Relists bother me. I think buyers should know a house's true number of days on market and when a house gets relisted, that stat gets distorted.
So if you come across a relist and have the time, post it to this thread. Maybe someone looking to buy that house will come across this information and appreciate it.
Generally you can querry the address in Google and then used cached pages to find the older listing. Once you have the MLS you can querry on "MLS Seattle <MLS Number>" and sometimes get better results.
Realtors must hate Google's cache.
