It's hard for me to believe she didn't know the payment was going to $3500 per month when she only makes $1800. What person making $1800 a month is looking at properety worth 600-900k making that much? How about looking at property at about 150k. These stories sound like BS.
You want to talk loan trouble, forget the stated deal, take a look at 1% option ARMS if you really want to see a train wreck in the making. Oh yea, you can get them stated too!
