A Great Investment Opportunity for Penrith

While rising house prices and low supply have created an affordability crisis across much of Sydney, Penrith has maintained consistent growth while still being comparatively affordable. It also boasts access to infrastructure and lifestyle features such as sporting facilities, education, shopping, a national park, and rail connection to Sydney CBD.

Young adults and first home buyers who are being priced out of the property market in other areas, are being drawn to the affordability and facilities of Penrith. Others are seeking out affordable rental options in Penrith, while studying or beginning their careers. According to, a robust investor market means that approximately 50 per cent of Penrith residents are renters.

As a homeowner in Penrith, you have a great opportunity to capitalise on market demands in your area by adding a granny flat to your property. According to the CEO of Raine & Horne, properties can sell for a significant premium when they have a granny flat attached. Also, granny flats can yield a cash-positive return on investment through rental income. In Penrith, a good granny flat can rent for $200 to $450+ per week.

Whether you’re looking to add rental income, or to increase the sale price of your home, now is a great time to increase the value of your Penrith property by adding a granny flat.

Match this opportunity with the ease of adding a granny flat to your home. Not only can you expect to get returns on a cash-positive investment, you can usually get a construction or equity loan quite easily. Banks and financial institutions generally love granny flats because the homeowner already has equity in the property, and the repayments should be less than the rent earned.

Do I need to apply through council?

No. Penrith is covered under the State Environmental Planning Policy (Affordable Rental Housing) 2009, which means you don’t require a Development Application (DA).

Additionally, Rescon Builders have built many granny flats in the area and will ensure all aspects of your plans will meet the Complying Development Certificate (CDC) requirements, which are then approved by a private certifier before being stamped by the local council.

What Is Included In Rescon’s Services?

Rescon Builders are a one-stop-shop, handling everything from planning, approval and construction, all the way through to your finished & approved granny flat.

Quality inclusions are supplied throughout with all connections to the sewer, water and power. The only additional costs involved in building your granny flat are relevant council fees. These vary from area to area – for more information about council fees for Penrith, click here.
