But while these properties promise big savings, they're often associated with regulatory red tape and financing complexities.Driven by a desire to achieve financial freedom, Danielle Lester decided to adopt tiny house living two years ago.She now serves as president of the volunteer-run Australian Tiny Homes Association (ATHA) but admits it's difficult to gather robust data about the number of tiny homes in Australia."Our membership base doesn't fully represent the amount of people who are living in tiny homes around Australia, and we find because of the regulatory complexity, a lot of people are choosing to do it under the radar, at their own risk," Lester told SBS News."Obviously, people have got no other option at the moment but to find a roof to put over their heads."In part, that's because there's no official national definition for what constitutes a tiny house in Australia He said another "hurdle" is that not all tiny houses follow the same construction codes, so for a long time lenders wouldn't take security over the property."There's no guarantee that the person who built the tiny home has done a good job
