mold issue in Atlanta

[Al L.]

I have a possible mold claim on a rental property in Atlanta.  The tenant said she might be sick because the house has a moldy smell. I am not aware of any mold issues prior to the purchase of the property three years ago,  The previous tenant didn’t say anything about mold, nor my property manager found any mold or water leak during the last property inspection.  I am not sure if the tenant's lifestyle contribute to the growth of mold.

My property manager will take a second look inside the house.  And I am planning to remediate mold as soon as possible after I receive the mold test result. 

In the meantime, the tenant wants to renew a two year lease.  She's on fixed income and has been paying consistently late for two years.  

Should I renew the lease?  Would anyone share your advice or thought on how you would tackle the issue as a landlord?  Thank you.
