Age & construction10 guides
Explore how your home was built and what its history can help explain.
How do I find out when my house was built?
How to work out when an Australian house was built, using council records, historical aerial photographs, the title, old listings and the clues in the building itself, and why the answer shapes what to check.
What are the common property red flags by era and construction type?
The build date is useful because it changes the questions, not because it predicts the answer. Read the original shell, later alterations, services and present condition together, then use the right evidence to test what is actually there.
What does a home need as it ages, decade by decade?
A home's age gives you a useful starting point, not a replacement schedule. Separate the original shell from later work, track each major system by its own date and condition, and turn uncertainty into a practical evidence and renewal plan.
What does a period home (pre-1920s) need?
What to check in a period home built before 1920: footings, damp, roofs, chimneys, services and alterations, and what should change your decision.
What does an interwar home (1920s–40s) need?
Interwar homes often combine durable original fabric with decades of repairs, extensions and service changes. Start underneath the house, follow water through the envelope, then separate original construction from later work.
What does a postwar home (1950s–70s) need?
What to check in a 1950s–70s postwar home: brick veneer or weatherboard, asbestos, wiring, wet areas and later renovations.
What does a 1980s–90s home need?

What does a modern home (2000s onward) need?
Newer does not mean evidence-free. For houses, read approvals, drainage, waterproofing, termite management, envelope detailing and workmanship. For apartments, add common-property defects, cladding, fire systems, insurance, governance and funding.
What should I check in a weatherboard home?
The paint is part of the weatherproofing, and the small junctions do the quiet work. Read the boards, flashings, openings, drainage and subfloor as one connected system.
What's the difference between brick veneer and double brick, and does it matter?
How brick veneer and double brick differ, the practical clues that tell them apart, and why it matters for cracks, damp, comfort and renovation.
Apartments & strata3 guides
Read both purchases: your lot, and your share of the common property, records and future costs.
What should I check before buying an apartment?
You are buying the apartment and joining the building around it. Read the lot, the common property and the scheme finances together before you commit.
How do I read owners-corporation or strata records?
The fund balance rarely tells the whole story. Read it beside the works plan, minutes, arrears, insurance and disputes to see what the building may ask of its owners next.
What are the main strata risks for apartment owners?
The strata risks that land on apartment buyers and owners: special levies, defects, cladding, insurance, and how to read the scheme records.
Maintaining & renovating6 guides
Keep useful records, maintain the fabric safely and plan works without over-promising what condition can prove.
What records should I keep for my home?
Your future self will thank you for a home record that is easy to search. Keep the plans, permits, invoices, warranties, photographs and reports that explain what changed and who did it.
What should be on a home maintenance checklist to prevent expensive repairs?
The maintenance that pays back usually keeps water moving away and catches small changes early. A simple home register helps you see what needs care now and what needs a future budget.
Does my home's condition affect my insurance?
Insurance responds to defined risks under a particular policy; building condition describes the asset the policy sits over. Understand both. Describe the home accurately, separate existing defects and maintenance from insured events, set a realistic rebuild basis and keep the evidence that explains what existed before a loss.
How do I prepare my home for storms, floods and bushfire?
A safer home starts with the people in it. Make the plan, know where warnings come from and plan to act early, then work through the property risks that apply to your address.
What should I check before renovating my home?
The cheapest time to find a renovation constraint is before the drawings harden. Clear the title, planning, hazards, structure, services and insurance questions while you still have room to change course.
What property-condition work should I do before selling my home?
A well-prepared sale starts with knowing your own home. Gather the records, understand the unresolved issues and make deliberate choices about repairs, disclosure and presentation.
How to read a home
A home becomes much easier to understand when you read three things together: what the documents say, what the building is showing you and what the likely work could cost. Start with the records you can get, use them to sharpen the inspection, then turn the findings into a short list of decisions and follow-up questions.
- 01DocumentsWhat the paperwork says the home is
- 02BuildingWhat the building itself is telling you
- 03DecisionWhat it will cost, when, and what to ask next
Read together, they show what you are buying and what is coming.
Common questions
What checks should I do before buying a house in Australia?
At minimum, arrange contract and disclosure review plus a building and pest inspection before an unconditional offer. A desktop read can triage earlier questions. Auction and private-treaty rules create different deadlines and protections.
What order should I do the checks in?
Read the disclosure documents first, form an early view of the building’s likely exposure (a desktop read does this cheaply), then commission a physical inspection on the property you are serious about, and settle your finance and price limit before any auction.
How much do pre-purchase checks cost?
It depends on the property, the state and the scope. Start with inexpensive steps such as documents and desktop triage, then commission the physical and specialist inspections the property warrants. See the building and pest inspection cost guide.
Do I need a building inspection if the vendor provides one?
Read the report and its fine print: when it was done, what areas were reached, who inspected, whether they carry insurance, and whether you are allowed to rely on it. Commission your own inspection when those answers leave a material gap.
How does condition evidence help during ownership?
It turns guesswork into a plan: what to maintain and when, what to tell the insurer, what a renovation will run into, and what a future buyer will ask. Keep it current as the house changes.
