REO's changing brokers frequently

[Ingrid Nagy]

I've noticed that some of the lenders are changing brokers after a few months or withdrawing their listings and signing up with other brokers with lower listing prices. Is this customary? I'm also finding some "internet" brokers advertising listings as if they are their own. They come up as #1 when I search a specific address and I later find it was never their listiing at all. It becomes frustrating.
