Why Invest in a Granny Flat in Sydney?

Building a Granny Flat on your property is one of the best investments you can make, especially if you live in the Sydney Metro areas and the Western Suburbs. It is no secret that Sydney has one of the highest median residential property prices in the world, and with such high mortgages, it’s no wonder that many Australians are turning towards Granny Flats as a savvy investment to make a better return on their properties. If you have idle backyard space, why not transform it into a practical, valuable home you could lease to pay off your mortgage faster?

From affordable student housing to luxury guest accommodation, secure elder housing to cosy Airbnb, the possibilities are endless when you invest in a high-quality Granny Flat in Sydney.
