Private Owner House Rentals
tenant claims there is mold in apartment what do I have to do as the owner?
As an owner, you would need to have the mold that the tenant claims tested. You can be able to know if it is mold and get recommendations on how to solve the issue. You may need to do some replacement and repairs to take care of the issue. You can go to http://realestate.about.com/od/realestateinvesting/qt/mold_exposure.htm for more reference.
Get a sample and have it tested if you wish. Who tests it? Health department.
