These flats can be fully built for as little as $69,900. We also have 100% finance options available that can be paid in 7 years with repayments of as low as $85 per week! This is a smart financial decision especially as the granny flats price can be recuperated in a number of different ways:

  • Rent them out for up to $400/week
  • Reduce your overall taxable income
  • Add plenty of value to your property
  • Avoid land tax, strata fees, stamp duty, etc.

As well as this, granny flats are also a more affordable option than moving into a new residential property or renovating your existing household. They can be used for a variety of purposes too, including a home study, a bedroom for your teenager, or a retreat for your elderly parents. You can even move in yourself and turn your house into a rental property for even more income!
