Floyd Mayweather, boxing legend ... and landlord?!
TMZ Sports is told Mayweather has inked a massive, $402 million real estate deal to buy more than 60 buildings in New York City ... totaling more than 1,000 units around the Big Apple.
"Growing up I used to dream about owning just one home by myself, when you work hard you can achieve anything," Mayweather told us after agreeing to the deal, and sending a huge chunk of change to the sellers.
