Starting today, sellers who list their homes with a Century 21 agent will be automatically entered into the $8,000 List Your Home Sweepstakes.

The game is on for the next three months, ending June 30. Twenty-one winners selected in random drawings will each receive an $8,000 prize. “They’ll choose one winner per month in each of seven regions,” says Justine North of Century 21 American Homes in Bay Shore.
