An REO Title Deed Question

[Scott Hawley]

I found some REOs and when I was backtracking the title (through the assessors website) I found that the proeprty changed hands several times in the space of 1 or 2 months time. Some of the deeds that were recorded were quit claim and some were warranty. I am wondering if one of those transactions did not get recorded (essentially clouding the title to the property), would there be a fine from the assessors office?
Can a property change hands several times through quit claim deeds and w/o being recorded?
I would appreciate any answers and advice on this matter.
