Is it weird to contact the owners of my grandparents house?

My grandparents sold their house in about 2000. My cousins and I all loved the house and have very fond memories of it. My grandparents have both since passed and while I would love to set foot in that house again, I know contacting the new owners is probably going to be bizarre.

I would love to send them a card just saying that I'm the granddaughter of the prior owners and that we had such a wonderful time in the house. I hope they are building wonderful memories like the ones my family has. I was going to include a couple photos we have of us on the front steps because the house is in the background, and another of all of us by the Christmas tree in the front window because the view is very distinct and wouldn't have changed much. I was just going to have my email there so they can reach out if they want to.

I just worry that it's going to creep them out and make them feel like I'm stalking them. I know the address, not their names. Is it weird or not?
