In Contract - How does Street Easy Know?

You should probably just ask them ;-)

The brokers post it on their webpages. . .

#2, yes I did send in a query to them a couple of days ago, but I haven't heard back so I thought I'd ask here. Perhaps I'll hear back from them at some point.

#3, that occured to me as well, but it seems kind of labor intensive for someone to go sifting through every listing's web page, no? I'm thinking it's done through a database that automatically feeds the info into Street Easy, but I was just curious.

Yes, brokers enter it into their database and intelligent agents (software things) can read it and record it.

The relationship between this site and the brokerages represented is less obviously than I personally would like.
