A tenant's suspicion that s/he is not getting a good deal is toxic in this property class.

No tenant wants their rent raised, so she'll initially be irritated, for sure.  

Normally, nobody ever mentioned hearing tenants above them.Then, of course, came the tenant who ranted about how the guy above her deliberately stomped around to irritate her. 

Is the kind of mold they found, the kind that is toxic?  

My attitude was really aimed at the types of landlords that irritate me. 

After two weeks the tenant complained that there were toxic plants called angel trumpets in the yard and he would like them removed.

If you want to force a move you could raise it significantly higher, but you might irritate the tenants to the point where they don't take care of the property or worse, decide to damage it on their way out.Rent raises are easier for tenants to accept when they coincide with an improvement of some kind.

There were only a couple times when we had to have a tenant vacate their unit because of a problem - once because the plumbing overflowed and flooded the apartment; another time when the ceiling collapsed (I think because the tenant was banging on the ceiling with a broom handle because she was irritated by the noise from the upstairs tenant).But, in both cases, the tenants were no fun to deal with - even though our contract was very simple and clear on the fact that the landlord was not responsible for tenant belongings in the event of any kind of flooding, etc., and that tenants were responsible for getting their own insurance to replace their own stuff or pay for a hotel, etc., etc., etc.So, no you aren't liable for their stuff if there is a problem - but seriously save yourself a bunch of hassle by requiring insurance, including a loss of use rider.I live in low income senior housing now, and my neighbors are bad about overflowing plumbing, etc., and I can't even begin to count how often the smoke detector alarms go off because of old people leaving the stove on, etc.  

I've Posted While Irritated, especially early afternoon before nap #2. 

I will also probably be writing a lot of contracts before I get a "bite" which would irritate most agents.
