I do think you need a realtor to help you out with this, however. Truth is it won't cost you a dime and they can really help. Let me know if you do not have one and I can refer you a great one. Call us if you need to get prequalified!
Best place is on the MLS.
Usually, at least in my experience, if there are no pictures it's due to conditions (doesnt' show well). Therefore your only resource is to actually go see it and for that you need a Realtor. Find a broker your feel comfortable with, usually our services are at no charge to you.
Work with a Realtor to help you identify your goals.
It may be best to find a broker who will work with you on your goal. Sometimes pictures on the MLS but many times Brokerages that obtain foreclosed listings only post the front of the building.
If you have a particular area that interest you most find a Broker who specializes in the area.
Best of Luck,

It's a lot of BS, but that is how the REO industry operates. THe MLS will show any pics, if they exist. Otherwise you just need to make an appointment.
