At Acumentis, we provide professional retrospective property valuations for a wide range of purposes, including capital gains tax, estate administration, family law and financial reporting. Our reports are prepared to be objective and supportable. This is the standard required for tax, legal and financial purposes.
Our national team of experienced property valuers combines local market knowledge with comprehensive historical research, drawing on property databases, archived sales data and council records to establish an accurate value for any specified past date.
A retrospective property valuation determines the value of a property at a particular point in the past. Unlike a standard current market valuation, a retrospective valuation (also known as a historical property valuation or backdated property valuation) is used to assess a property’s market value as it stood on a chosen date.
The valuation date, sometimes called the specified date or exact date, is set to a previous point in time rather than today. This is what separates a retrospective assessment from a current valuation, and getting the date right matters, since even small shifts in the local market can affect the outcome of the report.
Whether you’re calculating capital gains tax, resolving a legal dispute or preparing for estate distribution, a retrospective property valuation provides the evidence you need based on historical market value and comparable sales data from that time. This type of historical valuation of property is especially useful when the current market no longer reflects the property’s past conditions or value.
There are several reasons why individuals, businesses and legal professionals require a retrospective valuation. Common use cases include:
Capital gains tax is one of the most common reasons property owners require a retrospective valuation. If you’ve acquired an asset prior to CGT changes or you’re declaring a property’s value at the time it became income-producing, the Australian Tax Office (ATO) may require an accurate assessment of its historical market value.
Acumentis provides retrospective valuation for CGT purposes that aligns with ATO guidelines, delivering professional valuation reports suitable for audits, tax returns and financial records.
Acumentis is one of Australia’s most trusted providers of professional valuation services. When it comes to retrospective property valuations, we bring a level of expertise, national reach and regulatory compliance unmatched in the industry.
Our valuations are used by property investors, legal professionals, accountants and government entities across the country. Whether it’s a single investment property or a full portfolio, we can assess the value of a property at any specific past date.
Our goal is to make the valuation process straightforward and dependable. Here’s how it works:
We take into account market conditions, property characteristics and available sales evidence from the relevant timeframe to deliver an accurate and defensible result. In many cases, we also consider original valuations (such as those completed at the time of purchase) to provide additional context on how the property’s value has changed over time.
Costs vary depending on the property type, location and the amount of historical research required for the specific date requested. We recommend getting in touch for a tailored quote.
Yes. There's no fixed limit on the date in the past a retrospective valuation can cover, but accuracy depends on the availability of historical sales data for that period and location. For more recent dates, valuers typically have strong access to comparable sales and market records. For older dates, or properties in areas with limited transaction history, additional research may be needed to produce a reliable, defensible figure.
Yes. For CGT purposes, the ATO requires valuations to be objective and supportable. This means they need to be backed by solid evidence, not just an estimate. An independent valuation from a qualified property valuer, using recognised methodology and comparable sales data, is the strongest way to meet this standard. This applies whenever a historical market value is needed for tax purposes, such as when a property changes use or in certain deceased estate situations.
We can help clarify your requirements – whether you’re looking at the date of acquisition, inheritance or when a property became income-producing.
All retrospective valuations are conducted by certified practising valuers (CPV) accredited by the Australian Property Institute (API). Many of our valuers also hold AVI and RICS qualifications, reflecting international and industry-recognised standards. This ensures your valuation is prepared by a qualified professional and stands up to scrutiny for tax, legal and financial purposes.
In many cases, the cost base for an inherited property is its market value at the date of death. If no valuation was obtained at the time, a retrospective valuation can establish this figure using historical market data and comparable sales from that date.
Most retrospective valuations are completed within 5–10 business days, depending on the property type and available data.
We use verified historical market data, detailed comparable sales and expert analysis of market conditions at the specific point in time you're requesting. Each valuation is tailored to the property's unique characteristics and location.
Where relevant, we may also reference original valuations or compare the historical value to the current market value to provide deeper context. This ensures your report is defensible, compliant, and suitable for ATO, legal and financial purposes. A professionally prepared retrospective valuation report gives you an independent, defensible record for court, tax or lending purposes.
