104 Fern Street, Gerringong for sale with a price guide of above $6m

Its "unprecedented" views aside, the 'Cloud Nine' penthouse is also proving appealing to investors, as it comes as part of the whole freehold building with four commercial tenancies on the ground level and basement parking.

The property is located at 104 Fern Street, Gerringong and for sale for the first time in more than 20 years.

The Cloud Nine penthouse is approximately 686sqm, and features three bedrooms and two bathrooms

The penthouse's features include a roof top lap pool, extensive outdoor terrace and private lift access.

The selling agents are Greg Crumpton and Terry Digger from First National Coast & Country.

Mr Crumpton said they were considering offers over $6 million.

"It's smack bang in the centre of town, with amazing views," he said.

"It's an amazing apartment... It's probably the best apartment south of Sydney Harbour."

Mr Crumpton said there had been interest in the property from both Illawarra and Sydney-based investors.

Mr Digger said prospective buyers were drawn by the apartment itself, as well as the views and ongoing income it can generate from leasing of the commercial tenancies.

"The views are amazing... there's rural, mountain and ocean views," he said.

"They're unprecedented views anywhere on the coast."
