Dolf de Roos was born in New Zealand, and went on to attend school in a variety of countries. Today, speaking six languages and holding business interests in a number of regions, he considers himself a citizen of the world. Over the years, as his successes with property became apparent, Dolf was urged to share the "why" and "how" of his real estate investment strategies. He has run public seminars throughout Australia, New Zealand, Asia, North America, and Europe, trained real estate agents, written and published eight best-selling property books including the New York Times Best Seller Real Estate Riches, as well as introduced software to both analyze and manage investment property. Consequently, his views on property are esteemed, and he is often asked to address investors' conferences, appear on radio shows, and take part in television debates.

In the late 1990s Dolf launched a public company, "Property Ventures Limited" of which he is the chairman. Property Ventures is now gaining momentum as an innovative property investment company, with holdings ranging from high-rise apartment buildings to high-end vineyards. Property Ventures is committed to increasing the wealth of its shareholders through the acquisition, development, and sale of real estate. Current projects are focused in New Zealand with several innovative property products having been developed over the past two years.

PVL plans to build shareholder wealth by concentrating on property development and investment through five major operating streams: New Urbanism which is commercial and residential property development in “green-field new urbanist projects”, Living Space which is expanding the brand name “Livingspace” with a goal of 700-1000 beds within 5 years.  They will identify and work alongside joint venture partners to develop other low cost but elite accommodation facilities. Development –Lifestyle Focus, which will identify and purchase property that, can be developed into a profitable and timely manner with a focus on underdeveloped property where PVL can see opportunities to increase value. Real Estate Investment Properties, which identify and retain key developed properties as commercial investments and ensure strong cash flow for the group and Wholesale Property Sales which sell commercial and residential property that has been acquired and developed by the company to pre-qualified investors.  Property Ventures Limited is an unlisted public company and currently has over 400 shareholders from around the world.
