But you have to be careful as they could be dangerous for your financial health if not used properly.

Most health issues with mold are in people that already have pre-existing issues (e.g. asthma) that is worsened by the presence of mold.Does the tenant see mold anywhere?

(As a landlord, I always do best to fix any issue.. other tenant live without any complain and she is the only one...she say she will report health department etc..)Sametime, She keep saying  she want to move to another apartment (1fl for her mother as her mother has some disability ) she wouldn't leave.I didn't like turnover and it is section 8, I was going to let her stay til she find the new home.

Those may help craft a plan for how to minimize the pain. 

Out of curiosity, anyone care to share their biggest pain points, gripes, or frustrations with building financial models?
