More money problems for Plaxico Burress ... the ex-NFL star's mansion is in foreclosure after he allegedly fell behind on the mortgage, TMZ Sports has learned.
According to court docs filed in New Jersey ... Burress and his wife Tiffany stopped forking over mortgage checks on their 5,500 square foot pad back in July 2017 and the bank is looking to collect.
Property records show Burress and his wife bought the home back in 2005 for $1.5 million.
Now, the bank is demanding Plaxico and his wife pay the full balance on the home -- around $700k -- or they'll seize the property.
