I have a list of REOs, which ones should I get comps for?

[Mikel Graham]

Ok, so I've been struggling a bit here. I recently received a list of REOs in my area. I've been trying to find similar properties that have sold recently and I am unable to find a single comp for the 30 listings I have access to.

Ultimately, I will need to request comps from my realtor and perhaps a title company. However, I have a much more fundamental question...

How do I decide which of these properties I should get comps on? I really don't want to waste anybody's time by asking for comps on everything. How do I narrow down my search?
