Real Estate Agents want to keep the Good Ones?

[Corazon B.]

So real estate agents have access to the MLS where they can see all of the properties currently available. And so they can see it before anybody else can, unless ofcourse you go door to door or do intense research on your own to find good deals without real estate license. If real estate agents recommend a property, I always think why couldn't they buy this themselves if this is a good deal? Why are the properties even there in the listings for more than 30 days?
