Some tenants are a whole lot more likely to absorb a rent increase than others. If somebody has built a life in the property, filled it with furniture, and would need a fleet of moving trucks to leave, that matters. Real estate is a people business, and understanding tenant behavior is part of managing rentals correctly. Whether you’re investing in Cleveland, Detroit, or Memphis—or coming from expensive markets like New York City, Los Angeles, or San Francisco—you can’t manage rentals strictly from a spreadsheet. The numbers matter, but so does knowing your tenant.
