Army veteran applicant

[Vivek Kumar]

I got an applicant from army retired. Getting about $4000 and $2500 now as a consultant in a furniture company. He is alone and no pets. He has 1 year of rental history in an apartment leasing.  I checked his 2 year bank statements and looks fine.  His credit score is 620. He only have a auto loan with last 34 payments all on time.  

any red flags etc to check for? I have never had a army veteran as an applicant. So would appreciate any kind of thoughts
