SILENT SCREAM (1980)

Rebecca Balding of The Boogens (1981) stars as a college student who needs to find some housing, pronto.  She takes a room along with a couple other students in a house owned by an old woman (Yvonne DeCarlo) and her son.  The house is actually the same one that is in the classic Spider Baby (1968).  People start getting killed soon after.  Cameron Mitchell (in like his millionth zero budget horror movie) and Avery Schreiber (all those Doritos commercials) play two cops trying to figure it all out.  The great Barbara Steele is also on hand in a very creepy role.  There's not a whole lot going on in the plot but the ending is pretty cool.  The film was actually shot in 1977 but was unreleasable, so it was re-shot in 1980 - only 12 minutes of the original film was used!  A movie being watched on TV in the film is actually part of the original movie.
