DETROIT – Forbes magazine came out with its annual richest person list and Dan Gilbert was tops in Michigan (and 31st nationwide) with an estimated worth of $5.1 billion.

Gilbert’s Quicken Loans, the nation’s largest online mortgage lender, is now hawking Rocket Mortgages, a new Web and smartphone app to speed the approval process. Critics worry it could spark another real estate bubble. Gilbert continues to place bets on the city of Detroit, spending $2.2 billion to buy and renovate more than 80 downtown buildings and create a tech and entertainment hub in the Motor City, including a new light rail system he helped bankroll called QLine. He’s big in Ohio, too, where he owns the NBA’s Cleveland Cavaliers and several casinos.
