The DuBry Group
Two Generations. Two Principal Brokers. One Commitment to You.
Betty DuBry and Brandi Wagner bring the strength of a mother-daughter partnership to real estate across Mercer County, the Grand Lake region and surrounding Ohio and Indiana communities. Their combined perspective, local connections and hands-on brokerage experience offer clients a personal approach to buying, selling and investing.
From a first home to a commercial property or a place on the lake, their goal is to help clients move forward with clarity and confidence.

More Than a Team. A Shared Legacy.
Betty and Brandi are both principal brokers of Master Key Realty, bringing decades of real estate experience, longstanding relationships and deep roots in the communities they serve.
A Mother-Daughter Partnership Built on Experience
Working together as The DuBry Group means clients benefit from two experienced real estate professionals who share the same commitment to attentive service. Their partnership combines Betty's extensive background in brokerage ownership and professional leadership with Brandi's experience in residential, commercial, lake and land transactions.
Both have deep connections to Mercer County real estate history. Betty and Brandi worked with Owen Hall, whose brokerage legacy became part of Master Key Realty's story. Betty purchased the brokerage in 2008, Hall Realty and Century 21 Master Key Realty joined together in 2018, and the company became Master Key Realty in 2024. Today, their work together carries that local legacy forward.
Ohio REALTORS Presidential Sales Club
The DuBry Group has earned state-level sales recognition through the Ohio REALTORS Presidential Sales Club. These team awards reflect the work Betty and Brandi do together for buyers and sellers and their shared commitment to serving clients throughout the region.
For the team, professional recognition is meaningful - but the relationships behind every transaction matter most.
Real Estate Expertise for Every Chapter
Residential Real Estate
Buying your first home, moving to fit a growing family or selling a property filled with memories calls for thoughtful advice. Betty and Brandi help clients understand their options, navigate negotiations and keep the details moving toward closing.
Commercial Real Estate
Commercial transactions require careful attention to location, property use, timing and long-term goals. The DuBry Group works with buyers and sellers considering business, investment and other commercial real estate opportunities.
Lake Properties
Grand Lake St. Marys is more than a destination; it is a community with its own real estate considerations. The team brings local familiarity to the search for lake-area homes, waterfront properties and opportunities around the lake.
Land & Rural Properties
From rural homesites to larger parcels, land transactions often involve details that differ from a typical residential sale. Betty and Brandi help clients ask the right questions and make informed decisions about their property goals.
