Hidden Costs of Buying a Home Australia

The deposit is the most visible cost of buying a home — but it is not the only upfront cost, and it is not even the most easily overlooked. Most buyers underestimate their total cash requirement by $10,000–$40,000. This guide covers every cost that catches buyers off guard.

What most buyers budget for vs what they forget

Here is how a typical first home buyer frames their budget — and what they leave out. The property in this example is $800,000.

Mortgage registration fee$150–$250
Lender establishment fee$0–$1,000
Moving costs$1,500–$5,000
Immediate repairs / updates$2,000–$20,000
Council rate adjustment$200–$800

⚠️ Why the range is so wide

The lower end applies to first home buyers in states with full stamp duty exemptions, with a 20%+ deposit (no LMI), buying a well-maintained property. The upper end applies to buyers in states with no first home buyer exemption, sub-20% deposit, and a property requiring moderate work. Your situation sits somewhere on this range — use the Total Upfront Cost calculator to find your specific figure.

Stamp duty — Australia's biggest hidden cost

Stamp duty (called land transfer duty in VIC) is a state government tax on property purchases. It is calculated as a percentage of the purchase price and varies significantly by state and buyer type.

Buyer typeVIC at $800k (approx.)NSW at $800k (approx.)
First home buyer~$22,000 (concession applies above threshold)~$31,090 (partial concession)
Non-first home buyer~$43,070 (full rate)~$31,090 (full rate)

These are indicative figures — use our Stamp Duty Calculator for your specific state, purchase price, and buyer type. Concession thresholds and exemption structures change periodically.

LMI — Lenders Mortgage Insurance

LMI applies when your deposit is less than 20% of the purchase price. It protects the lender — not you — in the event of default. Despite its name, you pay the premium.

On an $800,000 purchase with a 10% deposit ($80,000) and a loan of $720,000, LMI is typically $15,000–$20,000. Most lenders capitalise LMI onto the loan balance, meaning you pay interest on it for 25–30 years.

⚠️ LMI is not a one-off cost — it compounds

$18,000 of LMI added to a $720,000 loan at 5.85% over 30 years costs approximately $37,000 in total repayments over the life of the loan. Many first home buyers are unaware LMI exists until their loan approval documentation arrives.

Professional and transaction costs

CostTypical rangeNotes
Conveyancer / solicitor$1,200–$2,500Essential — handles contract review, title search, settlement
Building & pest inspection$400–$800Non-refundable — even if you don't proceed
Mortgage registration fee$150–$250State government fee to register mortgage on title
Lender establishment fee$0–$1,000Varies by lender — some waive this; others don't
Council rate adjustment$200–$800Pro-rata rate adjustment handled at settlement

Ongoing costs that appear immediately after settlement

These are not upfront costs in the traditional sense, but they arrive within the first quarter of ownership and are often not budgeted for alongside the purchase costs.

CostTypical amountFrequency
Council rates$300–$700Quarterly
Water rates$200–$400Quarterly
Buildings insurance$1,200–$2,500Annual (payable from exchange)
Moving costs$1,500–$5,000One-off

These add $3,000–$6,000/year in non-mortgage property costs on a typical capital city property. Budget for them from month one.

The "immediate repairs" reality

Even properties in "good condition" typically need attention on move-in. Budget $2,000–$5,000 minimum for:

  • Cleaning (professional clean if not included in contract)
  • Lock replacement (you do not know who has keys to the current locks)
  • Minor painting touch-ups
  • Garden attention
  • Minor repairs identified at inspection but not price-negotiated

For a property needing moderate cosmetic work — floors, kitchen refresh, paint — budget $10,000–$30,000 on top of this.
