First time landlord- nightmare scenario?

[Ben Mendelsohn]

Hello, I am I first time landlord and just ran into what sounds like a big problem that I was really hoping someone could help advise me on. My tenant stated that she saw mold so I had someone come out to assess the problem and this was their response...

"This property has an aggressive case of Microbial Growth. The property was without power for a week after Irma. It’s possible this started the growth. The tenant keeps a very clean house but growth is identified on every surface. My recommendation is to relocate the family, schedule an air quality test and then out together a plan for mitigation. The thermal cam registered elevated moisture readings through out the property with humidity levels in the 50-60% range."

The property is in Jacksonville FL and did not experience any flooding. I am pretty sure mold was excluded from my homeowners insurance policy and the recommendation of seems very drastic to me. I am just starting out and am worried that this is going to be extremely costly. Can anyone please advise me???
