The lease should stipulate the the tenant is responsible for taking care of any accumulation of moisture and required to notify the landlord in writing if the problem persists.

I agree with the police dummy stuff to scare them off.otherwise persist with the eviction before lease ends

If they persist on wanting more money, tell them that your understanding is that what you've offered them is actually generous, but if they want a judge to decide that's up to them, and you'll be happy to abide by whatever a judge decides.  

In the end, we would rather have someone called pre-maturely than a potentially damaging (i.e. overflowing toilet) situation persist.

Nothing is ever 100%, but you can raise enough barriers that only the most persistent will get through all of them and by then you should have been able to protect yourself against them, again in so far as the law allows.That's probably not the answer you were looking for, yet so many people make the mistake of holding property in their own name, not using property managers, etc. that it is, indeed, worthy of concern. 

It's going to be a long and frustrating road, but it will get done with persistence on your part.

If he tells you that there are no bedbugs, which is damned hard to determine with any degree of certainty, then you find the infestation persists, he could be held accountable for your problem.You might talk to the inspector to determine if this is his real issue.

Both are now completed thankfully for persistence.

thanks guys n gals yep the lease agreement in this instance that she just signed says leased premises are for residential use not business use.. her argument is occasional client visits to her home are normal in her profession.we are still sticking to the presiding reasoning that disclosing the owner's SS# isn't warranted as the lease prohibits business use, thanks but she is being persistent and threatened to petition IRS that our owner's rent roll should be 'audited'! 

I don't blame him for trying.....whether he is persistent in pressing the issue is another story...!
