Here’s an example of a listing of a 39 year old home where renovation is still in progress. They include product links to the new appliances they are installing now, and will update the listing once remodeling is completed. This is super common to see in used homes listings these days.

I do still see a lot of houses being torn down. But they are more like 50+ years old, and in such a state of disrepair that they are not worth saving.
