The Due Diligence Checklist Every Brisbane Buyer Needs Before Signing Anything
PA
PropertyLens AI## The Contract Is on the Table. Don't Sign Yet.
It's a Tuesday evening and you've just walked through a Queenslander in Morningside that ticked every box. Three bedrooms, original timber floors, a deck that catches the afternoon breeze, and a price that — somehow — still feels achievable. The agent calls Wednesday morning. There's another offer coming. Can you sign today?
This is exactly the moment buyers make expensive mistakes.
Due diligence isn't just a phrase solicitors use to justify their fees. It's the structured process of finding out everything that could go wrong before you're legally committed to the purchase. In Brisbane, that process has some specific wrinkles — flood overlays, post-Olympic infrastructure corridors, ageing Queenslander frames, and body corporate levies that can quietly double your holding costs. Done properly, due diligence takes one to three weeks and can save you tens of thousands of dollars. Done poorly, or skipped entirely under pressure, it can saddle you with problems you'll spend years unwinding.
Here's the full checklist.
## 1. Title Search and Ownership Verification
The title search is the foundation of everything. It confirms who actually owns the property, whether there are any mortgages or caveats registered against it, and whether the land boundaries match what's being sold.
In Queensland, you can order a title search through the Titles Registry for around $17. Your conveyancer or solicitor will do this as a matter of course, but understand what you're looking for. **Caveats** indicate someone else has a claim on the property — a previous buyer, a business partner, a family member in a dispute. **Encumbrances** include mortgages that need to be discharged at settlement. Neither is necessarily a deal-breaker, but both need to be resolved before you can take clean title.
Also check that the property description in the contract matches the title exactly — lot and plan numbers, street address, and land area. Discrepancies, even small ones, can delay settlement.
## 2. Flood Mapping and Overland Flow
This is Brisbane-specific and non-negotiable. The 2011 floods inundated more than 28,000 properties. The 2022 event caught thousands more that had never flooded before. Flood risk in Brisbane is not theoretical.
Brisbane City Council's **Flood Awareness Map** is your starting point. Type in the address and you'll see whether the property sits in a flood awareness area, and if so, what category — riverine flood, creek flood, or overland flow. These are meaningfully different. Riverine flooding (from the Brisbane River or major creeks) tends to be deeper and more damaging. Overland flow — stormwater running across land during heavy rain — is more common and can affect properties nowhere near a waterway.
A few things to check beyond the council map:
- **Historical flood levels**: The council map shows modelled risk, not historical events. Ask the agent directly whether the property flooded in 2011 or 2022. Sellers have a disclosure obligation, but asking the question creates a paper trail.
- **Flood certificate**: Your solicitor should obtain a formal flood search from BCC, which provides the official flood flag for the property.
- **Insurance**: Before you exchange, call an insurer and get a quote. Some properties in flood-affected suburbs attract premiums that materially change the investment case. A $650,000 house in Rocklea with $6,000 annual flood insurance is a different proposition to one without it.
- **Building height**: For houses in flood-affected areas, check whether the building floor level is above the defined flood level. This affects insurability and future resale.
## 3. Heritage Listings and Planning Overlays
Brisbane has a substantial number of heritage-listed properties — individual homes, streetscapes, and character precincts — particularly in suburbs like Paddington, New Farm, Fortitude Valley, and Ascot. Heritage listing doesn't mean you can't renovate, but it does mean you need council approval for changes to the external fabric of the building, and that approval can be slow, conditional, or refused.
Check the **Brisbane City Council PD Online** planning portal. You're looking for:
- **Individual heritage listing** (most restrictive)
- **Character residential overlay** (applies to pre-1947 buildings across much of inner Brisbane — limits demolition and requires sympathetic renovation)
- **Neighbourhood plan overlays** (can affect what you can build, how high, and how many dwellings)
- **Demolition control precinct** (requires council approval to demolish)
If you're buying a Queenslander with plans to lift and build in underneath, or add a secondary dwelling, the character overlay and neighbourhood plan will dictate exactly what's possible. Understand these constraints before you factor renovation upside into your offer price.
