rselak@tribtoday.com WARREN — A downtown developer with a record of taking old, sometimes derelict, buildings and returning them to usefulness has acquired the former Mickey’s Army / Navy building with the same intended purpose. Mark Marvin’s Bull and Rhino Land Company LLC has come to terms with the Western Reserve Port Authority to purchase the strip-mall style building at 231 Main Ave. SW for $350,000 — a large chunk of which is forgivable based on the agreement the parties struck. The deal is structured like this: Marvin put down $35,000 toward the purchase price and the port authority is holding a $315,000 note it can forgive in part or fully depending on the level of investment Marvin makes in the property.
