In many parts of the country the cost of rent is increasing faster than wages.Couple that with a lack of affordable housing and what you have is a growing problem in the rental market—evictions.Yet relatively little is known about the actual rate of evictions.Which is why national real-estate company Redfin decided to do some digging.

Which is what Redfin did, pulling court records from 19 states.“But the actual number is far greater, maybe even double that number,” she said.That’s because many evictions never make it all the way to court. People leave on their own, or maybe the landlord pressures them out.  For those that do go to court, the renter often ends up meeting a guy like Donald Rheubottom, a sheriff in the Baltimore City Sheriff’s department.  One cold fall morning  I accompanied him in his squad car across a series of Southwest Baltimore neighborhoods. He had a list of twenty evictions to carry ...