## 4. Easements and Covenants
Easements are rights that allow someone else to use part of your land. Common examples in Brisbane include:
- **Drainage easements**: Council or a neighbour has the right to run stormwater infrastructure through your property. You can't build over them.
- **Electricity easements**: Energex infrastructure running underground or overhead. Building restrictions apply.
- **Access easements**: A neighbouring property has the right to cross your land to reach theirs.
Easements are shown on the title plan and the survey plan. Make sure you know where they sit on the block — an easement running through the middle of a 405m² lot in Bulimba can significantly limit what you can build.
**Covenants** are restrictions registered on the title that limit what you can do with the property. They're more common on newer estates and can include things like minimum build quality standards, approved materials, or restrictions on certain uses. Check the title carefully for any registered covenants.
## 5. Building and Pest Inspection
In Queensland, building and pest inspections are typically conducted during the due diligence period after you've exchanged contracts under a conditional clause. Budget $500–$800 for a combined inspection from a licensed inspector.
For Brisbane specifically, the things that come up most often:
- **Termite activity or damage**: Brisbane's subtropical climate is ideal for termites. This is not a minor issue. Active termites in a timber-framed Queenslander can mean $50,000–$150,000 in structural repairs. Always get a timber pest inspection, not just a building inspection.
- **Subfloor condition**: Older Queenslanders and post-war homes often have subfloor issues — rotting stumps, inadequate ventilation, moisture damage. Restumping a standard Queenslander costs $15,000–$35,000.
- **Roof condition**: Corrugated iron roofs on older homes may be at end of life. A full roof replacement on a typical Brisbane house runs $15,000–$30,000.
- **Asbestos**: Common in homes built between the 1940s and 1980s. Asbestos-containing materials don't necessarily need to be removed immediately, but they do need to be managed and disclosed.
- **Retaining walls**: Many Brisbane properties are on sloping blocks with retaining walls. These can be expensive to repair or replace — $1,000–$2,000 per linear metre for engineered walls.
Don't use the inspection report to renegotiate over minor defects. Use it to identify genuine structural issues that change the value of the property, and to understand what maintenance you're taking on.
## 6. Body Corporate Records (Units and Townhouses)
If you're buying a unit or townhouse in a community titles scheme, body corporate records are essential reading. Request the last two years of **AGM minutes**, the current **administrative and sinking fund levies**, the **sinking fund balance**, and any **special levies** that have been raised or are anticipated.
What you're looking for:
- **Sinking fund balance**: Is it adequately funded for the age and condition of the building? A 20-year-old complex with a $40,000 sinking fund and a roof that needs replacing is a problem.
- **Pending or recent special levies**: These are one-off charges to owners for major works not covered by the sinking fund. A $15,000 special levy for facade remediation can appear with very little notice.
- **Ongoing disputes**: Minutes will reveal if there are disputes between owners, issues with a particular lot, or ongoing legal matters.
- **Insurance**: The body corporate insures the building. Check the sum insured is adequate and that there are no gaps in coverage.
- **Levy amounts**: Body corporate levies in Brisbane vary enormously — from $3,000 per year for a small older complex to $15,000+ per year for a high-rise with a pool, gym, and concierge. Factor this into your holding cost calculations.
In Queensland, you're entitled to a **Body Corporate Information Certificate** (Form 14), which provides a formal snapshot of the scheme's financial position. Your solicitor should obtain this.
## 7. Infrastructure Plans and Development in the Area
Brisbane is in the middle of a significant infrastructure build-out ahead of the 2032 Olympics, and the decade following. Some of this infrastructure adds value — new train stations, upgraded roads, new parklands. Some of it doesn't — highway widening, flight path changes, industrial rezoning nearby.
Check:
- **Cross River Rail**: Stations at Boggo Road, Woolloongabba, Albert Street, Roma Street, and Exhibition are reshaping catchment values. Properties within 800m of these stations have seen measurable price premiums since construction confirmed.
