.
How Much Deposit Do Australian Expats Need Compared to Residents?
Australian lenders generally view expats as higher risk borrowers, even if they are Australian citizens.
Key differences include:
- Income earned overseas is harder to verify
- Foreign currency income is often “shaded”
- Lenders factor in currency volatility
- Fewer banks actively lend to expats
As a result, deposit requirements for expat home loans are usually higher than for residents, where 5–10% deposits may be common.
Can I Get an Expat Mortgage with a 10% Deposit?
When Is a 10% Deposit Possible for an Expat Mortgage?
Yes — a 10% deposit is possible, but only in limited situations.
Some lenders may allow this if:
- Lenders Mortgage Insurance (LMI) is available and approved
- You have strong PAYG income from an accepted overseas country
- You have a long, stable employment history
- You can demonstrate genuine savings
- You use equity in an existing Australian property
This option is more common with specialist lenders, not major banks, and approvals are assessed on a case-by-case basis.
Is Lenders Mortgage Insurance (LMI) Available for Expats?
A small number of lenders do allow LMI for expat borrowers, which can make lower deposits feasible.
However, it’s important to understand:
- LMI premiums are often higher for expats
- The cost is usually added to the loan
- This increases your total repayments over time
LMI can help expats enter the market sooner, but it should be weighed carefully against long-term costs.

How Much Deposit Do Most Expats Need? (20%–30% Explained)
Why Is a 20% Deposit the Most Common Requirement?
For the majority of expat home loans, lenders cap borrowing at 80% Loan-to-Value Ratio (LVR).
That means:
- 80% LVR = 20% deposit
- No LMI required
- Broader lender choice
- More competitive interest rates
This is the sweet spot most lenders are comfortable with for Australian expats.
When Do Expats Need a 25–30% Deposit?
Some lenders require larger deposits in higher-risk scenarios, including:
- Self-employed expats
- Income from non-standard countries
- Income in volatile currencies
- Complex tax structures
- Foreign nationals or non-permanent residents
In these cases, lenders may limit borrowing to:
- 75% LVR (25% deposit)
- 70% LVR (30% deposit)
This reduced LVR helps lenders offset perceived risk.
Loan-to-Value Ratios (LVR) and Expat Mortgage Deposit Rules
How LVR Affects Your Expat Mortgage Deposit
| LVR | Deposit Required | Typical Scenario |
| 90% | 10% | Rare, LMI required |
| 80% | 20% | Most common for expats |
| 70–75% | 25–30% | Higher-risk profiles |
Many Australian lenders will only consider expat loans without LMI, which is why the 20% deposit threshold is so common.
Do PAYG Expats and Self-Employed Expats Need Different Deposits?
Deposit Rules for PAYG Expats
Expat borrowers with PAYG income may be able to:
- Borrow up to 90% of the property value
- Use LMI where available
- Access more lender options
This typically requires:
- Stable overseas employment
- Clear income documentation
- Income from accepted countries

Deposit Rules for Self-Employed Expats
Self-employed expats are assessed more conservatively.
Many lenders:
- Do not accept self-employed foreign income
- Require larger deposits
- Limit borrowing to 70–80% LVR
Each case is assessed individually, and deposit requirements vary significantly.
Do Expat Mortgage Deposits Need to Be Genuine Savings?
Yes. In most cases, expat mortgage deposits must be genuine savings.
This means:
- Savings held for at least 3–6 months
- Funds accumulated through income or surplus cash flow
- Clear transaction history
Acceptable alternatives may include:
- Equity from Australian property
- Sale of assets
- Inheritance or gifts (with evidence)
What Other Costs Do Expats Need to Budget For?
The deposit is only part of the upfront cost.
Expat buyers should also budget for:
- Stamp duty and government charges
- Legal and conveyancing fees
- Loan application and valuation fees
- FIRB approval fees (if applicable)
Government guidance on property costs is available via Moneysmart and the Australian Taxation Office.
Independent deposit benchmarks and lender commentary are also published by Wise.
Key Takeaways: Expat Mortgage Deposit Requirements
| Loan Type | Typical Deposit |
| Standard expat mortgage | ~20% |
| Specialist lender with LMI | ~10% (less common) |
| Higher-risk expat loans | 25–30%+ |
Using equity from existing Australian property can significantly reduce the cash deposit required, while foreign income shading may increase it.
