What is a granny flat?

A granny flat is a small self-contained living area built on the grounds of an existing family home. They are also known as a secondary dwellings and accessory dwelling units. They were named from the original purpose they initially served. Traditionally families would use these dwellings to accommodate their aging parents or grandparents. By adding a granny flat, helped keep the family together while giving everyone much-needed privacy. By adding a granny flat was a much more affordable alternative to aged care homes and facilities.

Granny flat costs? 

There are two ways to build a granny flat. One is buying a kit home; kit homes generally offer two bedrooms, a kitchen and toilet area and can roughly cost around $50,000. Keep in mind that a kit home may have other costs involved, for example, the cost of labour to build your kit home and the services of a plumber and electrician to get your kit home connected to existing power, water and waste as well as the cost of getting your kit home certified through council.

A conventional built granny flat

Can cost around $120,000 – $200,000 which typically includes the electrician, plumber and other services required to build a granny flat.

How can I finance my granny flat?

There are 2 common ways to finance your granny flat. As Alex Ritchie has said in her report.

1. Redraw on your mortgage:

If you have made extra payments on your mortgage and have a redraw facility, you can access the extra money you have paid and use it to finance your renovations. This can be a competitive option if you want to avoid the hassle of additional debt, such as putting your renovation on a credit card or taking out a personal loan. However, keep in mind that you will lose the benefit of reduced interest charges on your mortgage because your loan balance will go up. Some lenders will limit the amount and frequency of redraws, as well as charge fees to deposit and withdraw.

If you want to take the redraw route, but your home loan does not offer this feature, you may want to consider refinancing to a home loan that allows this. The issue would then be waiting a few more years to build your granny flat after you’ve made enough additional payments to fund this project.


· Access cash without taking on new debt

· Easier and faster than applying for a new loan


· No longer reducing your mortgage interest

· Can be fees or limitations associated

2.Personal loan for renovation:

If you don’t have the funds upfront, you may consider taking out a personal loan for renovation.

A personal loan may allow you to take advantage of flexible features – such as the ability to make extra repayments, choose between a fixed or variable rate and choose between a secured or unsecured the loan. Personal loan terms are also much shorter than that of home loans, although interest rates may be much higher.

If you were thinking of putting your granny flat costs on plastic, keep in mind that personal loans carry lower interest rates than credit cards. The average personal loan rate on RateCity’s database sits at just over 12.14 per cent, while the average credit card rate is 16.82 per cent.

There can be a range of ongoing fees associated with a personal loan, such as annual fees. Consider researching different types of loans and compare some that you think maybe the best fit for your financial needs and budget before making a final choice.


· Flexible features

· Fixed term to pay off loan

· Lower interest rate than credit cards


· Potential fees

· Higher interest rate than home loans on average

· Can add to existing debt

The family benefits of a granny flat can’t be overlooked either, whether that’s giving your adult children more privacy while they are saving for a mortgage to move into their own home, keeping loved ones close as they become more reliant on care or if you have family visiting from overseas it’s a great way to give them the space and privacy they need.

Building Granny flats

Not only helps with your investment but helps with the ever-increasing Problem of ‘’affordable housing’’ for those that cannot afford to get into the housing market or rent due to increasing cost of renting a dwelling, they finally have the opportunity to rent their own home in an area that they so choose, that’s otherwise too expensive to buy land and build a house

There are also greater potential benefits that building a granny flat could bring to the Australian economy.

Not only can it be beneficial to builders, but it creates jobs for electricians’ plumbers and other professionals in the building industry.
