Fannie Mae and Freddie Mac have a secret blacklist of properties they won't touch

Freddie Mac and Fannie Mae have created a confidential blacklist of around 1,400 properties that don't meet their new criteria, which came about following the collapse of the Surfside, Florida, condominium in 2021. Properties on the list are either financially unstable or haven't kept up with maintenance. The list, only accessible by lenders and servicers, leaves potential buyers and those looking to refinance with higher interest rates or struggle to get mortgages. The lenders say the list only affects less than 1% of properties and is intended to protect borrowers from unsafe or financially unstable properties.
