I've found the most reliable comps are MLS - because the MLS is retail, and those systems are so heavily regulated there is much less of a chance for shenanigans and price BS'ing (still a chance, but much less). zillow, trulia, eppraisal, other online resources are usually completely out of whack and I don't give them an ounce of credibility.
