Mike Tyson -- Abandoned Mansion to Become Church

The insane over-the-top Ohio mansion where Mike Tyson lived and partied in the '80s and '90s is getting a complete makeover ... in Jesus' name.

The mansion is insane -- featuring marble EVERYWHERE, a hot tub with mirrored ceiling, indoor pool, tiger cages, a basketball court and more.

Tyson sold the place in 1999 ... and it's had multiple owners since then ... but now, according to the Daily Mail, it's been bought by a developer who plans to turn the property into a church.

The place isn't in terrible shape ... but it does need some work ... especially since vandals tagged the joint, leaving several "anarchy" symbols around the house.
