A property due diligence checklist is the structured set of legal, physical, financial and environmental checks a buyer completes before a contract becomes unconditional. The core categories are title and ownership, contract and conveyancing terms, building and pest inspections, strata records where relevant, environmental hazards, boundary surveys and financial exposure. Some of these are DIY checks anyone can run in an afternoon; others, like a structural assessment or a title search interpretation, need a licensed professional.
TL;DR:
- Title searches must be current and include easements and covenants, as drainage easements or restrictions can significantly impact development plans.
- Contract reviews should verify that all conditions, including finance and inspections, are clearly written and aligned with current legal documents before signing.
- Building and pest inspections identify obvious issues but do not guarantee the absence of hidden problems; specialized testing may be necessary for older or problematic properties.
- Strata records reveal financial risks like underfunded maintenance funds or ongoing disputes, which could affect insurance, resale value, or future levies.
- Confirm flood, bushfire, and land contamination risks through government maps and tests before making an offer, since these hazards influence insurance costs and planning permissions.

What is a property due diligence checklist? The at-a-glance version
A due diligence checklist is really a risk filter you apply before you’re legally locked in. Run through these categories during any inspection or contract review, and flag anything marked “professional” for immediate follow-up.
- Title and ownership — check for caveats, covenants, mortgages and easements on the title search. Professional: conveyancer, before signing.
- Contract terms — cooling-off period, special conditions, finance and inspection clauses. Professional: conveyancer/solicitor, before signing.
- Building and pest — structural cracking, moisture, termite activity, roof condition. Professional: licensed inspector, within days of an offer.
- Strata records — sinking fund balance, special levies, disputes in minutes. Professional: strata report provider, post-offer.
- Environmental hazards — flood overlay, bushfire zone, contamination history. DIY via government maps, then professional testing if flagged.
- Boundaries — fence lines, driveway encroachments, survey pegs. Professional: registered surveyor, if any doubt exists.
- Finance — outstanding rates, likely repair costs, settlement timing. DIY plus your conveyancer.
Each of these gets its own detailed walkthrough below, including what red flags actually look like on paper.
Legal and title checks: what your title search actually reveals
A title search shows who legally owns the property, who else has a registered interest in it, and whether anything restricts what you can do with it. Reading one properly means understanding three specific terms: a caveat (a third party’s claim that can block a sale from completing), a covenant (a restriction on land use, often written by a previous developer), and an easement (a legal right for someone else, such as a utility provider, to access or use part of your land).
These aren’t abstract legal footnotes. A drainage easement running through the middle of a backyard can kill a granny flat plan. A restrictive covenant limiting building height can sink a subdivision. Consumer Affairs Victoria’s due diligence checklist for home and residential buyers specifically flags land boundaries and title exceptions as items every buyer should verify before signing, alongside planning controls and hazard risks.
Before you commit, work through this:
- Order a current title search, not one from months ago; ownership and encumbrances change.
- Ask your conveyancer to explain every notation in plain language, not legal shorthand.
- If the title references an easement or covenant, get a plan showing exactly where it sits on the block.
- Order a survey if the title history or existing structures suggest boundaries have shifted.
- Confirm mortgageability with your lender if title exceptions are unusual.
If your conveyancer flags something they can’t resolve quickly, treat that as a reason to slow down, not push through.
What should your contract review cover before you sign?
The sale contract is where due diligence findings turn into leverage. Reviewing it properly before the cooling-off period expires (or before you waive it) protects you from clauses that look standard but aren’t.
- Check the cooling-off and condition clauses first. Confirm the cooling-off period length for your state, and whether finance and building/pest conditions are actually written into the contract, not just verbally promised by the agent.
- Order council, water and rates searches immediately. These reveal unpaid charges, planning notices, and outstanding infrastructure levies that transfer to you at settlement if unresolved.
- Scrutinise deposit and settlement mechanics. Some contracts include early-release deposit clauses or short settlement windows that create cash-flow pressure you haven’t budgeted for.
- Use inspection findings to negotiate, not just to worry. A confirmed defect can become a price credit, a pre-settlement repair obligation, or grounds to walk away entirely under a special condition.
Read every special condition twice. Vendors sometimes attach clauses that quietly shift a cost or risk back onto the buyer, and it’s far cheaper to catch that in week one than after settlement.
How reliable are building and pest inspections?
