CAMPBELL, Calif., Oct. 24, 2012 /PRNewswire/ -- Supporting many Americans' dreams of home ownership, Realtor.com, a leader in online real estate, today announced the launch of the Building Hope Challenge and is donating $50,000 to benefit BUiLD by Habitat for Humanity. The BUiLD movement aims to create a world where everyone has a decent place to live and advances Habitat for Humanity's mission of bringing people together to build homes, communities and hope. Realtor.com is a strong advocate of Habitat's mission and is dedicated to making a difference in a deserving community. While some people get involved in Habitat for Humanity by working on home-building sites, through BUiLD, volunteers can also participate via social media, purchase a BUiLD product, participate in a corporate-sponsored initiative, or spread the word to friends. During the Realtor.com Building Hope Challenge, participants will be able to nominate a state to receive a portion of the donation and, in doing so, be eligible for weekly prize drawings. The Challenge promotion is easy to enter. Participants visit: www.realtor.com/challenge, enter their e-mail address and select their state of choice. Participants can nominate a state once per day, and can share the promotion with friends via e-mail, Facebook and other social media. "We believe real estate is at the heart of a local community and the Building Hope Challenge will help revitalize a neighborhood in need of investment," said Steve Berkowitz, chief executive officer of Realtor.com operator Move, Inc. "Realtor.com is an advocate for the great work Habitat for Humanity has done over the years in providing housing for many families worldwide and providing support on a community level." The state with the most nominations per capita at the end of the Challenge will win, and a rehabilitation project of a local Habitat for Humanity affiliate in that state will be chosen to receive the designated portion of the Realtor.com donation. Participants may also donate directly to Habitat for Humanity.
