Family owned

Integrity Real Estate was built on a dream held by Bill Verhagen to establish a family owned and run agency in the Yarra Valley and surrounds. Now run by Bill and his Son William alongside our dedicated team.


What do our clients say?

“Great to deal with William was very patient, honest, knowledgeable (both in geography and sales history of the area) respectful and friendly to deal with. He was never overbearing or intimidating which made the whole transaction comfortable, easy and without anxiety. I would recommend William to anyone looking sell property in the Kinglake region”

“A Pleasurable & Supported Real Estate Experience Thanks Jane! You made us feel safe and supported throughout the process with your honest and straight shooting approach. You made yourself available beyond our expectations as we navigated such an important decision. It’ been refreshing to feel comfortable and valued during a realestate purchase, and to be able to share our family’s dreams with somebody so authentic and genuinely interested.”

How did it all begin?

Born and raised on a farm in Holland, Bill arrived in Australia as one of twelve children in 1960. Building his first house in Castella in 1976, Bill worked in the building industry for 25 years and contributed to some of the areas most significant landmarks. He then transitioned into Real Estate in 1995, working throughout the Yarra Ranges, Murrindindi and Nillumbik Shires. A few years later, the dream of Integrity had been fully realised with a team of professionals and three offices in the Yarra Valley and Kinglake Ranges. Integrity is a thriving Real Estate company who strive for excellence. The focus is a local and boutique approach with the support of industry class technology and training. Our staff are professionals in their field who take pride in their understanding of the local area and surrounds, being heavily involved in the community and advocating for the towns and suburbs they live and breath. The values of the company are reflected in its staff, all with the utmost honesty, transparency, trust, and most of all, integrity.
