Do I really want to lend money to people who have bad credit, and who haven't taken enough steps yet to remedy that credit?

Among those remedies are both civil and criminal sanctions that may exist in your particular jurisdiction.

These coverages vary form and state.It sounds like you may be liable since it was an existing problem that you did not remedy by addressing the cause (repairing or sealing the foundation) or lessening the effect (vents or fans).If neither insurance company will cover the repairs, try to work with the renter to see if she will cover half the cost.

Whatever your damages are as per your lease, should be charged to the tenant unless there's some remedy to the damages (i.e. tenant finds replacement acceptable tenant, some set lease break fee, etc).

You are letting lost rent (more than likely far more than cost of cure)  exceed the costs of remedy.

That looks like the landlord expects the person to move out without being given a chance to remedy the situation, or for the landlord to follow eviction procedures. 

Utah’s required action level of 1.0ug, meaning there should be no risk of health concern under that.  2.24 is fairly low, however it does require remediation.

Unfortunately, I would have to recommend that you seek the advice of any attorney, as agents are not licensed to give legal advice, and breaches and remedies of contracts are beyond our scope of expertise. 

It is an unoccupied property that has been "winterized" and had "mold remediation done" according to the docs I was forwarded. 

To re-mediate issue, I hired a handyman and re caulked the shower.
