martinmspedersen  Please open the EA App, click Sims 4 > Manage > Manage add-ons, and see whether For Rent is on the list.  If it is, and you can download it, do so; let me know if it's listed as already installed.

If the pack isn't present, clear the EA App's cache and look again.

It's also worth clearing the cache and repairing the game (under Manage).
