Birdman is selling the massive Miami mansion that once belonged to Scott Storch.

Baby purchased the 20,000 square foot, seven bedroom, 12 bathroom property in 2012 for $14.5 million.

He's listing the property for $20 million. Some of the price bump is on account of several million dollars of renovations the Cash Money boss did. (And stiffed the contractors on it.)

If  Baby gets close to the asking price it will give him one less excuse for not paying Lil Wayne and all the other folks he's f-ed over the years.

Here are some photos of the mansion.

Do you think it's worth $20 million?
