    If anyone was born to sell real estate, it is Mark Costanza. This Corning/Horseheads native can trace his interest back to elementary school, getting reprimanded for selling candy to fellow students. He has always had the entrepreneur embedded deep down. Spending the summers in south Florida with his grandparents, helping them work on “flip” homes, got him hooked on homes and real estate in general, at such a young age. With the technology boom in the 90s, Mark thought it imperative to be on the cutting edge of the computer industry. After earning his degree in computer technology Mark has worked in fields as varied as BB sales for VZW as well as managment for VZW. Mark has developed a reputation as a great problem solver and a do-what-no-one-else-can-do kind of guy. Transferring his skills to real estate, Mark has achieved tremendous success for his clients.

    As an owner of a company that assists with water and septic tests for real-estate transactions, Mark has his hands in many angles of real estate, from education training to fund raisers, to flipping homes himself and improving the neighborhoods throughout the Twin Tiers. Mark is on the cutting edge with a superior online presence sellers and buyers utilize daily, he is E-Pro certified, GRI Graduate, Realtor Institute, Notary Public and your best source for any real estate needs!
