A young couple from Glenwood who had been living with their parents saved up to buy 36 Fraser Ave. in Kellyville last June for $2.1 million.

The couple bought the property so their parents could move in with them later that August, but their parents ultimately decided not to move in.

Ten months later, they decided to sell the property because it was deemed too big for them, and the couple initially expected a price between $2.1 million and $2.3 million.

It was listed and sold through Ismail Ates of The Studio, who told The Daily Telegraph that his own projections for the property's asking price were "blown out of the water."

"We advertised the market on Friday afternoon and the next day 25 groups of buyers came to inspect the house - and after one inspection the house sold for $2.6 million to another young family who appreciated the size and appearance of the house."

"I'm just unhappy with the outcome, they made $500,000 on the sale of the property within 10 months of owning it for exactly the same terms as when they bought it."

"In recent months, young families across Sydney have admired Kellyville for its proximity to the upcoming Metro West line and the excellent schools in the area. The fact that this property backs onto a major road in particular has pushed up its value."

The four-bedroom and three-bathroom property is touted for sale as a family home with a mix of entertaining, landscaped gardens and a pool.

Situated on a 607 square meter lot, it has an oversized kitchen with high-end appliances, a walk-in closet with ensuite, and a downstairs study.

Kellyville was recently found to be one of Sydney's most in-demand suburbs in the last 12 months, with new PropTrack data showing that 20,000 buyers have been looking to buy property in the area.

The median price in the suburb has fallen slightly by 2.2 per cent over the past year - with the average purchase price of a home standing at $1,662,000.
