In order to be lenient for providers in essence or theory the apartment management would have to know she is a provider. I'm not thinking too many reputable apartments would knowingly want that activity occuring on their property. Are you asking what apartments have less restrictive or lenient leasing processes? I know many ask for at least the last 3 months pay stubs and do a credit check. I would probably go the private party route meaning trying to find a renter/owner of a property: apt, condo, trailer home that maybe a little less restrictive. Do your research, Trulia, Craigslist etc..many people are trying to find renters.
