Review status: the evidence register is the product

The register remains current because it records source and status. Planning, title, building and tenancy evidence must still be obtained for the exact jurisdiction and property.

  • Record the source and review date beside every transaction-specific input.

Government rules, thresholds and property information can change. Confirm current eligibility and transaction details with the authority, lender and relevant licensed advisers before acting.

Due diligence is evidence, not reassurance.

Due diligence is the work of checking what you are actually buying and what may affect ownership. The exact investigations depend on the property, state, contract and your circumstances, so use this as an organising framework rather than a substitute for professional advice.

PROPERTY

Condition, layout, inclusions, defects, services and any relevant building or pest reports.

DOCUMENTS

Contract, title, disclosures, approvals, strata records and conditions requiring legal interpretation.

CONTEXT

Planning, local supply, amenity, environmental considerations and factors affecting use or demand.

What must be independently checked

01

Confirm the listing facts

Verify the address, price, availability, inclusions, land or internal areas and what is represented by images or plans.

02

Inspect and investigate

Arrange the inspections and reports appropriate to the property type, age, condition and proposed use.

03

Review the legal position

Have an independent legal professional explain the contract, title, restrictions, deadlines and risks.

04

Check the ownership plan

Confirm finance, insurance, property management, expected costs and the evidence behind rental assumptions.

Evidence register

Assign every important question an owner, source and status.

A due-diligence checklist becomes useful when it records evidence rather than ticks. Copy this structure into a spreadsheet and retain the document or written response supporting each conclusion.

What title and restrictions apply?Current title search, deposited/strata plan, easements and covenants.Conveyancer or solicitor.Unresolved until explained in writing.
What exactly is included?Contract schedule, inclusions, plans, specifications and variations.Legal adviser and buyer.Marketing material alone is insufficient.
What is the physical condition?Appropriate inspection reports, photographs and defect records.Qualified inspector.Cost and response recorded for material findings.
Are approvals and use consistent?Council/planning records and relevant approvals.Appropriate planning/building professional.Do not infer approval from physical existence.
What shared obligations exist?Strata records, budgets, minutes, levies, insurance and by-laws where relevant.Strata reviewer/legal adviser.Known and proposed liabilities separated.
What supports rental expectations?Dated comparable evidence and a property-specific appraisal.Local property manager.Estimate, not guaranteed income.
Can finance and insurance proceed?Written conditions, valuation position and insurance quotes.Lender/broker and insurer.Pre-approval is not treated as unconditional approval.
What remains unknown?Open-question log with deadline and consequence.Buyer coordinates.Unknowns remain visible; they are never scored as favourable.
FHP evidence labels: mark each item Verified, Estimate or Unresolved. Also record the source date, because availability, prices, approvals, rental evidence and finance conditions can change.

Investment Property Due Diligence: questions to resolve

Is a new property exempt from due diligence?

No. New property has different checks, including contracts, plans, inclusions, delivery and developer or builder information.

Can an agent or seller replace independent advice?

No. Their role and interests are different from those of your independent advisers.

What if information is missing?

Treat the gap as unresolved. Ask for the document or evidence and understand the consequences before proceeding.