- **Brisbane Metro**: The underground busway network connecting Eight Mile Plains to Roma Street affects inner-south and inner-west suburbs.
- **Olympic infrastructure**: The Athletes' Village at Northshore Hamilton, the Gabba redevelopment precinct, and the expanded Chandler sporting complex all have surrounding land use implications.
- **State Development Areas**: Check whether any nearby land is designated for industrial or commercial development that could affect residential amenity.
- **Road and tunnel projects**: The Kingsford Smith Drive upgrade and the proposed Suburban Roads Upgrade program affect traffic patterns and noise levels in various suburbs.
The **Queensland Government's ShapingSEQ** regional plan and BCC's **City Plan 2014** (currently under review) are the primary documents. Your solicitor can run planning searches, but it's worth doing your own research on the suburb's trajectory.
## 8. Contract Review
In Queensland, property is sold on the **REIQ Contract for Houses and Residential Land** or the **REIQ Contract for Residential Lots in a Community Titles Scheme**. These are standard forms, but the special conditions added by the selling agent can vary significantly.
Have a solicitor review the contract before you sign. Key things to check:
- **Settlement period**: Standard is 30–45 days. Shorter settlements can work in your favour in a competitive market but leave less time for finance.
- **Finance clause**: Ensure the finance amount, lender, and due date are correctly specified. An inadequate finance clause can leave you exposed.
- **Due diligence clause**: Make sure you have adequate time — typically 7–14 days — to complete inspections and searches.
- **Inclusions and exclusions**: What stays with the property? Dishwashers, light fittings, air conditioning units, and garden sheds are common sources of dispute if not clearly specified.
- **Existing tenancies**: If the property is tenanted, the lease terms transfer to you. Know the lease end date and current rent before you commit.
- **FIRB requirements**: If you're a foreign buyer or purchasing with a foreign national, Foreign Investment Review Board approval may be required.
## 9. Neighbourhood Research
This one doesn't come from a solicitor or an inspector. It comes from spending time in the suburb.
Visit at different times of day and on different days of the week. A street that feels quiet on a Saturday morning can be a different experience on a Friday night. Check proximity to flight paths (Brisbane Airport's flight paths affect suburbs including Hamilton, Ascot, Clayfield, and Hendra), train lines, and major roads.
Check recent sales data for comparable properties — not just the suburb median, but actual comparable sales within 500m in the last six months. Understand whether the asking price is justified by evidence or by optimism.
Look at what's been approved nearby on **PD Online**. A development application for a six-storey apartment building on the next block will affect your outlook and potentially your property value.
## Putting It Together
Due diligence in Brisbane isn't a single thing — it's a parallel process involving your solicitor, a building inspector, your mortgage broker, the council's online tools, and your own legwork. The checklist above covers the essentials, but every property has its own quirks.
For properties in flood-affected suburbs like Rocklea, Oxley, or Fairfield, flood risk analysis deserves extra time. For older Queenslanders in Paddington or Bardon, the character overlay and subfloor condition matter most. For units in New Farm or South Brisbane, body corporate finances and special levy risk are the priority.
The tools available to Brisbane buyers have improved considerably. PropertyLens's planning constraints layer pulls flood overlay data, heritage listings, and zoning information for any inner Brisbane property in one place — useful for a quick initial read before you commit to a full due diligence process. Their deep research reports also surface comparable sales and suburb trend data that can help you sense-check whether a price is realistic before you go too far down the path.
But no tool replaces a good solicitor, a thorough building inspector, and the discipline to slow down when an agent is telling you to hurry up. The best protection any buyer has is the willingness to walk away from a deal that doesn't stack up — and you can only do that if you've done the work to know what you're looking at.
It's a Tuesday evening and you've just walked through a Queenslander in Morningside that ticked every box. Three bedrooms, original timber floors, a deck that catches the afternoon breeze, and a price that — somehow — still feels achievable. The agent calls Wednesday morning. There's another offer coming.
