Thank you so much for your wonderful and thoughtful words! We were so happy that you were able to get your offer accepted in such a competitive situation. When we learned about the tree falling in your yard we felt so bad; of course we would jump to your aide and do everything possible to assist you through such an awful and unexpected situation! We are here to take care of our clients throughout the Real Estate process AND BEYOND! We were happy to hear that the contractors we connected you with were able to get the tree out of your yard and get you reconnected with electricity. We hope it is smooth sailing for you from now on and wish you much happiness in your wonderful new home! Best, Karen and Seth
