using zillow for market values?

[Robert Granara]

ive been using zillow.com for awhile to view estimates on properties...anyone else using this site?...

whats your take on the estimates provided?...it varies from market to market but on a whole how accurate do you think it is?

for example, i have a few properties that zillow estimates at $380K...these are bank owned multi families that need minor work, and can be picked up for around $200-$220K...there are a few of these out there in this mkt

can zillow be off that much?...what do you think...also im not looking to flip...im looking to buy and hold and rent for cash flow...
