Do people actually use zillow for buying or just for perusing? Most of the listings on my zillow are these stale 60 day old listings where there is obviously something wrong with the listing, it doesn't look like the actual market that realtors are using considering homes here sell so fast. My understanding is real estate moves too quickly and you are going to be putting offers on homes your realtor shows you before they even hit market let alone aggregated on zillow.
