The Sentinel (1977)

A fashion model moves into a house inhabited (on the top floor) by a blind priest. She begins having strange physical problems, has trouble sleeping at night, and has some nasty flashbacks of her attempted suicide. She complains to the real estate agent of the noise caused by her strange neighbors, but finds out that the house is only occupied by the priest and herself, and ultimately discovers that she has been put in the house for a reason.
