Stuart - we do not identity check the people who are signing up to post to the forums.

When they apply is when you should confirm their identity.  

Social Security also has a consent based ssn verification process where a SSN can be verified with the parties consent.Again, we can never be 100% full proof but we can stay on top of the latest ways to mitigate the fraudsters at their game.How are you catching fakes?

Quote from @Ben Russell: Although I agree the leases and the legal implications of "Mid-Term" rentals and "long-term" rentals are closly related, I don't think the leases should be identical. 

Verify if there are additional adults or other violations.

@Seidy Lasker Wash sale rules apply to stock options if they are deemed "substantially identical" to a security sold at a loss within 30 days, such as options with similar expiration dates or strike prices.

Are all units identical? 

Verifying last 2 years of rental history very important!

LLC offers better legal protection.3) Setting up in states that allow your identity to be hid is also overblown.

You also didn't state anything about how you verify income.We get a YTD paystub (only need one!)
