The U.S. Federal Trade Commission has filed a lawsuit accusing property management company Greystar of swindling renters across the country out of at least $100 million using hidden fees.

Greystarwas sued by the Federal Trade Commission Thursday over allegations that the nationwide manager of apartment buildings, stuck renters with millions of dollars in hidden fees.

Colorado and the FTC say Greystar Real Estate and Property fraudulently advertises low rent prices to potential customers, only to add tens if not hundreds to the monthly rent cost with hidden fees.

The antitrust and consumer protection agency accused Greystar Real Estate Partners of deceptive pricing, charging tenants millions of dollars in unadvertised fees.

The FTC goes on to allege at some Greystar-managed properties, hidden fees are bundled together and referred to collectively as an "amenity fee", "community fee", or "lifestyle fee" without being further explained on a tenant's account statement.

The Federal Trade Commission will reportedly allege the apartment management company falsely advertised rental prices by not including mandatory fees.
