Why invest in Newcastle?
According to the QBE Australian Housing Outlook 2018-2021, property prices have grown 7.6% per annum on average over the past five years. Rental properties in particular are booming, with Newcastle giving some of the country’s biggest returns on investment last year.
As professionals continue to migrate from Sydney, enticed by the natural beauty and relaxed lifestyle, they have powered a 27% increase in approvals of new dwellings from 2017-18. The The City of Newcastle LGA (pop. 155,000 and not to be confused with the larger Newcastle area) also offers many employment opportunities – approximately 73,029 people work there, and unemployment has been continually falling over the past several years.

HOW MUCH DOES IT COST TO BUILD A GRANNY FLAT IN THE NEWCASTLE AREA?
Building our standard two-bedroom granny flat with premium-quality inclusions in the Newcastle area starts from $99,000 (ex. GST). However, additional costs – such as council approval fees, land preparation and external works – will vary depending on your suburb, size of block and site conditions. We’re happy to arrange your free site inspection and no-obligation quote.
WHAT IS THE AVERAGE RENTAL RETURN OF A GRANNY FLAT IN NEWCASTLE?
With an average weekly rent of $400 to $500, adding a granny flat to your Newcastle property is an excellent investment. If you plan to arrange finance, a standard interest-only mortgage repayment will return a gross profit that averages around $250 to $300 per week. To equip you for your finance application, we’ll inspect your site, provide an obligation-free quote and prepare a rental return report – all at no cost to you.
DO I NEED PLANNING PERMISSION TO BUILD A GRANNY FLAT IN THE NEWCASTLE AREA?
No. As covered under the State Environmental Planning Policy (SEPP), building a granny flat in the Newcastle area doesn’t require council approval or planning permission. However, there are general NSW zoning rules and articles of state legislation governing the front and rear setback requirements that your new granny flat build must satisfy. As trusted local builders with almost 20 years experience in the Newcastle area, we are across all the rules. Give us a call to discuss your project.
