Trying to find the name of a movie that I think aired in the mid to late 1970's on TV about a family that moves into a house. The main women of the house starts getting gray hair/getting older and you notice the house is getting in better condition as people come to some sort of demise . I remember a scene near the end of the movie when the lady spins around (maybe in a wheelchair) at the top of the stairs and she is very very old and the house is beautiful with flowers blooming outside etc. Someone falls down the stairs from the shock of seeing her. I seem to also remember a creepy guy with a large smile (undertaker??). Anyway my husband and I were talking about movies that really scared us as young kids and we both started talking about this same movie and we would really like to watch it again. Would appreciate any help. Thanks!
