The Complete Property Due Diligence Checklist

Every OTP includes a period, usually 7 to 21 days, for the buyer to conduct due diligence. That window is your one contractual opportunity to inspect the property, verify the paperwork and pull out or renegotiate without penalty. Treat it as a professional process, not a formality.

The National Credit Act and the Consumer Protection Act give buyers some remedies against latent defects, but the practical reality is different. Voetstoots clauses shift most defect risk to the buyer. Recovery through litigation is slow and expensive. Prevention through due diligence is faster and cheaper.

Commission an independent home inspection from a qualified inspector (SAHITA-registered where possible). The inspector checks the roof, foundations, damp, plumbing, electrical, geyser age, windows and any structural cracks, and produces a written report you can attach to any renegotiation.

• Roof: age, waterproofing, gutters, ridge caps
• Foundations and walls: cracks, damp, subsidence
• Plumbing: pressure, drainage, geyser age and location
• Electrical: DB board condition, wiring age, earthing
• Windows and doors: seals, security, glazing
• Ceilings and cornices: staining, sagging, insulation

Certain compliance certificates must be provided by the seller at their cost before transfer. They are legal requirements, not optional extras.

Order a Windeed or LexisNexis title deed search to confirm ownership, mortgage, servitudes and any conditions of title. Confirm zoning with the municipality, especially critical if you plan to run a guesthouse, short-let or home business. Verify approved building plans; unauthorised extensions are the buyer's problem after registration.

Request the municipal rates account, water and refuse account for the last 12 months. For sectional title, request the levy statement, financial statements, reserve balance, arrears schedule and 10-year maintenance plan. For a rental property being sold with tenants in place, request 12 months of bank statements showing actual rent received, not the seller's claimed rent.

Depending on location, verify flood-line status, coastal setback (the coastal management line under the ICM Act), geotechnical risk (dolomite, subsidence) and any environmental servitudes. In parts of the Western Cape and Gauteng, geotechnical risk is a major latent value driver.

1. Build a written checklist before the OTP suspensive window opens.
2. Photograph everything at inspection, invaluable for renegotiation.
3. Talk to two or three neighbours; they know things sellers will not tell you.
4. For any rental in place, obtain the lease, deposit records and payment history.
5. For any sectional title, read the last two AGM minutes.
6. If in doubt, extend the suspensive window, a week of extension is cheap; a bad purchase is not.

• Skipping the independent inspection to save a few thousand rand.
• Trusting the seller's word on rental income instead of bank statements.
• Not confirming zoning matches how you plan to use the property.
• Ignoring building plans on older properties.
• Assuming the compliance certificates are current, check the issue dates.
• Letting the inspection window lapse without action.

A client bought a R3.4m home on the Atlantic Seaboard in 2024. Inspection revealed the deck extension had no approved plans and the geyser was 14 years old. Deed search revealed a right-of-way servitude the agent had not mentioned. The buyer used the inspection report to renegotiate R120,000 off the price and secured a written seller commitment on plan approval before transfer. Total cost of due diligence: R6,800. Net saving: over R100,000.

The FAQ block below covers what typical inspections cost, how long due diligence usually takes, and what happens if you discover issues outside the suspensive window (short answer: you generally lose the right to raise them, so complete the process properly and on time).

Due diligence is the single highest-return activity in a property purchase. It costs a few thousand rand and buys you the right to renegotiate, walk away, or proceed with full information. Every serious buyer we work with treats it as a structured project, not a formality, and every one of them has renegotiated at least once because of what it uncovered.
