“'There’s just such an explosion in the rental market and it’s just not possible to find another place,' Maria Christina Blanco, a City Life/Vida Urbana organizer, said. Many who can’t afford their apartments end up on the street, with few affordable options for housing left to choose from, Blanco said. Many, she said, end up in shelters. 'It’s really about working-class tenants and homeowners being able to live in Boston and not being pushed out,' Blanco said. 'That’s what we think is really in everyone’s interest long-term.'"
