"We could not have asked for a better experience in having someone like Gus Harshbarger to list and market our home. He builds trust through the application of his knowledge and experience, combined with technical savvy and data feedback to drive the entire process to a successful conclusion. We placed great trust in Gus to help us through a difficult market circumstance, and he delivered with honesty and integrity. We heartily endorse Gus to anyone who seeks a realtor who listens, communicates, and brings results.
Another integral partner in the whole process (referred to us by Gus) is our real estate attorney, Joan Dillon. Her compassion, experience, persistence, and negotiating skills were evident throughout, and absolutely essential in navigating through some difficult waters. Joan is a great advocate for her clients, and you can put your faith in her word.
We are grateful to have both Gus and Joan represent us in our latest transaction. We will lean on this great team for any and all of our future real estate needs. Highly recommend both Gus and Joan!"

"We would like to thank Gus Harsbarger for all his assistance with the purchase of a new home in Geneva for our family! We began the process by looking at homes in a particular area we were interested in, just trying to get an idea of the price and size of homes. Gus was glad to show us a bunch of homes and help us figure out what we were going to be able to afford. Gus knew that we were not in a hurry to purchase a home, and patiently showed us each home that met our criteria as soon as it was listed.

Gus was a great resource for us when it came to the different home prices. He was able to tell us when a home was priced too high, or when a home was priced right and would sell quickly. He also went through a distressed property and helped us in trying to purchase it. Ultimately, that purchase didn’t work out, but soon after we found the one we had been searching for!

Gus helped us through the bidding and negotiation process quickly and efficiently and we soon had a contract for our home. The process was smooth and well coordinated. We had never worked with the new digital documents that are all done online, but Gus made it easy. Gus was very professional, hard working, and dedicated to our family for the whole process. We were more than happy to purchase a home with his help and recommend him to anyone looking to purchase a new home!"
