Client Reviews

I met and hired Katherine to sell our house two weeks before we moved to another state. She came highly recommended and did not disappoint! She recommended cleaning people, handy men and lawn service people and they were great. She staged my house and we got an offer 8 days after we listed. We did everything either over the phone, through email or text. She is professional, trust worthy and kind! I would hire her all over again. We closed a few days ago and the entire selling process was painless.More

Katherine listed and helped us sell our home in Aug. 2016. She did a wonderful job for us. She was always on top of things and making sure things got done. She always kept us informed during every step of the process and whenever we called and left a message she returned phone calls quickly. She is very easy going and friendly. Just a pleasure to work with and a really nice person. So glad I got to know her.More Less

My agent Katherine Zellerbach went far beyond what was required of her. In fact, it has been two weeks since closing and she is still running interference and smoothing out problems for me. She is the best.

Katherine Zellerbach is an excellent realtor. We were extremely satisfied with her commitment and service to selling both our house and a vacant lot. We reside outside of the U.S. and she always kept us up to date.

Katherine made home selling seamless and virtually effortless. Being 2000+ miles away, Katherine made the long-distance sale stress-free. I would highly recommend Katherine to anyone looking to buy or sell a home in the Ft. Huachuca community.
