Diane Colburn helped me with the sale of my late mother's house at a time when I felt at my lowest due to the recent death of my mother. She is definitely the skilled professional you need when it comes to buying or selling a home. She makes the process so easy. Can't thank Diane enough for everything that she did.

We were very lucky to have Diane Coldburn represent us as our realtor. She was very knowledgeable and experienced with real estate, but was also a good-spirited person throughout the ups and downs of the real estate transaction. She always answered her phone and was attentive to things we asked her to look into, or communicate to the other party about. She worked very hard for us and allowed us to get the home that we wanted, even though there was a bit of negotiating that needed to be done. Without all of these traits, we don't feel we would have been able to make the deal, so we credit her with helping us make our dream happen.

Diane listened to what we were looking for and responded accordingly. She gave us great insight on the areas that we were looking at and was always available to answer any questions or concerns. Diane is professional, friendly, organized and well-versed in real estate and was able to guide us through the settlement process with ease. It was our pleasure to do business with Diane Colburn and thanks to her, we now have a beautiful home in an area we love.

It has been my good fortune to meet and work with Diane Colburn. I was looking for rental property, called Keller Williams to inquire about a townhouse I saw listed through them. Diane answered the phone and our connection began there. She met me the next day to go through the rental property, recognized how much I liked what I saw and that it was a good fit. Diane continued working diligently even after the showing, on my behalf. Long story short, I am now renting the townhouse!

Diane is the Best
I used Diane for a rental first, where she was great. I was out of state and she went so far as to go look at my first two choices personally. She supported me when I wasn't crazy about my landlord. I then decided to buy. She was super nice and also smart and effective. She got me the house I wanted. I REALLY wanted the house and she said "I'll get it for you," and she did. She made sure everything ran smoothly and is still helpful with things like finding professionals. She is probably the best realtor I ever had. She really had my back and I also felt like her skills and professionalism were huge assets.
Very Knowledgeable and hardworking
She handles everything with professionalism. She had solid market knowledge and I felt confident that my best interests were being looked after. If you want someone who cares, listens and delivers. Diane is your agent! I give Diane a 5 Star rating.

When you are ready to sell a house and plan to purchase another home it is very important to have a professional real estate agent assist you.We would highly recommend Diane to be your agent. She worked patiently with us. Whenever we had an interest in seeing a house, she promptly made the necessary contacts, and was always there to view the house with us. Diane was extremely knowledgeable in getting the correct answers to all our questions relating to the many homes that we went to see. When we were finally ready to sell she guided us through the preparations that would make our home marketable. We were amazed at how quickly she organized the advertisement for our home and the scheduling for buyers to see our home. When we found our new home, Diane provided outstanding assistance with the large number of administrative obligations that are required for smooth settlements. Diane is an honest and trustworthy person. We are so grateful that she was our agent. We would highly recommend her professional services in selling or buying homes. Harry and Theresa
