Buying a house in Sydney is a major financial step. With property prices rising across New South Wales, one of the biggest questions every buyer asks is:
How much deposit do I actually need to buy a house in Sydney
This guide explains exactly how much you need, what lenders look for, how to reduce your upfront costs, and the fastest ways to save your deposit. At RNPSydney, we aim to simplify your buying journey by giving you accurate, easy-to-understand information so you can purchase your dream home sooner.
The Standard Deposit Required in Sydney
To buy a property in Sydney, the typical deposit ranges between:
✔ 5% deposit (minimum allowed by some lenders)
However, Lenders Mortgage Insurance (LMI) will apply.
Suitable for first-home buyers with lower savings.
✔ 10% deposit (common choice in Sydney)
Still may require LMI, depending on the lender.
✔ 20% deposit (recommended)
This is the ideal deposit to avoid LMI and get better interest rates.
How Deposit Requirements Change by Property Value
Sydney’s median house price is high, so your deposit amount depends on where you are buying.
| Sydney Region | Average Price | 20% Deposit |
| Eastern Suburbs | $3M–$5M | $600k–$1M |
| North Shore | $2.2M–$3.4M | $440k–$680k |
| Inner West | $1.8M–$2.7M | $360k–$540k |
| Hills District | $1.3M–$2.1M | $260k–$420k |
| Western Sydney | $850k–$1.4M | $170k–$280k |
| South-West Sydney | $700k–$1M | $140k–$200k |
How Much Deposit First-Home Buyers Need in Sydney
If this is your first home, you may qualify for:
✔ First Home Guarantee (5% deposit, no LMI)
The government secures part of your loan.
✔ First Home Buyer Assistance Scheme
Stamp duty exemptions or discounts.
✔ First Home Owner Grant (for new homes)
A $10,000 grant for eligible new builds.
These schemes significantly reduce the upfront deposit needed.
Why 20% Deposit Is Still the Best Choice
Even though low-deposit options exist, a 20% deposit remains the best because:
- You avoid LMI (can save $20,000–$60,000+)
- You get cheaper interest rates
- Banks see you as a low-risk borrower
- You borrow less, reducing repayment stress
How to Save for a Deposit Faster
Here are practical ways Sydney buyers are reaching their deposit sooner:
✔ 1. High-interest savings or term deposits
Keeps your savings secure and growing.
✔ 2. Salary sacrifice through super (FHSS Scheme)
Allows tax-free deposit savings.
✔ 3. Reduce discretionary expenses
Avoid subscriptions, luxury shopping, and dining-out costs.
✔ 4. Create a 12-month savings plan
Set automatic weekly transfers.
✔ 5. Consider buying in emerging suburbs
Western and South-West Sydney offer more affordable entry prices.
