“Mark DeSantis is the best. We had a house on 2 adjoining lots and 6 additional lots in Canal City on Bolivar Peninsula that we needed to sell. The sales included multiple problems with clearing, cleaning, repairing, getting wind certificate, contract changes, unforeseen events, buyer issues, many other things. Mark helped with every problem, knew a guy, interceded, had a solution, researched the options, made things happen. My gratitude and appreciation could not be greater. ”
