Kristen Koby & Koi Tasaniyom Reviews

  • "Was so impressed with the video and slide show presentation of our condo that Kristen Koby and her assistant, Koi, created. The professional follow-up with the Realtor who saw it on MLS enhanced the visual presentation. Because of that it was sold long distance! Was particularly impressed in that Kristen Koby never oversold expectations. She kept us continuously informed on the progress of negotiations, but never led us to believe it was a "done deal" until it was. We knew exactly where we stood on the possible sale throughout the process. She didn't falsely build our hopes only to be disappointed. We really appreciated that.We were thrilled. Kristen Koby's pricing of our condominium was right on. It was high enough that it pushed the envelope but realistic enough that we got a full price offer - immediately! I have been told that the art of determining a realistic sales price that benefits both seller and buyer is one of the most important qualities of a good agent. It was important to us to sell as quickly as possible but to not lose money. Kristen fulfilled our goal! Kristen's assistant, Koi, was so earnest and valuable in maintaining communications with us and making sure everything continued to move forward to closing." - Denis & Carol Carey (seller)