A standard building inspection is a visual assessment. It identifies visible defects (cracking, moisture staining, roof damage, subfloor issues) but won’t detect problems hidden behind walls, under slabs, or inside wiring. That distinction matters because a clean report doesn’t mean a clean property; it means nothing obvious was visible on the day.
Pest inspections in Australia focus heavily on termites, and for good reason given the climate across most of the eastern seaboard and southeast Queensland. A pest report should note any active infestation, historical damage, and conducive conditions like moisture under the house or timber stacked against stumps.
Beyond the standard reports, some properties warrant specialised testing:
- Sewer camera scope for older homes with cast-iron or ceramic pipes.
- Asbestos testing for anything built or renovated before the mid-1980s.
- Timber decay assessment where subfloor moisture has been flagged.
- Structural engineer review where cracking patterns suggest movement, not just settling.
The hardest skill here is telling cosmetic issues apart from capital-cost items. Hairline plaster cracks are usually cosmetic; diagonal cracking through brickwork near door frames often isn’t. Industry guidance on cosmetic versus structural issues notes that structural defects in foundations, roofing and electrical systems are effectively non-negotiable costs; you’re either paying for them now through a price reduction or later out of your own pocket.
Pro Tip: Photograph every defect with a fixed reference point in frame, like a tape measure or door frame, and date the shot. Distance photos showing drainage slope or foundation lean, taken this way, tend to carry far more weight in a re-trade negotiation than close-up shots alone.
What strata documents should you request for a unit or townhouse?
If you’re buying into a strata scheme, the building inspection tells you half the story. The owners corporation records tell you the rest, and they’re where the real financial risk usually hides.
Request the strata minutes (at least the last two to three years), the strata roll, the current insurance schedule, and the sinking fund forecast alongside recent budgets. Read the minutes for patterns, not just individual entries.
- Frequent special levies suggest the sinking fund isn’t keeping pace with maintenance needs.
- Ongoing disputes between owners or with the managing agent often signal deeper governance problems.
- An underfunded sinking fund against a known upcoming cost, like a lift replacement or facade repair, means a large levy is coming whether it’s disclosed yet or not.
These issues don’t just affect your bank balance. Lenders scrutinise strata financials during valuation, and an underfunded building can be harder to finance, harder to insure, and harder to resell at a fair price down the track.
How do you check flood, bushfire and contamination risk?
Environmental checks used to be an afterthought in Australian property buying. They shouldn’t be. Geoscience Australia’s flood study web lets buyers check flood-prone mapping for a specific address, and local council overlay maps do the same for bushfire risk. Both are free, both take minutes, and both should happen before you fall in love with a property, not after.
For contamination and industrial impacts, EPA Victoria maintains guidance on commercial and industrial noise that buyers near industrial zones should review, alongside separate registers covering land contamination history.
- Check government flood and bushfire overlay maps for the exact address, not just the suburb.
- Search EPA registers if the property sits near current or former industrial land.
- Commission a Phase I environmental assessment or soil test if historical land use (a former service station, tannery or factory site) raises red flags.
- Ask neighbours directly about odour or noise; it rarely shows up on paper but always shows up in daily life.
A flagged flood overlay doesn’t necessarily kill a purchase. Properties in Australia’s higher-risk flood zones can face materially higher insurance premiums, and some insurers apply exclusions or higher excesses; that’s a genuine cost to factor into your offer, not just a compliance box to tick.
Land boundaries and encroachments: when do you need a survey?
Order a current survey whenever fence lines, driveways or outbuildings look inconsistent with the title plan, or when a property has been extended or subdivided without clear documentation. Ask the surveyor to confirm boundary pegs on-site and mark any structure that crosses the line.
- Fences built a metre off the true boundary are common and usually resolved by agreement between neighbours.
- Driveways or garages encroaching onto a neighbouring lot are harder, sometimes requiring a formal easement or a boundary adjustment.
- Unresolved disputes can delay finance approval and knock resale value, since the next buyer inherits the same problem.
Sort boundary questions before settlement. Afterwards, you own the dispute along with the property.
What financial checks reveal the true cost of ownership?
Purchase price is only the headline number. Outstanding council rates, water charges, and any unpaid infrastructure levies should show up on recent notices; ask the vendor’s conveyancer for copies rather than taking a verbal assurance.
- Request the last two rates notices and current water account to spot arrears or looming charges.
- Add up near-term capital works flagged by your building inspection (a roof replacement, rewiring, restumping) and treat that as real, near-term spend.
