Underwriting requesting closing disclosure from a previous deal

[D'Andre B.]

Hello BP community, i'm in the final hours of a deal and underwriting is all of a sudden requesting that I hand over the closing disclosure from a deal that I closed 5 months ago. Has anyone ever experienced this? 

The other deal was an FHA owner occupied duplex. (My home) and the credit union wants to see the closing disclosure from this transaction. Why?

The new property is going to be used a rental, conventional loan, 15% down, and the credit union intends to sell to fannie mae.
