As tax regulations evolve and property market cycles fluctuate across Australia, residential property investors are increasingly seeking clarity on property valuation requirements. Addressing a common query from property owners, Brendon Ptolomey, Managing Director at property valuation firm Herron Todd White, confirmed on a recent radio broadcast that retrospective valuations can indeed be performed—though they require rigorous historical analysis to meet Australian Taxation Office (ATO) standards.

Retrospective Valuations: What Investors Need to Know
Responding to listener questions regarding whether a valuation can be conducted for a past date, Ptolomey confirmed that property valuers frequently complete historical assessments. However, he emphasized the importance of engaging a Certified Practising Valuer rather than relying on informal real estate appraisals.
“Accountants will sometimes tell their customers to go get an appraisal from a real estate agent. That doesn’t comply with ATO requirements,” Ptolomey explained.
“Essentially, a retrospective valuation takes more time because we need to investigate the historical sales evidence on which we make our decision.”
Because valuation professionals must recreate the exact market conditions of a past period, historical valuations often carry higher costs due to the extensive research required.
Valuation Strategies Ahead of 2027
To navigate upcoming regulatory milestones—such as key compliance deadlines in July 2027—Ptolomey outlined an emerging strategy for property investors:
- Conduct a full physical inspection prior to compliance deadlines to establish baseline structural and cosmetic conditions.
- Issue an updated valuation report closer to the target compliance date, factoring in localized market shifts across capital cities.
With an estimated 3.3 million residential investment properties across Australia held by approximately 2.27 million individuals, and only around 10,000 qualified property valuers nationwide, securing qualified valuation expertise early is becoming a priority for compliant tax reporting.
The Valuation Dilemma: “Over-Capitalized” Homes
Beyond tax valuations, Ptolomey shared insights into some of the most challenging valuation scenarios encountered in the field—specifically, heavily customized or over-capitalized properties.
“When someone builds a massive three-story home next to single-story dwellings in infill suburbs, the hairs on the back of your neck stand up,” Ptolomey joked. “You sit there going, ‘How on earth am I going to value this?’ and ‘Who is going to buy this thing?’ Over-capitalization always makes us pretty nervous when rolling up the driveway.”
