When you advertise your rental and when they apply you generally give them the terms that are important to them such as price, included utilities, pet policy, etc.

I have had tenants tell me I could not discriminate against smokers, had no right to verify employment, no right to look at credit scores, no right to restrict countless things but most often it is pets, no right to do inspections even though it is clearly spelled out in the lease agreement that they signed.
