Ours is pretty modest. I also don't like heights so I don't put them up on the top of the garage roofline peak.
Just icicle lights along the frame of the garage door and net lights on the two bushes aside it, and then in front of the other side of the house net lights on two other bushes, some "lantern" lights, and a few LED christmas tree things. Wreath on the door, my wife's garden flag and decorative pillows on the chairs in front of the house, and a poinsettia. And then we're done with outside.
Indoor decorations are definitely more extensive. I get the job of lighting the Christmas tree because I'm OCD so it is a meticulous process, and then she's in charge of the ornaments or else I'd be standing there picking one up and asking her "where does this go?" and she gets really annoyed by that. Plus I'm colorblind so I have trouble picking out the red ornaments against the green tree. Where I think there's a gap, there's often a red ornament.
Although in typical fashion, it seems that every year brings a handful of new decorations, and every year it gets more extensive. Somehow I suspect that will continue, and 10 years from now it'll be a lot closer to Griswold status. Especially if we have a house we don't hate.
