Under these laws, landlords are prevented from using the source of the prospective tenant’s income as a reason to deny them a rental.

(Just be sure not to mention any other reason other than to obtain possession.)On a side note, fair housing folks hate it when landlords unnecessarily deny additional tenants unless there is a particular issue with local zoning or property maintenance codes.

(Or deny them because they have no rental or credit history...but be consistent.)As for suggestions on being successful at collections, here are some pointers:Evict quickly. 

Scott talks about umbrella policies and, while I think they are important, insurance companies are meant to deny you - they are looking out for themselves, not you.

People who are buying things like this from the internet should be denied immediately.

California is a problem state for renter abuse.  

The judge will get tired of issuing search warrants due to owners denying access.  

@Denis F.

Just because a particular short sale is not approved does not mean that all short sales will be denied.  

I don't even like landlords that take multiple application fees at the same time, run all of them, and then deny all but 1.
