I read somewhere to do understated tasteful Christmas like a wreath on the door and candles (no snowmen and lights) bake cookies for showing days. I'd keep everything nicely shoveled and looking easy to maintain

If not actually in the Christmas season, pine boughs and red berryies (even artificial ones) will brighten up a set of steps or a porch railing. don't go for artificial flowers, as that would be obviously 'wrong' -- but dried goods or evergreen (fir, pine, holly, etc) can be real or fake and still brighten the outdoors.

Have large planters of fragrant Balsam, white pine and spruce branches. You could also add long thick birch branches. Small clear lights nestled inside the pot will make the planters noticed at night. The planters will last outdoors from November until March in Ontario.

Thanks for the suggestions! I like the idea of the nestled lights inside the planters and using evergreens.
We are planning to list the house mid February.
