The Belle Property experience.
Read what our customers have to say about working with us in the testimonials below. Just as we did for these vendors, buyers, investors, and renters, we can help you achieve your property goals too.
We were very appreciative of, and impressed by the professionalism of Kosta and Kosti from the moment they first arrived to discuss our property and a proposed sales campaign.
They clearly took pride in their personal presentation, came with the information we required to make an informed choice about our preferred selling agency and respectfully guided us in determining our optimal marketing and sales campaign.
Throughout the selling process we were always respectfully consulted and advised as needed and were kept well informed through formal weekly update reports both in person and in writing. They were also consistently friendly, kind and warm.
There is absolutely nothing we would have changed and highly recommend Kosta Zaharogiannis , Kosti Kaptsis and Belle Property

Kosta, Kosti, and Jamie were absolutely fantastic to deal with throughout the entire process. Kosta was incredibly informative and offered valuable advice and guidance, which I truly appreciated—especially as this was my first time selling a property. He was always quick to respond to calls and messages, and both he and his team consistently arrived early for inspections. They made sure the house was presented perfectly each time and went the extra mile to ensure all lights were turned off and the property was securely locked up afterward. I’ll definitely be using Kosta and his team again in the future. Highly recommended!

Kosta and Kosti were great to deal with right from the get go, professional, transparent throughout the sale process. Their enthusiasm, energy and overall strategy was instrumental in achieving such a great result noting the amount of buyer interest due to the location of the house. In a suburb that has been dominated by one agency it was good to have been paired up with a new organisation in the area coupled with the motivated sales team created a much-needed breath of fresh air to the area.

Both Kosta and Kosti are professional real estate agents without the hype often associated with this profession. They build relationships with both vendors and potential buyers based on integrity and trust. We would have no hesitation in recommending Belle Property.

The Auction experience was relatively easy, it would have been 5 stars if the reserve price of the Vendor was made known earlier. It felt like it was an expectation which could have been made more transparent.

I interviewed 3 agents and found Kosta to be the most confident of reaching the desired amount that I expected and that he was patient and listened to what I had to say, as this was quite an emotional sale for me without going into detail.

5 Star service and execution, our agent (Kosta) is exceptional. As overseas owners, we were nervous about selling our house, Kosta communicated every part of the transaction is clear easily understood language and provided solutions to every single issue that popped up during the sales process. In Short he’s great!

Kosta provided the most exceptional service…well above and beyond the service anyone should expect! We live overseas and he managed absolutely everything, ie, styling, photography, advertising, viewings, negotiations but also remedial work that needed attending to for the house and garden, eg, lawn replacement and maintenance,, pool safety certificates, light bulb replacement. Since we built the house 7 or so years, Kosta is the only real estate agent that has maintained contact and kept us abreast of Adelaide prices, checking to see if and when we were ready to sell…he was a obvious first choice. Honestly, I cannot rate him highly enough! It was such a painless process and secured a great and fair price for both us as sellers but also the buyer. Thank you so much Kosta!!
