I read a lot about it because I did not want to risk tenants health and everything said the best idea is to just leave it be if possible but that removal was generally not considered a big risk. 

For their health (and our liability risk) I am going to tell them they are required to move out for the duration of the remediation.  

The tenant moved out due to health reasons. 

If you intend to occupy but are prevented due to health and safety issues, that's ok.

Said agent or broker then contacts your broker and complains, with the inevitable threat to file a complaint against your license if it happens again.So....disclose.

If my health was my highest life priority and I was diagnosed with a serious illness would I take drugs?

Selling a little triplex I nursed back to health from a lot of years of bad management and neglect.  

Average tenancy is over 3 years per unit.Seller used to have 9 units and recently sold two units to the tenants. one for 32K and one for 35K. he wants to sell the rest all together due to health reasons.No deferred maintenance to past due HOA dues.

By the same token, being an informed consumer is important to your financial health.  

I have a one page cover sheet I add to each application with check boxes to show that they have the "deal breaker criteria", a section to score the "nice to have" criteria, and a section to briefly explain my acceptance or rejection.Our Criteria: Complete applicationVerifiable rental historySufficient income/resources to pay rent and liveCredit report showing prior addresses consistent with application We do not deny housing for race, color, religion, sex, national origin, handicap, sexual orientation, marital status, or familial status.We do deny housing to individuals:convicted of manufacturing or selling drugsconvicted of a crime the poses a threat to the property or neighborhood, including repeated disturbances, gambling, prostitution, violence, threats of violence, or rapewhere there is poor prior tenancy: evictions, violations, damage to rental property, poorly handled move outs, amounts are still owing to landlords or utilities.who misrepresent information on the rental application
