I have to agree with Jonathan. The dangers of mold are dramatically exaggerated, and sometimes completely false.
Get a professional company that handles mold remediation. Have them check the entire home, not just the areas you are aware of, and mitigate the issue altogether. Talk to your insurance provider to see if this qualifies for a claim. Mold remediation can be expensive, but it may not be big enough to justify an insurance claim. They may even pay for the tenant to stay in a hotel until the home is safe again.
As for the tenants, I think you've gotten yourself into a pickle by letting this go long enough that they can claim health issues. It's always best to handle mold issues quickly and completely before the tenant gets the chance to claim you're killing them. However, I wouldn't worry about a lawsuit. You are dealing with the issue quickly and professionally.
The tenant told you the home is causing health issues. Give them the option of breaking the lease without penalty. This allows them to be safe, and it empties your home so you can mitigate the problem. If the tenant insists on staying, that indicates that they don't really believe there's a health risk.
I think your PM is incompetent or maybe just inexperienced. Regardless, you need a PM who takes the bull by the horns when issues arise. Whether it's mold, COVID, or a non-paying renter, a quality PM acts quickly and decisively to protect people, property, and the landlord.
If you feel the PM was negligent in their response, you can file a complaint with the state commission. I don't know if this rises to that level, but it's something to consider, particularly if the tenant does sue.
How to find a quality PM
Start by going to www.narpm.org to search their directory of managers. These are professionals with additional training and a stricter code of ethics. It's no guarantee but it's a good place to start. You can also search Google and read reviews. Try interviewing at least three managers.
1. Ask how many units they manage and how much experience they have. Feel free to inquire about their staff qualifications if it's a larger organization.
2. Review their management agreement. Make sure it explicitly explains the process for termination if you are unhappy with their services, especially if they violate the terms of your agreement.
3. Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers. It may sound nice to pay a 6% management fee but the extra fees can add up to be more than the other company that charges 10% with no additional fees. Fees should be clearly stated in writing, easy to understand, and justifiable. Common fees will include a set-up fee, a leasing fee for each turnover or a lease renewal fee, marking up maintenance, retaining late fees, and more. If you ask the manager to justify a fee and he starts hemming and hawing, move on or require them to remove the fee. Don't be afraid to negotiate, particularly if you have a lot of rentals.
4. Review their lease agreement and addenda. Consider all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.
5. Don't just read the lease! Ask the manager to explain their process for dealing with maintenance, late rent, evictions, turnover, etc. If they are professional, they can explain this quickly and easily. If they are VERY professional, they will have their processes in writing as verification that policies are enforced equally and fairly by their entire staff.
6. Ask to speak with some of their current owners and current/former tenants. You can also check their reviews online at Google, Facebook, or Yelp. Just remember: most negative reviews are written by problematic tenants. A tenant complaining online might indicate that the property manager handled them appropriately, so be sure to ask the manager for their side of the story.
7. Look at their marketing strategy. Are they doing everything possible to expose properties to the broadest possible market? Are their listings detailed with good-quality photos? Can they prove how long it takes to rent a vacant property?
This isn't inclusive but should give you a good start. If you have specific questions about property management, I'll be happy to help!
