Lead Exposure Allegation

[Gabe Barlow]

In one of my properties, a tenant is alleging a child tested for lead exposure.  The property was tested today.  It appears this might be excluded from insurance coverage, and I am trying to look through disclosures and contracts about lead issues.  Obviously I am not aware of any lead issues, which was in the lease and acknowledged by the tenant.  

My question is, what are my options? Im feeling a little anxious over it all.
