Investment Opportunityadd value to your property

Building a granny flat in the backyard of your home or existing investment property is a low risk, high return investment opportunity. Not only can you generate an income stream quickly, you also add value to your existing house and land.

Here’s why a granny flat is such a great investment decision:

Affordable, low risk investment

Building a granny flat is only a fraction of the cost of buying another property or building a standard home. A secondary dwelling on land you already own is the perfect way to kick start or accelerate your investment portfolio.

Earn a steady income stream

The low cost and high return of your granny flat makes it possible to positively gear your investment, guaranteeing you a steady income stream from the start even if you have to borrow to build.

Up to 25% ROI

Renting your granny flat, either to long term renters or on a short term holiday-let basis, has been shown to return up to 25%. And like your primary residence, your granny flat’s value is likely to increase with the ever increasing rise of Australian property prices.
