It depends on the save, and the family I’m playing, I have aging off most of the time in my main save, and most of my families live on what they make. I do cheat with a few premades. I may add or change furniture occasionally, but not real often in most houses.
I have a couple of houses of some sims that are friends and I plan giving them there own apartments…… I love renovating apartments before moving people in, especially small ones with all of those wall units and stuff from DHD. I haven’t played the career yet, but I love the wall units in the pack, and the sofa’s.
In a legacy which I rarely play I probably do the most renovating.
In my main save I’m just as likely to move a sim to a new place ( usually renovating the new place first ) as I am to do big renovations at their current place. I don’t use mansions, but I have found some builders I like to use, so if the home or apartment becomes too small I will probably move them.
I started a scenario save ( about a month ago ), can’t remember what it was called, but it was with one sim. I made a female sim for Sulani, and within a day or two of playing her she won a lottery for a million dollars ( none of my sims in the past have won that!). So I’m sure I will be renovating her place or getting her a new place in Sulani, but since she won the lottery, I may send her to college first (move someone in temporarily to her house) before sending her to college.
