Floyd Mayweather Jr. lands a knockout pad above the Vegas Strip

Floyd Mayweather Jr. knows his way around a knockout, particularly when it comes to real estate.

The welterweight boxer’s main base of operations, the 22,000-square-foot “Big Boy Mansion,” has spawned its own Instagram and Twitter accounts. He also stakes claim to high-rise spots at the St. Tropez Condominiums in Sunny Isles, Fla., and the Ritz-Carlton Residences at L.A. Live. And Mayweather can now call the Palms Place in Las Vegas home, having recently paid $1.81 million for a penthouse unit above the strip.

Found on the 55th floor of the high-rise, the 3,142-square-foot unit has custom lighting, hardwood flooring and wood wall treatments. Walls of glass take in unobstructed views of the downtown cityscape and surrounding valley.

Among highlight features is a telescoping glass wall that separates a living room and a game/billiards room. There are two bedrooms and 2.5 bathrooms, including a master suite with a sitting area, a fireplace and a large soaking tub.

An infinity-edge spa extends off of a private balcony toward the Vegas skyline.

The penthouse previously sold in July 2014 for $1.065 million, record show. The latest transaction occurred outside of the Multiple Listing Service in December.

Mayweather, 47-0, has maintained his status as boxing’s top draw, banking $105 million in earnings in 2014, according to Forbes. The 38-year-old will take home $180 million in Saturday’s bout against Manny Pacquiao, who is set to earn $120 million for his efforts.
