When Eric Rollo, 29, quit his job in higher education to focus on real estate, he and his wife agreed to a one-year trial where he’d need to at least equal his former salary. He accomplished that in three months. Rollo first dabbled in real estate when he finished his undergrad degree in 2008, but he hedged his bets in a brutal market by getting his master’s in applied psychology at Northeastern University. Today, Rollo puts on his counseling hat to zero in on his clients’ preferences. He conducts a thorough buyer needs assessment before embarking on showings. Along with housing requirements, the assessment covers proximity to schools, work, entertainment, and shopping. Rollo then identifies up to five target neighborhoods through a scoring system he developed. His aim: great service, great efficiency.
