The 2010 United States foreclosure crisis was a time when a lot of people in the US couldn't pay their mortgages. Mortgages are loans people take out to pay for houses. When people can't pay, their houses get taken away from them. This happened to many people in 2010 because the economy got worse, people lost their jobs and so couldn't afford to pay their loans anymore. A lot of people lost their homes and had to move away from their neighborhoods, which was really sad. This crisis caused lots of people and communities to struggle and some of them still haven't recovered.
