Don't make assumptions by a two line post that I made. I do pick my comps after I have seen the property. Always have, Always will. But I try to print several sales in a given neighborhood before I visit. Inevitably, I have to print more after I have seen the property, that is why I recently purchased a laptop so I don't have to drive all the way back to the office to get new sales when the sales that I printed before hand don't match or approximate all the attributes of the subject. All I am trying to communicate is that this is a tool that can be used in our field. When you can see the subject property before you actually visit, you can identify the design, quality, and have a general idea of the size based on any available public records. I am not condoning use of this tool to circumvent any due dilligence that is required in this job, but it is nice to have an idea what you are going to go see before you see it.
I know that so many of you guys on this forum love to pounce on someone as soon as you get the chance thinking... "See!!! I Told them!!!"
