As for Wells with the 100% financing. In Oregon, they have done away with everything but the Guaranteed Rural Housing. As such, it is not likely they have anything where you are for 100% unless you are in a farm type area.
Again, I will answer whatever questions I can help you with!
You are correct...the 100% financing is basically obsolete for now. Sadly, there were too many people who abused the opportunities. Therefore, the choice for banks to offer these products have been pulled.
As to bank versus broker. i am a broker...and as such my loyalty lies there. That being said, I always recommend that you talk with more than just your local bank. Whether another bank or a third party broker, you are more informed and will feel better and more secure.
Best of luck to you...I wish I could help! :-)

FHA does allow you to use Downpayment Assistance Programs (DAP) to have the Seller "gift" you the 3% down payment... but bank-owned & short sale deals are tougher with that.
Wells Fargo (and only them) has a program called CDMP that allows you to do 100% financing if and only if you meet very specific income limitations. Your 680 credit score is good but you need to be very careful not to do much for credit inquiries (don't go to 10 lenders) and do not open new credit accounts or rack up big credit card bills. 680 is teetering on the threshold where if it falls much you could end up paying a higher interest rate...
Russ Christian, a loan officer in my office, is quite familiar with CDMP and FHA with DAP if you have questions:
