Jonathan and his team provided regular, ongoing feedback throughout all stages of marketing and the sale of our property. Jonathan’s attention to detail, frequent communication and robust marketing strategies gave us confidence that we had chosen the right agent for what proved to be a challenging market. I cannot recommend Irwin Property highly enough.

This was the second time we've sought Kate's services. We deliberately requested Kate to sell our recent property, as she has previously demonstrated her solid commitment to us, as her clients. Kate is always extreme friendly and highly professional, and has given us sound advise that resulted in a recent quick sale (at the first open-house!) at well above the anticipated price. We have no hesitation in recommending Kate's services and she will remain our own Estate Agent of choice, moving forward.
Seller of 7 Crommelin Pl, Chisholm
I was initially recommended to Kate as someone who knew the area and consistently achieved good outcomes for her clients. This was quite a challenging sale for me, being our family home for a long time, and Kate made the process as stress free as possible. Her valuation of the property was accurate and she achieved this price for me long before an auction, which I am positive would not have yielded a better outcome. Kate was very professional, but also compassionate and understanding of my needs as a seller. She was always available to me and kept me well informed on what was happening with my property. I am very happy I chose Kate to sell my property and thank her for her help and thoughtfulness, and achieving the best possible outcome for me.
Buyer of 173 Heagney Crescent, Chisholm
We can’t speak highly enough of our experience with Kate Coultas. We were first home buyers with very little knowledge about how to find the right one. Kate was honest, friendly and very professional in dealing with us. Kate was always available to answer any questions we had, no matter how small or silly they were. We highly recommend Kate Coultas from Ray White to anyone.

Buyer of 9/22 Dulcie Holland Crescent, Moncrieff
As first-home buyers, we were excited about the process, but a few things didn’t go as expected. We didn’t receive the main door key at handover, despite multiple follow-ups, and had to use the sliding door to enter and exit the house for a couple of months before finally replacing the lock ourselves. We also hoped for a more special moment with the traditional “SOLD” sticker, but received a “YEWW” one instead, which felt a bit out of place for such a milestone. We appreciate the overall effort but feel these small details could have been handled better to make the experience more memorable.
Seller of 59/53 Holborow Avenue, Denman Prospect
I engaged Jonny Warren to sell my property following multiple recommendations. Jonny was honest from the get-go and didn't play 'tricks' to get us to sign with him. His understanding of the market and marketing requirements was outstanding and resulted in the sale of our property within 3 days of hitting the market. Jonny is a down to earth and hard working person and this level of integrity is present across the whole team. Selling a house can be a daunting process, but Jonny and his team made the process easy.
Buyer of 5/121 Thynne Street, Bruce
Jonny is a very professional and reliable real estate agent. He provided me with excellent assistance and helped me successfully purchase my dream house. Throughout the entire home buying process, Jonny patiently answered my questions and provided me with practical advice on the home buying process and the local real estate market. He is very knowledgeable about changes in the real estate market and provided me with the latest market trends and price trends, giving me more confidence to make decisions. Jonny pays great attention to detail, helped me prepare and visit multiple homes, and explained the advantages and disadvantages of each home in detail, helping me find the perfect home. During the negotiation and purchase process, Jonny maintained a high level of professionalism and ethics, representing me in negotiations with the seller and securing the best price and terms for me. Overall, I strongly recommend Jonny as your real estate agent. He is outstanding and provided me with high-quality service and support, making me extremely satisfied with the home buying process.
