Meet Abacus Real Estate

The team at Abacus Real Estate guides their clients through the process of buying or selling a home with an analytical, pragmatic approach. Led by Mary DeVries, a distinguished architect and top-producing agent, they calculate all the angles until they discover a property’s true potential.

Then they interpret that data so that clients can make intelligent decisions that serve their short- and long-term goals. Clients remark on the team’s uncanny ability to translate their desires into tangible results: they’re just as likely to call an engineer to get the real answer to a renovation or earthquake readiness question as they are to suggest an unexpected architectural style that ends up being the perfect fit.

When it’s time to negotiate, they bring in-depth analysis to the conversation and utilize their vast professional network and longstanding reputation in the brokerage community to get their clients the edge.
