A property can look immaculate during a Saturday inspection and still carry problems that are costly, disruptive or difficult to remedy after settlement. That is why the question of when should buyers order inspections deserves an early answer, not one left until contracts are nearly exchanged. In NSW, the safest time is usually before you make an unconditional commitment to buy.
For most houses, that means arranging building and pest inspections as soon as the property has become a serious prospect. For apartments, townhouses and villas, it also means obtaining and carefully reviewing a strata inspection report before exchange. The right timing depends on how the property is being sold, but the principle is the same: understand the condition and likely risks before they become your responsibility.
When should buyers order inspections in NSW?
Buyers should generally order inspections before exchanging contracts, or before bidding at auction. This gives you the opportunity to consider the findings, seek further advice where needed, adjust your offer, or walk away if the risks are greater than you are prepared to accept.
Once contracts are exchanged in a private treaty sale, a buyer may have a cooling-off period, commonly five business days, unless it has been waived or varied. Inspections can sometimes be arranged during that period, but relying on it creates unnecessary pressure. A report may identify an issue that requires a specialist assessment, a repair quote or further legal consideration. Five business days can disappear very quickly, particularly where access needs to be organised.
At auction, the position is more serious. There is no cooling-off period for a successful bidder. If you bid and win, you are committed to the purchase. Building, pest and strata investigations should therefore be completed before auction day, alongside a thorough review of the contract for sale.
Why early inspections protect more than the purchase price
An inspection is not simply a box to tick for the bank or agent. It is part of your due diligence and can influence both your decision and the terms on which you buy.
A building report may reveal evidence of movement, moisture damage, drainage concerns, roof issues, unsafe structures or unapproved work. A pest inspection may identify active termites, past termite damage or conditions that make infestation more likely. These findings do not always mean a property should be avoided. Older Sydney homes, in particular, often have maintenance items and imperfections. What matters is understanding the scale, urgency and likely cost before you proceed.
For strata properties, the strata report can be just as significant as a building inspection. It may reveal planned special levies, building defects, insurance claims, disputes, poor financial management, water penetration, combustible cladding concerns or major works under discussion. A well-presented unit can still sit within a scheme facing substantial future expenditure.
Early information gives buyers choices. You may decide the property remains right for you at the agreed price. You may negotiate where appropriate, particularly before contracts are exchanged. Or you may decide to keep looking, with the confidence that you have avoided a commitment that did not suit your budget or risk appetite.
The right timing for private treaty purchases
In a private treaty sale, ask for a copy of the contract as soon as you are genuinely interested. Your conveyancer can review it while you organise inspections. These two steps work best together: the physical condition of the property and the legal terms of the purchase can each reveal risks that affect the other.
It is sensible to book inspections before making an offer where the market allows. In a competitive market, some buyers make an offer first and request a short period to complete due diligence before exchange. This can be workable, but only if you are clear that you are not yet exchanging contracts and the agent understands your position.
Avoid treating an accepted offer as a secured purchase. In NSW, a property is not sold to you merely because the vendor has accepted your offer verbally. Until contracts are exchanged, another buyer may make a stronger offer and the vendor may choose to proceed with them. That reality can make buyers feel rushed, but it should not lead you to waive sensible investigations without understanding the consequence.
If you exchange with a cooling-off period, arrange inspections immediately and confirm the deadline with your conveyancer. Do not assume that a report arriving on the final day leaves enough time to assess a serious issue properly. You may need a further inspection, advice from a builder or engineer, or a discussion about whether to rescind the contract within the required timeframe.
Auction buyers need reports before they bid
Auction conditions change the sequence, not the need for due diligence. Before bidding, obtain the contract, have it reviewed, order appropriate reports and make sure finance is in place. You should also inspect the property more than once where possible, including at a different time of day if traffic, noise, parking or nearby activity may affect your decision.
A pre-auction building and pest inspection is particularly valuable for freestanding homes, terraces and older properties. If the report identifies an issue, you can seek specialist advice before deciding on your maximum bid. The same applies to strata records for units and townhouses.
Some buyers hesitate because an auction report costs money with no guarantee of securing the property. That is a real trade-off. However, the cost of careful pre-purchase due diligence is usually modest compared with the financial exposure of buying a property with undisclosed defects or looming strata expenses. It can also prevent you from bidding beyond a figure that reflects the property’s true condition.
Which inspections are relevant to the property?
The inspection you need depends on the property type, age and location. A standard building and pest inspection is commonly appropriate for a house, but it may not identify every issue. Inspectors generally conduct a visual assessment of accessible areas, rather than dismantling walls, lifting flooring or testing every service.
Where the report raises concerns, a more targeted inspection may be worthwhile. For example, signs of cracking may warrant engineering advice. Evidence of water damage could justify a roof plumbing or waterproofing assessment. Properties with pools should be checked for compliance and safety issues, while acreage or semi-rural properties may need closer consideration of septic systems, water supply, access and boundary arrangements.
For a strata property, order a strata inspection report and read it alongside the contract. The report should provide insight into the owners corporation’s records, finances, meeting minutes, by-laws and known building issues. A building inspection may still be useful for the lot itself, especially where there are visible signs of moisture, renovations or defects, but it will not replace a review of the strata records.
Do not confuse an inspection with legal due diligence
A building inspector assesses physical condition. Your conveyancer or property lawyer assesses the legal documentation and transaction risks. Both are needed, and neither replaces the other.
A contract review can identify easements, restrictions, proposed road works, council notices, zoning information, inclusions, tenancy arrangements and special conditions that may affect how you use or finance the property. For strata purchases, legal review also helps you understand matters such as by-laws, parking or storage entitlements, and whether the contract correctly identifies what you are buying.
It is also worth remembering that inspection reports are not a warranty. Read the exclusions and recommendations. If a report says an area could not be accessed, or recommends further investigation, take that seriously before exchange. Asking questions early is far easier than trying to resolve a costly surprise after settlement.
A practical approach when time is tight
In a fast-moving Sydney market, buyers often feel they must choose between moving quickly and being careful. You can do both by preparing before the right property appears. Speak with a lender or broker about your borrowing position, engage your conveyancer early, and keep funds available for reports.
When you find a property you like, request the contract promptly and book inspections without delay. Let the inspection findings guide your decision rather than allowing auction pressure, fear of missing out or cosmetic presentation to do so. If the property has clear defects, decide whether you have the budget, appetite and time to manage them.
A careful purchase is not about finding a flawless property. It is about knowing what you are buying, what it may cost to maintain, and whether the legal and practical risks are acceptable to you. Ordering inspections early gives you the space to make that decision with clarity and far greater peace of mind.