- Ask your insurer for an indicative quote before you’re locked in; flood overlays, bushfire zones and older wiring can all push premiums up or trigger exclusions.
- Check the settlement date against your own cash position; a short settlement can force insurance, removalist and loan costs to land in the same week.
Budgeting for the property you’re actually buying, not the property in the listing photos, is what separates a smooth settlement from a stressful one.
What’s the right order and timeline for due diligence tasks?
Due diligence works best as a sequence, not a scramble. Some tasks belong before you even make an offer; others only make sense once you’re under contract.
- Pre-offer: Check government flood, bushfire and planning overlay maps, review recent sold prices, and skim strata minutes if available.
- Post-offer, subject to contract: Engage a conveyancer, order title and council searches, book building and pest inspections.
- Post-contract, pre-unconditional: Chase specialist reports (survey, structural engineer, environmental testing) triggered by earlier findings, and confirm finance approval.
A realistic residential timeline runs 7 to 14 days for standard checks, extending to 21 days where a specialist report or council search takes longer to return. Commercial due diligence often needs 30 to 60 days given more complex leases, environmental history and planning approvals. Engage your conveyancer first; they typically coordinate the sequence for building inspectors, surveyors and any environmental consultant that later findings require. Our guide to the Brisbane home buying process walks through how these steps fit together for a typical residential purchase.
Legal disputes and litigation history checks
A property can carry legal baggage that never shows up in a building inspection. Boundary disputes, unresolved building defect claims against a builder, tenancy disputes, or even litigation between neighbours over noise or access can all attach to a property or its owners corporation, and some of that history follows the asset rather than the seller.
Your conveyancer should search for registered caveats, court judgments affecting the title, and any notices of dispute lodged with the local council. For strata properties, the minutes are again the primary source; a scan for words like “dispute,” “tribunal,” “VCAT” or “legal action” across a few years of records tells you quickly whether the building has ongoing conflict. For commercial property, check whether any existing lease is subject to a rent review dispute or a make-good claim, since either can create a liability that transfers with the title.
If a dispute is found, don’t assume it’s automatically fatal to the purchase. Ask specifically: is it resolved, ongoing, or dormant? A resolved dispute from three years ago carries far less risk than an active tribunal matter. Where litigation touches the title itself, such as an unresolved boundary claim, treat it the same way you’d treat an unresolved caveat: get legal advice before you go unconditional, not after. Our article on legal considerations in property buying covers how these issues typically surface during a standard conveyancing process.
Review of utility services and infrastructure connections
Utility connections seem mundane until they turn into an expensive surprise. Confirm what’s actually connected, not just what’s advertised: mains water and sewer, or a septic system and rainwater tank; reticulated gas or bottled LPG; and, for regional or peri-urban properties, whether the electricity supply is single-phase or three-phase, which matters if you’re running workshop equipment or a larger air-conditioning system.
For newer estates or subdivided blocks, check whether infrastructure contributions have been paid in full. Growth-area developments in Victoria often carry staged infrastructure levies tied to roads, drainage and community facilities, and Victorian Planning’s guidance on growth-area contributions explains how these charges are calculated and when they fall due. An unpaid contribution can sit against the title and become the new owner’s problem if it isn’t cleared before settlement.
For commercial and industrial property, utility due diligence goes further again. Confirm the site has adequate power capacity for its intended use, ask for records of any recent NBN or fibre upgrades, and check whether stormwater and trade waste connections meet current council requirements. A change of use, from retail to a food business, for instance, can trigger a requirement for grease trap infrastructure that doesn’t currently exist. None of this shows up in a standard building report, so it has to be asked for directly.
Verification of easements and rights of way details
An easement grants someone else a legal right over part of your land, most commonly for drainage, sewerage, or shared access. A right of way is a specific type of easement giving another party, often a neighbour, the right to cross your land to reach their own property or the street.
The title search will list registered easements, but it won’t always make clear exactly where they sit or how they affect what you can build. Ask your conveyancer for a plan showing the easement’s precise location, then walk the site and check it against visible infrastructure like stormwater pits, manhole covers or a shared driveway. Consumer Affairs Victoria’s due diligence checklist specifically recommends buyers confirm land boundaries and easement positions before committing, precisely because these details are easy to overlook on a walk-through inspection.
Rights of way create particular friction in older suburbs with rear-lane access or shared driveways between two or three properties. Check who’s legally responsible for maintaining a shared right of way, since that obligation sometimes sits with all users jointly and sometimes with a single title. If an easement runs through a buildable area of the block, get written confirmation from council about what setbacks or restrictions apply before you factor in any extension or granny flat plans. Discovering a sewer easement running through your intended alfresco extension after settlement is a genuinely avoidable mistake.
