Sotheby's International Realty

Our Heritage

Recognized worldwide, the prestige of the Sotheby’s brand is unparalleled. The acclaimed Sotheby’s auction house, established in 1744 in London for collectors of art and other fine possessions, expanded to New York City in 1955.

Kuper Sotheby’s International Realty inherited this iconic brand name, building on its centuries-long legacy by delivering unrivaled real estate services. Our reputation for quality service and expertise is unmatched. This is our unique difference. The properties represented by our network are exclusively featured in Sotheby’s auction house marketing programs, including high-profile client events, plus showcased in their signature publications, digital newsletters, and on sothebys.com. So while our brand is uniquely local, our reach is global and that means more exposure that connects sellers with qualified homebuyers all around the world.

Local Expertise Since 1972

Kuper Realty was formed in 1972 under the leadership of Charles Kuper, Jr. and his family. It began as a commercial brokerage and later expanded into residential real estate, with a focus on the luxury market. In 1978, Kuper was named the exclusive Sotheby’s affiliate for Central Texas, pairing its local track record with the international marketing and referral reach of Sotheby’s International Realty. It is our mission to be the leader of luxury real estate in Texas by providing service that exceeds expectations, delivering knowledge that surpasses the competition, and presenting progressive marketing and innovative technology that outperforms the industry demand.

Today Kuper Sotheby’s International Realty is led by J Kuper and has more than 350 associates, offices in Austin, San Antonio, Boerne and New Braunfels, and listings in more than 90 Texas counties.

Commercial Roots

Kuper started as a commercial firm, and that tradition is a big part of why I'm here. I bring commercial strategy, institutional transaction experience and a legal background to my clients, backed by a brand that's recognized everywhere and a referral network that reaches around the world.
