:) I do have my own home so this one was extra, moving into that house would not make any sense. This sim will be retiring selling everything and moving to Sulani in a bit. There was yet another, a Ghost was scaring my tenant so I went myself, after I knocked on the door (Because I'm still a nobody there) the ghost enters right behind me, I'm clicking the ghost entire time, but I'm the second to reach the tenet, "Failed", so apparently my rental's rating lowered.
So again it seems the only way to correctly resolve these alerts is to use the phone and pay a tremendous amount. The best middle ground I've found so far is to use the phone option for an expert, pay a tremendous amount and every few weeks ********* myself the money I've spend in the last batch. If the rentals problems happened at the same rate as the players home that would be fine, if those costs for the professionals were the same, that would be fine, And the main reason, the income from the rental, unless it is coming and I'm somehow *Not Noticing, that hasn't happened even once.
Overall, the rentals do bring in more income, always use the phone option to resolve the many problems, I cant tell if the upgrades to the plumbing and electrical have any bearing at all, the favoritism to the rentals occupant that was encouraged, I cant tell if that has any effect other than acquiring another friend, the owner should know how to pay themself back for all of the problem costs plus income that doesn't come. Once all of those are dealt with... it IS more income, most likely what everybody was wanting in the first place. Unfortunately, the state of that expansion seems to require playing outside of EA's intended method, otherwise it's a headache with no benefit.
