Chad Acerboni isn't a full-time real estate investor. He's a tech sales executive who's been quietly building a portfolio on the side, one intentional move at a time. And his latest move? Selling his apartment complex, paying zero taxes on the sale via a 1031 exchange, and closing on a 30,000 square foot mixed-use commercial building for $2.1 million. The appraisal already came back higher than his purchase price.
