Criminals or people with a criminal history are not a protected class. 

In both civil and criminal court?

You'll have to honor the existing leases through the expiration of their term (as long as the tenant hasn't breached for non-payment, etc) but can raise rents, terminate leases, etc. at the expiration of the term.I don't see much point in running background / eviction / credit / criminal checks on tenants that are already in the property.

(All have same addresses on drivers licenses/Identification)They have decided that the lease will be in 2 of the 3 of their names because the 3rd woman has past eviction in 2010 (7 years ago) so she will be an occupant but not on the lease and she has past traffic/criminal record (not sure if it is DWI or something else report doesn't specify) but she will not be on lease but probably indirectly paying rent to other women as she will be an occupant).Woman #1- qualifies income wise by herself 3x's the rent but has a ton of outstanding student loans and bad credit rated 515.

So I would advise that you learn a bit about better tenant screening; in PA, the state now has free internet searches for lots of important things pertaining to tenant screening, including criminal court records, landlord tenant magistrate records, and even traffic driving offense court records (useful for the tenant that drives for the first job or is Uber or Lyft driver on the side).

My motto is the best offence is strong defence.

Yes we do, if they meet all of our rental criteria (residence/rental history, income/employment history, financial/credit history, legal/criminal history)  and with additional security deposit to cover our risk. 

We do our credit/criminal/eviction checks via our state's LL association, and it is still a fax and paper process.  

We charge $32 per applicant for a credit/criminal/eviction check.

And run by criminals.