Assessment of property tax obligations and benefits
Every property carries ongoing tax and rate obligations that vary by state, council area and how you intend to use the property. Council rates are charged by your local government and fund services like waste collection and local infrastructure; ask for the current rates notice to see the actual annual figure for that specific property, since it varies significantly by land value and council.
Land tax is a separate consideration for investment properties in most Australian states, generally applying above a state-specific land value threshold and calculated differently depending on whether the property is held individually, in a trust, or through a company structure. If you’re buying through a self-managed super fund, additional compliance obligations apply around how the property is held and used, and that structure needs to be confirmed with your accountant before contract, not after settlement.
There are also potential benefits worth checking. First-home buyers may be eligible for stamp duty concessions or grants depending on the state and the property’s value, while some states offer land tax exemptions for a principal place of residence. Depreciation benefits are relevant for investment purchases, particularly for newer or substantially renovated properties, where a quantity surveyor’s depreciation schedule can materially improve after-tax cash flow. None of these figures are universal; they depend on your state, your entity structure and the specific property, so confirm the applicable rates and thresholds with your accountant or conveyancer rather than relying on a general rule of thumb from a different state. For deeper detail on how tax exposure interacts with an investment purchase, see our guide on minimising risks in property investment.
How a buyer’s agent actually runs due diligence
Coordinating a full due diligence process solo means managing five or six professionals across overlapping deadlines, usually while still working full time. A buyer’s agent’s real value isn’t just booking the inspections; it’s converting what those reports uncover into quantified negotiation leverage, whether that’s a price credit, a re-trade, or a decision to walk away before you’re financially exposed.
Some buyer agents combine market data analysis with local inspection coordination across key Australian cities. A detailed building inspection can uncover underlying issues such as plumbing leaks that enable buyers to negotiate price reductions prior to finalizing the purchase.

How Invision Property handles due diligence for you
Running this checklist properly, alongside searching for the right property, negotiating price and staying across a moving settlement timeline, is a lot for one person to carry solo, especially if you’re buying interstate or from overseas. A buyer’s agent service can manage property search, inspections coordination, and negotiation on behalf of clients, often charging a transparent fixed fee instead of a percentage commission. Such fee structures align the agent’s incentive with negotiating a better price for the buyer.
Our team acts for buyers across multiple Australian markets and can operate nationally when data suggests an opportunity not yet widely noticed. That includes first-time and established investors, SMSF buyers, and interstate or overseas purchasers who need trusted eyes on the ground here. If you’re building a portfolio, our investment property buyers agent service folds this entire due diligence process into the purchase from day one; if you’re purchasing a home to live in, our home buyers agent Brisbane service does the same. Many buyers agents start the engagement with a preliminary strategy session to outline their approach before formal commitment.

FAQ
What should be included in a due diligence checklist?
A complete checklist covers title and ownership, contract terms, building and pest condition, strata records where relevant, environmental hazards, boundary accuracy, and financial exposure like outstanding rates. Each category needs both a DIY check, such as reviewing council maps, and a professional check, such as a licensed building inspection.
What is a due diligence checklist in real estate?
It’s the structured process of verifying a property’s legal status, physical condition, and financial obligations before a contract becomes binding. In Australia, Consumer Affairs Victoria’s checklist is a widely used reference covering planning, hazard and boundary checks specifically.
How much does a due diligence report typically cost?
Costs vary by report type and property, and current pricing isn’t published in a single standard rate across Australia, so it’s worth requesting quotes directly from your conveyancer and inspector. A buyer’s agent engagement that includes coordinating these reports, like the services listed on the Invision Property site, is charged as a fixed fee rather than a percentage of purchase price.
What should I check on my home inspection checklist in Australia?
Focus on visible structural signs (cracking, roof condition, moisture staining), pest and termite activity, and any subfloor or drainage issues, since a standard building report only covers what’s visible on the day. For anything ambiguous, such as a suspected structural crack, escalate to a specialist like a structural engineer before you go unconditional.
Do I need a survey for every property purchase?
Not always, but order one whenever fence lines, driveways or existing structures look inconsistent with the title plan, or when boundaries haven’t been formally confirmed in years. A survey resolves encroachment questions before settlement, when they’re far cheaper and simpler to fix.
