Our Founder, Tanya du Preez

I love what I do. I help make dreams come true for my clients, whether it’s making owning their first home a reality, or helping them to improve their lifestyle through structuring their finance to help them get ahead. I love being part to their journey.

Tanya loves being able to make a difference in her clients’ lives, whether it is making their dreams of owing their first home a reality, helping them acquire an investment property or helping them improve their lifestyles by structuring their finance to help them get ahead. She loves being part of their journey. 

Strategic by nature, Tanya is focused on the big picture, helping clients use debt sensibly to achieve their goals. She believes a poorly executed strategy can be more dangerous than no strategy at all, so attention is paid at each step in the process.

From clients and their advisors, to lenders and other parties to transactions including real estate agents and solicitors, Tanya builds great working relationships quickly by delivering on promises and keeping the lines of communication open.

As a qualified Chartered Accountant with more than 20 years’ experience and knowledge of tax and finance, Tanya brings a unique blend of skills to the table. She is able to provide clients with insights and expertise across many disciplines helping unlock opportunities to achieve their goals.

Tanya, and her team’s focus is, and always will be, on the best possible outcomes for our clients as we work together for the long term.

A point of pride for Affinitas is that our clients come back to us as their lifestyles and goals change. Tanya is now seeing the next generation of clients come to us, as the children of our clients reach out to Affinitas Finance for help buying their first homes and beginning their investment journeys.

When she’s not at work, Tanya loves travel, reading and spending time with family and friends. Her happy place is wherever her favourite people are, especially if there is an espresso martini at hand.
