Condo Transaction in Moss Park, Toronto | May 2026

This is my second time working with Carolyn and she is amazing to work with. I am relocating from the United States and had to navigate the process remotely. Carolyn went out of her way to accommodate my needs, took videos and coordinated with my son in Canada to view numerous properties on my behalf and negotiated in my best interest. I will not hesitate to work with her when I am ready to purchase. - Catherine O'Leary

Condo Transaction in Cooksville, Mississauga | Apr 2026

Working with Carolyn was an amazing experience from start to finish. My fiancée and I went through a lot during our search, and she was incredibly patient and understanding every step of the way. No matter how many questions we had or how many places we wanted to see, she always made time for us and never made us feel rushed or pressured. What really stood out was how on top of everything she was. Carolyn was organized, responsive, and always one step ahead, making the entire process feel smooth and stress-free. She truly listened to what we were looking for and helped us find the perfect place that fits our needs and lifestyle. We’re so grateful for her dedication and support, and we wouldn’t hesitate to recommend Carolyn to anyone looking for a reliable and caring realtor. - Sergio Rios

Home Purchase in Meadowvale, Mississauga | Jul 2026

My wife and I recently purchased our first home and had the pleasure of working with Carolyn. Before meeting her, we had a few frustrating experiences and honestly were starting to wonder how much difference a realtor could really make. Carolyn completely changed that perspective. From the beginning, she showed us exactly what a great real estate agent brings to the table. She is highly professional, incredibly personable, and guided us through every step of the process with patience, honesty, and clarity. As first-time home buyers, that made a huge difference. What stood out most was how responsive she was. Her replies to texts were unbelievably fast, which gave us a real sense of confidence and support throughout the process. Carolyn is also extremely knowledgeable and was never afraid to tell us the truth about a property, the good, the bad, and the ugly. That kind of transparency is invaluable when making such a major decision. She was a huge asset in helping us buy our first home, and we’re very grateful to have worked with her. I would strongly recommend Carolyn to anyone, especially first-time buyers. - Joseph N

I’ve worked with Caroline and the Cynthia Ostos Team more times than I can count, for both houses and condos, and every time has been a great experience. Honestly, they just make everything easy. I keep choosing them because they’re reliable and know what they’re doing;and they always deliver. They’ve definitely exceeded my expectations every time, whether it’s timing, service, or results. The whole process from start to finish is always smooth. Communication is on point, and the team is super supportive the entire way through. They really take a lot of the stress out of it. I’d absolutely recommend them to anyone; family, friends, whoever. You’re in good hands with this team. - Brian Hastings

Home Sale in Collingwood | Jun 2025

We are absolutely thrilled to write this review for Carolyn, who truly went above and beyond to sell our home! Carolyn and her partner impressed us with their professionalism, deep market knowledge, and genuine dedication. Selling a home can be a stressful process, but Carolyn made it feel seamless and, dare we say, enjoyable. They didn't just list our house; they became a true partner in the process. Here are just a few examples of how they exceeded our expectations: - she sourced and hired someone to go through the house and organize/sell/dispose of all the items (we were selling my husband’s mom’s house, who had recently passed away) - she checked in on the house every few days to make sure everything was okay since we don’t live in the area - she personally helped us with all the junk removal once the house was sold - she has been continuing contact with us to make sure we are happy and everything is sorted We have worked with a few realtors in the past, and Carolyn is the only one we’ve been truly blown away by! We would highly recommend her to any of our friends and family in need of a realtor. Thank you, Carolyn! - Margaret Doucette

Carolyn is one of the rare agents who would discourage you from buying a house which is not the best fit for you as she always has your best interest in mind. It is not just a transaction for her but a relationship. We loved working with Carolyn to buy our next house as she tirelessly showed us properties that fitted our needs, pointed out any pain-points or problem areas which we may have missed and helped us see the potential where we needed help. Thank you Carolyn for all you do. Special shout out to Cynthia and her amazing team for the support that they provided. It has been such a great experience. I would recommend Carolyn to anyone looking to buy their dream home. - Farhat Khan

I haven't owned a home for a few years and I was quite apprehensive to begin my search in Toronto, especially during COVID-19. Carolyn took the time to really understand what I was looking for and what my non-negotiables were, and within two weeks of working together I had found the best unit I've seen in my neighborhood of choice! Furthermore, her and her team are very connected in the real estate industry and they have so many resources to help you with your purchase. I highly recommend hiring this agent! - Sarah Burke

We had the pleasure of working with Carolyn in our search for a condo in Mimico. She was nothing short of amazing, and was a perfect fit for my boyfriend and I. Before signing with a real estate agent, we had both thoroughly researched and interviewed other agents. The Cynthia Ostos Real Estate Team really stood out because of their professional appeal, knowledgeability of the Mimico area, and energy. I knew after our initial meet that it would be a perfect match. Carolyn was always quick with responses, and really took her time to understand exactly what we needed and wanted in our first home. As we are now moving into our condo, we cannot thank her enough, she has made this whole process a breeze. I highly recommed her to anyone looking for a real estate agent. - Veronica Sales & Michael Shmulevitch

The moment I reached out to Carolyn, we received listings from her (including our current place) within 4 hours. A day after that, we met and viewed the properties we liked. We're so happy with our new home and have Carolyn to thank for that. - Sahar
