They need verifiable income of some kind .

@Jestin Sorenson I'd ask for a T12 to verify all actual costs.

She's noted that they've been no trouble, but I want to verify that they check out according to my standards. 

You'll have to check with your 401k provider to verify though. 

Then go to credit karma, sign up for rental karma and they will verify with your "landlord" and that will put payment history on your credit.I once had to cosign for my sister, who made 3 times as much money as I did. 

@Edward Mahoney  You're correct that FHA is owner occupied and as memory serves me, it's supposed to be at least 12 months unless there's some verifiable reason like a job transfer.Don't fake the owner occupancy bit. 

They did the walk through and there were no problems and I called to verify.

I like that one because the landlord enters all the tenant info (SSN, etc.) which the tenant gets an email to verify. 

Just a couple quick responses (and I'm no expert so you should probably verify with one if necessary):If he doesn't pay and the building is collateral then you would have the right to foreclose, however, foreclosure in NJ can take a long time and be costly.

Of course, I verified the author was the property owner and called him and personally spoke to him to make sure he actually wrote it, and when I spoke to him he spoke highly of her.
