Check credit, check rental history, verify everything, google them (check their social pages, do a background check, and require an increased deposit.

@Richard Daigle it would probably be a good idea to verify with your state if you're allowed to manage other's property without a license, unless of course you are.I use Appfolio for my PM software and really like it but I believe it has a 50 unit minimum now.

The IRS has been sending a bunch of letters 4883C requesting taxpayers to call 800-830-5084 and verify their identity.

You can always verify with your account as well. 

You need to be able to verify that the tenant is paying rent.

I told them to put the transaction on-hold while I verify. 

You'll also want to find comps to verify that you can get those higher rents once rehabbed. 

This should include some form of proof, such as a letter from their employer or even their employer's phone number so that I can call and verify.

If you choose to hire out individually, make sure you have someone near that can verify the work before you complete the payment.
