Last I checked it was around 90,000 which I think is okay for my barely upgraded house. Most of the points come from my using a full set on my main room, and all my villager pictures being on display.
When I checked this morning, my score was at 16,833. I've still only got one room in my house though, but I just asked Tom Nook to upgrade and give me a second floor after I saw I couldn't fit any more furniture in my room.
