To get an overview of the state of the pack you might have a look at this AHQ post, which shows a compilation of all open issues reported in connection with the For Rent EP:
https://answers.ea.com/t5/Bug-Reports/READ-FIRST-Compiled-list-of-reported-Issues/m-p/13277181/highlight/true#M262242
I guess the sections which refer to the owner tennant gameplay are of greater interest:
- Bills/Money/Royalty
- Property Manager
- Rental Event
- Residential Rental
Those sections contain some of the EP's widely known and stll open issues.
Note that these issues refer in general to an unmodded game. If you use mods, there might be more/different issues.
My personal opinion: Tomarang is a nice world, the BB stuff is good. CAS items are not as colourful as expected. The night market is a disapointment: pretty orphaned, only 4 stalls are functional, the rest is set dressing. The tiger sanctuary, the fish market and the temple are rabbit holes. I never touched the For Rent gameplay due to all the associated problems. I bought a code at a key reseller with a reasonable discount (50% off), but I wouldn't recommend it for the full EA price.
