A pre-purchase property inspection checklist is what allows an investor to walk through a property systematically rather than emotionally, checking each structural, mechanical, and practical element against an objective standard before the agent starts selling. This checklist covers everything you should assess yourself at inspection, separate from and prior to the professional building and pest inspection you should commission on any property you intend to make an offer on.
Before You Walk In: External Assessment
The exterior inspection begins from the street. Walk around the full perimeter before entering. Look for: missing, cracked, or lifted tiles or metal sheeting on the roof; gutter condition (sagging, blocked, or incorrectly pitched); downpipes running to stormwater drains; diagonal stair-step cracks through brickwork from window or door corners (structural movement indicator); soft or leaning subfloor stumps if the home has a raised timber floor; and land drainage: does the slope run toward or away from the house?
Common Defect Repair Costs — Negotiation Inputs
These costs are negotiation inputs: a property with a $20,000 re-stumping requirement should trade at a corresponding discount. The professional building and pest report will identify and sometimes quantify defects. Your pre-inspection walkthrough primes you to flag them for the inspector’s attention.
Inside the Property: Room by Room
Check ceilings for water stains (brown rings indicate past or present leaks) and sagging plasterboard. Press firmly on internal walls around windows and doors: soft spots indicate moisture damage. Walk the full floor area with weight on your heels: springy or bouncy timber floors indicate subfloor issues. Check windows and doors open and close correctly: sticking suggests structural movement. In wet areas, check grout condition around tiles, press gently around shower recesses for soft tiles indicating water damage behind, and check under sinks for staining, soft cabinet bases, or mould. Test every power point and check the switchboard: old ceramic fuses in pre-1970s homes may indicate ageing wiring.
Termite Warning Signs
Look for mud leads (thin mud channels running up walls, stumps, or from the ground), damaged timber that sounds hollow when tapped with a key or screwdriver handle, and subfloor bearers with galleries if accessible. A professional licensed pest inspector will do this more thoroughly, but your own initial assessment helps you decide whether to invest in a report at all.
Frequently Asked Questions
Your pre-purchase inspection walkthrough is not a substitute for a professional building and pest report: it is the filter that decides whether a professional report is worth commissioning at all. Use this checklist systematically at every inspection, commit findings to notes rather than memory, and treat every identified defect as either a negotiation point or a deal-breaker. The professional report comes after: the investor’s discipline starts at the front gate.
