What happens if a player lands on another player's mortgaged property in Monopoly?

If a player lands on another player's mortgaged property in Monopoly, they do not have to pay rent, as mortgaged properties do not generate income. The owner of the mortgaged property can still unmortgage it later by paying the mortgage value plus interest, but until then, it does not collect rent. Players can still trade mortgaged properties, but the mortgage status must be disclosed.
