@Gwen Fyfe. It is consistent in its discriminatory requirement. ("we do not rent to close family members of tenants we have had to evict")
There is only one form of legal discrimination left: financial. If they cannot afford it or qualify financially, you do not have to rent to them. Any other form of denial can be open to a discrimination claim. "A close family member" ( or anyone for that matter) that qualifies financially cannot be denied in MOST cases. And you must use a qualifying process that is consistent and applied equally. A few exceptions I am aware of are:
Convicted pedophiles/ Megan's Law
Convicted Drug traffickers ( recent convictions/still on parole)
Sec 8 recipients ( you do not have to do repairs required by HUD inspector which will not allow HUD to approve your unit)
Recent eviction due to non payment of rent ( usually means they will not qualify financially.)
FYI: Just about any applicant that I did not want as a tenant does not make it through the application process' financial/credit requirements. But that does not mean a "bad" tenant does not slip through. I have other strategies to deal with paying but unwanted tenants. However, legally evicting a paying tenant is very difficult. You have to have a good amount of supporting DOCUMENTED evidence. Common sense clearly exposes bad applicants but find a legal way to deny. And if you are stuck with a "bad" tenant that pays, do what you can through your lease, local ordinances, police reports etc. to file a landlord-tenant action or make it "uncomfortable" for them to stay in your unit/house.
