Our Story
CASTO Residential Realty is a small, but dedicated group of Realtors® that have a strong passion for helping our exclusive network of resident family and friends find a house they can make into a “home”.
CASTO began building houses over 90 years ago and is now a successful commercial developer across Central Ohio. As part of the CASTO family we have an ingrained expertise and large scale insight on all things housing. We understand the construction industry, the local neighborhoods, the desirable schools, and even where traffic is a reason not to buy.
While the brokerage is boutique in size, it has the unique advantage of being backed by the power of the CASTO name and its’ relationships.
