We recently sold our home in Markham with Anjia Realty, and the experience was outstanding from start to finish.
Sara and Anjia team provided a very clear strategy from day one! from pricing, preparation, to marketing. They really understand the Markham real estate market and guided us step by step, which gave us a lot of confidence throughout the process.
What impressed us the most was how efficiently everything was handled. Within a short period of time, we received a firm, unconditional offer.The entire process was smooth, professional, and stress-free.
They also connected us with trusted professionals (lawyers, making it a true one-stop service. We didn’t have to worry about anything, everything was well coordinated.
If you are looking to sell your home in Markham or anywhere in the GTA, I highly recommend Anjia Realty. They dont just talk, they deliver real results.

We had an amazing experience working with JUSTIN DAI from ANJIA TEAM to buy our home. From start to finish, he was professional, knowledgeable, and incredibly supportive throughout the entire process. Buying a house can be stressful, but he made everything feel smooth and manageable by always being available to answer our questions and guide us every step of the way.
His expertise in the market, attention to detail, and strong negotiation skills helped us secure the perfect home with confidence. We truly felt that they had our best interests at heart and went above and beyond to make sure we were happy.
We are so grateful for all his hard work and would highly recommend JUSTIN DAI to anyone looking to buy or sell a home.🏠

We recently worked with Sara Qiao/Harry Siu and her team to both buy our new home and sell our condo in Markham, and we honestly couldn’t be happier with the experience.
After helping us successfully purchase our new house, Sara listed and sold our Markham condo very quickly and for a price above our expectations. In this market, we were worried about timing and pricing, but Sara’s strategy, marketing, and negotiation skills made a huge difference.
She truly understands the Markham condo market and the overall York Region real estate market. From pricing advice to staging suggestions to handling every step of the process, everything felt smooth, professional, and stress-free.

I’m so happy we chose Sara Qiao and Harry Siu and her team to sell our home in Boxgrove, Markham.
Our previous agent couldn’t get the property sold, and we were honestly very stressed. But Sara and her team came in with a clear strategy, strong marketing, and deep knowledge of the Boxgrove and York Region market. The difference was night and day.
They were professional, responsive, and confident from day one and most importantly, they got our home SOLD.

We recently sold our double garage detached home in Stouffville with Sara Qiao& Harry Siu and the Anjia Realty team, and the experience exceeded all of our expectations.
From day one, Sara demonstrated deep knowledge of the Stouffville real estate market and clearly explained the pricing strategy, marketing plan, and current York Region trends. Her confidence and data-driven approach gave us a lot of peace of mind.
Our home was listed for only one week, and we received a full offer that exceeded our expectations. The entire process was smooth, professional, and extremely well organized. We always felt informed and supported at every stage.
It’s clear why Sara,Harry and their team are recognized as York Region sales champions. Their expertise in selling homes in Stouffville truly shows in the results.

I honestly can’t thank Sara Qiao and Harry Siu and her team enough for helping me sell my home in Richmond Hill. I was very anxious at the beginning because the market hasn’t been easy, but from day one they made the whole process feel smooth and organized.
From advising me on pricing and how to list the property, to explaining every step clearly along the way, they made sure I understood exactly what was happening. I never felt confused or left in the dark. Every detail was handled professionally and efficiently.
What really impressed me is that they were able to sell my house in Richmond Hill within just two weeks. That gave me so much relief and confidence. There’s a reason Sara and her team are known as the # 1 Agent in York Region. They truly know the market and how to get results.
