Selling Property · Koste Knowledge Base

What records do I need before selling an investment property?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Before selling an investment property, gather purchase records, sale records, renovation invoices, depreciation schedules, capital works summaries and ownership documents. These records help your accountant calculate CGT correctly.

Selling property requires good records.

Gather:

Purchase contract
Settlement statement
Stamp duty records
Legal fee invoices
Buyer's agent invoices
Loan documents
Depreciation schedules
Annual tax returns
Renovation invoices
Builder scopes
Appliance receipts
Strata records
Common property information
Sale contract
Agent fees
Advertising costs
Legal fees on sale
Ownership structure records

If records are missing, a CGT cost base report may help organise available information and estimate construction-related costs.
