Colin had a good grasp of the market with all the extra problems with the covoid virus. It is a very difficult to sell a property that is why an experienced real estate agent like Colin is invaluable .

We were lucky enough to meet Colin as our agent. He made his best efforts to make satisfy not only the vendor and also buyer as well. I could see he had a great relationship with the previous owner and we also could trust him.

Colin was courteous and professional on each and every occassion. We have no hesitation in recommending him when looking to purchase or sell.

From a to z he keep taking care about me, easy to contact, quick responds. He lead me the best way to have a contract and me, my wife satisfy so far. Still got couple of more progress but it seems no troubles at all. Thank you so much colin

Colin helped me a lot with selling my property while I was overseas. I would love to deal with Colin in the future due to his professional approach.

I would say among the real estate agents in Quakers Hill area, the service with Costigan is really top class. I had interacted mostly with Sacha Bayat from inspection till the end of buying process and he was very helpful and always answer your queries. He is friendly as everyone there and I would not hesitate to recommend Costigan to any of friends as I myself was referred by someone. I wish Costigan all the best and will have definitely association in future.

Colin has not only been a fantastic sales agent, he has also become a friend. The whole selling experience has been spectacular and he was acting not only in the best interest of the seller, but the buyers also. Colin is very highly recommended by us as we have used him a number of times, with superb results.
