But Rangel has been living since the 1970s in Harlem’s Lenox Terrace apartment complex, where he improperly amassed four rent-stabilized properties.

State law requires that rent-regulated apartments be the tenant’s residence.

“I will reside in the Property (on 132nd Street) for at least six (6) months of every calendar year,” read Rangel’s mortgage contract with Citibank, which is on file with the city.

The terms of the $60,000 loan appear to be normal for that time, but lenders say claiming principal residency when you live elsewhere is a serious breach.

“It’s fraud or a mistake,” said David Reed, an author of several popular books about mortgage lending.
