Sherrena saw all this, but she saw something else too. Like other seasoned landlords, she knew who owned which multifamily, which church, which bar, which street; knew its different vicissitudes of life, its shades and moods; knew which blocks were hot and drug-soaked and which were stable and quiet. She knew the ghetto’s value and how money could be made from a property that looked worthless to people who didn’t know any better.
