Hip hop stars and R&B stars came out on Friday to encourage people to buy real estate, as an investment.  As the housing market continues to take a nosedive, the musicians say it is the right time to buy because eventually that home or condo you purchase will appreciate.  Hip hop entrepreneur Russell Simmons attended and spoke, as did Luducris, Gorilla Zoe and Yung Joc.  The event took place at Clark Atlanta University and the theme was "Get Your Money Right!".  Simmons spoke to the crowd on the benefits of buying a home, "With financial stability, it's a great time to buy when it's low. It'll pick back up in the long run."  All who attended received a booklet which stressed the importance of owning property, improving your credit score, plus more info for first-time home buyers.
