Karen is the best Realtor we have ever worked with (representing us both buying and selling), hands

Karen is the best Realtor we have ever worked with (representing us both buying and selling), hands down. Not only is she an astute professional, but she is remarkably kind, patient, and knowledgeable. She stays abreast of market trends, offers sound advice, is incredibly communicative, well connected, and really? Just a wonderful person. When we first started working with Karen, we were stationed on the east coast- so lots of calls, texts, even facetime to help my Husband and I find our first home together. With her guidance, we were able to beat other offers (during Covid and even using a VA loan!) and close without issue. Fast forward a few years and it was time to list our home due to a fast approaching deadline for work out of state. Karen got us set up quickly, realistically prepared us for the selling process, and got our home on the MLS rapidly. We recently closed from out of state, and it's Karen's expertise that made a stressful transition much more manageable. Through both buying and selling, Karen has consistently been there for us, and we couldn't be more grateful. She has always made us feel like VIPs, regardless of the price of the transaction, and we've felt genuinely valued and cared for. If you're looking for a Realtor who is knowledgeable, responsive, trustworthy, and genuinely cares about her clients, we cannot recommend Karen highly enough. She has, and always been, an absolute pleasure to work with. And you bet we will choose her again when we move back to the Valley!

Professional, patient and proven

Karen and her team were amazing to work when we recently sold our home. Karen & team did a real time market value on our home, did not set an unrealistic value or expectation on the property and timeline to sell. From the photos to market materials, every thing was first class. We had numerous showings every week during the listing period and multiple offers over the the time on market. Stacie was great with communication with all of the short notice showing requests and follow up during the sale. I would and do recommend Karen DeGeorge & partners to everyone.

Best buying experience I've ever had! I was buying a house in Mesa while still living in New York —

Best buying experience I've ever had! I was buying a house in Mesa while still living in New York — which, for anyone who's tried it, is already a nightmare. Karen made it easy. She set me up with a great lender, handled all the back-and-forth, and kept me in the loop the entire time. I never had to wonder what was going on. Her negotiating skills are also impressive. She got us a price and terms I didn't think were even possible. I still can't believe how well it worked out. I've bought and sold a lot of homes, and this was by far the smoothest transaction I've ever been through. Karen's "white glove service" isn't just a tagline — she genuinely lives it. Her team was awesome too. Responsive, professional, and just really great to work with. They went above and beyond. If you want someone who'll truly be in your corner and make the whole thing feel effortless, Karen DeGeorge is the one to call. I can't recommend her highly enough.

Jill was absolutely phenomenal throughout our home-buying journey! She went above and beyond to help

Jill was absolutely phenomenal throughout our home-buying journey! She went above and beyond to help us close, no matter what obstacle came our way. She was knowledgeable, responsive, determined, and always had our best interests at heart. Thanks to her dedication and hard work, we made it to the closing table. We couldn’t have asked for a better realtor and highly recommend Jill and the Russ Lyon Sotheby’s team!
