They are referencing California code 1950.5 but that seems applicable only if a tenant satisfies the lease.  

I want to make sure this isn't a scam before we continue with the application. 

I think typically you'd provide the laundry machines (if applicable) and a fridge.

Starting to get my forms ready - renter application, etc  I want to have a system in place for this place and future investments.My question is what is the best background and credit report site?

Check the tenant application and payment history and complaint history of the tenants complained of. 

When you decide to move forward with a loan and submit an application, lenders will always run their own report.  

You can go online with the Search for Amazon jobs/riverview and there is an application and a phone number.

Hello BP,I am taking applicants for my first rental property.

Let me know if this thread helpshttps://www.biggerpockets.com/forums/52/topics/393652-screening-applicants-with-no-id-social-disabled-responsiblit

Even though they do good screenings, there are other ways they can turn off a good applicant, like how flexible they are to schedule showings, if they have multiple ways to accept rent payments (one of my PMs only takes money orders in his office, no exceptions; another PM won't accept move in date other than the first day of each month for easy bookkeeping from his end), or if they charge ridiculous non-refundable pet deposit and pet fees, etc.
