At MULLIGAN Buyers Agents, we’ve seen first-home buyers across Sydney get caught off guard by the hidden costs of buying property. Many plan for their deposit and loan, but forget about the additional expenses that can add tens of thousands to their purchase. With entry-level homes starting at $1.2M in many Sydney suburbs, overlooking these costs can derail your buying plans, especially since buyers often miss the hidden costs.
Stamp Duty in NSW
Stamp duty is one of the biggest upfront costs. For a $1.2M property, it can exceed $50,000 unless you qualify for first home buyer exemptions or concessions. These expenses shouldn’t be hidden to potential buyers.
Legal and Conveyancing Fees
Expect $2,000–$4,000 for legal professionals to review contracts, handle due diligence, and manage settlement, another potentially hidden cost for buyers.
Lender’s Mortgage Insurance (LMI)
Borrowing over 80%? LMI can add $20,000–$30,000+ to your costs on a $1.2M purchase, which is often a hidden cost buyers should be aware of.
Building and Pest Inspections
$600–$1,000 per inspection is common. A small price compared to the risk of missing major issues, yet still a hidden expense for buyers.
Moving Costs and Ongoing Expenses
Removalists, council rates, and strata fees all add up, but most buyers only realise too late that these are hidden costs they hadn’t anticipated.

Frequently Asked Questions About Sydney Hidden Costs
What is the hidden costs of buying a property in Sydney?
The hidden costs of buying a house in Sydney include stamp duty, legal fees, loan establishment fees, pest and building inspections, strata reports for apartments, and moving expenses. These can add tens of thousands of dollars to your purchase price.
How much should I budget for hidden costs when buying a property?
A safe rule of thumb is to budget between 5% and 7% of the property price for hidden costs. This covers government charges, professional fees, and upfront expenses, ensuring you’re not caught out when settlement arrives.
Are hidden costs the same for houses and apartments?
Not always. Houses may need more maintenance or land-related costs, while apartments often involve strata reports and ongoing levies. Each property type has unique hidden costs that buyers need to account for.
Why do buyers often overlook hidden costs when purchasing a home?
Many buyers focus only on their deposit and loan repayments. Without factoring in extra fees like stamp duty or inspections, budgets can quickly blow out. First-home buyers are especially vulnerable to this oversight.
How can a buyers agent help with hidden costs?’
A buyer’s agent helps identify and explain hidden costs upfront, from contract reviews to inspections and government charges. They also provide an independent estimate, so you know the true cost of buying before making an offer.
