"Cathie Lee is an outstanding real estate agent! I'm so happy to have her represent me in selling my house. Cathie Lee is very friendly and patient. She is very knowledgeable in what she is doing and always answers my questions in a timely manner. Cathie Lee's talent in staging up my house is amazing. With her hard work and her artistic ability my house looks much more beautiful and presentable.

Cathie Lee is trustworthy and reliable. She is very resourceful with all the services I need in repairing and yard work before sale. I would for sure use her service again in the future, and definitely I would recommend Cathie Lee to my friends and relatives."

I was referred to Rosa Scalio by a family relative. Rosa is very professional, understanding, and trustworthy. She has many years of knowledge in real-estate and her performance has been very consistent. Rosa was very attentive and understanding of my needs during the search for my future home. She made the whole process a lot easier and less stressful. Rosa has been such a pleasure to work with from beginning to end. Her communication and attentiveness to my home-buying experience has been excellent. She took her time to explain everything to me and always went above and beyond. I am very grateful for her patience and for helping me close my first home. I would definitely recommend Rosa to my family and friends

Great job selling our home at full price. Cash sale provided us with the much needed quick escrow.

I was told "If you want to sell your house quickly, try big agent", that's true. My house at 567 Melrose Street went to Escrow in 8 days after listing, and 1535 S Diamond into Escrow in 1 day! That's amazing. Good Sales Record shows capability of agent. Cathie Lee definitely with sound record. She understand your needs and requirements and give good suggestion on marketing plan. A mutual understanding and co-operation is very important to reach the goal. I'm lucky I have a good agent and get my houses sold quickly.

Professional with efficiency and good sales result!

It's a nice home, but we're not sure whether we can get it sold quickly. The selling experience is excellent! We did right choice to select Cathie as our agent.

Bill was the best realtor we could have asked for. He and his teammate, Cathie, were so helpful every step of the way. They made sure we were comfortable with the process all along as it was our first time selling a house. I can't recommend their team highly enough!

After interviewing 3 realtors, I choose to list my home with Century 21, Team Scalio.
After signing the agreement to list my home; Bill was very helpful with suggestions of minor improvements and helped me find skilled contractors to do the work. I had relocated out of the area and Bill and Cathie Lee coordinated everything and kept me informed daily by phone or email as to the process and progress in getting the home ready to list. Bill took great photos of my home and Cathie Lee staged the home to highlight its best features. He is highly knowledgeable and can explain all the paperwork in layman's terms. He is highly motivated to get homes sold, After 7 days I accepted an offer and started escrow. My home sold and escrow closed in 20 days. If you're looking for a trustworthy realtor, Bill is your man.

West Covina | Seller Rating

We first met Bill when we bought our home 4 years ago. He happened to be the Selling Agent for the home at that time. After my wife and I decided to sell our home, she remembered Bill and the "Scalio" team. My wife decided to contact them and use them as our Selling agents.

The experience working with Bill and Cathie have been phenomenal. Their knowledge of the housing market was very educational and not to mention their excellent knowledge of the Diamond Bar area. They definitely overextended their services and did their best to make it stress free as possible.

We are in search for another home to buy and we have the Scalio team on our side.

Anyone looking for an agent, please definitely contact the Scalio team.
