A Great Investment Opportunity for the Central Coast

Do you want to increase yields on your investment? In a CASH-POSITIVE property, with returns of over 15%?

Sydney’s housing affordability crisis is continuing to see the Central Coast property market boom. The NSW Valuer General revealed a 10.2% rise in land values within the Gosford local government area, for the 12 months to July 2016. Local real estate experts are expecting the rise to continue, due to strong demand and severe undersupply. NSW Planning Minister Rob Stokes has called upon builders and developers to create new and affordable housing solutions to help address supply shortages.

With substantial growth and development expected to continue across the Central Coast, along with increased demand and low interest rates, now is the time to invest in adding value to your Central Coast 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. On the Central Coast, a good granny flat can rent for $200 – $500 per week.

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. The Central Coast 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 the Central Coast click here.
