The Due Diligence Checklist Every Brisbane Property Buyer Needs in 2025
PA
PropertyLens AI## The Moment Before You Sign
Picture this: it's a Tuesday evening in late November, and a couple in Bulimba are sitting at their kitchen table staring at a contract of sale. They loved the house. Three bedrooms, a decent backyard, and close to the ferry. The agent has told them there's another offer coming. The pressure is real.
What they do in the next 48 hours will either protect them or haunt them for years.
Due diligence is not a bureaucratic formality. It is the difference between buying a solid asset and inheriting someone else's expensive problem. In Brisbane's market — where properties in inner suburbs regularly trade above $1.2 million and competition still compresses decision-making time — skipping steps is a risk that compounds quickly.
This checklist covers every major category. Some items cost money. All of them are worth it.
---
## 1. Title Search and Ownership Verification
A title search is the foundation of everything. It confirms who legally owns the property, whether there are any mortgages or charges registered against it, and whether any caveats exist that could complicate settlement.
In Queensland, title searches are conducted through the Titles Registry (managed by Titlesq). Your solicitor or conveyancer will run this as a matter of course, but you should understand what they're looking for:
- **Registered mortgages**: The seller's lender must discharge their mortgage before or at settlement. Confirm this is being arranged.
- **Caveats**: A caveat signals that a third party claims an interest in the property. Even a single unexplained caveat needs to be resolved before you proceed.
- **Easements**: More on these below, but the title search will reveal what's registered.
- **Covenants**: Restrictions that run with the land — sometimes limiting what you can build or how the property can be used.
Expect to pay $30–$80 for a standard title search. Your conveyancer will typically include this in their overall fee.
## 2. Flood Mapping and Overland Flow
This is Brisbane-specific and non-negotiable.
The 2011 floods inundated over 20,000 properties. The 2022 event hit suburbs that hadn't flooded in living memory — Rocklea, Oxley, Fairfield, and parts of Auchenflower and Chelmer. Flood risk in Brisbane is not just about proximity to the river. Overland flow — stormwater that has nowhere to drain — affects properties kilometres from any waterway.
**What to check:**
- **Brisbane City Council Flood Awareness Map**: This is the starting point. It shows flood categories (river flood, creek flood, overland flow) and the estimated depth under various scenarios. Access it free at the BCC website.
- **IDAS flood overlays**: Under the Brisbane City Plan 2014, properties in flood-affected areas carry planning overlays that restrict certain types of development and require specific building standards.
- **Flood history**: The map shows modelled risk, not necessarily actual flood history. Ask the agent directly — and in writing — whether the property has flooded. Sellers are required to disclose material facts.
- **Flood certificate**: You can request a formal flood certificate from BCC for around $120. This provides documented evidence of the property's flood category, which matters for insurance and future resale.
A property in Rocklea with a 1-in-20-year flood risk is a fundamentally different investment from a comparable house on the ridge in Tarragindi. The numbers might look similar. The risk profile is not.
## 3. Building and Pest Inspection
Never skip this. Even on a brand-new build.
A qualified building inspector will assess the structural integrity of the property — foundations, roof, walls, drainage, and any visible defects. A pest inspector looks specifically for termite activity, termite damage, and conditions that make infestation likely (moisture, timber-to-ground contact, poor ventilation under the floor).
In Brisbane, Queenslander-style homes with timber stumps and elevated floors are particularly vulnerable to termite damage. A house in Paddington or Ascot that looks immaculate from the street can have significant subfloor issues that only a qualified inspector will find.
**Practical notes:**
- Hire your own inspector, not one recommended by the agent. Independence matters.
- Combined building and pest inspections typically cost $500–$800 in Brisbane. For larger or older properties, budget higher.
- Always attend the inspection if possible. Inspectors will often explain issues verbally in more detail than they put in the written report.
- A report with issues is not necessarily a reason to walk away — it's a negotiating tool or a prompt to get specialist quotes.
Under Queensland contract law, most standard contracts include a building and pest condition that gives buyers the right to terminate or negotiate if the inspection reveals significant issues. Know your contract terms before you book the inspection.
## 4. Contract Review by a Solicitor
A contract of sale in Queensland is a legally binding document. The standard REIQ contract is relatively buyer-friendly, but variations, special conditions, and annexures can significantly alter your rights.
**What your solicitor should check:**
- **Settlement date**: Is it realistic given your finance timeline?
- **Inclusions and exclusions**: What fixtures and fittings are included? Disputes over dishwashers and light fittings are more common than you'd think.
- **Special conditions**: Sellers sometimes insert conditions that limit your ability to terminate or claim compensation. These need scrutiny.
- **Deposit terms**: Standard is 10%, but this is negotiable. Some sellers accept 5% with the balance on settlement.
- **Finance clause**: The standard REIQ contract includes a 14-day finance condition. Make sure this aligns with your lender's timeline — in late 2025, some lenders are still taking 18–21 days for formal approval.
- **Due diligence condition**: In a competitive market, some agents push buyers to go unconditional quickly. Resist this unless you have genuinely completed all checks.
A property solicitor in Brisbane typically charges $1,200–$2,000 for a standard residential conveyance. This is not where to cut costs.
## 5. Easements and Covenants
Easements give third parties the right to use part of your land for a specific purpose — most commonly, access to a neighbouring property, or the right of a utility company to run infrastructure across your block.
Covenants restrict what you can do with the land. Some are benign (minimum setbacks that match the surrounding streetscape). Others are genuinely limiting — prohibitions on subdivision, restrictions on building materials, or requirements that certain trees be maintained.
**Brisbane-specific considerations:**
- Many inner-Brisbane properties have **drainage easements** running along the rear or side boundary. These cannot be built over and limit landscaping options.
