Mandatory Caliber Home Loans pre-qual?

[Vonetta Booker]

On the MLS in my area of CT, I've seen several REO listings that state that in order to make an offer, the buyer must get prequalified through Caliber Home Loans. We already have a prequal letter from another lender, but the seller/bank insists on the Caliber prequal.

Has anyone ever heard of this type of thing with REO offers (or with Caliber in particular)? I just find it a bit strange that they'd insist on that--if one has a valid prequal letter or POF, what should it matter, right? I'm just trying to have as little hard pulls on my credit as possible.
