Yes that is how you do it but a lot of it is manual and the site now times you out during the searches. It is easy enough to get back in but becomes more trouble than its worth if trying to do it on a large scale. Generally if Im in the market I will usually pull the last 3 to 4 weeks of data for a particular resort. Normally you can weed out the foreclosures easily enough.
