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 FTC is accusing Greystar, an apartment firm with a major Houston presence, of charging renters millions in hidden fees. How common are junk fees in Texas?

Greystar is the largest property management company in the U.S. and operates thousands of properties across the Carolinas.

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 U.S. Federal Trade Commission and the State of Colorado have filed a complaint against Greystar, a multi-family rental property manager, alleging that it deceived consumers about rental costs with hidden fees,

Colorado Attorney General Phil Weiser's office says that the suit specifically claims that Greystar uses deceptive advertising practices by failing to mention some mandatory, fixed fees in the advertised price for an apartment.

Colorado Attorney General Phil Weiser and federal regulators filed a joint lawsuit against the largest apartment owner in the country on Thursday, accusing it of intentionally misleading tenants about the cost of its rentals.
