If anything this community suffers from too literal application of "rules of thumb."  

In both instances they do the initial screening on the applicants, and once they find someone who meets the minimum qualifications I still get the final say.

Bad tenants will avoid M2M like the plague because they know it places the landlord in control of the property rather than the tenant.Think of M2M leases as part of good management like screening applicants.
