New Tenant who would pay one yr rent up front

[Johan Yang]

Hello fellow BP,

I recently just closed on two properties in Orlando. One of my new properties is on the market for rent. My Real Estate agent has met with a prospective new tenant who is willing to pay one year rent upfront. This prospective new tenant is an ex-military (still young, in mid forties), married with a kid. He told my agent he has a ptsd syndrome and currently isn’t working. I think he said to my agent he gets medical allowance money from the military or something like that. My agent hasn’t run his background check yet. 

I would like some opinion what I should know about accepting the whole year rent money up front. Do I need a special lease agreement or add a special paragraph on the standard lease (what do I need to write), etc.

Has anyone been in the similar situation like this? 

Would it be very risky to have a ptsd tenant?

As always I greatly appreciate any inputs.

Best,

Johan
