White Folding Chairs Around Coffin, Changing Stair Ornament

Can you help me find a 70's or early 80's horror movie with the following elements:

1. Lake with fix-up house(es)
2. Stair ornament that faces the other way around
3. Secret room with dead people, a coffin, and white folding chairs
4. Traps in the woods with spikes
5. A red front door
6. A sweet old neighbor guy who turns out to be not so sweet.

Thanks.
