"We've got bleeding heart stories all over," he said. "But they're all true."
In the Stony Point-Villa Royale neighborhoods of southwest Santa Rosa, many residents have already cleared out.

Kathy Wagner, 55, said she's thinking of locking her garage door for the first time since she moved in. "It's kind of scary," she said.
Most people who do find housing are discovering that they must pay more for less. "Here we pay $1,190 rent. Our new place is smaller but we're paying $300 more," said Christine Chisholm, 25, who is living with her parents.
Though there is talk that arrangements might be made for residents to rent longer or even buy, many are so upset by the turmoil that they have no interest in staying.
"Are we angry? Yes," said Wagner. "Do we want to see karma happen? Yes."
Some have fallen ill. "The eviction flu," Wagner calls it.

"To come into a community like this and turn our lives upside down," Wagner said, "it's like a disaster."
