Trustworthy, open communication, extensive market knowledge. Overall great experience

The overall process of selling a property can be frustrating. However Austen’s extensive knowledge of the market, open communication and passionate drive to deliver results put my mind at ease at all times and gave me the confidence to trust completely. I highly recommend Austen to anyone selling their property.

Certainly would highly recommend to anyone!

We engaged Austen after our property has been on the market for longer than desired, Austen had the property sold within a month! Communication, market knowledge and follow up first class. I would be more than comfortable recommending Austen to other sellers

Sold 111/363 Beaconsfield Pde, St Kilda West

Austen Kosasih made it happen wasn’t going to get my price but he made sure I was going to be happy with the outcome. I started high then we slowly waited and few buyers were interested at the we end. Thanks to Austen for a great campaign you worked it to sell within 8 weeks too. He is efficient and continues to support the client to the end I would recommend him highly thank you Austen for everything
