"We contracted with Jennifer Banner to purchase a condo in Snowmass Base Village recently. She was knowledgeable, and she listened to us and understood our needs, guiding us to the perfect location and unit. We did not know the area well, so her local expertise was indispensable to finding the right unit in the right location. She guided us to a unit that will not only increase in value in the long term, but one that will serve us perfectly in the short run. She is friendly and easy to work with, responsive and professional. We highly recommend Jennifer to anyone looking to find their mountain home."
