U.S. property management company Greystar swindled renters across the country out of hundreds of millions using deceptive advertising and hidden fees, according to a lawsuit filed Thursday by the U.S.

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

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