Eppraisal vs. Zillow?

[Mikel Graham]

I'm looking various properties to potentially place bids on. However, I'm noticing a large disparity between the Eppraisal and Zillow values are some of the properties. Here's an example below...

Eppraisal: $60,456
Zillow: $16,800

How should I interpret this information. The list price for the property is $10,800 and in the auction phase (if that makes any difference).

Would this be worth going after at all? Why or why not?

Thanks,

M
