So I agree with that is said above. If the tenant wants the house they need to ride the complex to make sure they get the forms. Else I tell the applicate that I am moving on to the next one till she gets all her stuff in.
We get 3 months worth of pay stubs and ask for bank statements. For 2 reasons, one we want to do an auto draft using Cozy.co (free landlord app) and 2nd I want to see how their money moves. If it is always overdrawn and they cant manage their money it's likely they won't pay on time, and it'll tell me how they will treat my house.
When we call the employer we make sure to call the number listed online, as it's not uncommon for them to give you a friends number and answer for them. If the company won't answer the questions I fax the release if they still won't, I let the applicate know I need this information and can move forward once they get that to me, and then I move on.
The other bit I use, is that I never decline anyone, you cant get sued if everyone is approved, I just make the deposit 3x, 5x or 10x the rent. Which means they likely can't come up with the deposit amount and I move to the next one. If somehow they have the cash, I will have enough to sue them and get them out and fix my house.
