For a $600,000 house in Sydney, you need a minimum deposit of $30,000 — which is 5% — though most lenders and financial advisors recommend saving at least $120,000, or 20%, to avoid additional costs and access better loan terms. The exact amount depends on your lender, loan type, and whether you qualify for government assistance schemes.
How Much Deposit Do You Actually Need on a $600,000 Home?
For a $600,000 property, the deposit requirement sits between $30,000 and $120,000 depending on the path you take. A 5% deposit ($30,000) is the minimum most lenders will accept. A 10% deposit ($60,000) improves your borrowing position. A 20% deposit ($120,000) is the threshold that eliminates Lenders Mortgage Insurance and gives you access to the most competitive interest rates. The right target depends on your financial position, timeline, and eligibility for support schemes.
The 20% Benchmark and Why It Matters
Saving $120,000 — 20% of a $600,000 purchase — is the standard lenders use to classify a loan as low-risk. Below this threshold, lenders view the loan as higher risk and typically require you to pay Lenders Mortgage Insurance (LMI). LMI protects the lender, not you, and can add thousands of dollars to your upfront costs. Reaching 20% also unlocks lower interest rates and stronger negotiating power with lenders, which reduces your total repayment cost over the life of the loan.
Low-Deposit Options — Buying with Less Than 20%
Buying with a 5% or 10% deposit is possible and increasingly common in Sydney, particularly for first home buyers. With a 5% deposit ($30,000), you will almost certainly pay LMI unless you qualify for a government guarantee scheme. With a 10% deposit ($60,000), LMI costs reduce significantly. Some lenders accept deposits as low as 2–5% for borrowers with strong income and credit profiles, though these products carry stricter eligibility criteria. A mortgage broker can identify which lenders offer the most competitive terms at your deposit level.
Understanding the total upfront costs of purchasing a property in NSW gives you a clearer picture of how much you actually need to have ready on settlement day — beyond the deposit figure alone.
What Additional Costs Come on Top of Your Deposit?
Your deposit is not the only financial commitment at settlement. Sydney buyers routinely underestimate the additional upfront costs that sit alongside the deposit, which can add $20,000 to $40,000 or more to your total cash requirement depending on the purchase price and your circumstances.
Stamp Duty, LMI, and Other Upfront Expenses in NSW
In NSW, stamp duty on a $600,000 property is approximately $22,490 for non-first home buyers. First home buyers may qualify for a full exemption or concession depending on the property type and scheme eligibility. LMI on a $600,000 purchase with a 5% deposit can range from $15,000 to $25,000, though this is typically added to the loan rather than paid upfront. Additional costs include conveyancing fees ($1,500–$3,000), building and pest inspections ($500–$800), and loan application fees. Budget for a total cash requirement of $150,000 to $165,000 if you are purchasing without first home buyer concessions and with a 20% deposit.
First Home Buyer Schemes That Reduce Your Deposit Requirement
Several government schemes available to first home buyers in NSW can significantly reduce the deposit you need to save. The First Home Guarantee (FHBG) allows eligible buyers to purchase with as little as a 5% deposit without paying LMI, because the federal government guarantees up to 15% of the loan. The NSW First Home Buyer Assistance Scheme provides stamp duty exemptions on properties up to $800,000, which directly reduces your total cash requirement at settlement. The Regional First Home Buyer Guarantee extends similar benefits to buyers purchasing outside major metropolitan areas. Eligibility for each scheme depends on income thresholds, property price caps, and whether you have previously owned property in Australia. Confirming your eligibility before you begin saving gives you a more accurate deposit target.
