CGT property valuations in Mandurah.

Why can a Mandurah retrospective valuation produce a capital loss?

Mandurah was one of the hardest-hit Australian markets after the 2013–14 peak, with values in some segments falling for the better part of a decade — so a property first rented out near the peak can have a cost base well above its later sale price.

This is a genuinely common and frequently missed outcome. Owners who assume property always gains, and so never obtain a valuation, can miss a capital loss they were entitled to recognise.

It cuts the other way too: a valuation dated at the 2019 trough produces a much lower cost base. Either way, the date determines the result, which is why we confirm it before quoting.

How is canal-front property valued?

Canal and estuary frontage is a primary value driver, and comparables must come from properties with genuinely similar water access.

Navigable canal frontage with a private jetty is a materially different asset from a canal-adjacent lot or an estuary outlook without access. The market prices those differences sharply.

Where a revetment wall or jetty was in poor condition at the valuation date, that liability affected what a purchaser would have paid and is reflected in the report.

How are holiday and second homes treated?

Mandurah holds a large stock of Perth-owned holiday houses, many later let short-stay or permanently — and each of those transitions can be a CGT valuation date.

Where a property was previously a main residence and then began producing income, the first-used-to-produce-income rule may reset the cost base at that date.

Where it was always a holiday house and never a main residence, no reset applies and the original cost base stands — which is exactly the distinction worth confirming before you pay for a valuation.
