Deciding what to buy
What Do You Need in a Home? Build Your Brief
Turn your household needs into a testable, five-column brief you can actually use at inspections — before listings start setting your priorities for you.
- A property buying brief separates genuine needs from nice-to-haves, written before you start looking.
- Write every requirement as a test — priority, reason, evidence, result — not a vague adjective.
- Revise the brief only after reviewing genuinely comparable market evidence, never to justify one property you already like.
Why write it down
A property buying brief is a short document that separates what your household genuinely needs from what would just be nice to have — written before listings, agent photography and open-home atmosphere start shaping your judgement, and useful at every inspection and for aligning with a partner or buyer's agent so everyone is working from the same document. Consumer Affairs Victoria's own buying guidance recommends deciding your preferred location and desired property features before you start looking, for exactly this reason. Keep detailed commute, school, service and neighbourhood-risk criteria in a separate location brief — this page is about the property itself.
What belongs in the brief
Cover purpose and likely household changes (start with owner-occupier versus investment priorities and accessibility and future fit); space and privacy (see space and layout); acceptable property types and your tolerance for shared obligations if buying into a strata scheme, body corporate or (in Victoria) an owners corporation (see compare property types and owners corporations); condition and effort (see condition and renovation tolerance); and only hard location boundaries that would rule a property out entirely — detailed area criteria belong in the location brief, not here.
The categories that matter
Non-negotiable — without it, the property doesn't work for your household.
Strong preference — meaningfully improves suitability, but you'd compromise on it.
Optional — worth having only if the price is right.
Accepted compromise — a limitation you're knowingly prepared to live with; see the property-compromises framework.
Unknown — something you still need to research or experience before deciding.
Rejection condition — something that rules a property out entirely.
Making the brief usable at inspections
Write each requirement as a five-column test, not an adjective:
| Requirement | Priority | Why it matters | Test or evidence | Result or next action |
|---|---|---|---|---|
| Office space | Strong preference | Regular work from home | Desk and chair fit without blocking circulation | Met / not met / unknown |
At each inspection, record the evidence against each row. For every item marked unknown, name the next check, evidence source or qualified professional responsible for resolving it — an unknown with no next step just stays unknown. Carry unresolved unknowns into property due diligence. Use the same brief for every property you inspect, and share one version with co-buyers or a buyer's agent rather than everyone keeping separate mental lists.
When to change the brief
Revise it away from an inspection, after reviewing genuinely comparable listings and inspections within your actual budget and search area — not in the moment, to justify one appealing property that doesn't meet a non-negotiable. Change one assumption at a time and record why.
Frequently asked
What's the difference between a buying brief and a due-diligence checklist?
A buying brief is about deciding what your household actually needs before you start looking — space, property type, condition, ownership obligations. A due-diligence checklist is about verifying a specific property once you've found one — title, contract terms, building and pest inspections. See property due diligence for that separate step.
How many non-negotiables should I have?
As few as genuinely necessary. Every item marked non-negotiable narrows your realistic search — a long list of "non-negotiables" that are really just strong preferences will eliminate properties that could actually work. Reserve the category for what truly rules a property out.
Practical checklist
Before your first inspection
- State why you're buying and which household changes are realistic
- Give every requirement a priority, reason and test
- Keep detailed geographic criteria in the location brief, not this one
- Carry unresolved unknowns into property due diligence and name who can verify them
