Anoint house with oil.!?

[Esaias]

Anointing inanimate objects was done in the Bible (Jacob's pillar, the furnishings of the Tabernacle, etc). But those anointings were ritual methods of dedicating the item to divine service. Anointing your home would indicate it is no longer being used for living quarters but has become an actual temple (if one was going to be Biblically consistent).

Of course, one might anoint a home for some other purpose, like "the X family is going to be living here" but again this would just be an act of dedication, like smashing a bottle of champagne against the hull of a new boat or ship, or cutting the ribbon and ceremoniously digging the first shovelful out of the ground on a new building project.

It has no "power against demons" that I can see. The Pharisees washed hands, bowls, plates, cups etc for essentially the same reason (warding against evil). Same reason Catholics splash holy water on homes and cars, or use oil during exorcisms of houses. It's remarkably similar to PAGAN SUPERSTITION.
