Kind Words From Clients

 Diana is a wonderful relator! I called her on Friday morning to inquire about a house I had seen online. That afternoon we went to see it. By Sunday she had assisted me in acquiring a preapproved mortgage and on Monday I was under contract. Her caring and guidance through closing made the entire transaction flawless. When I was ready to put my condo on the market, Diana again was invaluable! It sold in one week! Again Diana’s caring and knowledge shepherded me through the sale. I highly recommend Diana Fabia for all your real estate needs in and around Castle Rock, CO!
Wow! That's what I can say about working with Diana Pastor-Fabia! After buying and selling homes (over the least 20 years) in 4 states, we've had our share of great realtors but only a few that truly stand out, Diana is one of those. She not only got us a Full Price Cash Offer within 48 hours of our home's listing, but she also found us an awesome realtor in the Carolinas and coordinated with our SC realtor to close on both houses at the same at the same time, in Colorado before we left. There were hiccups that she smoothed out, issues that were quickly resolved, concerns rapidly put to rest and the list goes on. When you have to use a professional, don't settle, use the best you can find- use Diana Pastor-Fabia!
I cannot say enough good things about Diana. She was always available to answer questions and provided lots of guidance throughout. The house was listed quickly on a Thursday and I had 3 full price offers within 48 hours. It was under contract within 72 hours. She even watered flowers for me while I was out of town that weekend. I could not have had a better selling experience!
 Diana Fabia was a true blessing to our home buying process. She was steadfast in her commitment to helping us find the perfect home! She also gave us so much of her time in person, via text, and on the phone. When we finally found “the one” she helped negotiate the price as well as closing costs to finalize the deal. I truly believe she was a blessing to us and the best possible agent to propel us into the next phase of our lives as first time home buyers. I would recommend her a thousand times over and she will be the first person I call when our needs change. Thank you Diana!
Diana was fantastic. She listed my home and got it sold for maximum dollar amount in a tight window of opportunity. She staged the house beautifully, and even hired contractors to clean carpets that I thought could not be cleaned.
