Backdated Property Valuations for Tax, Legal and Insurance Needs

A Retrospective Valuation determines the market value of a property on a past date. At Propti, certified valuers prepare accurate backdated reports for CGT, stamp duty reassessments, insurance claims, estate matters and other compliance requirements.
If you need a current value for lending or transfer, see our Mortgage Purpose Valuations or Stamp Duty and Transfer Valuations.

​

What is a Retrospective Valuation

A Retrospective Valuation provides the market value of a property as at a specific historical date. Accountants, lawyers, executors and owners use these reports to establish the correct cost base or value at an earlier point in time.
Common use cases include

• Capital gains tax calculations for a prior financial year

• Establishing market value at the date a property first became an investment

• Family law or estate administration where a past valuation date is required

• Insurance or dispute matters that reference a value on a particular event date

​

Why an Accurate Backdated Valuation Matters

Using estimates for historic values can lead to tax errors, disputes or delays. A certified retrospective report ensures
• Defensible evidence of market value on the nominated past date
• Methodology and comparable sales that align with professional standards
• Documentation accepted by accountants, solicitors and authorities
• Confidence that you are paying the correct tax and meeting legal obligations

Frequently Asked Questions

1. What date should I choose for a retrospective valuation?
Use the date relevant to your matter, for example the date the property was first rented, the date of separation, the date of inheritance or the date required by your accountant or solicitor.

​

2. Can a retrospective valuation be done years later?
Yes. Certified valuers use archived sales evidence and market data to determine value as at the historic date, even many years after the event.

​

3. Will the ATO accept a retrospective valuation?
Yes, when prepared by a qualified valuer using accepted methods and supporting sales evidence. Our reports are designed for accountant and ATO use.

​

4. How long does a retrospective valuation take?
Most reports are completed within two to five business days depending on access, location and the age of the historic date.

​

5. Do I need to provide old photos or records?
They help. Any historic photos, plans or renovation dates allow the valuer to understand the property’s condition at the nominated date and can improve accuracy.