- Properties near legacy infrastructure — old tramway corridors, stormwater channels, electricity easements — often carry easements that significantly reduce the usable area of the block.
- **Covenant visibility**: Easements are registered on title and will appear in your title search. Some covenants, particularly older ones, may be registered separately. Your solicitor should check both.
Always ask for a survey plan and overlay the easements onto the block dimensions before making assumptions about what you can build.
## 6. Heritage Listings and Planning Overlays
Brisbane has a significant number of properties with heritage protection — both at the local government level (Brisbane City Plan) and state level (Queensland Heritage Register).
Heritage listing is not necessarily a dealbreaker. Many heritage-listed homes in Paddington, Toowong, and Hamilton are excellent properties. But heritage status imposes real constraints on what you can do with the property, and these constraints affect renovation costs, timelines, and development potential.
**What to check:**
- Search the **BCC Development.i portal** for planning overlays applicable to the property. This covers heritage, flood, character, and environmental overlays.
- Check the **Queensland Heritage Register** for state-level listings.
- If the property is in a **Character Residential** zone, there are specific rules about demolition, extensions, and alterations — even for non-listed properties.
- Heritage approval processes through BCC can add 3–6 months to renovation timelines and require specific materials and methods that increase costs by 15–30% compared to standard construction.
## 7. Infrastructure and Development Plans
What's being built near the property matters as much as the property itself.
Brisbane in late 2025 is mid-way through one of the largest infrastructure investment periods in the city's history. The Cross River Rail project, the Brisbane Metro, and the ongoing Olympic infrastructure program are all reshaping accessibility and amenity across the inner and middle ring.
**Research to do:**
- **Cross River Rail**: New stations at Boggo Road, Woolloongabba, Albert Street, Roma Street, and Exhibition are transforming catchment areas. Properties within 800m of these stations are seeing measurable price effects.
- **Brisbane Metro**: The expanded network through Toowong, Kelvin Grove, and the inner north is changing commute patterns.
- **Nearby development applications**: Search the BCC Development.i portal for any lodged or approved DAs near the property. A proposed 12-storey apartment tower next door is not something you want to discover after settlement.
- **Road and infrastructure projects**: TMR (Transport and Main Roads) publishes forward programs for major road works. A planned road widening can affect setbacks, noise, and even land resumption.
## 8. Body Corporate Records (Units and Townhouses)
If you're buying a unit or townhouse in Brisbane, the body corporate is a co-owner of your building. Its financial health is your financial health.
Under Queensland law, sellers of lots in a community titles scheme must provide a **body corporate disclosure statement** that includes recent financials, the sinking fund balance, and minutes of recent meetings.
**Key things to assess:**
- **Sinking fund balance**: This is the reserve for major capital works — roof replacement, lift maintenance, external painting. A sinking fund with less than 12 months of projected expenditure is a red flag.
- **Levies**: What are the current quarterly levies? Are increases planned? Some buildings in inner Brisbane have levies above $3,000 per quarter for high-amenity complexes.
- **Meeting minutes**: The last 2 years of AGM and EGM minutes will reveal disputes, planned major works, insurance claims, and any unresolved defects.
- **Insurance**: The body corporate insures the building structure. Check that the insured value is current and that there are no unresolved claims.
- **By-laws**: Do they allow pets? Short-term rentals (Airbnb)? Renovations? These matter enormously for how you can use the property.
For a deeper dive on body corporate assessment, the BCC strata report process and what to look for in sinking fund forecasts is covered separately in PropertyLens's guide to buying into a community titles scheme.
## 9. Neighbourhood Research
Data can tell you a lot. A Saturday morning visit can tell you the rest.
- **Walk the street at different times**: Morning, evening, and on a weekend. What's the noise level? Is there a pub nearby that gets loud on Friday nights? Is there a school drop-off that creates 20 minutes of chaos twice a day?
- **Talk to neighbours**: People who live nearby will tell you things that don't appear in any database.
- **Crime statistics**: Queensland Police publish suburb-level crime data. Check it.
- **Rental vacancy rates**: If you're buying an investment, the local vacancy rate tells you how competitive the rental market is. Inner Brisbane in late 2025 is sitting around 1.2–1.6% vacancy in most suburbs — tight, but worth confirming for your specific area.
- **School catchments**: Even if you don't have children, school catchment boundaries affect resale demand. Check the BCC school catchment tool.
- **Future land use**: Is the suburb zoned for increased density? Medium-density zoning can mean more neighbours over time, but it also underpins land value.

## One Final Thought
Due diligence costs money. A building and pest inspection, a solicitor's review, a flood certificate, and a title search might add up to $2,500–$3,500 before you've bought anything. On a $1.2 million property, that's 0.3% of the purchase price.
The alternative — discovering a termite-damaged subfloor, an unresolved caveat, or a drainage easement that prevents your planned extension — can cost tens of thousands. Or the deal itself.
The couple in Bulimba who were staring at that contract? They got the building inspection done. It revealed significant termite damage to three stumps and the rear deck. They went back to the seller, got a $28,000 price reduction, and had the work done properly after settlement. Due diligence paid for itself about 10 times over.
PropertyLens's research tools — including flood overlay mapping, suburb analytics, and AI-generated property reports — can help you build a picture of any Brisbane property before you commit to the paid inspection phase. It won't replace a solicitor or a building inspector, but it can tell you quickly whether a property is worth the deeper spend.
Picture this: it's a Tuesday evening in late November, and a couple in Bulimba are sitting at their kitchen table staring at a contract of sale. They loved the house. Three bedrooms, a decent backyard, and close to the ferry. The agent has told them there's another offer coming. The pressure is real.
