A latch assembly comprising a tilt latch mechanism and a sash lock mechanism for a vinyl window that is slidable and tiltable. The latch assembly comprises a lever movable among a first, a second, and a third position to adjust the assembly among a respective locked, unlocked, and tiltable position. In the locked position, a portion of a rotor engages a keeper to prevent the window from being able to move. In the unlocked position, the window is movable upward and downward along the rails of the window frame. In the tiltable position, the window may be tilted on an axis to allow for cleaning the outer portion of the window from inside the house.
