client love

Cassie was wonderful in helping our family find a new home. We were in the position of moving to the Denver area on a short timeline with limited opportunities to be physically present before the final move. Cassie facilitated our move as much as anyone could. She took the time to learn our preferences to narrow down the options to begin with. She walked through available homes we were interested in while taking videos and providing useful commentary for us to consider. When we were able to come to town for a short weekend, Cassie had nearly two dozen appointments lined up for us and was able to accommodate several others that popped up on the market during our stay. One of these last-minute additions became the home we made an offer on and eventually purchased. She was exceptional during the inspection/negotiation/closing process, keeping on top of required communication and answering our every question. You’d be hard-pressed to find a realtor more helpful than Cassie, and we’ll certainly be using her for any other real estate transactions in the future.
