Not sure how many PMCs you've had bad experiences with, but we'll take exception to:"Then do a thorough research on tenant applicants (note: leaving this to a PM may be hazardous to your financial health)".BP seems to have more threads about screening mistakes by DIY landlords as opposed to PMCs.Now, if you'd have mentioned Maintenance, you'd get no argument from me:) Even the PMC industry acknowledges maintenance as one of the biggest challenges.Rereading my post, I kinda see how I sounded negative toward PMs.  

Still need to screen S8 prospects though.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

@Sebastian NadalI've used Zillow Rental Manager to screen my tenants and have found it effective.

@Ashley Kehr I use a combination of Apartments.com for rent collection, RentSpree for tenant and background screening, and Stessa for accounting.

I would highly recommend moving your tenants to a PM software where you can screen tenants, collect rent, etc. 

Any tips on what to screen for specifically?
