Publisher Information

PurchaseWise is an independent Australian property calculator and buyer-education website. It is published to help Australians better understand the numbers involved in buying, owning and financing property — mortgage repayments, deposits, loan-to-value ratios, lenders mortgage insurance, stamp duty and settlement costs.

The site provides free calculators and plain-English guides designed to make property research easier. It is not a lender, broker or licensee, and it does not sell or recommend any particular loan product.

PurchaseWise is an independent educational website operated by an Australian proprietary company. It is not owned, controlled or endorsed by any bank, lender, government agency or industry body.

Tony Cowan is the responsible publisher for PurchaseWise. He is accountable for the editorial standards, methodology and accuracy of the calculators and guides published on this site.

Tony has worked in the Australian property industry for many years and is the founder and licensee of The Property Masters WA, a Western Australian real estate and property services business. His background includes real estate, property marketing, business ownership and property-related client services.

That on-the-ground experience with Australian buyers, contracts and settlement processes shapes the practical focus of PurchaseWise — and is why every page reminds readers to confirm final figures with a licensed professional.

Business Background

Parkrise Investments Pty Ltd is the Australian company that publishes PurchaseWise. Through its association with The Property Masters WA, the business has direct exposure to the real-world questions and cost surprises that Australian property buyers face — from deposit shortfalls and LVR thresholds to stamp duty deadlines and settlement adjustments.

PurchaseWise applies that experience to a national audience. The calculators and guides are written to reflect how Australian property transactions actually work, with clearly stated assumptions and links to the official sources that confirm the live numbers.

For questions, corrections, content suggestions or general enquiries, please use the Contact page on this website. That is the primary route for reader feedback and reported calculator errors.

You can also write to us at hello@purchasewise.com.au or PO Box 1421, West Leederville WA 6901, Australia. We aim to review and respond to genuine enquiries as soon as reasonably possible.

The responsible publisher oversees all editorial content published on PurchaseWise. Our editorial approach is set out in detail on the Editorial Policy page and the calculations are explained on the How Our Calculators Work page.

• Calculators use standard, well-established formulas with clearly stated assumptions.
• Guides are written in plain English and reviewed for accuracy and clarity.
• Government charges and stamp duty rates are sourced from official state and territory revenue offices.
• Advertising, where shown, does not determine calculator results or editorial content.
• Reader-reported errors are investigated and corrected where confirmed.

Property and finance information changes — interest rates, lending policies, government grants, stamp duty rules, tax settings and eligibility criteria all move over time. We keep PurchaseWise current through a documented review process:

1. Scheduled review. Mortgage and LVR formulas are reviewed against standard Australian lending practice at least annually. Stamp duty rates and concessions are rechecked against official revenue office publications as they are added, and on the review date shown on each calculator.
2. Event-driven updates. When a material change is announced (for example, a state budget stamp duty change or a first-home buyer scheme update), the affected guide or calculator is reviewed and updated promptly.
3. Reader feedback. Reported errors and corrections submitted through the Contact page are reviewed by the responsible publisher and addressed where confirmed.
4. Version transparency. Guides show a "last reviewed" date and methodology pages show a formula review date so readers can see how current the information is.
