What is a granny flat?
An Acrow Investments granny flat is typically a small, 1 or 2 bedroom, self-contained housing unit located on the same block as a larger dwelling. A granny flat can be an ideal investment if you’re a homeowner looking to derive additional rental income from your property. It is a great solution for a family wanting a separate space for their growing teenagers or an elderly relative.
Investing in a granny flat is a smart, cost-effective way to acquire additional income from your existing property or create additional value for your home. The majority of Acrow’s granny flats are being rented for more than market value due to the stylish, high quality finish. Savvy investors have been coming to Acrow Investments for over 20 years to get their granny flat project off the ground.

Is building a granny flat a good investment?
A granny flat is one of the best ways to add extra space to your home, but more property owners are realising the investment potential that comes along with it.
Buying an affordable investment property is getting harder in Australia’s capital cities. With property values climbing higher, gaining a solid return on investment for a unit, townhouse or apartment is taking longer than many people are willing to wait.
Using your existing space to build a granny flat can be a much more affordable and stress-free investment option. A granny flat is typically more affordable than buying an existing property, which means you don’t have to borrow as much from the bank. A smaller loan is easier and quicker to repay, especially if you intend to use the granny flat as a rental property.
Learn how our customers turned their granny flat addition into a profitable investment.
Increase your property value
Granny flats are an easy way to increase the value of your property. Potential buyers will view your property as an attractive investment when they see the obvious benefits of the extra living space or rental income from your unit.
This is backed by research – in the 2019 CoreLogic/Archistart Granny Flat Report, a granny flat can boost your home value by 30 per cent and add around 27% to rental income.

Generate a rental income
Depending on your location, you could generate income from the on-demand market. Consider listing your granny flat on sites such as Air BnB – a great way to earn a steady income or some interim cash while you’re screening suitable renters.

Achieve financial freedom
In high-demand areas, such as Australia’s capital cities, granny flats can earn their owners hundreds of dollars a week in rent. Not only does this make the cost of the granny flat quicker to repay, it can help you pay off your existing mortgage faster and bring you closer to financial freedom.

Why invest in Central Coast?
The Central Coast is both a beautiful region and regarded as an investment hotspot. It’s only 1 hour’s drive north of Sydney, where the increasingly unaffordable housing has encouraged buyers to flock to nearby regional areas in droves. So, despite the nation’s recent property crash, the Central Coast has continued to experience steady growth in the real estate market.
Over the past year alone, that growth has been 3.8% on average. Prices are set to continue to rise. The current population of the Central Coast is approximately 340,000, which is expected to increase to around 410,000 by 2036. Of this growth, 55% is predicted to be people aged 65 and older and the area is expected to need more than 40,000 extra dwellings in the next 15 years.
